Abstract：Objective To explore the value of trephine in the treatment of congenital fully-segmented hemivertebra spinal scoliosis in transpedicular hemivertebra resection. Methods 25 patients with congenital fully-segmented hemivertebra spinal scoliosis were treated by hemivertebra resection in our hospital from July 2002 to July 2011, whose data were retrospectively analyzed. There were 8 males and 17 females, with a mean age of 9.6 years old ( range;5-14 years ). 9 patients received traditional transpedicular hemivertebra resection ( group A ) and 16 patients received transpedicular hemivertebra resection using trephine ( group B ). The operation time, blood loss, postoperative correction rate of the scoliotic angle and kyphotic angle and loss rate in the latest follow-up were recorded and compared between the 2 groups. Results All patients were followed up, and the mean follow-up time was ( 21±6.2 ) months. There were no signiifcant differences in age and sex between the 2 groups. The mean operation time was ( 213±33 ) min in group A and ( 174±26 ) min in group B, and the differences were statistically signiifcant ( t=7.23, P<0.05 ). The mean blood loss was ( 840±118 ) ml in group A and ( 710±73 ) ml in group B, and the differences were statistically signiifcant ( t=4.38, P<0.05 ). The correction rate of scoliosis Cobb’s angle immediately after the operation was 81.9%in group A and 83.0%in group B, and the differences were not statistically signiifcant ( t=1.54, P=0.16 );The loss rate of scoliosis Cobb’s angle in the follow-up 1 year after the operation was 4.3%in group A and 3.5%in group B, and the differences were not statistically signiifcant ( t=1.35, P=0.20 ). The correction rate of kyphotic angle immediately after the operation was 77.9%in group A and 74.3%in group B, and the differences were not statistically signiifcant ( t=1.28, P=0.22 );The loss rate of kyphotic angle in the follow-up 1 year after the operation was 7.1%in group A and 5.4%in group B, the differences were not statistically signiifcant ( t=1.12, P=0.29 ). No severe complications related to nerves, blood vessels or internal ifxation instrumentation occurred in both groups during the operation and follow-up. Conclusions Transpedicular hemivertebra resection combined with internal ifxation is an effective way in treating congenital fully-segmented hemivertebra spinal scoliosis, which can obviously not only shorten the operation time, but also reduce blood loss on the premise of increasing the safety of operation using trephine.
