收治脊髓纵裂４６例，其中２９例作神经功能状态的临床评价及胫后神经皮层体感诱发电位检查。结果：非手术组随访后神经功能缺陷无改善（Ｐ＞０．０５）；２０例手术组神经功能的临床评分明显增加及胫后神经皮层体感诱发电位明显改善（Ｐ＜０．０５）。表明手术不仅可阻止神经功能缺陷的发展，而且可使其得到改善，是一有效的治疗手段。 Forty-six cases of spinal longitudinal splitting were treated, including 29 cases of neurological functional status of the clinical evaluation and tibial nerve cortex somatosensory evoked potential test. Results: The neurological deficits were not improved in the non-surgical group (P> 0.05). The clinical scores of neurological function and the somatosensory evoked potential of the posterior tibial nerve were significantly improved in 20 cases (P <0.05). Show that surgery can not only prevent the development of neurological deficits, but also make it be improved, is an effective treatment.
