S99.04 Salter-Harris Type IV physeal fracture of calcaneus

Name of the Condition

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

Summary

This condition involves a fracture affecting the growth plate (physis) of the calcaneus (heel bone), classified as Salter-Harris Type IV. It is a type of injury that occurs in the developing bone structure, typically in children or adolescents, and requires attention to ensure proper healing and growth. Type IV fractures involve a fracture line that extends through the metaphysis, physis, and epiphysis, often with displacement of bone fragments.

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 surrounding 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 tests, such as X-rays or MRI, to evaluate the fracture and growth plate involvement, including the extent of displacement and damage to surrounding structures.

Treatment Options

• Immobilization with a cast or brace to stabilize the area and promote healing.
• Surgical intervention may be required for displaced fractures to realign bone fragments and restore growth plate integrity.
• Pain management and physical therapy to support recovery and restore function.

Prognosis and Follow-Up

Prognosis depends on the severity of the fracture, timing of treatment, and potential growth plate damage. Regular follow-up with imaging is often necessary to monitor healing and assess for growth disturbances. Long-term outcomes may include normal growth or, in some cases, mild functional limitations.

Complications

• Growth plate disturbance leading to limb length discrepancy or angular deformity.
• Chronic pain or stiffness in the heel or ankle.
• Potential for arthritis or other long-term joint issues if the fracture affects joint surfaces.

Lifestyle & Prevention

• Use appropriate protective gear during high-impact activities.
• Ensure proper footwear and support to reduce stress on the heel.
• Gradual return to activity under medical guidance after injury to prevent re-injury.

When to Seek Professional Help

Seek immediate medical attention if there is severe pain, inability to bear weight, visible deformity, or signs of infection (e.g., fever, increased swelling, redness).

Tips for Medical Coders

Document the fracture type (Salter-Harris Type IV) and specify involvement of the calcaneus. Include details on displacement, treatment, and any associated complications to ensure accurate coding. Verify that the injury is clearly linked to the growth plate and not other bone structures.
