Abstract

Objective: To describe the change in tibial alignment parameters and complications between bent and straight interlocking nail (ILN) fixation of diaphyseal tibial fractures in dogs.

Study design: Retrospective study.

Animals: A total of 46 dogs with trauma-induced diaphyseal tibial fractures.

Methods: Medical records of dogs with diaphyseal tibial fractures were compiled from 2014 to 2024 and categorized into bent (bILN, n = 27) and straight (sILN, n = 19) ILN groups. Tibial plateau angle (TPA), coronal angulation (CA), and medial mechanical proximal tibial angle (mMPTA) were calculated and compared with the contralateral limb. Medullary canal fill (MCF) was calculated and compared between groups. Intraoperative and postoperative complications were recorded.

Results: Postoperative TPA in the affected limb was 5° higher than in the contralateral limb in the sILN group and 1° higher in the bILN group (p < .0001, p < .0377). Postoperative affected tibias in both groups were in 2° more valgus than their contralateral limb (p < .0059, p < .0301). No differences in mMPTA were noted. The MCF was 6.6% higher in the bILN group than the sILN group (p < .0163). Only one dog in the study developed a complication: moderate ILN bending and valgus. This dog was in the bILN group.

Conclusion: The increased TPA of the sILN group could be attributed to the tibia's natural recurvatum, which a sILN may not fully accommodate.

Clinical significance: While superior tibial alignment was achieved with the bILN, the detrimental effects of a higher TPA with use of a sILN need further investigation.

犬胫骨骨干骨折弯曲或直交锁钉内固定后胫骨对准的比较。

目的：探讨犬胫骨骨干骨折弯曲与直交锁钉（ILN）内固定时胫骨对线参数的变化及并发症。研究设计：回顾性研究。动物：共46只外伤性胫骨骨干骨折犬。方法：整理2014 - 2024年胫骨骨干骨折犬的病历，分为弯曲组（bILN, n = 27）和直骨折组（sILN, n = 19）。计算胫骨平台角（TPA）、冠状角（CA）和胫骨内侧机械近端角（mMPTA），并与对侧肢体进行比较。计算各组间髓管填充量（MCF）并进行比较。记录术中及术后并发症。结果：术后患肢TPA比sILN组高5°，比bILN组高1°(p)。结论：sILN组TPA升高可能是由于胫骨的自然返曲，而sILN可能无法完全适应。临床意义：虽然使用bILN可以实现胫骨上位，但使用sILN时更高TPA的有害影响需要进一步研究。

期刊介绍： Veterinary Surgery, the official publication of the American College of Veterinary Surgeons and European College of Veterinary Surgeons, is a source of up-to-date coverage of surgical and anesthetic management of animals, addressing significant problems in veterinary surgery with relevant case histories and observations. It contains original, peer-reviewed articles that cover developments in veterinary surgery, and presents the most current review of the field, with timely articles on surgical techniques, diagnostic aims, care of infections, and advances in knowledge of metabolism as it affects the surgical patient. The journal places new developments in perspective, encompassing new concepts and peer commentary to help better understand and evaluate the surgical patient.
