Abstract
Introduction
There remains disagreement about the use of cemented or uncemented total hip arthroplasty (THA) for patients with a displaced intracapsular femoral neck fracture (FNF). The aim of this study was to assess implant survival, mortality, and postoperative complication rates of uncemented THA for a displaced intracapsular FNF in a single center.
Patients and methods
A cohort of 115 patients who received uncemented THAs for a displaced intracapsular FNF was retrospectively examined for implant survival in terms of revision and any reoperation, mortality, and postoperative complications.
Results
The one- and five-year implant survival was 99.1% (95% confidence interval (CI) 97.3–100.9) and 97.8% (95% CI 94.7–100.9) for revision and 93.6% (95% CI 88.9–98.3) and 90.0% (95% CI 83.3–96.7) for any reoperation, respectively. Impaired mobility was significantly associated with lower implant survival (p = 0.01). The one, three, and 12 month mortality rates were 2.8% (95% CI 0–5.9), 3.7% (95% CI 0.2–7.2), and 5.6% (95% CI 1.3–9.9), respectively. Postoperative complication rate was 10% with 5% intra-operative fractures.
Conclusions
Contrary to earlier reports of results of uncemented THA for displaced FNF, the results of this study were comparable with those reported in the literature for cemented THA in displaced FNF with respect to implant survival, mortality, and complication rates. This indicates that uncemented THA could be a viable option for these patients. In future, the additional literature with a prospective design is needed to support and reinforce our conclusion.
