Arthroplasty with Cement Resulted in Better Functioning Than Arthroplasty without Cement in Older Patients with Displaced Femoral Neck Fracture

Inngul C, Blomfeldt R, Ponzer S, Enocson A. Cemented versus uncemented arthroplasty in patients with a displaced fracture of the femoral neck: a randomised controlled trial. Bone Joint J. 2015 Nov;97-B(11):1475-80. ### Question: In patients >65 years of age with a displaced femoral neck fracture, should a cemented or uncemented femoral stem be used? ### Design: Randomized (allocation concealed), unblinded, controlled trial with 4 and 12 months of follow-up. ### Setting: A large Swedish trauma center. ### Patients: 141 patients >65 years of age (mean age, 81 years; 70% women) who presented within 48 hours after acute displaced fracture of the femoral neck due to low-energy trauma and had total hip arthroplasty (65 to 79 years of age) or hemiarthroplasty (HA) (≥80 years of age). The exclusion criteria were severe cognitive dysfunction, alcohol or drug abuse, rheumatoid arthritis, osteoarthritis, residence in an institution, or inability to walk independently. ### Intervention: Cemented Exeter stem with gentamicin bone cement (n = 67) or uncemented hydroxyapatite Bimetric stem (n …
