| Summary: | 碩士 === 國立臺北科技大學 === 機電整合研究所 === 103 === As technology continues to progress, diseases of civilization began to appear. Sitting for a long time and life without right posture are bad habits of modern people, it makes lumbar degenerateon appear in young people. Many methods for treatment of lumbar hernination are used in clinical; fusion surgery with cage and lumbar fixations is one of common treatment methods. Someone feel relieve pain indeed and return to normal life, but someone do not. The aim of the study is provide more information about this problem. Finding that placement of cage and length of pedicle screw in spine lumbar biomechanics by finite element methods.
Fusion surgery with cage and lumbar fixateons to treat lumbar degenerateon has been used for many years. There are different results after surgery, and a lot of factors can affect that. In this study, the results of six finite element anylsys show that the placement of cage affects lumbar biomechanics obviously, and the length of pedicle screw does not make it have significant difference. The finding can offer doctors and designers of implants more information to creat new way for treating lumbar diseases.
