Surgical Experience of Transpedicular Screw Fixation of the Spine
|
|
|
|

Abstract
|
|
|
A total of 21 patients underwent transpedicular spinal instrumentation using the screw-plate system (8) or the screw-rod system(13). We treated 21 cases of spine disease using the above method from February, 1992, to September, 1994. Surgery was
performed for thoraco-lumbar column instability secondary to fracture(7) or spondylolisthesis(14). The most frequent clinical symptom and sign was low back pain with radiating pain accompanied by limitation of straight leg raising, of which
clinical
outcome was excellent. The transpedicular screw fixation allow adequate neural decompression, short segment fixation and prevention of motion limitation of thoraco-lumbar spine. But one of the important complication driven with this method was
root
injury which must be prevented by surgen's thorough knowledge to pedicular anatomy and meticulous operative technique. The appropriate bone fusion will be the acceptable strategy to overcome the eventual possibility of instrument failure.
