Incidence of total hip replacement in Copenhagen
Department of Orthopaedic Surgery, Frederiksberg Hospital, Department of Orthopaedic Surgery Righospitaled, University of Copenhagen (Denmark)
Background. Hip arthroplasty is one of the most common and successful major elective operations. Although the prevalence of coxarthosis has not changed during the last few decades, the total number of arthroplasties has steadily increased. However it has recently been reported that the incidence of hip arthroplasty in Jutland, Denmark increased from 1981 to 1988 but was steady during 1988-1990. The incidence of total hip replacement was studied in Copenhagen during a 17 year period from 1979 to 1995.
Methods. During a period of 17 years (January 1979-December 1995) all patients operated with a total hip replacement at Frederiksberg University Hospital were recorded.
Results. A total of 1761 primary total hip replacements were performed (1369 in women and 392 in men). The mean age was 74 years. The underlying disease among patients who underwent total hip arthroplasty was osteoarthritis in 1174 cases, for fracture sequelae in 355 cases, for primary fracture treatment in 184 cases, in rheumatoid arthritis in 26 cases and various other conditions in 22 cases. The overall incidence was 118/100000 inhabitants/ year. The incidence for the population aged over 50 years was 293/100000. The incidence increased from 63 per 100000 persons in 1979 to 122 per 100000 in 1995 although it was more or less steady between 1990-1995.
Conclusions. The incidence of primary total hip arthroplasty was similar to the incidence found in Sweden and stable during 1990-95.
