🔍 Key Findings
- DPO reduced the angle of lateral opening (ALO) from a median of 66° to 56° (p ≤ .001) and increased the version angle (VA) from 26° to 35° (p ≤ .03).
- Luxation recurred in 5/11 dogs, despite DPO, within a median of 7 days.
- 7/11 dogs eventually required explantation due to aseptic loosening (5) or infection (2), indicating poor long-term outcomes.
- Post-DPO ALO values were still above recommended thresholds (35°–45°) in most cases, and only 2 dogs reached target ALO, both of whom still reluxated.
- DPO was less effective at reducing ALO compared to triple pelvic osteotomy (TPO), likely due to plate design and patient skeletal maturity.
- No ventral luxations occurred, suggesting DPO may avoid cup-stem impingement despite incomplete ALO correction.
- High rates of aseptic loosening may result from initial luxation-induced wear debris or suboptimal cup orientation.
- Authors do not recommend DPO as a routine management strategy for THR luxation due to high complication and explantation rates.
