title: Postoperative dislocation in the Charnley and Brunswik total hip arthroplasty.
abstract: An analysis of 351 total hip arthroplasties according to the method and design of Charnley and 194 Brunswik snap-fit deepened socket design failed to show any significant difference in the incidence of dislocation. Neither were the angulation of the acetabular prosthesis in the anteroposterior projection, time after operation, experience of the surgeon and displacement of the greater trochanter significantly related to dislocation. The variables of significance were anatomical superior-inferior position of the acetabular prosthesis and possibly the number of previous operations on the hip joint.
