S99.039 Salter-Harris Type III physeal fracture of unspecified calcaneus

Name of the Condition

• Salter-Harris Type III physeal fracture of unspecified calcaneus
• Growth plate fracture of the heel bone (Type III, unspecified side)

Summary

This condition involves a fracture of the growth plate (physis) of the calcaneus (heel bone), classified as Salter-Harris Type III. It is a specific type of injury that occurs in the developing bone structure, typically in children or adolescents, and requires careful evaluation to guide treatment. Type III fractures extend through the growth plate and into the epiphysis (the end of the bone), potentially affecting joint surfaces.

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 extend into the epiphysis.

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 MRI, may be used to confirm the fracture type and assess joint involvement. The unspecified side designation indicates the affected limb was not documented.

Treatment Options

Treatment depends on fracture severity and displacement. Options may include immobilization with a cast or splint, activity modification, and close monitoring. Surgical intervention may be necessary for displaced fractures to realign the bone and preserve joint function.

Prognosis and Follow-Up

Prognosis varies based on fracture severity and treatment. Regular follow-up is essential to monitor healing, assess growth plate integrity, and prevent long-term complications. Physical therapy may be recommended to restore mobility and strength.

Complications

Potential complications include growth plate damage leading to limb length discrepancies or deformity, joint stiffness, or arthritis. Early intervention reduces these risks.

Lifestyle & Prevention

Avoid high-impact activities until cleared by a healthcare provider. Use proper footwear and protective gear during sports. Strengthening exercises for the foot and ankle may help prevent injuries.

When to Seek Professional Help

Seek immediate care for severe pain, inability to bear weight, visible deformity, or signs of infection (e.g., fever, redness). Prompt evaluation is critical to minimize complications.

Tips for Medical Coders

Use this code for Salter-Harris Type III physeal fractures of the calcaneus when the side is not specified. Ensure documentation supports the fracture type and absence of side specification. Verify that the injury is not better classified under a more specific code (e.g., right or left calcaneus) if details are available.
