Seventy-three horses with cervical stenotic myelopathy underwent cervical vertebral interbody fusion (n = 63) or dorsal laminectomy (n = 10). Neurologic function improved in 77% of horses, and 46% of horses achieved athletic function (racing, race training, or pleasure riding) after cervical vertebral interbody fusion for static and dynamic spinal cord compressive lesions. Neurologic status improved in 4 of 10 horses after dorsal decompression for static compressive spinal cord lesions. The duration of clinical signs prior to surgical intervention was shorter for horses that achieved athletic function or improved by at least 2 neurologic grades than for horses that did not improve in neurologic status or improved 1 neurologic grade after cervical vertebral interbody fusion. The number of cervical spinal cord compressive lesions and age of horses did not affect the long-term surgical outcome of cervical vertebral interbody fusion. Seroma formation, implant failure, right laryngeal hemiplegia, and colitis were nonfatal complications associated with cervical vertebral interbody fusion. Dorsal laminectomy and cervical vertebral interbody fusion of static compressive lesions of the caudal cervical vertebral column were associated with fatal postoperative complications, including vertebral body fracture, spinal cord edema, and implant failure.
73匹患有颈椎管狭窄性脊髓病的马接受了颈椎椎体间融合术（n = 63）或背侧椎板切除术（n = 10）。77%的马神经功能得到改善，46%的马在接受颈椎椎体间融合术治疗静态和动态脊髓压迫性病变后恢复了运动功能（比赛、赛前训练或休闲骑行）。10匹接受背侧减压治疗静态脊髓压迫性病变的马中有4匹神经状态得到改善。与未改善神经状态或在颈椎椎体间融合术后仅改善1个神经等级的马相比，恢复运动功能或神经等级至少提高2级的马在手术干预前的临床症状持续时间更短。颈椎脊髓压迫性病变的数量和马的年龄并不影响颈椎椎体间融合术的长期手术效果。血清肿形成、植入物失败、右侧喉偏瘫和结肠炎是与颈椎椎体间融合术相关的非致命并发症。背侧椎板切除术和颈椎椎体间融合术治疗颈椎尾段静态压迫性病变与致命的术后并发症相关，包括椎体骨折、脊髓水肿和植入物失败。
