➕ Slipped Capital Femoral Epiphysis

 

✅ Definition & Epidemiology

• Slipped Capital Femoral Epiphysis is a common adolescent hip condition affecting the proximal femoral physis.
• More common in boys, with onset at 10-17 years (boys) and 8-15 years (girls).

 

✅ Pathophysiology

• Salter-Harris Type I growth plate injury due to mechanical stress and hormonal factors.
• Initial pre-slip phase: widened growth plate, physeal irregularity, and metaphyseal demineralization.
• Acute slip: Posteromedial displacement of the epiphysis.
• Chronic slip: Sclerotic physis, widened metaphysis (coxa magna).

 

✅ Radiographic Findings

• Frog-leg lateral view best visualizes posterior displacement.
• AP Hip View Findings:

 

✅ Key Takeaways

• Early detection is crucial for preventing complications.
• Frog-leg lateral view is superior to AP for diagnosis.
• Look for Klein’s line disruption and metaphyseal blanch sign on AP.
