The treatment of periprosthetic fractures.

The management of periprosthetic fractures is an issue of increasing importance for orthopaedic surgeons. Because of the expanding indications for total joint arthroplasty (TJA) and an aging population with increasingly active lifestyles, the incidence of primary and revision TJA is increasing, and there is a corresponding increase in the prevalence of periprosthetic fractures about a TJA. The management of these fractures is often complex because of issues with obtaining fixation around implants, dealing with osteopenic bone or compromised bone stock, and the potential need for revising loose TJA components. In addition, these injuries frequently occur in frail, elderly patients, and the literature has demonstrated that both morbidity and mortality in these patients is similar to that of the geriatric hip fracture population. As such, the early restoration of function and ambulation is critical in patients with these injuries, and effective surgical strategies to achieve these goals are essential.
