Triple Pelvic Osteotomy and Double Pelvic Osteotomy

Vet Clin North Am Small Anim Pract. 2017 Jul;47(4):865-884. doi: 10.1016/j.cvsm.2017.02.005. Epub 2017 Apr 28.


Triple and double pelvic osteotomy (TPO, DPO) are performed with the goal of increasing acetabular ventro-version, increasing femoral head coverage, and decreasing femoral head subluxation. Since the first descriptions of TPO, there have been modifications in technique, most notably omission of the ischial osteotomy for DPO, and improvements in the implants, including availability of locking TPO/DPO bone plates. Associated complication rates seem to have declined accordingly. The most salient questions regarding these procedures remain what selection criteria should be used to identify candidates and whether halting or preventing osteoarthritis is necessary to consider these surgeries clinically beneficial.
