To determine whether working dogs in New Zealand with carpal injuries and treated with unilateral pancarpal arthrodesis (PCA), using a dorsal hybrid-plating method, are able to return to satisfactory working ability.
Fourteen working dogs presented to the Veterinary Specialist Group (VSG) and the Massey University Veterinary Teaching Hospital (MUVTH) with carpal injuries were prospectively treated using dorsal hybrid plating. Dogs were eligible if actively involved in farm, hunting or police work. Dogs had a standardised PCA surgical procedure performed, and similar instructions for post-operative care were provided. Dogs were re-evaluated clinically and radiographically at 6 weeks, 6 months, and 12 months after surgery. A questionnaire was completed by 12 owners, to assess each dog's working ability.
Twelve months following arthrodesis, 10/12 (83%) dogs could perform most or all duties normally. Eleven owners (92%) reported that the result of the surgery met their expectations, and nine owners (75%) were very satisfied with the outcome of the surgery. No owners were disappointed or very disappointed with the surgical outcome. Post-operative complications requiring surgical removal of the implant occurred in three (25%) dogs.
Unilateral PCA using a standardised surgical procedure and dorsal hybrid plating of carpal injuries has a good prognosis for working dogs in New Zealand to return to work.
These results may allow veterinarians to provide a more accurate prognosis to owners of working dogs that have debilitating carpal injury.
确定新西兰患有腕关节损伤并采用背侧混合钢板固定法进行单侧全腕关节融合术（PCA）治疗的工作犬能否恢复到令人满意的工作能力。
前瞻性地采用背侧混合钢板固定法治疗了14只因腕关节损伤就诊于兽医专家小组（VSG）和梅西大学兽医教学医院（MUVTH）的工作犬。积极参与农场、狩猎或警务工作的犬只符合入选条件。对犬只实施标准化的PCA手术程序，并提供类似的术后护理指导。在术后6周、6个月和12个月对犬只进行临床和影像学重新评估。12位犬主填写了一份问卷，以评估每只犬的工作能力。
关节融合术后12个月，10/12（83%）的犬能够正常执行大部分或所有任务。11位犬主（92%）报告手术结果符合他们的期望，9位犬主（75%）对手术结果非常满意。没有犬主对手术结果感到失望或非常失望。3只（25%）犬发生了需要手术取出植入物的术后并发症。
采用标准化手术程序和背侧混合钢板固定法治疗腕关节损伤的单侧PCA对新西兰的工作犬恢复工作具有良好的预后。
这些结果可能使兽医能够为患有致残性腕关节损伤的工作犬的主人提供更准确的预后评估。
