目的　定期随访评价ISOLA器械治疗小儿脊柱侧凸。方法　 41例小儿脊柱侧凸患儿 ,特发性脊柱侧凸 32例 ,神经肌肉性脊柱侧凸 5例 ,其他类型的脊柱侧凸 4例 ,术前、术中、术后均摄X线片 ,记录Cobb角 ,顶椎的移位及旋转 ,躯干偏离中线程度。结果　Cobb角术前平均为 6 6° ,术后 1年为 36° ,术后 2年为 36°。 1年后 ,所有患儿的脊柱均完全融合。顶椎的偏离改善了 14mm。躯干偏离改善了 5mm。特发性脊柱侧凸患儿 1年后有基本的正常活动。术后 4例出现并发症 ,1例深部感染 ,1例骶尾部褥疮 ,1例横钩脱落 ,1例L3 椎弓根螺丝钉脱落。结论　目前有多种后路器械治疗小儿脊柱侧凸。严格掌握手术指征及ISOLA的原理 ,该术式能获得较为满意的疗效 Objective To evaluate ISOLA device for pediatric scoliosis on a regular basis. Methods 41 cases of pediatric patients with scoliosis, idiopathic scoliosis in 32 cases, neuromuscular scoliosis in 5 cases, other types of scoliosis in 4 cases, preoperative, intraoperative and postoperative radiographs were taken , Recorded Cobb angle, vertebral displacement and rotation, trunk deviation from the midline level. Results Cobb angle preoperative average of 6 6 °, 1 year after the 36 °, 2 years after the 36 °. One year later, all children had complete fusion of the spine. Top vertebral deviation improved by 14mm. Body deviation improved by 5mm. Idiopathic scoliosis in children after 1 year of basic normal activities. Postoperative complications occurred in 4 cases, 1 case of deep infection, 1 case of sacrococcygeal pressure sores, 1 case of transverse hook loss, and 1 case of L3 pedicle screw failure. Conclusion There are a variety of posterior devices for pediatric scoliosis. Strict control of surgical indications and the principles of ISOLA, the operation can get more satisfactory results
