Subchondral lucencies (SCL) occur in the equine medial femoral condyle (MFC) and can cause lameness and impair performance. Treatment of MFC SCL has evolved over the last 40 years from rest alone to cyst injection to several surgical procedures. Horses most commonly develop MFC SCL in the first 18 months of life, and expectations for performance and sales can impact therapeutic decisions. These complications mean that a single treatment plan cannot be applied to every SCL. An additional issue is accurate long-term performance data. Long-term follow-up can also be difficult to obtain due to horse movement, confidentiality issues after sales, and the complexities of finding new owners and getting their cooperation. This short communication reviews available racing information from publications reporting treatment of MFC SCL and provides long-term follow-up racing data on 13 horses treated with a transcondylar screw. Horses receiving a transcondylar screw raced as well as horses treated with other procedures and had longer careers, further supporting the use of this technique in the treatment of MFC SCL.

具有股骨内侧髁软骨下透明区的马的治疗选择和长期结果

软骨下透明区 (SCL) 发生在马内侧股骨髁 (MFC) 中，可导致跛行和损害性能。在过去的 40 年里，MFC SCL 的治疗已经从单纯的休息发展到囊肿注射，再到几种外科手术。马最常在生命的前 18 个月内患上 MFC SCL，对性能和销售的预期会影响治疗决策。这些并发症意味着单一的治疗计划不能适用于每个 SCL。另一个问题是准确的长期性能数据。由于马匹移动、售后保密问题以及寻找新主人和获得合作的复杂性，也很难获得长期跟踪。这篇简短的通讯回顾了报道 MFC SCL 治疗的出版物中的可用赛马信息，并提供了 13 匹使用经髁螺钉治疗的马的长期跟踪赛马数据。接受髁突螺钉的马匹与接受其他手术治疗的马匹比赛，并且有更长的职业生涯，进一步支持使用该技术治疗 MFC SCL。
