The Lenke and associates classification system of adolescent idiopathic scoliosis (AIS) was developed to provide a comprehensive and reliable means to categorize all surgical AIS curves. This classification system requires analysis of the upright coronal and sagittal radiographs along with the supine side bending radiographic views. The triad classification system consists of a curve type (1-6), a lumbar spine modifier (A, B, C), and a sagittal thoracic modifier (-, N, +). All three regions of the radiographic coronal and sagittal planes, the proximal thoracic, main thoracic, and thoracolumbar/lumbar are designated as either the major curve (largest Cobb measurement) or minor curves with the minor curves separated into structural and nonstructural types. The recommendations are that the major and structural minor curves are included in the instrumentation and fusion and the nonstructural minor curves are excluded. Overall, the classification system is treatment directed; however, there are other aspects of the radiographic and clinical deformity that may suggest deviation from the recommendations of the classification system. The ultimate goal of this classification system is to allow organization of similar curve patterns to provide comparisons of various treatment methods to provide optimal treatment for each AIS surgical patient.
Lenke及其同事开发的青少年特发性脊柱侧凸（AIS）分类系统，旨在提供一种全面且可靠的方法对所有需手术治疗的AIS曲线进行分类。该分类系统需要分析站立位冠状面和矢状面X线片以及仰卧位侧弯X线片。三联分类系统包括曲线类型（1 - 6）、腰椎修正符（A、B、C）和矢状面胸椎修正符（ - 、N、+）。X线片冠状面和矢状面的所有三个区域，即近端胸椎、主胸椎和胸腰段/腰椎，被指定为主要曲线（最大Cobb角测量值）或次要曲线，次要曲线又分为结构性和非结构性类型。建议将主要曲线和结构性次要曲线纳入内固定和融合范围，而非结构性次要曲线则排除在外。总体而言，该分类系统是针对治疗的；然而，X线片和临床畸形的其他方面可能表明与分类系统的建议存在偏差。该分类系统的最终目标是对相似的曲线模式进行组织，以便比较各种治疗方法，为每位AIS手术患者提供最佳治疗。
