HEALTH Trial: Total Hip Arthroplasty or Hemiarthroplasty for Hip Fracture

The HEALTH trial was a prospective surgical randomized trial that aimed to assess the efficacy of total hip arthroplasty as compared with hemiarthroplasty in patients who had a displaced femoral neck fracture. Total hip arthroplasty is the replacement of both femoral head and acetabulum while hemiarthroplasty only includes replacing the femoral head with the prosthesis. 1495 patients of 50 years of age or older and who had a displaced femoral neck fracture and had been able to ambulate without the assistance of another person before the fracture occurred were included in the study. The primary outcome of the study was the incidence of secondary hip procedure within 24 months of follow-up. It was found to be no different in both groups (P=0.79). The authors concluded that among patients with displaced femoral neck fractures, the incidence of secondary procedures did not differ significantly between patients who were randomly assigned to undergo total hip arthroplasty and those who were assigned to undergo hemiarthroplasty, and total hip arthroplasty provided a clinically unimportant improvement over hemiarthroplasty in function and quality of life over 24 months.
