Abstract

The purpose of this study is to report the effectiveness of transpedicular enucleation and Plate-Rod System for Scoliosis (PRSS) fixation for the treatment of hemivertebral (HV) scoliosis. 16 patients with progressive HV scoliosis underwent the combined procedure. The technique involves excision of cancellous bone to eliminate the blood supply of the cartilaginous endplate and destroy the superior and inferior vertebral end plates, followed by PRSS fixation to correct the main curve and compensatory curve. The mean age at operation was 8.125 ± 1.82 years. The scoliosis curve was corrected from average 55.06 ± 25.68° preoperatively to 21.25 ± 15.51° postoperatively. At the latest follow-up, the Cobb angle was 24.38 ± 16.44°, and there was no significant difference compared with immediate postoperative angle (P > 0.05). No surgical complication of neurological deficits occurred in any patients. Combined use of transpedicular enucleation and PRSS fixation is a safe and effective single-stage method for the management of HV scoliosis in growing children.
