Abstract

Objectives: To evaluate the outcomes of patients having posterior resection of hemivertebra transpedicular instrumentation to correct and stabilize the deformity. Methods: A retrospective descriptive study was conducted on a cohort of 25 patients diagnosed with congenital scoliokyphosis caused by hemivertebrae who underwent treatment through posterior hemivertebra resection with transpedicular instrumentation at the Spinal Surgery Department of Viet Duc University Hospital from 2018 to 2022. Results: Mean age at operative was 9,16 ± 2,72 years, The mean follow-up duration was 23,48 ± 12,43 months. Mean operation time was 196 ± 47 min with average blood loss of 426,7ml (50 - 1200ml). The segmental scoliosis was 40,2 ± 10,63° preoperatively, 10,82 ± 6,09° postoperatively, and 12,81 ± 6,25° at the latest follow-up. The main scoliosis was 43,08 ± 10,52° preoperatively, 14,27 ± 6,25° postoperatively, and 17,05 ± 6,22° at the latest follow-up. The segmental kyphosis was 29,74 ± 16,42° preoperatively, 10,29 ± 5,65° postoperatively, and 12 ± 6,06° at the latest follow-up. The mean number of fused segments was 3,6 ±1,4. There were no neurological complications, one case of implant failure, one surgical-site infection, all of which were successfully managed. Conclusions: Posterior hemivertebra resection with transpedicular instrumentation to be an effective approach for treatment of congenital deformity caused by hemiverbra. Allowing for excellent correction in both frontal and sagittal planes. Earlier surgery can achieve short fusion and save more mobile segments.
