Arthrodesis of the proximal interphalangeal joint was used to treat lameness resulting from osteoarthrosis and for closed subluxation in 35 horses. Six horses had bilateral arthrodeses. Several conventional internal fixation techniques and a three converging screw method were used. Criteria for success included the horse performing its previous or intended athletic activity and the owner being satisfied with the outcome. Using these criteria, a successful outcome was obtained in 65% of the 26 animals in which adequate follow-up was available. A successful outcome was observed in four of six horses with bilateral arthrodeses. The internal fixation technique used did not influence the success rate, and the duration of postoperative casting was similar in successful and unsuccessful cases. The success rate of proximal interphalangeal arthrodeses was 46% in the fore limbs and 83% in the hind limbs. Complications included infection, cast ulcers, bone or implant failure, implant loosening, and laminitis.
近端指间关节融合术用于治疗35匹马因骨关节炎导致的跛行及闭合性半脱位。6匹马接受了双侧关节融合术。使用了几种传统内固定技术和一种三枚汇聚螺钉法。成功标准包括马匹能进行先前或预期的竞技活动且主人对结果满意。根据这些标准，在有足够随访资料的26只动物中，65%获得了成功结果。6匹接受双侧关节融合术的马中有4匹获得成功结果。所使用的内固定技术不影响成功率，成功和失败病例的术后石膏固定时间相似。近端指间关节融合术在前肢的成功率为46%，在后肢为83%。并发症包括感染、石膏溃疡、骨或植入物失败、植入物松动和蹄叶炎。
