種々の instrumentation を使用した頚椎前方固定術 : 自家骨移植との比較

抄録

In cases of anterior reconstruction of the cervical spine, we compared, retrospectively, the surgical results and the average hospitalization time of 121 patients who underwent instrumentation surgery with a group of 115 patients who underwent non instrumentation surgery. CERLOCK and BAK Interbody Fusion Cage Cervical were used for interbody fusion cages, and Cervical Spine Locking Plate and Pylamesh were used for internal fixation devises from 1997 to 1999. In the group with instrumentation, the fusion rate was 94% and the average hospitalization time was 18 days. In the group without instrumentation, the results were 89% and 27 days, respectively. The results of this study demonstrate that the use of instrumentation may raise the cost of the operation, but it provides immediate stabilization, and, by shortening the hospitalization time, enables a quicker return to work. Sufficient follow-up periods for assessment is mandatory.
