S89.02 Salter-Harris Type II physeal fracture of upper end of tibia

Name of the Condition

• Salter-Harris Type II physeal fracture of upper end of tibia

Summary

A Salter-Harris Type II physeal fracture of the upper end of the tibia is a growth plate injury affecting the proximal tibia, typically occurring in children and adolescents. This fracture involves a separation through the growth plate (physis) with a metaphyseal fragment, disrupting bone development in the area.

Causes

Common causes include trauma from falls, sports injuries, or accidents where force is applied to the knee or lower leg. Direct impact, twisting motions, or axial loading can disrupt the growth plate, leading to this type of fracture.

Risk Factors

• Age: More common in children and adolescents due to open growth plates.
• Activity Level: Participation in contact sports or activities with a risk of leg trauma.
• Anatomical Factors: Variations in bone structure or growth plate vulnerability.

Symptoms

• Pain and tenderness around the knee or proximal tibia.
• Swelling and possible bruising near the affected area.
• Difficulty or reluctance to bear weight on the affected leg.
• Limited range of motion in the knee.

Diagnosis

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

Treatment Options

Treatment depends on fracture severity and displacement. Non-displaced fractures may be managed with immobilization (e.g., casting) and activity restriction. Displaced fractures often require closed reduction or surgical intervention to realign the bone. Follow-up imaging ensures proper healing.

Prognosis and Follow-Up

Prognosis is generally favorable with appropriate treatment, though growth plate damage may affect future bone development. Regular follow-up with imaging and clinical assessments monitors healing and growth. Long-term monitoring may be needed if growth disturbances are suspected.

Complications

Potential complications include growth plate arrest, limb length discrepancy, angular deformity, or chronic pain. Infection or nonunion may occur with surgical intervention. Early recognition and management reduce 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. Ensure adequate calcium and vitamin D intake for bone health.

When to Seek Professional Help

Seek immediate care for severe pain, inability to bear weight, visible deformity, or signs of infection (e.g., fever, redness). Persistent pain, swelling, or limited mobility after injury also warrants evaluation.

Tips for Medical Coders

Document the fracture type (Salter-Harris II) and location (upper end of tibia) clearly. Include details on displacement, treatment, and follow-up to support coding accuracy. Ensure documentation aligns with clinical findings and imaging results.
