S89.03 Salter-Harris Type III physeal fracture of upper end of tibia

Name of the Condition

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

Summary

A Salter-Harris Type III physeal fracture of the upper end of the tibia is a specific growth plate injury affecting the proximal tibia, typically occurring in children and adolescents. This fracture involves a break through the growth plate (physis) that extends into the epiphysis, 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 the fracture pattern and evaluate growth plate involvement. 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 modification. Displaced fractures often require surgical intervention to realign the bone and stabilize the growth plate. Post-treatment, physical therapy may be recommended to restore function.

Prognosis and Follow-Up

Prognosis varies based on fracture severity, treatment, and growth plate involvement. Regular follow-up with imaging is important to monitor for growth disturbances or complications. Long-term outcomes depend on proper alignment and adherence to rehabilitation.

Complications

Potential complications include growth plate arrest, limb length discrepancy, angular deformity, or arthritis. Early detection and appropriate management reduce these risks.

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 balanced nutrition and regular exercise.

When to Seek Professional Help

Seek immediate medical attention for severe pain, inability to bear weight, visible deformity, or signs of infection (e.g., fever, redness). Follow up with a healthcare provider if symptoms worsen or do not improve with initial treatment.

Tips for Medical Coders

Document the fracture type (Salter-Harris Type III) and specify involvement of the upper tibial growth plate. Include details on displacement, treatment, and any complications to support accurate coding. Ensure documentation aligns with clinical findings and imaging results.
