Abstract

Objective: To describe percutaneous fluoroscopy-guided placement of self-drilling, self-tapping, 3.0 mm cannulated headless compression screws (HCS) for surgical reduction of sacroiliac luxation (SIL) in cats, and to document clinical outcome.

Materials and methods: Medical records of cats with SIL, managed by percutaneous fluoroscopy-guided placement of a 3.0 mm HCS, were reviewed. Short-term outcome was assessed by clinical examination and radiographs. Long-term outcome was assessed using an owner questionnaire.

Results: A total of 14 cats, with 17 SIL (11 unilateral and 3 bilateral), were included. Mean postoperative sacroiliac joint reduction was 85%, median sacral purchase was 63% for unilateral and 38% for bilateral HCS, and pelvic canal diameter ratio and hemipelvic canal width ratio were satisfactory in all cases. At follow-up, all cats exhibited satisfactory clinical improvement. Radiographic assessment revealed no implant-related complications of the unilateral HCS; however, screw loosening was observed in 3/6 of bilateral HCS. Owner satisfaction was good, with 10/11 of owners being very satisfied and 1/11 being satisfied.

Clinical significance: Percutaneous fluoroscopy-guided placement of a 3.0 mm HCS is a safe and effective method for unilateral surgical reduction of SIL in cats. Further studies are needed to establish the most appropriate procedure to treat bilateral SIL.

微创放置空心无头加压螺钉复位骶髂脱位14只猫。

目的：介绍经皮透视引导下自钻孔、自攻、3.0 mm空心无头加压螺钉（HCS）在猫骶髂脱位（SIL）手术复位中的应用，并记录临床效果。材料和方法：回顾了经皮透视引导下放置3.0 mm HCS治疗的SIL猫的医疗记录。通过临床检查和x线片评估短期疗效。使用业主问卷对长期结果进行评估。结果：共纳入14只猫，17只SIL（11只单侧，3只双侧）。术后骶髂关节平均复位85%，单侧HCS中位骶骨置换度63%，双侧HCS中位骶骨置换度38%，所有病例的骨盆管直径比和半骨盆管宽度比均令人满意。在随访中，所有猫均表现出满意的临床改善。影像学评估显示单侧HCS无种植体相关并发症；然而，在3/6的双侧HCS中观察到螺钉松动。业主满意度很好，10/11的业主非常满意，1/11的业主满意。临床意义：经皮透视引导下放置3.0 mm HCS是猫单侧SIL手术复位的一种安全有效的方法。需要进一步的研究来确定治疗双侧SIL的最合适的方法。

期刊介绍： Veterinary and Comparative Orthopaedics and Traumatology (VCOT) is the most important single source for clinically relevant information in orthopaedics and neurosurgery available anywhere in the world today. It is unique in that it is truly comparative and there is an unrivalled mix of review articles and basic science amid the information that is immediately clinically relevant in veterinary surgery today.
