[Safety and efficacy of resection of hemivertebrae by posterior approach in treatment of thoracolumbar kyphoscoliosis in adolescents].
OBJECTIVE
To investigate the safety and efficacy of resection of hemivertebrae by posterior approach in treatment of thoracolumbar kyphoscoliosis in adolescents.


METHODS
twenty-eight patients of kyphoscoliosis, 19 male and 9 female, aged 12 approximately 16, 12 cases with the hemivertebra located in T(12), 10 cases in L(1), and 6 cases in T(11), and with a mean angle of 75 degrees in kyphosis and 48 degrees in scoliosis by the Cobb measurement, underwent resection of the hemivertebrae via the posterior approach and were followed up for 3.5 years.


RESULTS
The mean surgical time was 3.7 hours and the average blood loss was 900 ml. Intercostal neuralgia occurred in one patient and relieved automatically without treatment. Hemothorax and pneumothorax were found in two cases during the operation and were healed after 1 week. Solid fusion was obtained in all the patients. The Cobb measurement was 19 degrees in kyphosis and 14 degrees in scoliosis on average at the final follow-up. No neurological deficit and infection was noted in the late stage. Clinically, no spinal imbalance or trunk shift was observed in all patients.


CONCLUSIONS
Resection of hemivertebrae via posterior approach is safe and effective in the treatment of thoracolumbar kyphoscoliosis in adolescents.
