Eight patients had a radical resection of sacral tumours, and bilateral severance of lumbosacral nerves was required. Their neurological deficits and disturbance of activities of daily living (ADL) were studied. The neurological deficits which occurred were motor dysfunction of the lower limbs, sensory disturbances, and urinary, faecal and sexual dysfunction. Bilateral preservation of the L5 nerve and above was necessary to permit the ability to walk, and bilateral preservation of the S2 nerve and above was necessary to spare urinary, faecal and sexual functions in order to establish ADL. To maintain normal ADL, bilateral preservation of the S2 nerve and above was necessary for walking, and bilateral preservation of the S3 nerve and above was necessary for urinary, faecal and sexual functions.
8例患者接受了骶骨肿瘤根治性切除术，需要双侧切断腰骶神经。对他们的神经功能缺损和日常生活活动（ADL）障碍进行了研究。出现的神经功能缺损包括下肢运动功能障碍、感觉障碍以及泌尿、排便和性功能障碍。为了能够行走，双侧保留L5及以上神经是必要的；为了保留泌尿、排便和性功能以建立ADL，双侧保留S2及以上神经是必要的。为了维持正常的ADL，行走需要双侧保留S2及以上神经，泌尿、排便和性功能需要双侧保留S3及以上神经。
