medium · MCQ · Q-83CA37
A 12-year-old obese boy presents with a 3-week history of a dull, aching left hip pain radiating to the knee, with no history of trauma. He walks with an antalgic, externally rotated gait. On examination, passive flexion of the left hip automatically results in external rotation. What is the most definitive diagnostic view to confirm the diagnosis on plain radiography?
- A.Anteroposterior view of the pelvis in internal rotation
- B.Cleaves (frog-leg lateral) view of both hipsCorrect answer
- C.Lauenstein view in maximum abduction
- D.False-profile view of Lequesne
Solution
The patient has a slipped capital femoral epiphysis (SCFE), classically seen in adolescent, obese males. While an AP pelvis view may show Klein's line abnormality or widening of the physis, the frog-leg lateral view (Cleaves view) is the most sensitive diagnostic view to demonstrate the early posterior and inferior displacement of the femoral head.
