Abstract
During the years 1981–1982, 1,729 hip replacements were performed in the population of 943,000 persons in the nine southernmost orthopedic districts of Sweden. This is equivalent to 7,600 hip replacements per annum in the 8.3 million Swedish population. Based on the highest annual district incidence, the national equivalent increases to 12,500. Arthrosis accounted for 57 per cent of the arthroplasties, hip fracture for 23 per cent, and failed total hip replacement for 10 per cent.
