S89.222A Salter-Harris Type II physeal fracture of upper end of left fibula, initial encounter for closed fracture

Name of the Condition

• Salter-Harris Type II physeal fracture of upper end of left fibula, initial encounter for closed fracture
• Also known as: Type II growth plate fracture of the proximal left fibula (closed, initial encounter)

Summary

A Salter-Harris Type II physeal fracture of the upper end of the left fibula is an injury to the growth plate (physis) at the proximal left fibula, typically occurring in children and adolescents. This fracture involves a separation through the growth plate with a metaphyseal fragment, distinguishing it from other Salter-Harris types. The term "initial encounter" indicates this is the first episode of care for the closed fracture, where the skin remains intact.

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. The closed nature of the fracture means the overlying skin is not broken.

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 left 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 type and location. The closed nature of the fracture is determined by the absence of skin disruption.

Treatment Options

Treatment may include immobilization with a cast or splint to allow healing. Pain management and activity modification are often recommended. In some cases, surgical intervention may be necessary to realign the fracture.

Prognosis and Follow-Up

Prognosis is generally favorable with appropriate treatment, though long-term monitoring may be needed to assess growth plate function. Follow-up appointments are important to ensure proper healing and to address any potential complications.

Complications

Potential complications include growth plate damage leading to limb length discrepancy or angular deformity, infection (if open), or delayed union. Early intervention reduces these risks.

Lifestyle & Prevention

Avoid high-impact activities until cleared by a healthcare provider. Use protective gear during sports. Strengthening exercises and proper technique may reduce injury risk.

When to Seek Professional Help

Seek immediate care for severe pain, inability to bear weight, visible deformity, or signs of infection (e.g., fever, increased swelling). Prompt evaluation is critical for proper management.

Tips for Medical Coders

Document the fracture type (Salter-Harris II), location (upper end of left fibula), encounter type (initial), and fracture status (closed). Ensure clinical notes specify the absence of skin penetration to support the "closed" designation.
