Abstract

Periprosthetic fractures after massive endoprosthetic reconstructions pose a reconstructive challenge and jeopardize limb preservation. Compressive osseointegration technology offers the promise of relative ease of prosthetic revision, since fixation is achieved by means of a short intramedullary device. We retrospectively reviewed the charts of 221 patients who had Compress ® devices implanted in two centers between December, 1996 and December, 2008. The mean followup was 50 months (range, 1-123 months). Six patients (2.7%) sustained periprosthetic fractures and eight (3.6%) had nonperiprosthetic ipsilateral limb fractures occurring from 4 to 79 months postoperatively. All periprosthetic fractures occurred in patients with distal femoral implants (6/154, 3.9%). Surgery was performed in all six patients with periprosthetic femur fractures and for one with a nonperiprosthetic patellar fracture. The osseointegrated interface was radiographically stable in all 14 cases. All six patients with periprosthetic fracture underwent limb salvage procedures. Five patients had prosthetic revision; one patient who had internal fixation of the fracture ultimately underwent amputation for persistent infection. Periprosthetic fractures involving Compress ® fixation occur infrequently and most can be treated successfully with further surgery. When implant revision is needed, the bone preserved by virtue of using a shorter intramedullary Compress ® device as compared to conventional stems, allows for less complex surgery, making limb preservation more likely. Level of Evidence: Level IV, therapeutic study. See Guidelines for Authors for a complete description of levels of evidence.
