A prospective study into the use of transarticular external skeletal fixation in the treatment of proximal interphalangeal instability was undertaken. Only dogs with soft tissue injuries were included. All the dogs except one were greyhounds or related breeds. A hypothesis was proposed that if the articular surfaces were held in normal congruency for a period of time then the development of periarticular fibrosis would alone give sufficient joint support. Joint congruency was maintained by the application of a unilateral external skeletal fixator for approximately three weeks. Complications were common and were due to frame impingement on the neighbouring digit, pin tract infection and pin loosening, and all resolved following frame removal and antibiotic therapy. Careful pin placement and prophylactic antibiotic treatment prevented complications in subsequent cases. All dogs returned to normal function with no lameness, with the exception of one racing greyhound which had a recurrence of the instability.
对使用经关节外骨骼固定治疗近端指间关节不稳定进行了一项前瞻性研究。仅纳入有软组织损伤的犬只。除一只犬外，所有犬均为灵缇犬或相关品种。提出了一个假设，即如果关节面在一段时间内保持正常的一致性，那么关节周围纤维化的发展将单独提供足够的关节支撑。通过应用单侧外骨骼固定器维持关节一致性约三周。并发症很常见，原因是固定架对相邻趾的撞击、针道感染和钢针松动，所有这些在拆除固定架和抗生素治疗后均得到解决。在后续病例中，仔细的钢针放置和预防性抗生素治疗预防了并发症。所有犬均恢复正常功能，无跛行，只有一只赛犬出现了不稳定复发。
