Cemented versus uncemented hemiarthroplasty of hip for displaced neck of femur fractures: A prospective comparative study

Abstract

Objective: To prospectively compare the functional outcome associated with cemented and uncemented hemiarthroplasty of the hip. Patients: All individuals designated for hemiarthroplasty, older than 55 years, with a displaced femoral neck fracture and the ability to walk prior to injury (48 patients) presented with a displaced femoral neck fracture. Materials and Methods: Hip hemiarthroplasty with a cemented femoral component or an uncemented component is done. Observations: Harris Hip Score was used to objectively measure functional outcomes. Results: No statistically significant differences were present in the groups’ preoperative or intraoperative characteristics, like ASA grade, operative time, anesthesia time, estimated blood loss. No difference was found in haemoglobin level or acute complication rate postoperatively. At 30-day, 60-day, and 1-year follow-ups, no clinically or statistically significant differences were found in mortality, complication rate including infections, and change in Daly. Conclusions: In treating femoral neck fractures, cemented and uncemented femoral components are associated with similar functional outcomes at 1 year. Neither of the treatment modalities has a statistically significant advantage over the other. Either can be chosen according to the surgeon’s preference, implant availability and affordability, and familiarity with the technique.
