Function after primary hemiarthroplasty and secondary total hip arthroplasty in femoral neck fracture.

Abstract

Four to 12 years after primary treatment of femoral neck fracture with hemiarthroplasty in a group of Finnish patients and secondary total hip arthroplasty as a salvage procedure for healing complication after primary osteosynthesis in a group of Swedish patients, function was classified and the Nottingham Health Profile questionnaire was applied. The two groups were comparable with regard to age, sex, and social status. The patients with secondary total hip arthroplasty used walking aids to a lesser extent than the patients with hemiarthroplasty and experienced less problems in several aspects of life. Walking ability was considered unchanged, compared to prefracture, to a larger extent in the secondary total hip arthroplasty group. Thus, secondary total hip arthroplasty in patients with healing complication following primary osteosynthesis gives better long-term functional capacity than that obtained with a primary hemiarthroplasty.
