S99.042 Salter-Harris Type IV physeal fracture of left calcaneus

Name of the Condition

• Salter-Harris Type IV physeal fracture of left calcaneus
• Growth plate fracture of the left heel bone (Type IV)

Summary

This condition involves a Salter-Harris Type IV fracture affecting the growth plate (physis) of the left calcaneus (heel bone). Type IV fractures extend through the growth plate, metaphysis, and epiphysis, potentially disrupting both bone growth and joint alignment. It is an injury to the developing bone structure, typically seen in children or adolescents, and requires careful evaluation to guide treatment and prevent complications.

Causes

Direct trauma or injury to the heel, such as falls, sports-related impacts, or accidents. Sudden force applied to the foot, which can disrupt the growth plate and adjacent bone structures.

Risk Factors

• Age: Children and adolescents, as their growth plates are still developing and more susceptible to injury.
• High-impact activities: Participation in sports like running, jumping, or contact sports.
• Previous injuries: Prior damage to the heel or surrounding structures may increase vulnerability.

Symptoms

• Pain and swelling localized to the heel area.
• Difficulty bearing weight or walking on the affected foot.
• Limited range of motion in the ankle or foot.
• Visible bruising or deformity in severe cases.

Diagnosis

Physical examination to assess pain, swelling, and functional limitations. Imaging studies, such as X-rays or CT scans, are typically used to confirm the fracture type, assess displacement, and evaluate joint involvement.

Treatment Options

Treatment depends on fracture severity and displacement. Options may include immobilization with a cast or splint, closed reduction (realignment without surgery), or open reduction and internal fixation (surgery) for displaced fractures. Follow-up care focuses on monitoring healing and preventing complications.

Prognosis and Follow-Up

Prognosis varies based on fracture severity, treatment, and adherence to follow-up. Regular monitoring is essential to assess bone growth and joint alignment. Long-term follow-up may be needed to detect potential complications like growth disturbances or arthritis.

Complications

Potential complications include growth plate damage leading to limb length discrepancy or angular deformity, post-traumatic arthritis, or chronic pain. Early intervention and proper management reduce these risks.

Lifestyle & Prevention

Avoid high-impact activities until cleared by a healthcare provider. Use appropriate protective gear during sports. Strengthen foot and ankle muscles to improve stability. Ensure safe environments to minimize fall risks.

When to Seek Professional Help

Seek immediate care for severe pain, inability to bear weight, visible deformity, or signs of infection (e.g., fever, increased swelling). Prompt evaluation is critical to prevent long-term complications.

Tips for Medical Coders

Code S99.042 is specific to a Salter-Harris Type IV physeal fracture of the left calcaneus. Ensure documentation specifies the fracture type, location (left calcaneus), and any associated details (e.g., open/closed, displacement) to support accurate coding. Verify laterality and fracture characteristics align with clinical findings.
