A horse with an open medial luxation of the left metatarsophalangeal joint with extensive cartilage and soft tissue damage and severe contamination of the wound was treated with a two-stage approach. In the first stage, the lesion was cleaned, the luxation was reduced, the wound was sutured and the limb was kept in a cast for a total time of 56 days. In the second stage, an arthrodesis of the affected joint was carried out, using a 13-hole broad 4.5 LCP plate. The limb was then kept in a cast for an additional total time of 56 days. At 70 days after the arthrodesis, the horse was brought in for a final check-up, and only a mechanical lameness remained at that time. No significant complications occurred. Previous case reports on the treatment of metatarso-/metacarpophalangeal luxations include neither cases as severe as the one presented here nor treatment by fetlock arthrodesis. This case illustrates that horses with a complicated, open luxation of the fetlock can be salvaged for breeding purposes.

关节融合术成功治疗严重污染的开放性跖趾关节脱位

一匹左跖趾关节开放性内侧脱位、广泛的软骨和软组织损伤以及伤口严重污染的马采用两阶段方法进行治疗。第一阶段，清理病灶，减少脱位，缝合伤口，四肢石膏固定，共56天。在第二阶段，使用 13 孔宽 4.5 LCP 钢板对受影响的关节进行关节融合术。然后将肢体保持在石膏中额外的总时间为 56 天。关节融合术后第 70 天，这匹马被带去进行最后检查，当时只剩下机械性跛行。没有发生明显的并发症。以前关于跖骨/掌指关节脱位治疗的病例报告既不包括像这里介绍的那样严重的病例，也不包括通过胎儿关节融合术治疗的病例。这个案例表明，具有复杂、开放性脱臼的马可以被抢救用于繁殖目的。
