ABSTRACT
Objective To observe the effect of H shaped decalcified bone grafting on spinal fusion and anti conglutination by posterior approach and to evaluate its values in the application in spinal posterior approach surgery. Methods Total laminectomy was performed on 23 cases of severe spinal stenosis and 31 cases of intraspinal tumor for decompression. Thorough decompression of the nerve roots was performed on the former following total laminectomy while exploration and excision of the neoplasm were done on the latter. Then, H shaped decalcified bone grafts were inlaid between spinous processes and transverse processes to cover the lamina defection and overlap the adjacent segments in all cases. At last, the spinal internal fixation or plaster external fixation were used to stabilize vertebral segments according to the economic status of patients. The average time of follow up was 21 months (18~31 months). Results All patients got successful segmental spinal fusion within 8 months. Clinical symptoms were obviously alleviated in 43 cases at the end of follow up but symptoms recurred 12 months after operation in other 11 cases(all were tumor patients). Conclusion H shaped decalcified bone graft is valuable in spinal fusion and anti conglutination in spinal posterior approach surgery.
