What is the most common presentation of slipped capital femoral epiphysis (SCFE)?

• A. Pain in the hip joint
• B. Restricted internal rotation of the hip
• C. Prominent knee pain
• D. Flat foot deformity

Answer: (B)

Slipped capital femoral epiphysis (SCFE) typically presents with restricted internal rotation of the hip as one of the most common indicators. This restriction occurs because the femoral head is displaced relative to the neck of the femur due to slippage at the growth plate. As the condition often develops in adolescent patients, the range of motion in the hip is affected, particularly during internal rotation.

Patients may present with varying degrees of hip pain or knee pain, but the hallmark feature that helps identify SCFE is the limitation of internal rotation of the hip when the hip is flexed. This signifies that the structural integrity and alignment of the femoral head and neck are compromised. Observing this specific limitation can aid clinicians in making a prompt diagnosis, which is critical in preventing further complications associated with this condition.

While hip joint pain and knee pain can occur, they are not as definitive or characteristic as the restricted internal rotation. Furthermore, a flat foot deformity is not typically associated with SCFE and would not be a common presentation in this scenario.
