Systematic review of cemented and uncemented hemiarthroplasty outcomes for femoral neck fractures.
Although hemiarthroplasties are an important treatment for femoral neck fractures, the literature does not provide a clear approach for selecting the implant fixation method. Therefore, we performed a systematic search of the medical literature and identified 11 prospective and retrospective studies that compared results between cemented and uncemented femoral implant fixation methods. After independent blind data extraction, we compared variables between cemented and uncemented cohorts using two different meta-analysis models. Pooled data represented 1632 cemented and 981 uncemented hemiarthroplasties (average age of patients, 78.9 and 77.5 years, respectively). The average operating room times and blood loss volumes were 95 minutes and 467 mL, respectively, for the cemented and 80 minutes and 338 mL for the uncemented cohorts. Postoperative mortality rates, overall complications, and pain were similar between the two cohorts. Despite a few potential trends, we found few statistical differences between cemented and uncemented techniques based on reported outcome measurements. In addition, inspection of this literature underscored the lack of and need for consistent and standardized reporting of outcome variables regarding these procedures.
