Fifteen dogs with stenosis of the lumbosacral portion of the spinal canal were treated by laminectomy, bilateral facetectomy, and foraminotomy. Concomitant disk extrusion, spondylosis, fracture, infection, neoplasia, hemivertebrae, and spinal bifida were not associated with the stenosis and attendant cauda equina compression. The predominant neurologic signs were intermittent hindlimb lameness and motor weakness; hindlimb muscle atrophy; presumed paresthesia with resultant dermatologic manifestations from self mutilation of the hindlimbs, tail, perineum, anal area, and genitalia; urinaryu or fecal incontinence, or both; and consistently elicitable pain on manipulation of the lumbosacral spine. Surgical decompression of the stenotic canal alleviated the clinical signs in all cases.
对15只患有腰椎管狭窄症的犬进行了椎板切除术、双侧关节突切除术和椎间孔切开术治疗。同时存在的椎间盘突出、脊椎关节强硬、骨折、感染、肿瘤、半椎体和脊柱裂与狭窄及伴随的马尾神经受压无关。主要的神经学体征为间歇性后肢跛行和运动无力；后肢肌肉萎缩；推测有感觉异常，导致后肢、尾巴、会阴、肛门区域和生殖器自残的皮肤表现；尿失禁或大便失禁，或两者皆有；以及在操作腰骶椎时始终可诱发疼痛。对狭窄椎管进行手术减压在所有病例中均缓解了临床症状。
