🔍 Key Findings

• DPO improved joint congruity and clinical signs in dogs ≥10 months old with minimal osteoarthritis.
• Median Norberg angle increased by 21.8% 1 year postoperatively (from 87° to 106°; p < .01).
• Femoral head coverage increased significantly, with PC rising 66.7% and LHC by 162.5% at 1 year (p < .01).
• No significant change in pelvic canal width postoperatively, suggesting pelvic conformation was preserved.
• All ilial osteotomies healed with complete osseous bridging by 8 weeks; 7/11 pubic osteotomies achieved full healing.
• No intraoperative or postoperative complications were reported, including implant failure.
• Locking plates and additional ventral plating were used in select cases and may have contributed to implant stability.
• DPO may be extended to older dogs with suitable hip morphology and minimal OA, expanding traditional age criteria.
