- 目的评估经生长棒撑开术治疗早发性脊柱侧凸(earlyonset scoliosis, EOS)后行最终矫形融合手术患儿的临床效果。方法回顾性分析2007年7月至2014年6月于北京儿童医院接受生长棒撑开技术治疗并行最终融合手术的26例EOS患儿临床资料(男15例,女11例);初次手术平均年龄(5.2±2.6)岁。对病因、最终融合手术年龄、撑开次数、固定节段数及并发症等临床资料进行记录;同时对影像学资料(Cobb角、胸椎高度、脊柱高度)进行测量分析。结果26例均行最终矫形融合手术,平均年龄为(13.2±2.3)岁。26例患儿中,17例为先天性脊柱侧凸,6例I型神经纤维瘤病脊柱侧凸,3例幼儿特发性脊柱侧凸;畸形顶椎位于胸段患儿15例,胸腰段8例,腰段3例;平均每例患儿经历8.2次撑开术,平均撑开时间间隔为(11.7±2.6)个月。术前冠状面主弯Cobb角为(69.3±30.8)°,末次撑开术后为(49.4±22.9)°,最终融合术后为(34.7±14.6)°。T1至T12距离从术前的(15.4±2.7)cm增至末次撑开术后的(22.5±3.6)cm,最终融合术后达(22.9±3.5)cm;T1至S1距离从术前的(24.8±4.2)cm增至末次撑开术后的(32.5±4.8)cm,最终融合术后达(33.6±5.2)cm。12例(46%)患儿共出现并发症14例次,主要为内固定相关并发症(12例次,85.71%),均在撑开手术同时进行翻修;无一例出现神经系统并发症。结论利用生长棒撑开技术治疗EOS患儿可有效控制其脊柱畸形的进展,并保留脊柱及胸廓的生长潜能。最终矫形融合手术的侧凸矫正率约为30%,适用于10岁以上骨骼发育相对成熟、反复出现内固定失败及畸形难以控制的患儿。
- Abstract:
- ObjectiveTo explore the clinical efficacy and complications of definitive fusion after growing-rod treatment of early-onset scoliosis (EOS).MethodsFrom July 2007 to June 2014,26 EOS children (15 boys and 11 girls) underwent growingrod and definitive fusion at our department were selected.The age at initial surgery was (5.2±2.6) years. Etiology, age at definitive fusion, number of distraction, instrumented segments and complications were recorded and reviewed. And radiographic data including Cobb angle of major curve, T1T12 height and T1S1 height were measured.The changes of these parameters were analyzed. ResultsAll of them underwent definitive fusion at an average age of (13.2±2.1) years. The diagnoses were congenital scoliosis (n=17), neurofibromatosis type I scoliosis (n=6) and idiopathic scoliosis (n=3). And the curves were thoracic (n=15), thoracolumbar (n=8) and lumbar (n=3). All of them were operated for 240 times and 188 had distractive options with a mean of 8.2 distractions for each. The mean distractive interval was 11.7±2.6 months. The Cobb angle improved from (69.3±30.8)° to (49.4±22.9)° after the last distractive surgery and 34.7°±14.6° after definitive fusion. The T1T12 height improved from (15.4±2.7) cm to (22.5±3.6) cm after the last distractive option and (22.9±3.5) cm after final fusion. Similarly, T1S1 height improved from (24.8±4.2) cm to (32.5±4.8) cm after the last distractive option and (33.6±5.2) cm after final fusion. In 12 children (46%), 14 complications occurred. And instrumentationrelated complication was the most frequent and there was no neurological complications.ConclusionWith an incidence of complication at 46%, growingrod technique is effective for EOS. It may control curve progression and preserve spinal and thoracic growth ability. Definitive fusion is appropriate for children aged over 10 years with unacceptable or progressive major curve deformity or complications with previous implants.
