Eight horses had forelimb lameness which was considered unrelated to primary forelimb pain, but was associated with radiographic abnormalities of one or more cervical vertebrae. There was no evidence of ataxia or weakness. The degree and character of the forelimb lameness varied between horses. In 4 horses, selective local analgesic techniques were used to rule out lameness associated with pain in the forelimb. In the other 4 horses, radiographic examination of the cervical region was performed on the basis of forelimb lameness seen in conjunction with neck stiffness and/or neck pain. Three horses had marked modelling of the synovial articular facet joints in the caudal cervical region; a 4th horse had modelling and a fracture involving the synovial articulation between the 4th and 5th cervical vertebrae. One horse had abnormalities of the intercentral articulation between the 7th cervical and 1st thoracic vertebrae and a discrete mineralised opacity dorsal to it. Two horses had large lucent zones in a vertebral body. One horse had a fracture of the body of the 7th cervical vertebra. Five horses were humanely destroyed, 2 returned to their previous level of activity after a prolonged period of rest and 1 was still being rested at the time of writing.
八匹马出现前肢跛行，这种跛行被认为与原发性前肢疼痛无关，但与一个或多个颈椎的影像学异常有关。没有共济失调或虚弱的迹象。前肢跛行的程度和特征在不同马匹之间有所不同。在4匹马中，采用选择性局部镇痛技术排除与前肢疼痛相关的跛行。在另外4匹马中，根据前肢跛行伴颈部僵硬和/或颈部疼痛的情况，对颈部进行了影像学检查。3匹马在颈椎尾侧区域的滑膜关节面关节有明显的重塑；第4匹马有重塑以及第4和第5颈椎之间滑膜关节的骨折。1匹马第7颈椎和第1胸椎之间的中央间关节有异常，且其背侧有一个离散的矿化不透明区。2匹马在椎体中有大的透亮区。1匹马第7颈椎体骨折。5匹马被人道处死，2匹马经过长时间休息后恢复到以前的活动水平，1匹马在撰写本文时仍在休息。
