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.
