To assess the medium- to long-term radiographically confirmed outcomes in juvenile dogs with hip dysplasia (HD) that did and did not undergo double pelvic osteotomy (DPO).
Retrospective case-controlled.
Twenty-six dogs with HD that were candidates for DPO; 22 dogs underwent DPO (16 bilateral, six unilateral); four dogs did not.
Initial and follow-up radiographs of DPO candidates (2011-2017) that did and did not undergo surgery were reviewed, and the British Veterinary Association and Kennel Club Hip Dysplasia Scheme score (BVA-HD), osteoarthritis score (OAS) and laxity index score (LI) were determined. Baseline and follow-up BVA-HD, OAS, and change in radiographically confirmed scores were compared by using analysis of variance for correlated samples.
There was no significant difference in BVA-HD or OAS between surgically treated and nonsurgically treated cohorts at baseline. Follow-up radiographs (median, 49 months) revealed that most (34/38) hips had a BVA-HD ≤10 after DPO, while four of eight hips from the nonsurgical cohort had BVA-HD >10. Follow-up BVA-HD and OAS were lower in hips after surgery (BVA-HD median 2.15, interquartile range [Q1-Q3] 1.3-4.1; OAS median 1.9, Q1-Q3 1.1-4.1) compared with the nonsurgically treated cohort (BVA-HD median 11.4, Q1-Q3 8.1-17.5, P < .01; OAS median 7.0, Q1-Q3 5.1-13.4, P < .01). Seven hips with an LI >1 had no radiographically confirmed progression of osteoarthritis after DPO.
Double pelvic osteotomy prevented radiographically confirmed progression of osteoarthritis in the medium- to long-term. Laxity index score > 1 was not a contraindication for DPO in this study.
Double pelvic osteotomy prevents progression of radiographically confirmed features of osteoarthritis in juvenile dogs with HD.
评估接受和未接受双骨盆截骨术（DPO）的患有髋关节发育不良（HD）的幼年犬的中长期影像学确诊结果。
回顾性病例对照研究。
26只患有HD且适合进行DPO的犬；22只犬接受了DPO（16只双侧，6只单侧）；4只犬未接受。
回顾了2011年至2017年期间适合进行DPO且接受和未接受手术的犬的初始和随访X光片，并确定了英国兽医协会和养犬俱乐部髋关节发育不良评估系统评分（BVA-HD）、骨关节炎评分（OAS）和松弛指数评分（LI）。使用相关样本的方差分析比较基线和随访时的BVA-HD、OAS以及影像学确诊评分的变化。
在基线时，手术治疗组和非手术治疗组之间的BVA-HD或OAS没有显著差异。随访X光片（中位时间为49个月）显示，大多数（34/38）髋关节在DPO后BVA-HD≤10，而非手术组的8个髋关节中有4个BVA-HD>10。与非手术治疗组相比，手术后髋关节的随访BVA-HD和OAS较低（BVA-HD中位值2.15，四分位间距[Q1-Q3] 1.3-4.1；OAS中位值1.9，Q1-Q3 1.1-4.1）（BVA-HD中位值11.4，Q1-Q3 8.1-17.5，P<.01；OAS中位值7.0，Q1-Q3 5.1-13.4，P<.01）。7个LI>1的髋关节在DPO后没有影像学确诊的骨关节炎进展。
双骨盆截骨术在中长期可预防影像学确诊的骨关节炎进展。在本研究中，松弛指数评分>1并非DPO的禁忌证。
