Quality of life after primary hemiarthroplasty for femoral neck fracture. 6-year follow-up of 185 patients.

Totally, 185 patients with a mean age of 80 years treated by Austin-Moore cementless hemiarthroplasty for an acute femoral neck fracture were compared with age- and sex-matched nonfracture controls. There were 22 early complications, notably 7 percent dislocation and 4 percent deep infection. Later on, two acetabular protrusions and four loosenings of the prosthesis requiring admission were recorded. Mortality after the fracture was 12 percent above the control level at 3 months, 19 percent at 12 months, and 21 percent at 18 months. The 5-year mortality was about 60 percent in both patients and controls. The average loss of life in the fracture group compared with the control group was 425 days. After a mean follow-up period of 6 years, 24 of the 65 patients still alive and the 49 of the 60 controls were living in their own homes; and 28 of the patients were institutionalized in a hospital unit for chronic care. Half of the patients and most of the controls were able to move about independently. We concluded that Austin-Moore hemiarthroplasty is associated with serious complications that prevent social rehabilitation and function to reach acceptable levels.
