腰椎後方除圧における非固定群とＬｕｑｕｅ ｒｏｄ固定群の比較検討

Abstract

To evaluate the usefulness of Luqueinstrumentation for posterior surgery, we compared 83 Luque cases (LR) with 50 cases who were Neated with posterior decompression (PD) only.Clinical results as judged by the JOA improvement rate were smilar for/both groups, however the LR group achieved better pain relief the LR group had reduction in new movements or olistheses not only in the decompressed segments but also in adjacent segments.We believe Luque instrumemtation is useful for: 1) patients aged qreater than 65yrs. 2) unstable segments with low back pain 3) multiple degenerative segments or deformity.
