To compare long-term outcomes of juvenile pubic symphysiodesis (JPS) and triple pelvic osteotomy (TPO) in dogs with hip dysplasia.
Prospective clinical trial.
18 dogs with hip dysplasia (ie, distraction index > or = 0.5 in at least 1 hip joint and no, mild, or moderate radiographic evidence of degenerative joint disease [DJD]).
Dogs between 4 and 5.5 months old at enrollment were assigned to undergo JPS, and dogs between 5 and 12 months old were assigned to undergo TPO. All dogs were reexamined at 2 years of age.
At 2 years of age, there were no significant differences between groups in regard to lameness scores, angle of extension of the hip joints, distraction index, peak vertical force, acetabular angle, radiographic DJD score, or owner-assigned scores of clinical function. Dorsal acetabular rim angle was significantly higher in dogs that underwent JPS than in dogs that underwent TPO. For dogs that underwent TPO, dorsal acetabular rim angle was significantly decreased and acetabular angle was significantly increased at 2 years of age, compared with values obtained prior to surgery.
Results suggest that JPS and TPO have similar effects on hip joint conformation in dogs with moderate to severe hip dysplasia but that neither procedure eliminates the hip joint laxity characteristic of hip dysplasia or the progression of degenerative changes.
比较青少年耻骨联合固定术（JPS）和三联骨盆截骨术（TPO）治疗犬髋关节发育不良的长期疗效。
前瞻性临床试验。
18只患有髋关节发育不良的犬（即至少一个髋关节的牵引指数≥0.5，且无、轻度或中度退行性关节病[DJD]的影像学证据）。
入组时4至5.5月龄的犬被分配接受JPS，5至12月龄的犬被分配接受TPO。所有犬在2岁时进行复查。
在2岁时，两组在跛行评分、髋关节伸展角度、牵引指数、垂直峰值力、髋臼角度、影像学DJD评分或主人指定的临床功能评分方面无显著差异。接受JPS的犬的髋臼背侧缘角度显著高于接受TPO的犬。对于接受TPO的犬，与手术前的值相比，2岁时髋臼背侧缘角度显著降低，髋臼角度显著增加。
结果表明，JPS和TPO对中重度髋关节发育不良犬的髋关节形态有相似的影响，但两种手术均不能消除髋关节发育不良特有的髋关节松弛或退行性改变的进展。
