To describe the surgical technique for pantarsal arthrodesis (PTA) in cats according to the principles of percutaneous plate arthrodesis with application of a pre-contoured dorsal plate, without external coaptation and to report the long-term clinical outcome.
Retrospective review was performed of all cats treated by percutaneous plate application using a new pre-contoured dorsal plate for PTA between 2008 and 2011. Inclusion criteria were clinical and radiographic records plus clinical follow-up to at least six weeks. Data recorded included signalment, indication for surgery, postoperative care, and complications encountered. Radiographs were assessed for arthrodesis progression and complications. Outcome was assessed using an owner questionnaire.
Eleven cats were treated for tarsal injuries and met the inclusion criteria. Mean age was 86 ± 45 months, weight 4.50 ± 0.92 kg. The only major short-term complication encountered was wound dehiscence requiring sedation and re-suturing. In the medium-term (23.3 months ± 11.6 months) eight out of nine cats returned to normal activity and one cat showed intermittent lameness. Long-term (34.3 months ±17.5 months) radiographic evaluation was performed in seven out of nine cats; six manifested complete arthrodesis and one sustained plate breakage. Based on owner questionnaire, all nine cats returned to normal activity in the long-term, even the case with plate breakage.
Based on our results, PTA using a custom pre-contoured dorsal plate is a suitable salvage surgery for treatment of severe tarsal injuries in cats.
根据经皮钢板固定术的原则，描述应用预塑形背侧钢板对猫进行跗骨融合术（PTA）的手术技术，无需外部固定，并报告长期临床结果。
对2008年至2011年间所有使用新型预塑形背侧钢板经皮应用于PTA治疗的猫进行回顾性研究。纳入标准为临床和放射学记录以及至少六周的临床随访。记录的数据包括特征、手术指征、术后护理和遇到的并发症。对X线片进行关节融合进展和并发症评估。使用主人问卷评估结果。
11只猫因跗骨损伤接受治疗并符合纳入标准。平均年龄为86±45个月，体重4.50±0.92千克。遇到的唯一主要短期并发症是伤口裂开，需要镇静和重新缝合。在中期（23.3个月±11.6个月），9只猫中有8只恢复正常活动，1只猫表现为间歇性跛行。对9只猫中的7只进行了长期（34.3个月±17.5个月）放射学评估；6只显示完全关节融合，1只出现钢板断裂。根据主人问卷，所有9只猫在长期内都恢复了正常活动，即使是钢板断裂的病例。
根据我们的结果，使用定制预塑形背侧钢板的PTA是治疗猫严重跗骨损伤的合适挽救手术。
