AimsThe aim of this study was to compare the functional and radiological outcomes in patients with a displaced fracture of the hip who were treated with a cemented or a cementless femoral stem.Patients And MethodsA four-year follow-up of a randomized controlled study included 141 patients who underwent surgery for a displaced femoral neck fracture. Patients were randomized to receive either a cemented (n = 67) or a cementless (n = 74) stem at hemiarthroplasty (HA; n = 83) or total hip arthroplasty (THA; n = 58).ResultsEarly differences in functional outcome, assessed using the Harris Hip Score, the Short Musculoskeletal Functional Assessment score and EuroQol-5D, with better results in cemented group, deteriorated over time and there were no statistically significant differences at 48 months. Two (3%) patients in the cemented group and five (6.8%) in the cementless group underwent further surgery for a periprosthetic fracture. This difference was statistically significant (p = 0.4). No patient underwent further surgery for instability or infection between one and four years postoperatively. The mortality and the radiological outcomes were similar in both groups.ConclusionPatients with a displaced femoral neck fracture treated with an arthroplasty using a cemented or cementless stem had good function and few complications up to four years postoperatively. However, due to the poor short-term functional outcomes in the cementless group, the findings do not support their routine use in the treatment of these elderly patients.
