Case records of 202 horses treated for laminitis were reviewed with the intent of determining the long-term outcome and correlating this with digital radiographic findings and with the degree of pain associated with the laminitis. At long-term follow-up 57 horses had returned to athletic soundness (Group 1), 20 horses were intermittently lame (Group 2), 19 horses had permanent severe lameness (Group 3), 97 were dead (Group 4), and 9 were lost to follow up. Using simple regression analysis, functional outcome did not correlate with the degree of rotation (R2 = 0.004) or the presence of distal displacement (R2 = 0.139). Functional outcome did correlate with the clinical grade of laminitis (R2 = 0.504). Horses in Group 1 had significantly less distal phalangeal rotation (5.89 +/- 6.48 degrees) than did horses in Group 2 (11.10 +/- 8.19) and Group 3 (14.50 +/- 10.80), but were not significantly different from Group 4 horses (7.49 +/- 6.57). Of 96 surviving horses, 23 had evidence of distal displacement compared with 54 of 97 non-survivors. Based on these results, horses that develop distal displacement of the distal phalanx are more likely to die than are horses without distal displacement; however, the presence or absence of distal phalangeal displacement and the degree of distal phalangeal rotation cannot be used to predict the outcome of a horse with laminitis. Clinical assessment is a more reliable means of determining the final outcome and should be given precedence over radiographic findings.
回顾了202匹因蹄叶炎接受治疗的马匹的病历，目的是确定其长期预后，并将其与数字化X线影像结果以及与蹄叶炎相关的疼痛程度相关联。在长期随访中，57匹马恢复了运动健康状态（第1组），20匹马间歇性跛行（第2组），19匹马有永久性重度跛行（第3组），97匹马死亡（第4组），9匹马失访。使用简单回归分析，功能预后与旋转程度（R2 = 0.004）或远侧移位的存在（R2 = 0.139）无关。功能预后与蹄叶炎的临床分级相关（R2 = 0.504）。第1组马的远节趾骨旋转（5.89±6.48度）明显少于第2组（11.10±8.19）和第3组（14.50±10.80）的马，但与第4组马（7.49±6.57）无显著差异。在96匹存活的马中，23匹有远侧移位的证据，而97匹非存活马中有54匹有远侧移位。基于这些结果，发生远节趾骨远侧移位的马比没有远侧移位的马更有可能死亡；然而，远节趾骨移位的有无以及远节趾骨旋转程度不能用于预测患蹄叶炎马匹的预后。临床评估是确定最终预后更可靠的方法，应优先于X线影像结果。
