A 7-month-old Appaloosa foal had bilateral hind limb lameness and was unable to rise from recumbency without assistance. Lameness could be exacerbated by tarsal flexion and a firm swelling at the distomedial aspect of the tibias was associated with a marked pain response when palpated. Radiography revealed enlargement of the distal tibial metaphysis physis (compared with normal), and radiolucent fissure lines extending proximally from the physis into the metaphysis at its medial aspect. Treatment included rest and dietary adjustment. Although clinical signs initially resolved following treatment, the problem recurred when the foal was 14 months old. Further treatment included 7 months of pasture rest without forced exercise, after which the foal was reported to be clinically normal.
一匹7个月大的阿帕卢萨马驹双侧后肢跛行，在没有帮助的情况下无法从卧姿站起。跗关节屈曲会加重跛行，胫骨远端内侧有坚实的肿胀，触诊时伴有明显的疼痛反应。放射学检查显示胫骨远端干骺端骨骺增大（与正常情况相比），在骨骺内侧有从骨骺向近端延伸至干骺端的透亮裂隙线。治疗包括休息和饮食调整。虽然治疗后临床症状最初有所缓解，但这匹马驹14个月大时问题再次出现。进一步的治疗包括在牧场上休息7个月，不进行强制运动，之后据报道这匹马驹临床症状正常。
