🔍 Key Findings
- DPO significantly improved femoral head coverage, increasing mean DLS from 36.1% to 71.4% postoperatively (p < 0.001).
- No significant change in DLS between immediate postoperative and follow-up scans, suggesting stable surgical outcomes over time.
- Greater plate angle (30°) yielded larger DLS improvement (mean increase: 39.8%) compared to 25° and 20° plates.
- Only 3 hips had post-op DLS scores <55%, indicating most patients had lower risk of osteoarthritis progression.
- No correlation found between DLS improvement and age, body weight, or side of surgery, suggesting broad applicability.
- CT was used for DLS measurement in simulated weight-bearing, improving precision over radiographic methods.
- Major limitations included small sample size, multiple surgeons, and variable sedation vs anesthesia during imaging.
- DPO confirmed as effective for reducing dorsolateral subluxation, improving coxofemoral joint congruency in dysplastic dogs.
