Imaging in a 14-year-old male patient with a sudden onset of right hip pain, a) and b) radiographs at presentation, showing a Shepherd deformity and pathological fracture of the proximal femur, c) an axial CT scan showing the fracture, d) a bone scan, used to rule out polyostotic fibrous dysplasia, showing that it was confined to the right proximal femur, e) after proximal femoral osteotomy to correct the deformity and fixation with intramedullary nail, and f) at two months post-operatively showing healing of the fracture and osteotomies, at which point the patient had no pain.
