Salter-Harris type-IV displaced distal radius fracture in a 5-year-old.

Displaced Salter-Harris type-IV fractures are rare in young children and can result in articular incongruity or premature physeal arrest. We describe a 5-year-old boy who sustained a displaced left distal radial Salter-Harris type-IV fracture. The patient had normal wrist function and physeal growth at the 3-year postoperative follow-up. Our patient is by far the youngest reported child with a displaced Salter-Harris type-IV fracture of the distal radius. Prompt anatomic reduction and fixation of a displaced distal radial Salter-Harris type-IV fracture can result in excellent short-term wrist motion with maintenance of physeal function.

Linear morphea and leg length discrepancy: treatment with a leg-lengthening procedure.

A 15-year-old Colombian boy with a 10-year history of linear morphea presented to a pediatric orthopedic clinic with a leg length discrepancy. The morphea had been previously treated with methotrexate, oral and topical steroids, and topical vitamin D, but the lesion persisted, extending down the entire medial aspect of the left leg across the popliteal fossa. The patient had atrophy and growth retardation of the left leg, resulting in lower extremity bone and joint pain and a 3-cm limb length disparity at maturity. The patient preferred left tibial lengthening to improve the limb length disparity.
