Abstract
 Background: Hemivertebra is one of the common causes of congenital
scoliosis. In cases with curve progression, resection of the hemivertebra
through a combined anterior and posterior approach (CAPA) is one of the usual treatment
modalities which is associated with high morbidity. Recently, hemivertebra
resection through a posterior only approach (POA) is introduced. In the current
study, we are reporting our experience with a single posterior approach. Methods: Ten
patients with lumbar CS who had undergone hemivertebra resection through a POA
with transpedicular instrumentation and short segment fusion, between 2009 and
2012 were retrospectively studied. The main and the compensatory scoliotic
curves and kyphotic curves were measured and compared before surgery and by the
16.1±10 months follow-up. Results: Fusion was
obtained in all of the patients. The mean drop in the main, compensatory and
kyphotic curves were 39.6±6.6 to 11.3±5 degrees, 12.9±5.1 to 7.8±3.4 degrees
and 15.6±8.1 to 2.7±8.2 degrees, respectively (p < /i>
