The Comparison of Partial Hemivertebrae Resection versus Total Hemivertebrae Resection by posterior only approach with short-segment fixation in children with Congenital Scoliosis. A minimum of a 4-year follow-up study

Abstract

The series of complications involved in hemivertebra resection has not yet led to a precise solution. Therefore, we aim to compare less invasive, partial hemivertebra resection versus total hemivertebra resection for this anomaly in children with a long-term follow-up. From 2011 to 2016, we did a retrospective study on 31 patients with congenital scoliosis associated with hemivertebrae who had a posterior-only approach comprising 16 patients with total hemivertebrae resection (TR), 15 patients with partial hemivertebrae resection (PR), and short-segment fusion. There was 31 congenital scoliosis associated with hemivertebrae patients in both the PR and TR groups, and the average mean age at the time of surgery was 6.3 ± 2.0 and 6.0 ± 1.9, respectively. The PR group had an equipotential correction rate of cobb angle at post-operation (4.3 ± 4.9 and 2.2 ± 3.2, P = 0.174) and the last follow-up (8.3 ± 5.4 and 5.5 ± 2.4, P = 0.087) as the TR group. Partial hemivertebra resection is efficient and secure. A less invasive technique obtained an equivalent well-maintained correction rate to the total hemivertebra resection with a better quality of life outcome of the patients.
