The aim of this study was to describe the technique and the clinical outcome of cats with obstipation as a result of pelvic canal narrowing, treated using an alternative triple pelvic osteotomy technique.
Five cats with obstipation as a result of pelvic canal narrowing due to pelvic fracture malunion or secondary hyperparathyroidism were treated by triple pelvic osteotomy. After performing the iliac osteotomy and medial partial cortical debridement (4/5 cases), the pelvic canal was widened by moving the caudal fragment of the ilium to the lateral aspect of the cranial fragment. The iliac fragments were fixed by a 2.7-mm lag screw (5/5 cases) and an additional 2 Kirschner wires 0.8 mm (1/5 cases).
The radiographic examination immediately postoperatively and 8 weeks postoperatively showed a mean pelvic canal enlargement of 20% (range 7-38%). Minor complication occurred in one case; this resolved 15 days postoperatively without any treatment. Complications and recurrence of obstipation did not occur during the final follow-up, ranging between 5 months and 1 year in any of these cases.
The use of lag screw fixed triple pelvic osteotomy resulted in widening of the pelvic canal and led to a satisfactory outcome with no major complications. This technique is fast, requires no expensive implants and it is relatively straightforward. Further cases are required to determine the success and complication risk of the procedure.
本研究旨在描述因骨盆管狭窄导致便秘的猫采用替代三联骨盆切开术治疗的技术和临床效果。
5 只因骨盆骨折畸形愈合或继发性甲状旁腺功能亢进导致骨盆管狭窄而发生便秘的猫采用三联骨盆切开术进行治疗。完成髂骨切开术和内侧部分皮质清创术（4/5 例）后，通过将髂骨尾段向颅段外侧移动来扩大骨盆管。用 2.7mm 的拉力螺钉（5/5 例）和另外 2 根 0.8mm 的克氏针（1/5 例）固定髂骨片段。
术后即刻和 8 周的影像学检查显示骨盆管平均扩大 20%（范围 7-38%）。1 例出现轻微并发症，术后 15 天无需治疗即可缓解。在最后一次随访中，没有发生任何并发症或便秘复发，这些病例的随访时间在 5 个月至 1 年之间。
使用拉力螺钉固定三联骨盆切开术可扩大骨盆管，并取得了令人满意的效果，无重大并发症。该技术快速、无需昂贵的植入物，且相对简单。需要进一步的病例来确定该手术的成功率和并发症风险。
