Abstract
In the management of metastatic tumors causing proximal femoral pathological fractures, proximal femoral endoprosthetic replacements, particularly modular prostheses, are commonly employed to address varied reconstructive needs. This retrospective study evaluated 100 consecutive patients with metastatic proximal femur tumors who underwent reconstruction with modular tumor prosthetics using the METS system between 2001 and 2007. Clinical and functional outcomes were assessed, including overall survival, local control, implant survival, and complications related to patients, tumors, and treatments. The cohort, comprising 45 males and 55 females with a mean age of 60.2 years, primarily underwent the procedure for metastatic cancer management. Seventy-five patients presented with pathological fractures or failed fixed fractures, while 25 were at high risk for fractures. The mean follow-up duration was 15.9 months, ranging from 0 to 77 months. A significant portion of patients (69 out of 100) passed away post-surgery, with most implanted prostheses serving as definitive treatment options until the patients' demise. Complications included dislocation in a minority of cases with unipolar femoral heads and total hip replacements, along with six cases of deep infections. Kaplan-Meier analysis estimated a five-year implant survival rate of 83.1%, with satisfactory functionality observed in 64% of patients based on functional tests. The study underscores the effectiveness of METS modular tumor prostheses in providing long-term functionality with minimal implant-related complications
