A 16-year-old boy presented with bilateral groin pain and limp (R > L) for 3 months. He was obese (BMI:31.4) with features of hypogonadism (Fig. 1). Right hip had fixed external rotation deformity and movements were restricted. Plain radiographs revealed bilateral Slipped Capital Upper Femoral Epiphysis (SCUFE): Grade III on right and Grade I on left side (Fig. 2). Serum Vitamin D level was low (12 ng/ml). He was treated by in situ fixation of the slippage of both hips, by 2 cancellous screws (Fig. 3) followed by immediate relief of pain.
