Abstract Objective：To study the clinical observation of hemivertebra resection only via posterior approach and short-segment transpedicular instrumentation for congenital scoliosis.Method：30 cases with a single hemivertebra from 5 to 14 years old who underwent operative treatment were evaluated.Hemivertebra resection through posterior approach and short-segment transpedicular instrumentation were used for correction of the scoliosis and kyphosis deformities. Cobb’s angles of the segmental curve， total main curve， cranial and caudal compensatory curves and kyphosis were measured on the posteroanterior and lateral radiographs.Result：The patients in this study showed satisfied results.The mean Cobb’s angles of the segmental curve， total main curve， cranial and caudal compensatory curves and kyphosis were all statistically significant difference among before surgery， after surgery and the lastest follow-up assessment（ P<0.05）. Conclusion：Hemivertebra resection and short-segment transpedicular instrumentation could be performed only through posterior approach， which had exerted satisfiactory correction on congenital scoliosis.If the operation is performed before the maturity of the bone， it will effectively prevent the formation of secondly spinal deformities.It was worthy of clinical application.
