摘要
[目的]探讨腰椎管狭窄症术后下肢残留麻木的发生率和影响因素。[方法]2001年1月～2003年2月手术治疗56例腰椎管狭窄症患者，术后随访10d，1、3个月、1年和2年，记录患者神经功能和残留症状。[结果]术前82．1％的患者有下肢麻木，术后10d，1、3个月、1年和2年分别有43．6％、39．I％、36．6％、35．3％和35．7％的患者下肢残留麻木，与病程、术前JOA评分和椎管狭窄类型有关，与年龄和神经根直径无关。[结论]腰椎管狭窄症患者术后1个月内下肢麻木恢复最快，术后1年和2年下肢麻木发生率为35．3％和35．7％，推测神经组织的潜在恢复能力影响下肢麻木的发生率。
[ Objective ] To evaluate the incidence of postoperative residual numbness and the factors that influenced numbness in lumbar canal stenosis （LCS） . [ Method] Eighty patients with LCS including 24 males and 32 females, who were 27 -78 years of age with an average age of 61.3, were operated by posterior decompression, and followed 10 days, 1 month, 3 months, 1 year and 2 years after operation. All patients were examined by neurological findings and residual symptoms. [Result] In LCS, there were 82. 1% of patients who complained numbness preoperativety. The incidence of residual numbness was 43. 6%, 39. 1% , 36. 6%, 35.3% and 35.7% after 10 days, 1 month, 3 months, 12 months and 24 months, respectively. The factors that influenced residual numbness were related to stenosis types; JOA score before operation and the type of spinal canal stenosis were independent of age and nerve root diameter. [ Conclusion] The lower limbs＇ numbness recov- ered within 1 month postoperatively. The incidence of postoperative residual numbness was 35.3% and 35.7% in LCS after 1 year and 2 years. It is speculated that the potential of recovery of neural tissue is important for lower limbs residual numbness.
