目的：观察手术治疗脊髓拴系综合征（ＴＣＳ） 的术后功能改善情况。方法：对１１２ 例经ＭＲＩ明确诊断的脊髓拴系综合征的患者采用显微外科方法进行手术治疗。在神经电生理监测下进行硬膜外松解、切除脂肪瘤及纤维瘢痕，硬膜内松解粘连的神经根与脊髓，切断增粗的终丝。其中７２ 例得到２ 年以上随访。结果：手术年龄在１０ 岁以下者，术后感觉、运动、括约肌功能和并发症改善率达６０ ％ 以上，而年龄大于１０ 岁者却不足４０ ％ 。经Ｋｅｎｄａｌｌ 等级相关检验，手术年龄与术后功能改善呈正相关（ Ｐ＜ ０－０１） 。结论：ＭＲＩ是最可靠的诊断方法；诊断一经成立宜及早手术，手术年龄越小，术后效果越好；手术采用显微外科技术，并辅以神经电生理监测，可避免加重损伤。
Objective: To observe the surgical treatment of tethered cord syndrome (TCS) postoperative functional improvement. Methods: One hundred and twelve patients with tethered cord syndrome diagnosed by MRI were treated by microsurgery. Epidural electrophysiological monitoring of epidural detachment, removal of lipoma and fibrous scars, epidural adhesion and release of nerve roots and spinal cord, cut thickening of the terminal wire. 72 cases were followed up for more than 2 years. Results: The improvement rate of sensory, motor, sphincter function and complication was less than 40% in those under 10 years of age, but less than 40% in those older than 10 years. The Kendall rank correlation test showed that the operative age was positively correlated with postoperative improvement (P <0-01). Conclusion: MRI is the most reliable diagnostic method. Once the diagnosis is established, it should be operated as soon as possible. The younger the operation, the better the postoperative effect. The surgery using microsurgical techniques combined with electrophysiological monitoring can avoid aggravating the injury.
