Posterior Hemivertebra Resection in Congenital Spinal Deformities

Abstract

Fully segmented non-incarcerated hemivertebrae have normal growth plates, leading to increasing deformities during further growth and such deformities usually require early surgical intervention to achieve correction of the local malformations; and with early intervention, secondary changes can be avoided. Hemivertebra resection can remove the pathology and correct the deformity completely; thus, it is the primary method to treat this kind of deformity. Posterior hemivertebra resection is a technically demanding procedure with high possibility of multiple complications. However, this study demonstrates that posterior only approach is a relatively safe procedure when done by experienced surgeons in achieving acceptable correction for such spinal deformities 20 patients (13 males/7 females) with rigid spinal deformities at our institution underwent posterior hemivertebra resection of those 13 were scoliosis cases, 4 were kyphosis and 3 were kyphoscoliosis. Preoperative and postoperative radiographic evaluation was performed. Intraoperative and postoperative complications were noted.
