S99.032A Salter-Harris Type III physeal fracture of left calcaneus, initial encounter for closed fracture

Name of the Condition

• Salter-Harris Type III physeal fracture of left calcaneus, initial encounter for closed fracture
• Growth plate fracture of the left heel bone (Type III), closed, initial encounter

Summary

This condition involves a Salter-Harris Type III fracture of the growth plate (physis) in the left calcaneus (heel bone), occurring during the initial encounter for a closed fracture. Type III fractures extend through the growth plate and into the joint surface, requiring careful assessment to address both bone and joint involvement. It is typically seen in children or adolescents with developing bones.

Causes

Direct trauma to the heel, such as falls, sports injuries, or accidents, can cause this fracture. The force disrupts the growth plate and extends into the joint, often from high-impact or twisting motions affecting the foot.

Risk Factors

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

Symptoms

• Pain and swelling localized to the heel.
• 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 used to confirm the fracture type and assess joint involvement. The closed nature of the fracture (no skin breach) is documented during evaluation.

Treatment Options

Treatment focuses on realigning the fracture and stabilizing the joint. This may include casting, bracing, or surgical intervention for displaced fractures. Closed reduction is preferred when possible, with follow-up imaging to ensure proper healing.

Prognosis and Follow-Up

Prognosis depends on the accuracy of reduction and the extent of joint involvement. Regular follow-up with imaging is necessary to monitor growth plate integrity and joint alignment. Long-term outcomes may include functional recovery, though some risk of growth disturbance exists.

Complications

Potential complications include growth plate damage leading to limb length discrepancy, joint stiffness, or arthritis. Incomplete reduction or delayed treatment may increase these risks.

Lifestyle & Prevention

Avoid high-impact activities until cleared by a healthcare provider. Use protective footwear during sports. Strengthening exercises and proper warm-ups may reduce injury risk in susceptible individuals.

When to Seek Professional Help

Seek immediate care for severe pain, inability to bear weight, or visible deformity. Persistent swelling, fever, or signs of infection (e.g., redness, drainage) also warrant prompt evaluation.

Tips for Medical Coders

Document the fracture type (Salter-Harris III), laterality (left), encounter type (initial), and fracture status (closed). Ensure clinical notes specify the growth plate involvement and joint surface extension to support code assignment.
