S89.221 Salter-Harris Type II physeal fracture of upper end of right fibula

Name of the Condition

• Salter-Harris Type II physeal fracture of upper end of right fibula
• Also known as: Type II growth plate fracture of the proximal right fibula

Summary

A Salter-Harris Type II physeal fracture of the upper end of the right fibula is an injury to the growth plate (physis) at the proximal fibula, typically occurring in children and adolescents. This type of fracture involves a separation through the growth plate with a metaphyseal fragment, which is a critical area for bone development. The fracture pattern includes a break through the physis and a portion of the metaphysis.

Causes

Common causes include trauma from falls, sports injuries, or accidents where an impact or stress is applied to the leg. Direct force or twisting motions can disrupt the growth plate, leading to this specific fracture pattern.

Risk Factors

• Age: More common in children and adolescents due to open growth plates.
• Activity Level: Participation in contact sports or activities that may cause physical impact.
• Anatomical Factors: Variations in bone structure or growth plate vulnerability.

Symptoms

• Pain and tenderness around the fibula.
• Swelling and possible bruising near the affected area.
• Difficulty or reluctance to move the affected leg.
• Visible deformity in severe cases.

Diagnosis

Physical examination to assess pain, swelling, and range of motion. Imaging tests, such as X-rays, are typically used to confirm the fracture pattern, including separation at the growth plate and a metaphyseal fragment. Additional imaging may be required if other injuries are suspected.

Treatment Options

• Immobilization: Use of a cast or splint to allow healing.
• Rest: Limiting movement to ensure proper recovery.
• Treatment focuses on stabilizing the fracture to prevent growth disturbances.

Prognosis and Follow-Up

Prognosis is generally favorable with appropriate treatment, but follow-up is important to monitor for growth plate complications. Regular assessments may be needed to ensure proper healing and alignment.

Complications

• Growth plate disturbances leading to limb length discrepancies.
• Malunion or nonunion of the fracture.
• Chronic pain or stiffness in the affected area.

Lifestyle & Prevention

• Avoid high-impact activities until cleared by a healthcare provider.
• Use protective gear during sports to reduce injury risk.
• Maintain bone health through proper nutrition and exercise.

When to Seek Professional Help

Seek immediate medical attention if there is severe pain, visible deformity, or inability to bear weight on the affected leg. Persistent symptoms after initial treatment also warrant evaluation.

Tips for Medical Coders

Document the specific Salter-Harris Type II classification and the right fibula location. Ensure clinical documentation supports the fracture pattern, including the metaphyseal fragment, to justify the code. Verify laterality (right) and anatomical site for accurate coding.
