Abstract
Dislocations occurring in 3,199 Charnley total hip arthroplasties in t wo orthopaedic centers between 1979 and 1991 performed by either the t ranstrochanteric or posterior approach were studied. The incidence of dislocation within 2 years of surgery (2.8%), as well as the overall f requency (3.4%), did not differ between the two centers. Regardless of approach, there was a higher risk of dislocations for patients with r heumatoid arthritis and nonhealed hip fractures than for patients with osteoarthrosis. A logistic regression analysis, reflecting the differ ences in preoperative hip diagnoses and sex, indicated that the disloc ation rate was not influenced by the surgical approach. More early dis locations were documented after the posterior approach, but without in creases in the rates of recurrence or revision. Arthroplasties perform ed by less experienced surgeons through the posterior approach resulte d in more dislocations.
