Avoiding malunion with 95degrees fixed-angle distal femoral implants.
Malunion of the distal end segment of a fractured femur is a common complication after open reduction and internal fixation when using 95degrees fixed-angle devices. Incorrect positioning of the alignment Kirschner wires can result in implant malposition and subsequent malunion. This article discusses the relevant distal femoral anatomy and the technical points necessary to avoid a malunion when using 95degrees fixed-angle devices.
