To evaluate feasibility of single-session bilateral triple pelvic osteotomy with 8-hole iliac bone plates in dogs with bilateral hip dysplasia.
Retrospective study.
95 dogs with bilateral hip dysplasia.
Medical records were reviewed, and information was obtained on signalment; body weight; angles of subluxation and reduction prior to surgery; durations of surgery and hospitalization; postoperative mobility; severity of lameness, radiographic grade of hip dysplasia, Norberg angle, and femoral head coverage before and after surgery; time required for radiographic evidence of iliac healing; change in pelvic diameter; implant integrity; and complications.
Mean age at the time of surgery was 10.8 months, and mean weight was 35.2 kg (77.4 lb). Prior to surgery, mean angles of subluxation were 2.2 degrees on the right and 2.6 degrees on the left; mean angles of reduction were 25.9 degrees on the right and 27.3 degrees on the left. Mean surgical time was 95 minutes. All but 1 dog were able to walk on their own by the fourth day after surgery. Mean hospitalization time was 7.5 days. Clinical signs of lameness and radiographic grade of hip dysplasia were significantly improved during follow-up examinations. Mean time for radiographic iliac healing was 8 weeks. None of the plates and only 7 of the 1,520 (0.5%) screws loosened after surgery. Nineteen dogs had complications, but all complications were minor.
Results suggest that single-session bilateral triple pelvic osteotomy with 8-hole iliac bone plates is effective for treatment of dogs with bilateral hip dysplasia.
评估采用8孔髂骨板进行单期双侧三联骨盆截骨术治疗双侧髋关节发育不良犬的可行性。
回顾性研究。
95只双侧髋关节发育不良的犬。
查阅病历，获取以下信息：信号特征；体重；术前半脱位和复位角度；手术和住院时间；术后活动能力；跛行严重程度、髋关节发育不良的放射学分级、诺伯格角以及术前和术后股骨头覆盖情况；髂骨愈合的放射学证据所需时间；骨盆直径变化；植入物完整性；以及并发症。
手术时的平均年龄为10.8个月，平均体重为35.2千克（77.4磅）。术前，右侧半脱位平均角度为2.2度，左侧为2.6度；右侧复位平均角度为25.9度，左侧为27.3度。平均手术时间为95分钟。除1只犬外，所有犬在术后第4天就能自行行走。平均住院时间为7.5天。在随访检查期间，跛行的临床症状和髋关节发育不良的放射学分级均有显著改善。髂骨放射学愈合的平均时间为8周。术后，没有一块钢板松动，1520颗螺钉中只有7颗（0.5%）松动。19只犬出现并发症，但所有并发症均为轻微并发症。
结果表明，采用8孔髂骨板进行单期双侧三联骨盆截骨术治疗双侧髋关节发育不良犬是有效的。
