The medical records of 16 horses with necrosis of the collateral cartilage of the distal phalanx were reviewed. Typical history included a laceration or puncture wound over the affected cartilage, resulting in persistent drainage proximal to the coronary band. All horses had signs of lameness. The duration of drainage prior to admission to the hospital ranged from 5 days to 5 months. The involved cartilages were left front lateral (n = 4), right front lateral (n = 5), left rear lateral (n = 1), right rear lateral (n = 4), left front medial (n = 1), and left rear medial (n = 1). The affected cartilage was curetted or resected in 13 horses, and conservative treatment was used in 3 horses. Follow-up information on 15 horses (2 to 72 months after discharge) revealed that 66% were sound and able to perform at their previous level. One horse was euthanatized 2 months after discharge from the hospital because it had septic arthritis of the distal interphalangeal joint. The outcome of treatment for each horse was evaluated with respect to the duration of drainage and the method of treatment. Horses with drainage of less than 1 month's duration had a better prognosis for eventual soundness, compared with horses with drainage of greater than or equal to 1 month's duration prior to initiation of treatment. Nine of the 13 horses managed surgically and 1 of the 3 horses managed conservatively were sound at follow-up evaluation.
回顾了16匹患有远节指骨副软骨坏死的马的病历。典型病史包括受影响软骨处的撕裂伤或刺伤，导致冠状带近端持续引流。所有马匹均有跛行症状。入院前引流持续时间为5天至5个月。受累软骨分别为左前外侧（n = 4）、右前外侧（n = 5）、左后外侧（n = 1）、右后外侧（n = 4）、左前内侧（n = 1）和左后内侧（n = 1）。13匹马的受累软骨进行了刮除或切除，3匹马采用了保守治疗。对15匹马（出院后2至72个月）的随访信息显示，66%的马恢复健康并能够恢复到之前的运动水平。一匹马在出院2个月后因远节指间关节化脓性关节炎而实施安乐死。根据引流持续时间和治疗方法评估了每匹马的治疗结果。与治疗开始前引流持续时间大于或等于1个月的马相比，引流持续时间小于1个月的马最终恢复健康的预后更好。在随访评估中，接受手术治疗的13匹马中有9匹恢复健康，接受保守治疗的3匹马中有1匹恢复健康。
