半椎体切除治疗先天性脊柱侧后凸畸形的临床疗效

Clinical efficacy of hemivertebra resection for treating congenital kyphoscoliosis

目的探讨半椎体切除治疗先天性脊柱侧后凸畸形的临床效果及应用价值。方法选取该院2011年1月至2013年1月收治的30例先天性脊柱侧后凸合并半椎体畸形患者为研究对象。其中,单纯半椎体、无结构性弯曲患者12例,行后路半椎体切除、短节段椎弓根螺钉固定术;合并前凸、半椎体凸向腹侧患者3例,行前路半椎体切除合并植骨融合固定术;合并结构性代偿弯患者15例,行后路经椎弓根半椎体切除、长节段矫形代偿弯固定融合术。对所有患者手术治疗临床效果进行对比分析。结果后凸术后平均Cobb角、末次随访平均Cobb角分别为(8.6±3.14)°、(11.2±7.23)°,脊柱后凸最终矫形率为58.6%;侧凸术后平均侧凸Cobb角(12.8±5.47)°,末次随访平均(16.2±6.24)°,脊柱侧凸最终矫形率为66.5%。脊柱后凸、侧凸手术治疗后平均Cobb角明显小于术前,差异有统计学意义(P<0.05),脊柱后凸、侧凸均明显好转,术后未出现明显并发症,患者较满意。结论半椎体切除治疗先天性脊柱侧后凸畸形效果显著,脊柱侧后凸矫形率高,值得临床上进一步研究。

Objective To explore the clinical efficacy and application value of hemivertebra resection for treating congenital ky‐phoscoliosis .Methods 30 cases of congenital kyphoscoliosis and hemivertebral deformity in our hospital from January 2011 to Jan‐uary 2013 were selected as the research subjects .Among them ,12 cases of simple vertebral and non‐structural bending were per‐formed the posterior hemivertebral resection and short segment pedicle screw fixation ;3 cases of complicating lordosis and hemiver‐tebral protruding to the ventral side were performed the anterior hemivertebral resection and bone graft fusion fixation ;15 cases of complicating structural compensatory curve were performed the posterior transpedicle hemivertebral resection and compensatory bend long segment fixation and fusion .The clinical effects of surgical treatment for all patients were performed the comparative a‐nalysis .Results The mean postoperative kyphosis Cobb angle and the average final follow‐up Cobb angle were （8 .6 ± 3 .14） °and （11 .2 ± 7 .23） °respectively .The ultimate orthopedic rate of kyphosis was 58 .6% ;the average postoperative Cobb angle and and the average final follow‐up Cobb angle of scoliosis were （12 .8 ± 5 .47）°and （16 .2 ± 6 .24）°respectively ,the final orthopedic rate of scoliosis was 66 .5% .The mean Cobb angle of kyphosis and scoliosis after operation was significantly less than that before opera‐tion ,the difference was statistically significant（P＆lt; 0 .05） .Kyphosis and scoliosis were significantly improved .No significant post‐operative complications occurred .The effects were satisfied by the patients .Conclusion The hemivertebral resection has significant effect for treating congenital kyphoscoliosis with high kyphoscoliosis orthopedic rate and is worthy of further clinical study .
