双侧棘突旁小切口在后路单节段腰椎椎体间融合术中的应用

 目的 比较经双侧棘突旁小切口和传统开放切口行后路单节段腰椎椎体间融合术的效果, 以评估小切口术式的应用价值。方法 2006年 12月至 2008年 6月, 对 70例下腰椎病变患者行后路单节段腰椎椎体间融合术, 将患者随机分为双侧棘突旁小切口组(36例)和传统切口组(34例)。小切口组: 男 20例, 女 16例；年龄 35耀64岁, 平均 52.0岁。传统切口组: 男 16例, 女 18例；年龄 38耀62岁, 平均 53.2岁。分别对两组患者手术基本情况、并发症发生率、肌酸激酶水平、多裂肌的横截面积、术后腰背痛视觉模拟评分(visual analogue scale, VAS)、Oswestry功能障碍指数、椎间融合率进行对比分析。结果 70例患者均获得随访, 时间 12~24个月, 平均 16个月。两组病例手术时间、术中 X线投照次数、并发症发生率、椎间融合率比较差异无统计学意义(P跃0.05), 但小切口组在术中出血量、术后引流量、术后第 1天及第 3天肌酸激酶水平、术后多裂肌横截面积、术后腰背痛 VAS、住: 时间、术后 Oswestry功能障碍指数等方面与传统切口组比较差异均有统计学意义(P< 0.05)。结论经双侧棘突旁小切口或传统切口行后路单节段腰椎间融合术的疗效均满意, 但双侧棘突旁小切口术式具有手术创伤小、住: 时间短、术后恢复快、多裂肌萎缩少等优点。

Application of small surgical incision bilateral spinous process in posterior single segment lumbar interbody fusion

Objective To compare the clinical results of small surgical incision of bilateral spinous process and traditional open surgical incision in posterior single level lumbar interbody fusion,and assess the application value of the small surgical incision of bilateral spinous process in posterior single level lumbar interbody fusion.Methods From December 2006 to June 2008,70 patients with lower lumbar vertebral diseases underwent single segment posterior lumbar interbody fusion.Patients were randomly divided into small surgical incision of bilateral spinous process group(Hereinafter referred to as small incision group) of 36 cases and 34 cases of conventional open group.Small incision group included 20 males and 16 females with an average age of 52.0 years.Traditional open group included 16 males and 18 females with an average age of 53.2 years.Two groups of operative time,blood loss,postoperative drainage,X-ray projection operation frequency,hospital stay,complication rate,creatine phosphokinase (CPK) level,multifidus cross-sectional area,postoperative low back pain visual analogue scale(VAS),Oswestry disability index(ODI),interbody fusion rate were compared,respectively.Results All of 70 cases were followed up for 12-24 months (average,16).There were no statistically differences in the operation time,the number of X-ray projection,complication rate,and fusion rate between the two groups (P＞0.05),but there were significant differences in blood loss,postoperative drainage,the first day and the third day of postoperative the level of CPK,postoperative multifidus muscle cross-sectional area,postoperative low back pain VAS,hospital stay,and postoperative ODI between the two groups (P＜0.05).Conclusion Small surgical incision of bilateral spinous process and traditional open surgical posterior lumbar interbody fusion were satisfied with the efficacy,but small surgical incision of bilateral spinous process with less trauma,shorter hospital stay,and rapid postoperative recovery.
