Köhler’s disease, also spelled Kohler’s disease, is an uncommon osteochondrosis affecting the tarsal navicular bone in children. First described in 1908 by the German radiologist Alban Köhler, the condition is characterized by avascular necrosis of the navicular, leading to pain, limping, and radiographic changes that reflect delayed ossification and temporary bone collapse. Although the disorder can be alarming to parents due to its painful presentation, it is self?limiting and carries an excellent long?term prognosis.

Epidemiology

Köhler’s disease primarily affects children between the ages of 4 and 7, though some sources report a broader range of 2 to 9 years. It is significantly more common in boys, with male?to?female ratios reported between 4:1 and 6:1.

Most cases are unilateral, though bilateral involvement occurs in up to 15–25% of children. The condition is rare overall, and its self?limiting nature may contribute to underdiagnosis.

Anatomy and Development of the Navicular

The navicular bone sits in the medial midfoot and plays a crucial role in maintaining the arch and facilitating normal foot mechanics. It is the last tarsal bone to ossify, typically around age 3–5. Because its ossification center appears later than those of surrounding bones, the navicular is particularly vulnerable to mechanical stress during early childhood.

The central third of the navicular receives relatively limited blood supply, creating a “watershed zone” that predisposes it to ischemic injury.

Pathophysiology

Köhler’s disease is considered an osteochondrosis, a group of disorders involving temporary interruption of blood supply to developing bone. In this condition, the navicular undergoes avascular necrosis, leading to collapse, sclerosis, and fragmentation visible on radiographs.

The exact cause remains unknown, but several contributing factors have been proposed:

• Mechanical compression: As children begin to walk and run, the navicular—still cartilaginous—may be compressed between the talus and cuneiforms. This pressure can compromise blood flow.
• Repetitive microtrauma: High activity levels may exacerbate stress on the immature bone.
• Vascular vulnerability: The limited blood supply to the central navicular increases susceptibility to ischemia.
• Possible traumatic triggers: Some clinicians note that minor injuries may precede symptoms, though this is not universal.

Regardless of the initiating factor, the result is temporary necrosis followed by eventual revascularization and remodeling.

Clinical Presentation

Children with Köhler’s disease typically present with:

• Pain along the medial or dorsal midfoot
• Tenderness over the navicular
• Swelling, redness, or warmth in some cases
• Limping or refusal to bear weight
• Gradual onset rather than sudden injury-related pain

Symptoms often worsen with activity and improve with rest. Parents may report that the child avoids walking long distances or prefers to crawl or be carried.

Diagnosis

Diagnosis is primarily clinical, supported by radiographic findings.

Radiographic Features

X?rays typically show:

• Sclerosis of the navicular
• Fragmentation
• Flattening or collapse of the bone
• Delayed ossification compared to the contralateral side

These findings reflect the necrotic and reparative phases of the disease. Radiographs are usually sufficient; advanced imaging is rarely necessary.

Differential Diagnosis

Because midfoot pain in children can arise from various causes, clinicians must consider:

• Accessory navicular syndrome
• Navicular stress fracture
• Osteomyelitis
• Tarsal coalition
• Juvenile idiopathic arthritis

The characteristic age range and radiographic appearance usually distinguish Köhler’s disease from these conditions.

Management

Treatment is nonoperative and focuses on symptom relief while the bone heals naturally.

Conservative Measures

• Activity modification: Reducing running, jumping, and prolonged walking helps alleviate symptoms.
• NSAIDs: Nonsteroidal anti-inflammatory drugs reduce pain and inflammation.
• Immobilization: A short period (3–6 weeks) in a below?knee walking cast is often recommended for children with significant pain. This reduces mechanical stress and accelerates symptom resolution.
• Supportive footwear or orthotics: These may help redistribute pressure across the midfoot.

Why Casting Helps

Immobilization decreases the compressive forces that contribute to ischemia, allowing revascularization and bone remodeling to proceed more comfortably.

Prognosis

The prognosis for Köhler’s disease is excellent. Most children recover fully within 6–18 months, and long?term complications are extremely rare. The navicular typically remodels to a normal shape and density as blood supply returns and ossification completes.

Residual deformity or chronic pain is uncommon, and children generally return to full activity without limitations.

Discussion

Köhler’s disease exemplifies the unique vulnerabilities of the pediatric skeleton. The combination of delayed ossification, mechanical stress, and limited vascularity creates a perfect storm for temporary bone injury in the navicular. Yet the condition also highlights the remarkable regenerative capacity of children’s bones.

From a clinical standpoint, the key challenge lies in recognizing the disorder and distinguishing it from more serious conditions such as infection or fracture. Once diagnosed, reassurance is essential: despite dramatic radiographic changes, the disease is self?limiting.

The condition’s male predominance and typical age range suggest developmental and biomechanical influences, though the precise etiology remains uncertain. Future research may clarify the interplay between vascular anatomy, mechanical loading, and genetic factors.

Köhler’s disease of the navicular is a rare, self?limiting osteochondrosis that affects young children, particularly boys. Characterized by temporary avascular necrosis of the navicular bone, it presents with midfoot pain, limping, and characteristic radiographic changes. Diagnosis is straightforward with clinical evaluation and X?rays, and treatment is conservative, focusing on rest, NSAIDs, and short?term immobilization when necessary.

The long?term outlook is overwhelmingly positive, with most children experiencing complete recovery and no lasting deformity. Understanding this condition allows clinicians to provide effective care and reassurance to families, ensuring that children return to normal activities with confidence.

Iselin’s disease is a relatively uncommon but important orthopedic condition that affects children and adolescents during periods of rapid growth. Characterized by pain and inflammation along the outer edge of the foot, the condition can significantly impact mobility, athletic participation, and overall quality of life. Although the name may sound alarming, Iselin’s disease is a temporary, self?limiting condition that resolves once skeletal maturity is reached. Understanding its causes, symptoms, diagnosis, and treatment is essential for parents, clinicians, and young athletes who may encounter this condition.

Anatomical Background

To understand Iselin’s disease, it is helpful to first examine the anatomy involved. The condition affects the apophysis, or growth plate, located at the base of the fifth metatarsal, the long bone on the outer side of the foot that connects to the little toe. This bony prominence, known as the styloid process, serves as the attachment point for the peroneus brevis tendon, a muscle responsible for everting the foot. In growing children, this apophysis is made of cartilage and is therefore more vulnerable to stress and traction forces than mature bone.

According to clinical descriptions, Iselin’s disease occurs when this growth plate becomes irritated or inflamed due to repetitive stress or overuse. Because the apophysis is an area of relative weakness during growth spurts, it is particularly susceptible to injury in active children.

Causes and Risk Factors

The exact cause of Iselin’s disease is not fully understood, but the prevailing theory is that it results from repetitive traction of the peroneus brevis tendon on the developing growth plate. Activities that involve running, jumping, cutting, or rapid directional changes—common in sports such as soccer, basketball, gymnastics, and dance—place repeated stress on the lateral foot.

Multiple sources emphasize that the condition most often affects children between 8 and 14 years old, with a peak incidence during growth spurts when the apophysis is most active and vulnerable. Young athletes are particularly at risk due to the combination of skeletal immaturity and high levels of physical activity.

Other contributing factors may include:

• Poorly fitting footwear
• Sudden increases in training intensity
• Foot biomechanics such as high arches or supination
• Direct trauma to the outer foot

Although the condition is sometimes referred to as a “disease,” it is not infectious or systemic; rather, it is a localized overuse injury.

Clinical Presentation

The hallmark symptom of Iselin’s disease is pain along the outer border of the foot, specifically at the base of the fifth metatarsal. The pain typically worsens with physical activity and improves with rest. Children may describe the discomfort as aching, sharp, or throbbing.

Common signs and symptoms include:

• Localized swelling or tenderness over the styloid process
• Pain during running, jumping, or pushing off the foot
• Difficulty wearing tight shoes due to irritation of the bony prominence
• A limp or altered gait in more severe cases

Some children may also experience redness or warmth over the affected area, though these symptoms are less common.

Because the symptoms can mimic other conditions—such as fractures, tendon injuries, or infections—accurate diagnosis is essential.

Diagnosis

Diagnosis of Iselin’s disease is primarily clinical, based on history and physical examination. A clinician will typically palpate the outer foot to identify tenderness over the apophysis and assess pain during resisted foot eversion.

Imaging may be used to confirm the diagnosis or rule out other conditions. X?rays can show fragmentation or irregularity of the apophysis, although these findings can also be normal variants in growing children. Therefore, radiographic interpretation must be made in the context of clinical symptoms.

Advanced imaging such as MRI is rarely needed but may be used in atypical or severe cases.

Treatment and Management

Fortunately, Iselin’s disease is a self?limiting condition, meaning it resolves naturally once the growth plate closes. Treatment focuses on symptom relief and reducing stress on the affected area.

Conservative Management

Most cases respond well to conservative measures, including:

• Rest and activity modification: Reducing or temporarily stopping high?impact activities allows the apophysis to heal.
• Ice therapy: Applying ice helps reduce inflammation and pain.
• Non?steroidal anti?inflammatory drugs (NSAIDs): These may be used for short?term pain relief, though medical guidance is recommended.
• Footwear adjustments: Supportive shoes or orthotics can reduce traction on the peroneus brevis tendon.
• Stretching and strengthening: Physical therapy may focus on calf and peroneal muscle flexibility to reduce tension on the growth plate.

According to pediatric orthopedic sources, symptoms typically improve within several weeks of appropriate management.

Immobilization

In more severe or persistent cases, short?term immobilization using a walking boot or cast may be recommended to fully offload the foot and allow healing.

Return to Activity

Children can gradually return to sports once they are pain?free during daily activities and physical examination shows no tenderness. Because the condition cannot recur after skeletal maturity, long?term prognosis is excellent.

Differential Diagnosis

Because lateral foot pain in children can have multiple causes, clinicians must distinguish Iselin’s disease from:

• Avulsion fractures of the fifth metatarsal
• Jones fractures
• Peroneal tendonitis
• Stress fractures
• Infection or inflammatory conditions

Accurate diagnosis prevents unnecessary immobilization or prolonged activity restriction.

Impact on Mobility and Quality of Life

Although temporary, Iselin’s disease can significantly affect a child’s participation in sports and daily activities. Young athletes may struggle with reduced performance, missed practices, or frustration due to pain. Early recognition and appropriate management help minimize disruption and support a safe return to activity.

Sources emphasize that understanding the condition is crucial for parents and coaches, as pushing through pain can worsen symptoms and prolong recovery .

Iselin’s disease is a growth?related overuse injury affecting the apophysis of the fifth metatarsal in children and adolescents. While it can cause significant discomfort and limit physical activity, the condition is benign, temporary, and highly responsive to conservative treatment. Awareness of its symptoms, causes, and management strategies allows for early intervention and helps young athletes maintain healthy participation in sports. With proper care, children typically recover fully and experience no long?term complications once skeletal maturity is reached.

Growing pains are one of the most frequent complaints among children, particularly between the ages of 3 and 12. Despite their name, growing pains are not directly linked to physical growth. Instead, they represent a benign but sometimes distressing phenomenon characterized by aching or cramping sensations in the legs, usually occurring in the late afternoon, evening, or during the night. This essay explores the history, symptoms, causes, diagnosis, treatment, and psychosocial impact of growing pains, while also addressing misconceptions and the importance of distinguishing them from more serious conditions.

Historical Background

The term “growing pains” dates back to the 19th century, when physicians assumed that rapid bone growth was responsible for children’s leg aches. Modern research, however, has disproved the growth theory, showing that growth itself does not cause pain. Instead, the condition is now understood as a benign musculoskeletal pain syndrome.

Symptoms and Presentation

• Location: Pain is most often felt in the muscles of the thighs, calves, behind the knees, or shins .
• Timing: Episodes typically occur in the evening or at night, sometimes waking children from sleep.
• Pattern: The pain is intermittent, not daily, and may persist for months or years.
• Severity: While the pain can be intense, it does not cause lasting damage to bones or muscles.
• Activity: Children are usually pain-free during the day and remain active without limitations.

Causes and Theories

Although the exact cause remains unclear, several theories exist:

• Muscle fatigue: After a day of running, jumping, or playing, muscles may ache from overuse.
• Pain sensitivity: Some children may have lower thresholds for pain perception.
• Emotional factors: Stress or anxiety can amplify physical discomfort.
• Biomechanical factors: Flat feet or poor posture may contribute to leg strain.

Importantly, growing pains are not caused by growth spurts.

Diagnosis

Growing pains are diagnosed by exclusion. Physicians rely on:

• Medical history: Pain occurs at night, is bilateral, and does not limit daytime activity .
• Physical examination: Normal findings with no swelling, redness, or joint stiffness.
• Rule-out process: Ensuring the pain is not due to conditions like juvenile arthritis, infections, or bone tumors.

Treatment and Management

Growing pains are harmless and self-limiting, but supportive care helps:

• Massage: Gentle rubbing of the legs provides comfort .
• Heat therapy: Warm baths or heat packs soothe aching muscles .
• Stretching: Bedtime stretches may reduce nighttime pain.
• Pain relief: Occasional use of mild analgesics like acetaminophen may be recommended.
• Reassurance: Parents should be reassured that growing pains do not cause long-term harm.

Psychosocial Impact

Although medically benign, growing pains can affect:

• Sleep quality: Nighttime pain disrupts rest, leading to fatigue.
• Parental anxiety: Parents often worry about serious illness.
• Child’s emotional wellbeing: Repeated pain episodes may cause distress or fear of bedtime.

Distinguishing Growing Pains from Serious Conditions

It is crucial to differentiate growing pains from other causes of leg pain:

• Red flags: Persistent pain, swelling, redness, limping, or pain localized to one leg should prompt medical evaluation.
• Other conditions: Muscle strain, low calcium, juvenile arthritis, or even rare cancers can mimic growing pains.

Prognosis

Growing pains usually resolve by adolescence. They do not cause permanent damage, and children outgrow them naturally

---

Growing pains are a common, benign, and self-limiting condition affecting children’s legs. While the exact cause remains uncertain, they are not linked to growth itself. With reassurance, simple home remedies, and awareness of warning signs, families can manage growing pains effectively. Importantly, distinguishing them from more serious conditions ensures children receive appropriate care when needed.

Walking is one of the most fundamental human movements, yet it is far from simple. The biomechanics of gait involve a complex interplay between bones, muscles, ligaments, and neurological control. When this system is disrupted, even slightly, it can lead to abnormal walking patterns such as in-toeing (pigeon-toed walking) or out-toeing. These conditions may appear harmless but can cause tripping, imbalance, and long-term musculoskeletal issues. One of the most effective orthotic interventions for these problems is the gait plate.

What Are Gait Plates?

• Definition: A gait plate is a rigid extension added to the front of a foot orthotic or insole. It is designed to change the angle of gait by influencing how the shoe bends across the ball of the foot.
• Materials: They are typically made from rigid materials such as polypropylene or carbon fiber, ensuring durability and effectiveness.
• History: First described in 1967 by Richard O. Schuster, gait plates were introduced as a device to influence the angle of gait in children.

How Do Gait Plates Work?

• Biomechanical Principle: By altering the flexion line of the shoe at the metatarsophalangeal joints, gait plates induce forces that rotate the lower limb either internally or externally.
• For In-Toeing: The distal edge of the orthotic is cut proximal to the fifth metatarsal head and extended from the first metatarsal head to the sulcus of the first toe. This encourages external rotation, guiding the foot outward.
• For Out-Toeing: The design is reversed, promoting internal rotation to bring the feet inward.
• Effectiveness: Success varies depending on the underlying cause of the gait abnormality, such as tibial torsion, femoral rotation, or forefoot deformities

Clinical Applications

1. Treatment of In-Toeing

• Common in children, in-toeing can result from metatarsus adductus, tibial torsion, or femoral anteversion .
• Gait plates help by gently guiding the feet outward, reducing tripping and improving walking confidence.

2. Treatment of Out-Toeing

• Less common than in-toeing but can also cause instability.
• Gait plates encourage inward rotation, correcting the outward deviation.

3. Postural and Balance Improvement

• By aligning the feet properly, gait plates enhance overall posture and balance, reducing the risk of falls.

4. Preventing Secondary Issues

• Untreated gait abnormalities can lead to knee pain, hip misalignment, or even lower back problems.
• Early intervention with gait plates can prevent these complications .

Advantages of Gait Plates

• Non-invasive: They provide a conservative alternative to surgery.
• Customizable: Can be tailored to the child’s specific gait pattern.
• Effective in Children: Particularly useful during growth years when bones and muscles are more adaptable.
• Improves Confidence: Children who trip less often gain confidence in physical activities.

Limitations and Controversies

• Variable Success: Effectiveness depends on the cause of gait abnormality. Some children respond well, while others show minimal improvement.
• Obsolescence Debate: Some podiatrists argue that gait plates may be outdated, with limited research supporting their long-term benefits.
• Adaptation Period: Children may initially find them uncomfortable, requiring time to adjust.
• Not a Universal Solution: They are most effective for mild to moderate cases; severe deformities may require surgical intervention.

Case Studies and Evidence

• Clinical Observations: Many practitioners report positive outcomes in children with in-toeing, noting reduced tripping and improved gait.
• Research Gaps: Despite anecdotal success, there is limited large-scale research proving their long-term efficacy.
• Parental Feedback: Parents often observe noticeable improvements in walking patterns and reduced falls when gait plates are used consistently.

Future Directions

• Improved Designs: Advances in materials and biomechanics may lead to more comfortable and effective gait plates.
• Integration with Smart Technology: Future orthotics may include sensors to monitor gait in real time, providing feedback and adjustments.
• Research Expansion: More clinical trials are needed to establish standardized guidelines for gait plate use.

Gait plates remain a valuable tool in pediatric podiatry, particularly for correcting in-toeing and out-toeing gait patterns. While their effectiveness can vary, they offer a non-invasive, customizable solution that improves posture, balance, and confidence in children. Despite debates about their relevance in modern practice, gait plates continue to play an important role in early intervention for gait abnormalities. Their future lies in innovation, research, and integration with advanced technologies to maximize their therapeutic potential.

Freiberg’s Disease—also known as Freiberg’s infraction—stands out as a relatively rare but impactful disorder. First described by Alfred H. Freiberg in 1914, this disease primarily affects adolescents and young adults, especially females, and can cause chronic pain in the forefoot. Understanding its causes, symptoms, diagnosis, and treatment options is crucial for both medical professionals and patients.

What is Freiberg’s Disease?

• Definition: Freiberg’s Disease is an osteochondrosis (a disorder of bone growth) involving the metatarsal head, most often the second metatarsal. It is essentially a localized form of avascular necrosis, meaning the bone tissue dies due to insufficient blood supply.
• Location: Most cases involve the second metatarsal head, though the third and fourth metatarsals can occasionally be affected
• Demographics: It is four to five times more common in females than males, with peak incidence between ages 13–18, often in physically active adolescents.

Causes and Risk Factors

The exact cause remains unclear, but several contributing factors have been identified:

• Repetitive trauma: Stress from activities like running, dancing, or sports can cause microfractures in the metatarsal head.
• Vascular insufficiency: Reduced blood flow leads to necrosis of bone tissue.
• Foot anatomy: A relatively long second metatarsal increases pressure on the joint, raising risk.
• Gender predisposition: Hormonal and biomechanical differences may explain higher prevalence in females.
• Footwear: High heels or poorly cushioned shoes can exacerbate forefoot stress.

Symptoms

Patients with Freiberg’s Disease typically present with:

• Pain in the ball of the foot, especially during weight-bearing activities.
• Stiffness and swelling around the metatarsophalangeal (MTP) joint.
• Restricted range of motion, particularly dorsiflexion of the toe.
• Tenderness when pressing on the affected metatarsal head.
• In advanced cases, joint deformity and arthritic changes may occur.

Diagnosis

Diagnosis involves a combination of clinical examination and imaging:

• X-rays: Reveal flattening of the metatarsal head, sclerosis (hardening), and joint space narrowing.
• MRI scans: Detect early changes in bone marrow and blood supply.
• Clinical history: Pain localized to the forefoot, worsened by activity, is a key indicator.

Staging of Freiberg’s Disease

The condition progresses through stages:

1. Early stage: Subtle pain, minimal radiographic changes.
2. Intermediate stage: Flattening of the metatarsal head, sclerosis visible.
3. Advanced stage: Collapse of the joint surface, arthritic degeneration, and deformity.

Treatment Options

Treatment depends on severity and stage:

Non-Surgical Management

• Activity modification: Reducing high-impact activities.
• Orthotics: Custom insoles to redistribute pressure.
• NSAIDs: To manage pain and inflammation.
• Immobilization: Short-term casting or stiff-soled shoes.

Surgical Management

Reserved for advanced cases:

• Debridement: Removal of necrotic tissue.
• Osteotomy: Surgical reshaping of the metatarsal head.
• Joint replacement or fusion: For severe arthritis.
• Bone grafting: Restores structure and blood supply.

Impact on Patients

• Quality of life: Chronic pain can limit sports, walking, and daily activities.
• Psychological effects: Adolescents may struggle with reduced mobility and social participation.
• Long-term risks: Untreated disease can lead to permanent deformity and arthritis

Freiberg’s Disease, though rare, is a serious orthopedic condition that primarily affects the second metatarsal head in young, active individuals. It results from a combination of repetitive trauma and vascular insufficiency, leading to bone necrosis and joint collapse. Early recognition is vital, as conservative treatments can prevent progression, while advanced cases may require surgery. With proper management, most patients can regain mobility and reduce pain, underscoring the importance of awareness among clinicians and patients alike.

Congenital vertical talus (CVT), also known as rocker-bottom foot, is a rare and complex congenital foot deformity characterized by a rigid flatfoot with a convex sole. This condition is typically diagnosed at birth and, if left untreated, can lead to significant functional impairment and discomfort later in life. Though uncommon, CVT poses diagnostic and therapeutic challenges that require early intervention and multidisciplinary care.

Anatomy and Pathophysiology

The talus is a small bone situated between the heel bone (calcaneus) and the bones of the lower leg (tibia and fibula), forming the ankle joint. It plays a crucial role in weight transmission and foot mobility. In congenital vertical talus, the talus bone is abnormally positioned in a vertical orientation, causing misalignment of the surrounding bones. This results in a dorsal dislocation of the navicular bone and a rigid flatfoot deformity. The foot appears convex on the bottom, with the forefoot dorsiflexed and abducted, and the hindfoot in equinovalgus due to contractures of the Achilles and peroneal tendons.

Epidemiology and Etiology

CVT is a rare condition, occurring in approximately 1 in 10,000 to 1 in 150,000 live births. It affects males more frequently than females, with a male-to-female ratio of about 2:1. In nearly half of the cases, both feet are involved. The etiology of CVT is multifactorial. While some cases are idiopathic, many are associated with underlying neuromuscular or genetic disorders. Conditions such as arthrogryposis multiplex congenita, spina bifida, cerebral palsy, and chromosomal abnormalities like trisomy 13, 14, 15, or 18 are commonly linked to CVT.

A positive family history is present in up to 20% of cases, and mutations in genes such as HOXD10, which influence limb development, have been implicated. The deformity results from soft tissue contractures and abnormal muscle-tendon dynamics, where tendons like the peroneus longus and posterior tibialis function as dorsiflexors instead of plantar flexors.

Clinical Presentation

The hallmark of CVT is the rocker-bottom appearance of the foot, which is usually evident at birth. The midfoot is dorsiflexed, the hindfoot is elevated, and the forefoot is abducted. The talar head is prominent and palpable in the medial plantar arch. Unlike flexible flatfoot conditions, CVT is rigid and does not improve with stretching or bracing. As the child begins to walk, gait abnormalities become apparent, such as a “peg-leg” or calcaneal gait due to poor push-off power and limited forefoot contact.

Diagnosis

Early and accurate diagnosis is essential for effective treatment. Pediatric orthopedic specialists typically perform a thorough physical examination and assess the child’s gait and foot alignment. Radiographic imaging is crucial for confirming the diagnosis. Standard views include anteroposterior (AP), oblique, and lateral foot X-rays. A forced plantar flexion lateral radiograph is particularly diagnostic, revealing persistent dorsal dislocation of the talonavicular joint and a vertically oriented talus. Meary’s angle, which measures the alignment between the talus and the first metatarsal, is often greater than 20°, indicating significant deformity.

Differential Diagnosis

CVT must be distinguished from other congenital foot deformities, such as calcaneovalgus foot and clubfoot. Calcaneovalgus is a flexible deformity that typically resolves with time or minimal intervention, whereas CVT is rigid and requires surgical correction. Clubfoot presents with a different set of deformities, including plantarflexion and inversion of the foot, and is often misdiagnosed in cases of CVT by less experienced clinicians.

Treatment

The primary goal of treatment is to achieve a functional, stable, and pain-free foot. Management typically begins with non-surgical methods such as serial manipulation and casting, which aim to gradually correct the deformity. However, due to the rigidity of CVT, these methods are often insufficient on their own.

Definitive treatment usually involves surgical intervention between 6 to 12 months of age. The procedure includes soft tissue release, reduction of the talonavicular joint, and stabilization using pins. In some cases, tendon transfers or osteotomies may be required to correct severe deformities. Postoperative care involves immobilization and physical therapy to ensure proper healing and function.

Prognosis

With timely and appropriate treatment, most children with Congenital vertical talus can achieve good functional outcomes. Surgical correction typically results in improved foot alignment, mobility, and gait. However, long-term follow-up is necessary to monitor for recurrence or complications such as stiffness, pain, or residual deformity. Children with associated neuromuscular or genetic conditions may have more complex treatment courses and variable outcomes.

Congenital vertical talus is a rare but serious pediatric foot deformity that requires early recognition and intervention. Its association with systemic conditions underscores the importance of a comprehensive evaluation. Advances in diagnostic imaging and surgical techniques have significantly improved outcomes for affected children. Multidisciplinary care involving orthopedic surgeons, geneticists, and physical therapists is essential to ensure optimal treatment and long-term function. As awareness of Congenital vertical talus grows, so does the potential for timely diagnosis and effective management, offering children a better quality of life and mobility.

Calcaneal apophysitis, commonly referred to as Sever’s disease, is a painful condition affecting the heel in growing children and adolescents. Despite its name, it is not a true disease but rather an overuse injury involving inflammation of the growth plate in the heel bone (calcaneus). This condition is particularly prevalent among physically active youth, especially those engaged in sports that involve running and jumping. Understanding the causes, symptoms, diagnosis, and treatment of calcaneal apophysitis is essential for parents, coaches, and healthcare providers to ensure timely intervention and recovery.

Pathophysiology

The calcaneus, or heel bone, develops from two ossification centers: one begins at birth, and the other typically appears after age 8. Complete ossification usually occurs by age 15. During this period, the growth plate (apophysis) at the back of the heel remains vulnerable to stress and strain. Calcaneal apophysitis arises when repetitive microtrauma—often from sports or physical activity—causes inflammation at this growth plate.

The Achilles tendon, which connects the calf muscles to the heel, inserts directly into the calcaneal apophysis. During growth spurts, bones often grow faster than muscles and tendons can adapt, leading to increased tension at this insertion point. This tension, combined with high-impact activities, can result in painful inflammation and disruption of the apophyseal cartilage.

Risk Factors

Several factors contribute to the development of calcaneal apophysitis:

• Age: Most commonly affects children aged 9 to 14, during periods of rapid growth.
• Activity Level: High-impact sports such as soccer, basketball, gymnastics, and track increase risk due to repetitive heel stress.
• Footwear: Flat shoes or cleats without heel elevation exacerbate stress on the heel.
• Biomechanics: Tight calf muscles, high plantar pressures, and poor foot mechanics (e.g., overpronation) may contribute.
• Obesity: Excess body weight can increase heel pressure, although evidence on this is mixed.

Clinical Presentation

Children with calcaneal apophysitis typically present with:

• Heel pain: Especially at the back or sides of the heel, worsened by activity and relieved by rest.
• Tenderness: Localized over the calcaneal apophysis.
• Swelling and warmth: Occasionally present.
• Limping or toe-walking: To avoid heel contact.
• Bilateral symptoms: Both heels may be affected, though one side is often worse.

Pain is often aggravated by running, jumping, or standing on tiptoes. The condition may develop gradually or suddenly, depending on activity levels and biomechanical stress.

Diagnosis

Diagnosis of calcaneal apophysitis is primarily clinical. A thorough history and physical examination are usually sufficient. Key diagnostic steps include:

• Palpation: Tenderness over the posterior heel.
• Functional tests: Pain during heel squeeze or toe walking.
• Imaging: X-rays are typically not helpful, as the appearance of the growth plate may be normal even in symptomatic children. However, imaging may be used to rule out other conditions such as fractures or infections. MRI can show marrow edema or retrocalcaneal bursitis in more complex cases.

Treatment

Calcaneal apophysitis is a self-limiting condition that resolves with skeletal maturity. However, symptom management is crucial to maintain activity levels and prevent long-term discomfort. Treatment strategies include:

Rest and Activity Modification

• Reducing or temporarily stopping high-impact activities.
• Switching to low-impact exercises like swimming or cycling.

Stretching and Physical Therapy

• Achilles tendon stretching: Both passive and active techniques help reduce tension on the heel.
• Calf muscle flexibility: Night splints or stretching routines can maintain muscle length during growth spurts.

Footwear and Orthotics

• Heel cups or pads: Provide cushioning and reduce strain.
• Elevated heels: Alleviate Achilles tension.
• Supportive shoes: Avoid flat soles and ensure proper arch support.

Medications

• NSAIDs: Nonsteroidal anti-inflammatory drugs like ibuprofen can relieve pain and inflammation.

Ice Therapy

• Applying ice packs to the heel after activity can reduce swelling and discomfort.

In severe cases, immobilization with a cast or walking boot may be necessary to allow complete rest of the heel.

Prognosis

The prognosis for calcaneal apophysitis is excellent. Most children recover fully with conservative treatment and return to normal activities within weeks to months. The condition typically resolves once the growth plate closes during adolescence. However, recurrence is possible if activity resumes too quickly or without proper biomechanical correction.

Prevention

Preventive measures can reduce the risk of developing calcaneal apophysitis:

• Gradual increase in activity: Avoid sudden spikes in training intensity.
• Proper warm-up and stretching: Especially for the calf muscles and Achilles tendon.
• Appropriate footwear: Use shoes with cushioning and heel support.
• Cross-training: Incorporate low-impact activities to reduce repetitive heel stress.
• Monitoring growth spurts: Adjust activity levels during periods of rapid growth.

---

Calcaneal apophysitis is a common and treatable condition in growing children, particularly those engaged in sports. While it can cause significant discomfort and limit activity, early recognition and appropriate management lead to excellent outcomes. By understanding the underlying causes and implementing preventive strategies, caregivers and healthcare providers can support young athletes through their growth and development without compromising their physical well-being.
