🔍 Key Findings
- Double pelvic osteotomy (DPO) reduced angle of lateral opening (ALO) by a median of 11° (p ≤ .001).
- Despite ALO correction, THR reluxation occurred in 5/11 dogs, often within 7 days post-DPO.
- Post-DPO ALO remained elevated (median 56°), with only 2 dogs achieving the recommended 35–45° range.
- Explantation was required in 7/11 dogs (5 aseptic loosenings, 2 infections), suggesting poor long-term implant survival.
- Dogs with luxoid hips were more likely to fail, even with corrected ALO, emphasizing soft tissue instability as a risk factor.
- Compared to TPO (23° correction), DPO yielded a smaller ALO correction, possibly due to older dog population and less elastic pelvis.
- No ventral luxation occurred post-DPO, unlike in TPO studies, likely due to more conservative ALO reduction.
- Authors do not recommend routine DPO for THR luxation due to high complication and failure rates.
