In Vitro Analysis of Two Canine Pelvic Osteotomy Techniques

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.
