| Abstract: | The ability of two canine pelvic osteotomy techniques to provide lateral rotation of the acetabulum was compared in vitro using an instrumented spatial linkage to measure acetabular displacement. Technique 1 was a double osteotomy and technique 2 was a triple osteotomy. We demonstrated that technique 1 provided more lateral rotation of the acetabulum. Both techniques provided a large amount of acetabular an-teversion. No relationship could be found between pelvic morphometry and final acetabular position. We concluded that the surgeon is the primary factor controlling final acetabular position. |
