Quiz Question

In Lomas 2025 et al., on DPO and dorsolateral subluxation, what percentage of hips had a post-DPO DLS score <55%, indicating higher OA risk?

Correct. Only 5 of 45 hips had a post-op DLS <55%, suggesting the majority were low risk for OA development.

Incorrect. The correct answer is 11%.
Only 5 of 45 hips had a post-op DLS <55%, suggesting the majority were low risk for OA development.

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.
