Abstract: | BackgroundTreatment options for metastatic osseous lesions of the proximal femur include hemiarthroplasty (HA) or total hip arthroplasty (THA) depending on lesion characteristics and patient demographics. Studies assessing short-term outcomes after HA/THA in this patient population are limited. Therefore, the purpose of this present study was to identify short-term rates of morbidity and mortality after HA/THA for pathological proximal femur fractures, as well as readmission and reoperation rates and reasons.MethodsThis study utilized a large, prospectively collected registry to identify patients who underwent HA/THA between 2011 and 2018. Patients were stratified by indication for surgery, including pathological fracture, nonpathological fracture, and osteoarthritis. Baseline patient characteristics and postoperative complications were compared using bivariate and/or multivariate analysis.ResultsIn total, 883 patients undergoing HA/THA for a pathological fracture were identified. Relative to an osteoarthritis cohort, these patients tended to be older, had a lower body mass index, and had significantly more preoperative comorbidities. These patients had high rates of total complications (13.93%), including thirty-day mortality (3.29%), unplanned return to the operating room (4.98%), and pulmonary complications (3.85%). Patients with pathological fracture had a longer operative duration relative to osteoarthritis and nonpathological cohorts (+27 and +25 minutes, respectively), despite having high rates of HAs performed.ConclusionPatients undergoing hip arthroplasty for pathologic proximal femur fracture have increased morbidity and mortality relative to an osteoarthritis cohort. However, patients with a pathological fracture have similar rates of morbidity and mortality when compared with a nonpathological fracture cohort, but did experience higher rates of perioperative blood transfusion and unplanned readmissions.Level of EvidenceIII. |
