OBJECTIVE  The aim of this article was to report the surgical technique and clinical outcome of a modified cross-pin technique for the treatment of distal tibial physeal fractures in cats without postoperative external coaptation. STUDY DESIGN  This study was a retrospective clinical study. ANIMALS  A total of 9 cats were presented with fracture of the distal tibial physis. MATERIALS AND METHODS  Medical records from July 2014 to September 2018 were reviewed. In all cases, a second medial and a craniolateral Kirschner wires were added to the traditional cross-pin technique. Information reviewed included orthogonal radiographs pre- and post-surgery and at subsequent re-examinations, subjective assessment of lameness and passive range of motion, veterinary clinical assessment and completion of a functional questionnaire (feline musculoskeletal pain index) at the time of writing this report. Eight owners completed the questionnaire. The mean questionnaire follow-up time was 12.7 months. RESULTS  Uncomplicated fracture healing occurred in all patients. Two patients required implant removal due to Kirschner wire migration and protrusion through the skin at 5 and 12 months post-surgery. No other complications were noticed. Eight patients had an excellent outcome, and one patient had a good outcome. CONCLUSION  Distal tibial physeal fractures in cats can be treated successfully with the use of a modified cross-pin technique and without the use of external coaptation. Prognosis should be considered favourable for this type of fracture.

使用四针改良十字针技术修复猫远端胫骨物理骨折。

目的本文的目的是报告一种改良的交叉销技术在没有术后外部适应的情况下治疗猫胫骨远端骨干骨折的手术技术和临床结果。研究设计本研究是一项回顾性临床研究。动物共有9只猫出现胫骨远端骨折。材料与方法回顾了2014年7月至2018年9月的病历。在所有情况下，第二根内侧和颅外侧克氏针都被添加到传统的交叉钉技术中。审查的信息包括术前和术后以及后续复查时的正交X线照片，对la行和被动运动范围的主观评估，在撰写本报告时进行兽医临床评估并完成功能性问卷调查（猫肌肉骨骼疼痛指数）。八位所有者填写了问卷。平均问卷随访时间为12.7个月。结果所有患者均发生了简单的骨折愈合。两名患者由于手术后5个月和12个月时Kirschner线迁移和穿过皮肤突出而需要去除植入物。没有发现其他并发症。8例患者预后良好，1例患者预后良好。结论改良的交叉销技术可成功治疗猫的远端胫骨骨干骨折，而无需使用外部接合。对于这种类型的骨折，应认为预后良好。八位所有者填写了问卷。平均问卷随访时间为12.7个月。结果所有患者均发生了简单的骨折愈合。两名患者由于手术后5个月和12个月时Kirschner线迁移和穿过皮肤突出而需要去除植入物。没有发现其他并发症。8例患者预后良好，1例患者预后良好。结论猫的胫骨远端骨干骨折可以使用改良的交叉销技术成功治疗，而无需使用外部接合。对于这种类型的骨折，应认为预后良好。八位所有者填写了问卷。平均问卷随访时间为12.7个月。结果所有患者均发生了简单的骨折愈合。两名患者由于手术后5个月和12个月时Kirschner线迁移和穿过皮肤突出而需要去除植入物。没有发现其他并发症。8例患者预后良好，1例患者预后良好。结论改良的交叉销技术可成功治疗猫的远端胫骨骨干骨折，而无需使用外部接合。对于这种类型的骨折，应认为预后良好。两名患者由于手术后5个月和12个月时Kirschner线迁移和穿过皮肤突出而需要去除植入物。没有发现其他并发症。8例患者预后良好，1例患者预后良好。结论改良的交叉销技术可成功治疗猫的远端胫骨骨干骨折，而无需使用外部接合。对于这种类型的骨折，应认为预后良好。两名患者由于手术后5个月和12个月时Kirschner线迁移和穿过皮肤突出而需要去除植入物。没有发现其他并发症。8例患者预后良好，1例患者预后良好。结论改良的交叉销技术可成功治疗猫的远端胫骨骨干骨折，而无需使用外部接合。对于这种类型的骨折，应认为预后良好。
