In a clinical study, 366 radiographs--210 in an abaxioaxial plane, 156 in a dorsopalmar/-plantar view, of 179 bovines affected with laminitis were evaluated. Seven common findings were noted in laminitic claws: In the abaxioaxial plane these were rotation of the pedal bone (34.8%), radiolucency at the tip of phalanx III (31.9%), concave shape of the dorsum of the claw (18.6%), "ski jump" sign (16.2%), and radiolucency in the area of the dorsal laminae (10.0%). In the dorsopalmar/-plantar view a gross irregularity of the solar margin of the pedal bone (49.4%) or radiolucency of the pedal bone tip (34.0%) were evident. Bony proliferations in the region of the dorsal laminae (27.6%) and pedal osteitis at the solar surface of the pedal bone (18.6%) were not evaluated as being typical laminitic changes because they could not clearly be separated from the changes which depend on age. Changes in shape of the extensor process, shape of the dorsal surface of P3 were judged as physiologic variations. The distal displacement (sinking) of phalanx III could not be verified due to the lack of radiologic measurements in normal claws. A statistically proven correlation of laminitis with the septic pododermatitis circumscripta (deep Rusterholz' ulcer) could only be found for the radiolucency of the pedal bone tip.
在一项临床研究中，对179头患蹄叶炎的牛的366张X光片进行了评估，其中210张为远轴面，156张为背掌/跖面视图。在蹄叶炎患蹄中发现了七个常见特征：在远轴面，这些特征包括蹄骨旋转（34.8%）、第三趾骨尖端透光（31.9%）、蹄背侧呈凹形（18.6%）、“跳台”征（16.2%）以及背侧蹄叶区域透光（10.0%）。在背掌/跖面视图中，明显可见蹄骨跖缘严重不规则（49.4%）或蹄骨尖端透光（34.0%）。背侧蹄叶区域的骨质增生（27.6%）和蹄骨跖面的蹄骨炎（18.6%）未被视为典型的蹄叶炎变化，因为它们无法与年龄相关的变化明确区分。伸肌突形状、P3背表面形状的变化被判定为生理变异。由于缺乏正常蹄的放射学测量数据，第三趾骨的远端移位（下沉）无法得到证实。仅在蹄骨尖端透光方面发现了蹄叶炎与局限性化脓性蹄皮炎（深部鲁斯特霍尔茨溃疡）之间具有统计学意义的相关性。
