Abstract:

BACKGROUND: The patients with lumbar disc herniation who have no relief after conservative treatment, sensorimotor dysfunction, cauda equina syndrome, unbearable pain and have impact on the work and life should be treated with operation.
OBJECTIVE: To analyze the effect of internal fixation on the treatment of lumbar disc herniation, in-depth explore the clinical examination method of lumbar disc herniation, and to review the literatures on the treatment of lumbar disc herniation with internal fixation.
METHODS: Twenty-three patients with lumbar disc herniation and L5/S1 spondylolisthesis were selected from the Department of Orthopedics, the 306th Hospital of PLA during 29 December 2010 to 27 January 2011, and the patients received posterior lumbar canal decompression and interbody fusion plus pedicle screw system internal fixation after general anesthesia, the Japanese Orthopaedic Association Scores was used to assess before and after operation, and the clinical improvement degree was considered as the surgical treatment criteria. The literatures on the treatment of lumbar disc herniation with internal fixation were screened out, and the experimental methods and results were in-depth analyzed.
RESULTS AND CONCLUSION: The patients treated with short-segment pedicle screw system internal fixation have the advantages of little surgical trauma, more safety and small functional limitation as it just fix single segment. The follow-up results at 6 months after operation showed that improvement rate of Japanese Orthopaedic Association Scores was 80.3%.
