Abstract
|
|
|
Purpose : The purpose of this study is to figure out the effects of Open Laser Microdiscectomy(OLM) on deep muscles by comparing multifidus and longissimus muscle size (cross section area; CSA) of pre and post operation.
Methods : The subjects consisted of forty patients who had OLM. The data were analyzed with paired t-test comparing left and right deep muscle CSA of pre and post-operation ,and both the deep muscle CSA of pre and post-operation, using SPSS ver. 15.0 program.
Results : The results of this study showed a significant difference in deep muscle size (CSA) between pre and post operation (p<.05). Although there was not a meaningful difference between right and left deep muscle size (CSA) in pre operation (p>.05), there was a significant difference between both of them in post operation (p<.05).
Conclusion : Therefore we made the conclusion that the operation causes decrease of muscle tone in deep muscles and muscle imbalance by causing muscle atrophy in the lumbar deep muscle after the operation.
