Abstract：
OBJECTIVE: To report the surgical technique, complications, and outcomes of 8 dogs that underwent a unilateral pantarsal arthrodesis stabilized using a circular external skeletal fixator (CESF) construct for the treatment of uni- or multilevel tarsal instability.
METHODS: 8 dogs.
METHODS: Medical records from 2010 to 2023 from 2 small animal hospitals were retrospectively reviewed for dogs undergoing pantarsal arthrodeses stabilized with CESF. Data collected for each dog included signalment, injury etiology, construct configuration, radiographic imaging, antimicrobial use, complications, length of time until construct removal, and outcome based on clinical evaluation by the owner and veterinary surgeon.
RESULTS: 8 dogs met the requirements of inclusion for the study. Dogs had a mean age of 5.5 years (range, 0.42 to 13 years) and weight of 15.1 kg (range, 2.5 to 26.4 kg). Angulated 3- and 4-ring constructs were used in 5 and 3 dogs, respectively, with or without hybridization. Tarsi were stabilized with a mean angle of extension of 124.8° (range, 111.5° to 136.5°). Fixator removal was performed at a mean time of 11.3 weeks (range, 6 to 16 weeks). Complications developed in 4 dogs, 2 of which had poor clinical outcomes despite additional interventions, including recurrent digit trauma and poor limb use postoperatively. Six dogs had excellent outcomes.
CONCLUSIONS: A CESF may be considered as an alternative to plate stabilization when performing a pantarsal arthrodesis. This fixation requires rigorous postoperative care but obviates the need for supplemental postoperative coaptation.

摘要：
目的：报告手术技术，并发症,使用圆形外部骨骼固定器（CESF）构建体治疗单层或多层不稳定的8只狗进行了单侧骨关节固定术。
方法：8只狗。
方法：回顾性分析了2010年至2023年来自2家小动物医院的医疗记录，这些犬接受了用CESF稳定的髌骨关节。为每只狗收集的数据包括信号，损伤病因，构造配置，射线成像，抗菌药物的使用，并发症,直到构造移除的时间长度，和结果基于业主和兽医的临床评估。
结果：8只狗符合纳入研究的要求。狗的平均年龄为5.5岁(范围，0.42至13岁）和15.1公斤的体重（范围，2.5至26.4千克)。在5和3只狗中使用了成角度的3和4环结构，分别,有或没有杂交。Tarsi以124.8°的平均延伸角稳定（范围，111.5°至136.5°)。平均11.3周（范围，6至16周）。4只狗出现并发症，其中2例尽管有额外的干预措施，但临床结局不佳，包括复发性手指创伤和术后使用不良肢体。六只狗有很好的结果。
结论：在进行髌骨关节固定术时，CESF可以被认为是钢板稳定的替代方法。这种固定需要严格的术后护理，但无需补充术后接合。
