S99.029 Salter-Harris Type II physeal fracture of unspecified calcaneus

Name of the Condition

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

Summary

This condition involves a fracture affecting the growth plate (physis) of the calcaneus (heel bone), classified as Salter-Harris Type II. It occurs in the developing bone structure, typically in children or adolescents, and requires careful management to support healing and growth. Type II fractures involve a separation of the growth plate with a metaphyseal fragment, distinguishing them from other types.

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 pull a small piece of the adjacent metaphysis.

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, such as X-rays, is typically used to confirm the fracture type and rule out other injuries. The Salter-Harris classification helps determine the fracture pattern and guide treatment.

Treatment Options

Treatment depends on fracture severity and displacement. Options may include immobilization with a cast or splint, activity modification, and close monitoring. Severe cases may require surgical intervention to realign the bone fragments. Physical therapy is often recommended during recovery to restore strength and mobility.

Prognosis and Follow-Up

Most Salter-Harris Type II fractures heal well with appropriate treatment, especially when managed early. Follow-up care is essential to monitor healing and assess for growth disturbances. Long-term outcomes are generally favorable, but regular evaluations help ensure proper bone development.

Complications

Potential complications include growth plate damage leading to limb length discrepancies or angular deformities. Infection, delayed union, or nonunion may occur in severe or untreated cases. Prompt treatment 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. Supervise children during activities with 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., redness, fever). Persistent swelling, limited mobility, or new symptoms after initial treatment also warrant evaluation.

Tips for Medical Coders

Document the fracture type (Salter-Harris II) and specify the calcaneus as the affected bone. Note whether the side is specified (right/left) or unspecified. Include details on trauma mechanism, imaging results, and treatment provided to support code assignment. Ensure documentation aligns with clinical findings to justify the diagnosis.
