腰椎中线椎间融合术治疗腰椎退行性疾病的临床效果

Clinical effect of midline lumbar fusion in the treatment of degenerative lumbar diseases

目的 探讨腰椎中线椎间融合术治疗腰椎退行性疾病的临床效果。方法 选取2016年5月~2018年5月接受腰椎中线椎间融合术治疗的腰椎退行性疾病患者20例,其中男6例。记录患者手术时间、术中出血量及并发症发生情况。采用功能障碍指数(ODI)评分及疼痛视觉模拟评分(VAS)评估临床疗效。采用Bridwell分级标准评价融合情况。结果所有患者均获得至少12个月随访,平均(17.50±3.53)个月。平均手术时间(172.00±25.73)min,平均术中出血量(213.50±48.70)mL。术后12个月患者腰痛VAS评分、腿痛VAS评分及ODI评分低于术前,差异有统计学意义(P=0.000)。根据Bridwell分级标准,均获得Ⅰ~Ⅱ级骨性融合。随访中未出现螺钉松动、断裂、融合器移位、沉降等并发症。结论 腰椎中线椎间融合术治疗腰椎退行性疾病安全可靠,临床效果良好。

Objective To explore the clinical effect of midline lumbar fusion in the treatment of degenerative lumbar diseases.Methods The clinical data of twenty patients received midline lumbar fusion with degenerative lumbar diseases were selected from May 2016 to May 2018.Operation duration,blood loss and complications of patients were recorded.Oswestry disability index(ODI)and visual analogue scale(VAS)scores for low back pain and leg pain were evaluated the clinical efficacy.Bridwell classification was used to evaluated the fusion.Results All the patients were followed up for at least 12 months,with an average of(17.50±3.53)months.The mean operation time was(172.00±25.73)min and the mean blood loss was(213.50±48.70)mL.VAS scores for low back pain,VAS scores for leg pain and ODI at postoperative 12 months were lower than those at preoperative,and the differences were statistically significant(P=0.000).According to Bridwell classification,Ⅰ-Ⅱfusions were observed by radiography for all the patients.No complications such as screw loosening,rupture,cage displacement,and sedimentation occurred during follow-up.Conclusion Midline lumbar fusion is safe and reliable in the treatment of degenerative lumbar diseases with good clinical results.
