Hemiarthroplasty and Total Hip Arthroplasty in the Treatment
As treatment options for displaced osteoporotic femoral neck fractures, hemiarthroplasty (HA) and total hip arthroplasty (THA) have been actively addressed. The goal of this study was to compare the results, complications, and perioperative survival of HA and THA in the treatment of pathologic femoral neck fractures caused by neoplastic origin.

A multicenter retrospective cohort study identified patients with pathologic femoral neck fractures treated with HA or THA. The primary outcome was reoperation. Secondary outcomes included 90-day mortality, estimated blood loss (EBL), length of stay (LOS), periprosthetic fracture, periprosthetic joint infection (PJI), and Eastern Cooperative Oncology Group (ECOG) performance status.

--There were 116 HA patients and 48 THA patients, with no differences between groups with regard to ASA, CCI, or Dorr classification.

--There were no differences between HA and THA in the primary outcome of reoperation (5.2% vs 4.2%), or secondary outcomes of perioperative 90-day overall mortality (30.2% vs 25.0%), EBL, transfusion rates, LOS, discharge location, PJI, periprosthetic fracture, or preoperative or postoperative ECOG performance status.

Both HA and THA are feasible therapeutic alternatives for patients with pathologic femoral neck fractures, with no differences in reoperations, morbidity, perioperative 90-day mortality, or functional outcome ratings.
