Summary: Anatomically precontoured locking plates have revolutionized the care of many fractures, including those of the proximal humerus, distal radius, distal femur, and proximal tibia. Locking plates designed for the proximal femur have recently been introduced and offer a potential means to deal with complex fractures of this region as well. The purpose of this article is to describe the indications for the use of locking plates in subtrochanteric and other complex fractures of the proximal femur, and to provide a detailed description of the surgical technique.
