Transepiphyseal fractures of the neck of the femur in very young children.

Five severely displaced transepiphyseal fractures of the neck of the femur in five very young children were treated nonoperatively with a spica cast. Four of these fractures healed in varus, but two with an open proximal femoral physis corrected with growth. One fracture had an 18-month delay in diagnosis and treatment, but subsequently healed after a valgus osteotomy of the proximal femur and bone grafting. There was no case of avascular necrosis. We recommend initial nonoperative treatment with hip spica cast immobilization for this type of fracture in the very young child. If correction of residual coxa vara or limb length discrepancy is indicated, it may be done later.
