Abstract

Objective 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.

Methods 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).

Results 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.

Clinical Significance 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.

三重骨盆截骨术用滞后螺钉固定治疗五只猫的骨盆管狭窄。

摘要

目的 本研究的目的是描述使用替代性三重骨盆截骨术治疗的猫由于盆腔狭窄而致便秘的技术和临床结果。

方法对 5只因盆腔骨折畸形畸形或继发性甲状旁腺功能亢进引起的盆腔狭窄而出现便秘的猫进行三例盆腔截骨术。进行the骨截骨术和内侧部分皮质清创术（4/5例）后，通过将i骨的fragment骨碎片移至颅骨碎片的外侧，扩大了骨盆管。a骨碎片通过一个2.7毫米的拉力螺丝钉（5/5例）和另外2根0.8毫米的Kirschner线固定（1/5例）。

结果 术后立即和术后8周的影像学检查显示，平均骨盆管增大20％（范围7–38％）。1例发生轻度并发症。术后15天无需任何治疗即可解决。在最后一次随访期间，没有发生并发症和复发的便秘，在任何情况下，均在5个月至1年之间。

临床意义 使用拉力螺钉固定三联骨盆截骨术可导致骨盆管加宽，并获得令人满意的结果，且无重大并发症。该技术快速，不需要昂贵的植入物并且相对简单。需要进一步的病例来确定手术的成功率和并发症风险。
