Where is the femoral head typically positioned in chronic slipped capital femoral epiphysis?

• A. Superior/anterior
• B. Posterior/inferior
• C. Lateral
• D. Medial

Answer: (B)

In chronic slipped capital femoral epiphysis, the femoral head typically shifts to a posterior and inferior position relative to its normal anatomical location. This condition occurs when there is a displacement of the femoral head due to slippage at the growth plate (physis) during periods of growth. The epiphyseal displacement leads to a reduction in the congruence of the hip joint and often results in changes to the biomechanics of the hip.

The characteristic positioning of the femoral head in this condition can be attributed to the altered growth dynamics and stresses across the hip joint. The posterior and inferior displacement can lead to hip pain, limited range of motion, and changes in gait. Understanding this positioning is crucial for diagnosing and managing this condition effectively, as it impacts treatment decisions and potential surgical interventions.
