Medical records were reviewed for 12 cattle with septic arthritis of the distal interphalangeal joint that were treated by use of facilitated ankylosis. Information on signalment, clinical signs, digit affected, radiographic findings, and type and duration of treatment were compiled. Owners were contacted for information about the convalescent period, reasons for culling, productivity, and outcome. Outcome was classified as successful or unsuccessful on the basis of lameness, growth pattern, and whether the cattle were subsequently productive. Cause of the septic arthritis was unknown in 9 of 12 (75%) cattle. Eleven of 12 (92%) cattle represented beef breeds. Cattle were lame for a mean of 5.3 weeks before admission. In 8 of 12 (67%) cattle, a trephine was used in the creation of an arthrostomy, the middle and distal phalanges were curetted, and the joint was lavaged with isotonic solution. A drill bit was used in 4 of 12 (33%) cattle to remove articular cartilage and facilitate ankylosis. Convalescent period after discharge from the hospital was 1 to 7 months (mean, 4 months; median, 4 months). After that period, all cattle had an apparently normal gait. Eight of 12 (67%) cattle were maintained in their herd of origin. None of the cattle were culled because of lameness. Two of 12 (17%) cattle had a deformation of the affected digit. According to the criteria for successful outcome that were used in the study reported here, the success rate was 100%. Treatment of septic arthritis of the distal interphalangeal joint by use of facilitated ankylosis is an alternative to digit amputation and is recommended to promote longevity and productivity.
对12头患有远端指间关节化脓性关节炎且采用促进关节强硬术治疗的奶牛的病历进行了回顾。收集了有关信号、临床体征、患病趾、影像学检查结果以及治疗类型和持续时间的信息。联系了畜主，了解恢复期、淘汰原因、生产力和结果等信息。根据跛行、生长模式以及这些奶牛随后是否有生产力，将结果分为成功或不成功。12头奶牛中有9头（75%）的化脓性关节炎病因不明。12头奶牛中有11头（92%）为肉牛品种。奶牛入院前平均跛行5.3周。12头奶牛中有8头（67%）在进行关节造口术时使用了环锯，对中节和远节指骨进行了刮除，并使用等渗溶液冲洗关节。12头奶牛中有4头（33%）使用钻头去除关节软骨以促进关节强硬。出院后的恢复期为1至7个月（平均4个月；中位数4个月）。在此期间过后，所有奶牛的步态明显正常。12头奶牛中有8头（67%）留在了原牛群中。没有一头奶牛因跛行而被淘汰。12头奶牛中有2头（17%）患趾出现畸形。根据本研究中使用的成功结果标准，成功率为100%。采用促进关节强硬术治疗远端指间关节化脓性关节炎是一种替代趾截肢术的方法，建议采用以提高奶牛寿命和生产力。
