ABSTRACT
BACKGROUND:
The purpose of lumbar disc protrusion and spondylolysis operation is not only to anterior decompression and fusion,but also to maintain the mechanical stability of vertebrae by holding the normal stress spot range of instantaneous center of rotation (ICR).OBJECTIVE:
Using mechanical tenet to explain the pathological relationship between lumbar disc protrusion and spondylolysis,and to summarize the treatments for 68 cases with lumbar disc herniation and spondylolisthesis.METHODS:
Totally 68 cases of lumbar disc protrusion and spondylolisthesis suffered lumbago or sciatica simultaneously.All patients were treated by the surgical method containing posterior whole or half laminectomy exploration decompression,discectomy,intervertebral fusion and the short segment posterior pedicle screw reduction and internal fixation.RESULTS ANDCONCLUSION:
All patients received 1.5 years follow-up.According to Stamffer criterion of therapeutic effectiveness,63 patients were good,and 5 patients were average,with 92.6% good rate.Due to abnormal ICR,the pathological disc and spondylolysis were reciprocal causation.Following implantation,the stress of ICR was kept in a normal range,and the anterior sliding power of vertebrae was reduced,which can maintain the mechanical stability of vertebrae.
