The etiology and nature of truncal deformity in idiopathic scoliosis remains unclear. Only 2 methods are effective to halt or correct the spinal deformity. The first is bracing in young patients and the second is surgical correction for severe curve. Bracing is feasible for children with a Cobb angle between 20 degrees to 35 degrees, while surgical correction is the only choice if the Cobb angle is greater than 40 degrees. Recent surgical developments have led to good correction results with reduced operative scale through continuous spinal cord monitoring, evolution of spinal implants, and better perioperative and postoperative care. The newer spinal systems can produce 3-dimensional reconstruction of the deformity and maintain truncal balance afterwards. The newer implants are user-friendly and low-profile. The combined hook/screw application (hybrid) and the all-screw placement methods have become quite popular. With these methods, the correction rate is increased with reduced loss of correction at follow-up. Navigation systems facilitate accurate insertion of pedicle screws into the vertebral bodies, while video-assisted endoscopic instruments allow early ambulation. These methods are useful in cases of thoracic scoliosis. In the future, in order to minimize the operative scale and prevent deformity, important goals are elucidation of the real nature and the causes of scoliosis and restriction of the number of fusion levels by use of emerging technologies.
特发性脊柱侧凸中躯干畸形的病因和本质仍不清楚。只有两种方法可有效阻止或纠正脊柱畸形。第一种是对年轻患者进行支具治疗,第二种是对严重侧弯进行手术矫正。对于Cobb角在20度至35度之间的儿童,支具治疗是可行的,而如果Cobb角大于40度,手术矫正是唯一的选择。最近的手术进展通过持续的脊髓监测、脊柱植入物的改进以及更好的围手术期和术后护理,实现了良好的矫正效果,同时缩小了手术规模。更新的脊柱系统能够对畸形进行三维重建,并在术后维持躯干平衡。新型植入物使用方便且外形小巧。钩/螺钉联合应用(混合)和全螺钉置入方法已相当普遍。采用这些方法,矫正率提高,随访时矫正丢失减少。导航系统有助于将椎弓根螺钉准确置入椎体,而视频辅助内镜器械可使患者早期活动。这些方法在治疗胸段脊柱侧凸时很有用。未来,为了将手术规模降至最低并预防畸形,重要目标是阐明脊柱侧凸的真正本质和病因,并通过使用新兴技术限制融合节段的数量。
