• W2329953702 abstract "Background Traditional treatments for pathological fractures of the proximal femur resulting from metastatic bone disease include fixation with intramedullary nailing supplemented with polymethylmethacrylate, osteosynthesis with a plate-screw construct and polymethylmethacrylate, or endoprosthetic reconstruction. Despite the frequent practice of these treatments, treatment outcomes have not been rigorously compared. In addition, very few studies examine specific approaches to endoprosthetic reconstruction such as long stem hemiarthroplasty. Questions/purposes This study examines survival, functional outcomes, and complications associated with long stem hemiarthroplasty in a small group of patients treated for impending and actual pathologic fractures of the proximal femur resulting from metastatic bone disease. Methods Between 2012 and 2015, 21 patients were treated with long stem cemented hemiarthroplasty in 22 limbs. During that time, indications for this approach included lesions from metastases, myeloma, or lymphoma involving the proximal femur that resulted in an impending or actual pathological fracture. An impending fracture was classified as a painful lesion with at least 50% cortical erosion. During the study period, six patients with proximal femoral metastases not deemed to meet these indications were treated with other surgical approaches such as intramedullary nailing supplemented with polymethylmethacrylate and osteosynthesis with a plate-screw construct and polymethylmethacrylate. Mortality was tracked through medical records and phone calls to the patients and their families. Followup for the entire group of patients (n = 22) ranged from 1 to 27 months with a mean duration of 11 months. For patients with at least 1 year of followup (n = 11), the mean duration was 18 months (range, 12-27 months) and for patients with less than 1 year of followup (n = 11), the mean duration was 3 months (range, 1-11 months). Functional outcomes were evaluated according to the Musculoskeletal Tumor Society (MSTS) scoring system for lower extremities, the Eastern Cooperative Oncology Group (ECOG) Scale of Performance Status, and the Karnofsky Performance Scale (KPS) Index. Scores and complications were determined by direct patient examination, retrospective chart review, review of a longitudinally maintained institutional database, and followup phone calls. Results Ten patients died of disease within the followup period. Before surgery, the median total MSTS score for the entire group of patients (n = 22) was 4.5 (range, 0-23), the median ECOG score was 3.5 (range, 1-4), and the median KPS score was 40 (range, 30-70). Postoperatively, the median total MSTS score (measured at most recent followup) for the entire group of patients was 21 (range, 5-30), the median ECOG score was 2 (range, 0-3, 68% ≤ 2), and the median KPS score was 60 (range, 40-100). For the 11 patients with at least 1 year of followup, the median total MSTS score (measured at most recent followup) was 27 (range, 21-30), the median ECOG score was 1 (range, 0-2, 100% ≤ 2), and the median KPS score was 80 (range, 60-100). For the remaining 11 patients with less than 1 year of followup, the median total MSTS score (measured at most recent followup) was 11 (range, 5-25), the median ECOG score was 3 (range, 1-3, 36% ≤ 2), and the median KPS score was 40 (range, 40-80). Complications included one periprosthetic fracture resulting from a fall, three cases of radiation-induced edema, and two cases of sciatica that developed unrelated to the procedure. Conclusions Long stem cemented hemiarthroplasty results in fair levels of function in a complex population of patients whose prognosis is sometimes measured only in months and who otherwise might be disabled by their metastatic lesions. Comparative trials applying consistent indications and inclusion criteria should be performed between this approach and fixation with intramedullary nailing supplemented with polymethylmethacrylate as well as osteosynthesis with a plate-screw construct and polymethylmethacrylate.
