Use of Cortical Strut Allograft in Periprosthetic Femur Fractures

Abstract

The number of periprosthetic fractures in patients with orthopaedic implants is increasing. Surgeons need a variety of techniques to manage such fractures and a potentially unstable implant. Strut grafts of cortical bone are useful in treating periprosthetic fractures of the femur. Plate fixation with screws and cables or wires is also used, as is revision of the prosthesis if required, depending upon the location of the fracture and stability of the implant. Because of this, orthopaedic surgeons need to be familiar with indications for the use of allograft bone as well as with its biomechanics and biology. The treatment of periprosthetic fractures requires a multidisciplinary approach and a careful preoperative surgical plan. With this, and with the other requirements named here, studies have found consistently good results in the management of periprosthetic fractures, with a reduced incidence of nonunion in most series of patients.
