Background: For transfemoral amputations, the residual femoral length is critically important to prosthetic function. The aim of this report is to describe a novel method of extending femoral length and to assess its stability over time.
Case Description and Methods: A 57-year-old woman with recurrent parosteal osteosarcoma was treated with above-knee amputation. A portion of the distal femoral endoprosthesis, which included uncemented fixation with a Compress((R)) stem, was retained in an effort to extend the short femoral remnant and maximize stump length.
Findings: At 3 years follow-up, the Compress stem remained well-fixed, and there was no soft tissue breakdown over the implant. The patient ambulated with a prosthetic limb and no external support.
Outcomes and Conclusion: To the best of our knowledge, this is the first report of using the Compress device as a means to maintain stable fixation and extend residual femoral length following above-knee amputation.
