We have observed saddle slip consistently to one side because of a crooked rider, an ill-fitting saddle, asymmetry in a horse's thoracolumbar shape and lameness. Currently, there are no objective data to permit assessment of the relative importance of each factor.
To document the frequency of occurrence of saddle slip in horses with hindlimb lameness compared with other horses. To describe the effect of lameness characteristics and grade, the abolition of lameness by diagnostic analgesia, breed, size, thoracolumbar shape and symmetry and the rider's weight.
One hundred and twenty-eight horses were assessed prospectively, and lameness and saddle slip were assigned a grade before and after diagnostic analgesia. The thoracolumbar shape and symmetry were measured objectively. In 3 horses, the force distribution and magnitude underneath the saddle were measured before and after diagnostic analgesia.
The saddle consistently slipped to one side in 38 of 71 horses (54%) with hindlimb lameness, compared with one of 26 horses (4%) with forelimb lameness, none of 20 (0%) with back pain and/or sacroiliac joint region pain and none of 11 sound horses (0%). The association between saddle slip and hindlimb lameness was significant (Spearman's rank correlation coefficient, ρ = 0.548, P<0.001). Diagnostic analgesia abolishing the hindlimb lameness eliminated the saddle slip in 37 of 38 horses (97%). In 2 horses, the saddle continued to slip after resolution of lameness; one horse had bilateral forelimb lameness and the other horse had concurrent hindlimb and forelimb lameness. The saddle of both these horses was asymmetrically flocked. The saddle slipped to the side of the lamer hindlimb in most horses (32 of 37 [86%]). No horse with saddle slip had significant left-right asymmetry of the back at 4 predetermined sites.
Hindlimb lameness is an important factor in inducing saddle slip. Saddle slip may be an indicator of the presence of hindlimb lameness.
我们观察到，由于骑手坐姿不正、马鞍不合身、马的胸腰椎形状不对称或跛行，鞍座一直向一侧滑动。目前，尚无客观数据可以评估每个因素的相对重要性。
记录与其他马相比，后肢跛行马中鞍座滑动的发生频率。描述跛行特征和等级、诊断性镇痛消除跛行、品种、体型、胸腰椎形状和对称性以及骑手体重对鞍座滑动的影响。
128 匹马进行了前瞻性评估，在诊断性镇痛前后，对跛行和鞍座滑动进行了分级。使用客观方法测量了胸腰椎形状和对称性。在 3 匹马中，在诊断性镇痛前后测量了鞍下的力分布和大小。
38 匹后肢跛行马（54%）的鞍座一直向一侧滑动，71 匹后肢跛行马中有 1 匹（4%）前肢跛行，20 匹（0%）腰背疼痛和/或荐髂关节区疼痛和 11 匹健康马（0%）的鞍座无滑动。鞍座滑动与后肢跛行之间存在显著相关性（Spearman 秩相关系数 ρ=0.548，P<0.001）。诊断性镇痛消除后肢跛行可消除 38 匹马中的 37 匹马（97%）的鞍座滑动。在 2 匹马中，跛行消除后鞍座仍继续滑动；一匹马有双侧前肢跛行，另一匹马有后肢和前肢跛行。这两匹马的马鞍都被不对称地填充了。在大多数马中（32 匹中的 37 匹，86%），鞍座向较严重的后肢跛行侧滑动。在 4 个预定部位，没有马的背部存在显著的左右不对称。
后肢跛行是引起鞍座滑动的重要因素。鞍座滑动可能是后肢跛行的一个指标。
