Hemivertebrae are the most frequent cause of congenital scoliosis. Many procedures have been traditionally described to treat this pathology including in situ posterior or anterior-posterior fusion with or without instrumentation, combined anterior and posterior convex hemiepiphysiodesis and hemivertebra excision with fusion. The latter technique can be performed by either a combined anterior and posterior approach, or a single posterior approach.

半椎体畸形是引起先天性脊柱侧凸的最常见原因之一。治疗该疾病的传统疗法多是通过单纯后路或者前后联合入路在凸侧实施半椎体切除或者骨骺阻滞，然后原位骨融合，可同时进行内固定或者不固定。近年来出现的新技术已可采用前后路联合入路或单独后路手术法。
