文题释义:
腰椎峡部裂:也称椎弓峡部裂或峡部不连,是腰椎一侧或两侧椎弓上下关节突之间的峡部骨质缺损不连续。患者多为青少年,女性发病率为男性4倍;可能为女性腰椎肌肉、韧带相对较薄弱,同时又有孕产等因素共同存在而引起。可发生在任何节段。椎弓峡部裂多发生在L4或L5,也可L4和L5同时发生,其裂隙宽度不一,常发生于椎弓根下2.0-9.0 mm,断端呈锯齿状或圆钝,可有骨桥形成。缺损处常为纤维软骨组织所填。
腰椎滑脱:是由于先天性发育不良、创伤、劳损等原因造成相邻椎体骨性连接异常而发生的,上位椎体与下位椎体部分或全部滑移。正常人的腰椎排列整齐,如果由于先天或后天的原因,其中一个腰椎的椎体相对与邻近的腰椎向前滑移,即为腰椎滑脱。
 
摘要
背景:腰椎峡部裂是引起青少年腰痛的常见原因,保守治疗无效时多采用内固定治疗,方式多种多样,目的是消除疼痛,达到峡部充分的骨性融合。
目的:观察峡部植骨修补联合椎弓根钉棒系统临时单节段固定治疗青少年腰椎峡部裂的临床效果。
方法:应用峡部植骨修补联合椎弓根钉棒系统临时单节段固定治疗青少年腰椎峡部裂症患者32例,所有患者双侧峡部断裂,其中无滑脱型20例,Ⅰ度滑脱12例。内固定前行腰椎X射线、CT及MRI检查,内固定前及内固定后行目测类比评分及Oswestry功能障碍指数评分观察患者疼痛改善情况,采用MacNab评价疗效。内固定后随访行腰椎CT检查观察患者峡部植骨愈合情况。骨愈合后行内固定取出,观察患者固定节段的活动度及相邻节段椎间盘退变情况。
结果与结论:①所有患者均获得峡部骨性愈合,平均愈合时间为7.4个月;②所有患者腰痛目测类比评分和Oswestry功能障碍指数评分较内固定前明显改善(P < 0.05)。③取出内固定后,观察发现临时固定节段的腰椎活动度保留,MRI检查示固定节段的相邻椎间盘信号均较内固定前无明显改变;④结果说明,峡部修补单节段椎弓根钉棒临时固定可有效治疗青少年腰椎峡部裂,峡部骨性愈合确切,临时固定可有效避免临近节段椎间盘退变产生。

Abstract:

BACKGROUND: Lumbar spondylolysis is the common cause of teenagers’ low back pain. It should apply internal

fixation if conservative treatment is invalid. There are a variety of surgeries, which aims to alleviate pain and bony fusion of pars defect.
OBJECTIVE: To observe clinical outcome of bone graft of pars defect plus temporary single segmental pedicle screw rod fixation for adolescent lumbar spondylolysis.
METHODS: A total of 32 adolescent patients of lumbar spondylolysis were treated by bone graft of pars defect plus temporary single segmental pedicle screw rod fixation. All the patients had bilateral spondylolysis. 20 patients had no lumbar spondylolisthesis, while the others had I° spondylolisthesis. All the patients received lumbar radiograph, CT and MRI. Visual analogue scale and Oswestry disability index were utilized to evaluate pain improvement before and after operation. MacNab was used to assess efficacy. Bone graft healing at isthmus was observed with lumbar CT after fixation. The internal fixation was removed after bone fusion, then the motion of the fixed segment and the degeneration of adjacent intervertebral disc occurred were recorded.
RESULTS AND CONCLUSION:(1) Completed bone fusion of pars defect was achieved in all the patients. The average period of bone union was 7.4 months. (2) The visual analogue scale and Oswestry disability index scores were significantly improved after surgery in all patients (P < 0.05). (3) The fixed segment reserved the motion after internal fixation removal. The signal of adjacent intervertebral disc of fixed segment had no changes compared to preoperative MRI. (4) Bone graft to repair isthmus defect plus temporary single segmental screw rod fixation for adolescent lumbar spondylolysis is very effective, the bone fusion is completed, and temporary fixation may effectively alleviate the degeneration of adjacent disc.
