Abstract
Objectives:Hemiarthroplasty (HA) is the current standard of care for displaced femoral neck fractures (FNFs) in non-ambulators. Despite excellent outcomes, arthroplasty-specific risks remain, including dislocation, implant failure, periprosthetic fracture and infection, and fat embolization syndrome. To eliminate the possibility of these complications, should non-ambulatory patients with acute, native hip FNFs be treated with simple hip resection arthroplasty (HRA) instead of HA?Design:Retrospective case series.Setting:Large, urban level-1 trauma center.Patients/Participants:Five non-ambulatory patients (6 hips) with acute, native hip FNF underwent femoral head and neck resection. Also, the most recent 10 FNFs treated with HA were also identified for comparison purposes.Intervention:HRA was performed via a Smith-Peterson approach with an oscillating saw or osteotome to complete the fracture or perform a fresh neck cut.Main Outcome Measurements:Outcomes included postoperative vs preoperative VAS pain scores and narcotics usage, and return to baseline functional status (sit up in bed or a chair postoperatively). Procedure time for HRA was compared with the 10 most recent patients with FNF treated with HA.Results:HRA resulted in decreased postoperative vs preoperative VAS pain scores (7.7 vs 3.3, P = .002), and decreased operative times (59.2 minutes for HRA, 111.8 minutes for HA, P < .001). All HRA patients had immediate return of baseline function.Conclusion:HRA offers shorter operative times when compared with HA, decreased postoperative VAS pain scores, and immediate return to functional baseline status without possibility of arthroplasty-specific complications. HRA may be an acceptable treatment option for FNFs in the non-ambulator.Level of evidence: IV
