Treatment of thoracolumbar compression fractures using vaginal vertebral pedicle pyramid bone grafting under endoscope / 中华创伤杂志

ABSTRACT

Objective To study methods and effect of granule bone grafting into the vertebral pedicle pyramid under endoscope for treatment of thoracolumbar fractures. Methods There were 26 cases (7 males and 19 females; age range of 32 79 years, average 51.2 years) with thoracolumbar fractures. The fractures included 8 cases (30.8%) of thoracolumbar compression burst fractures with no compression of the spinal cord by broken bone fragments and 18 (69.2%) compression fractures due to senile osteoporosis. Posterior to a preliminary reduction of the lumbar region on the operating table, all cases underwent vaginal vertebral pedicle reduction under endoscope and autogenous or hererogeneous granule bone graft in order to restore the height of the fractured vertebra pyramid. The patients kept in bed for two months postoperatively; meanwhile, the excise for the back muscle was performed. Results The mean follow up period was 3 18 months. Twenty one cases (80.8%) got excellent therapeutic result, four (15.4%) moderate and one (3.8%) poor. (1) The vertebral height recovered average 29%, with mean height loss of 5% through six month follow up. (2) The posterior convex cobb angle of the spine recovered for 10? 20? (mean 13.8?). (3) No lumbago or nerve compression symptoms were found in 21 cases. Conclusions Granule bone graft into vertebra pyramid under endoscope in the treatment of thoracolumbar fractures is a minimally invasive procedure that can enhance the bone capacity of the vertebra, alleviate pain, restore the height of the fractured vertebra pyramid and accelerate bone healing.
