文题释义:
腰椎峡部裂:是指腰椎一侧或者双侧上下关节突的骨性连接即腰椎峡部存在骨质缺损不连续。其可以发生在任何节段,以L45多见。腰椎峡部裂多为高强度活动所致的疲劳性骨折,是引起腰椎滑脱的潜在因素,大部分腰椎峡部裂患者无临床症状,部分患者临床症状可主要表现为腰部慢性疼痛。
腰椎峡部裂节段间融合:节段间融合是将病椎与下位椎体进行植骨融合,对于伴有严重滑脱或神经损伤症状的峡部裂其可以较好的恢复椎体间的稳定性,防止椎体滑脱的发生,有效改善症状。但是这种方法加速了临近椎间盘的退变,减少了椎体的活动度。
腰椎峡部裂节段内修复:节段内修复是在峡部裂隙内植骨并在节段内进行固定直接使峡部断端骨性融合,其被证实可以有效保留病椎及临近节段椎体的活动度。但在节段内修复方法发展之初,因为椎体传导的应力主要在椎弓峡部集中,所以众多学者认为单纯固定峡部无法有效恢复椎体生物力学稳定性。但近些年来,随着Buck法、Scott横突-棘突钢丝捆绑法及椎弓钉-椎板钩固定法等节段内修复技术的应用,该方法取得较好的治疗效果。
 
摘要
背景:单纯腰椎峡部裂经保守治疗无效的患者目前多采用节段内骨折内固定联合峡部裂隙植骨的方法,然而这一方法术式多样,尚存在一定争议。
目的:探讨“U”形钛棒系统节段内固定联合峡部植骨治疗单纯腰椎峡部裂的临床疗效。
方法:对2012年5月至2016年5月解放军济南军区总医院骨创科收治的15例单纯性腰椎峡部裂伴或不伴轻度椎体滑脱患者的临床资料进行回顾性分析,均给予“U”形钛棒系统节段内固定联合峡部植骨治疗。观察患者手术一般情况包括手术时间、术中出血量、术后引流量;比较术前及术后3,6,12个月腰椎正侧位X射线、CT、目测类比评分及Oswestry功能障碍指数。
结果与结论:①患者手术时间为(115.0±18.8) min,术中出血(280.0±84.3) mL,术后引流量(61.0±19.6) mL;②随访目测类比评分和Oswestry功能障碍指数,患者疼痛症状及功能均明显改善(P < 0.05);③术后随访无继发腰椎滑脱及临近椎间盘退变发生,无内固定断裂及松动,无感染、神经损伤等并发症出现;④所有患者均获得骨性融合,愈合时间为6-12个月,平均8.2个月;⑤综上说明,“U”形钛棒系统节段内固定联合峡部植骨是治疗单纯腰椎峡部裂的较好选择。

Abstract:

BACKGROUND: When conservative treatment of pure lumbar spondylolysis is ineffective, segmental fixation and bone grafting is a commonly used method. However, surgical methods are various, and have some controversies.

OBJECTIVE: To investigate the effectiveness of U-shape titanium screw-rod fixation system with bone grafting for pure lumbar spondylolysis.
METHODS: Data from 15 patients with pure lumbar spondylolysis or without mild spondylolisthesis, who were treated with U-shape titanium screw-rod fixation system and bone grafting in the Department of Orthopedics of Jinan Military General Hospital from May 2012 to May 2016, were retrospectively reviewed. Operation time, intraoperative blood loss and postoperative drainage were observed. The lumbar spine X-ray, CT, Visual Analogue Scale and Oswestry Disability Index were compared before operation, 3, 6 and 12 months after operation.
RESULTS AND CONCLUSION: (1) The operation time was (115.0±18.8) minutes, the intraoperative blood loss was (280.0±84.3) mL, and the postoperative drainage was (61.0±19.6) mL. (2) By Visual Analogue Scale and Oswestry Disability Index during following-up, pain symptoms and function were significantly improved (P < 0.05). (3) No secondary spondylolisthesis, adjacent vertebral degeneration, internal fixation fracture, loosening, infection or nerve injury occurred during the follow-up. (4) All patients had bony union. The healing time range was 6-12 months, with an average of 8.2 months. (5) In summary, U-shape titanium screw-rod fixation system with bone grafting is a good choice for the treatment of pure lumbar spondylolysis.
