S99.03 Salter-Harris Type III physeal fracture of calcaneus

Name of the Condition

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

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 tests, such as X-rays or MRI, to evaluate the fracture and growth plate involvement, including the epiphysis and joint surface.

Treatment Options

• Immobilization with a cast or brace to stabilize the area and promote healing.
• Surgical intervention may be required if the fracture involves the joint surface or is displaced.
• Physical therapy to restore strength and mobility after healing.

Prognosis and Follow-Up

Prognosis depends on the severity of the fracture and the accuracy of treatment. Regular follow-up is necessary to monitor growth and joint function. Long-term outcomes may include potential growth disturbances or joint issues if the fracture affects the epiphysis or joint alignment.

Complications

• Growth disturbances or limb length discrepancies.
• Joint stiffness or arthritis if the fracture involves the joint surface.
• Nonunion or malunion of the fracture.

Lifestyle & Prevention

• Use appropriate protective gear during sports or high-impact activities.
• Avoid activities that place excessive stress on the heel until fully healed.
• Maintain overall bone health with proper nutrition and exercise.

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., redness, fever).

Tips for Medical Coders

Document the specific Salter-Harris Type III classification and any associated details, such as displacement or joint involvement, to ensure accurate coding. Include clinical notes supporting the fracture type and treatment provided.
