Abstract:
[Objective]To evaluate surgical outcomes of hemivertebra resection only via posterior approaches followed by short-segment transpedicular instrumentation for correction of the congenital scoliosos. [Method]A group of patients with a single hemivertebra between the ages 5-16 years 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.Radiographic evaluation were conducted before and after operation and at follow-up visits.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 cases in this study showed satisfied results.The mean Cobb's angle of segment curve was 41.5? before surgery and 15.1? after surgery with a 63.6% correction,and 14.7? at the lastest follow-up assessment with a 64.6% correction;total main curves improved from 46.9?to 18.4?,with a 60.8% correction;17.5?at last follow-up,with a 62.7% correction;the correction ratio for kyphosis was from 15.4?kyphosis to normal physical profile;cranial and caudal compensartory curves were obviously improved.[Conclusion]Hemivertebra resection and short-segment transpedicular instrumentation could be performed only through posterior approach,which had exerted satisfactory 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.
