[The treatment concept and results of peri-/sub-prosthetic fractures]

The treatment of choice in ipsilateral femoral shaft fractures in patients with hip prosthesis depends on the location of the fracture lines and the observation of loosening of the prosthesis. Either a change of prosthesis, if necessary in combination with refixation of the greater trochanter or simple open reduction with internal fixation (ASIF) along with autologous and/or homologus spongiosa are the used techniques. The rate of complications in peri- or subprothetic fractures is high. Lack of motion in hip and knee joint occurs frequently.
