Slipped Capital Femoral Epiphysis Associated With Vitamin C Deficiency in a 7-year-old Boy.

Scurvy is rare in the present world and is mostly found in children with abnormal dietary habits and physical and mental disabilities. Scurvy can present in various forms, mimicking several common diseases, thus making the diagnosis difficult. Spontaneous epiphyseal separation is known to occur in scurvy, although rarely reported. The usual locations of these epiphyseal separations are distal femur and proximal humerus. Our case is unique in that scurvy in a seemingly normal child resulted in proximal femur epiphyseal separation which was not reported previously. We report a case of a 7-year-old boy presenting with pain and swelling in multiple joints for 6 months and later inability to walk. Pseudoparalytic frog-leg posture, dietary history of selective eating, and typical radiologic features made us consider a diagnosis of scurvy which was confirmed by a low serum vitamin C level. He developed epiphyseal separation of proximal femur and was treated with percutaneous screw fixation. Vitamin C supplementation resulted in prompt improvement clinically and radiologically.
