Perioperative Mortality After Cemented or Uncemented Hemiarthroplasty for Displaced Femoral Neck Fractures—A Systematic Review and Meta-analysis

Fenelon, Christopher et al.


Debate surrounds the use of cemented or uncemented prostheses for the treatment of displaced femoral neck fractures (FNF). Many guidelines recommend the use of the cemented hemiarthroplasty (CHA). Proponents of CHA point out the increased re-operation rate while proponents of uncemented hemiarthroplasty (HA) highlight the increased mortality rate in the perioperative period. The aim of this study was to systematically review the literature to evaluate perioperative mortality after HA for displaced FNFs.


A systematic review and meta-analysis was performed of MEDLINE, Cochrane Library, and Embase databases evaluating perioperative mortality after HA for displaced FNFs. Randomized control trials and observational studies were included comparing current-generation stem designs. A meta-analysis was performed on studies that directly compared the different modes of fixation.


Twenty-two studies were included (seven randomized control trials and 15 observational studies), with a total of 183,167 HAs for treatment of a displaced FNF. Fourteen studies were included in the meta-analysis. There was a higher cumulative odds of death within the first 48 hours in those with CHA compared with uncemented HA (OR: 1.64; 95% CI: 1.35, 2.00; P ≤ .01). No difference was found in mortality at 7 days, 30 days, and one year.


CHA is associated with an increased mortality rate within the first two days of surgery with no difference at 7 days, 30 days, and one year. Surgeons should consider tailoring their stem choice based on the physiological status of the patient when planning HA for FNFs. Techniques to reduce the risk of bone cement implantation syndrome should be used.
