Abstract

Abstract:

BACKGROUND: Clinical treatment of hemivertebrae-induced congenital scoliosis is a complex medical problem.
OBJECTIVE: To find the optimal treatment for hemivertebrae accompanied by congenital scoliosis.
METHODS: Totally 142 hemivertebrae patients who had received surgical treatment in the Department of Orthopedics, the 306 Hospital of Chinese PLA, China from 2010 to 2012 were enrolled. The main surgical treatment was hemivertebrae resection and bone fusion with internal fixation, apical osteotomy for severe scoliosis and spinal shortening with internal fixation, one-stage posterior thoracolumbar osteotomy with internal fixation, spinal decompression with internal fixation.
RESULTS AND CONCLUSION: After treatment, the average correction rate was 70.9% for scoliosis and 71.7% for kyphosis. The follow-up period was 14-35 months, with an average of 23.4 months. By the end of the final follow-up, the loss rate for Cobb’s angle was 7.3% for scoliosis and 7.7% for kyphosis. Follow-up X-ray films showed bone fusion and internal fixation without loosening, fracture, and decompensation. Implementation of one-stage posterior thoracolumbar osteotomy with internal fixation can effectively correct hemivertebrae-induced kyphoscoliosis to obtain a satisfactory spinal sagittal and coronal balance.

Key words: scoliosis, kyphosis, osteotomy, internal fixators
