To evaluate the validity and reliability of Thread-tooth Arc-track Screw Plate System (TASPS) in the fixation fusion through expandable channels. ⋯ The fixation fusion through expandable channels by minimally invasive pedicle screw possesses the characteristics of fewer traumas, less intraoperative blood loss, less postoperative pain and rapid recovery. Since its intervertebral fusion rate is similar to the open surgery, it can be viewed as one effective approach for the treatment of lumbar instability diseases. And TASPS is reasonably designed, easy to install and reliably fixed with good reduction effect, which can be applied through expandable channels.

To evaluate the clinical outcomes of primary anterior radical debridement, bone autograft, and sacral rod fixation for the treatment of tuberculosis of the lumbosacral segment. ⋯ Our findings suggest that anterior radical debridement, interbody fusion, and sacral rod fixation can be an effective treatment option for lumbosacral segment tuberculosis.

To explore efficacy and safety of using denervation of dorsal medial branch to treat the low back pain due to lumbar joint origin. ⋯ It is effective by denervation of dorsal medial branch to treat the low back pain due to lumbar joint origin. There are significant difference in low back pain VAS between every two among the preoperation,single branch blocked group,dual branches blocked group and three branches blocked group. There is no significant difference between four branches blocked group and three branches blocked group. In low back muscle strength and average EMG of multifidus, compared with the preoperation group,there is no significant decline in single branch blocked and dual branches blocked group,and there is significant decline in three branches blocked and four branches blocked group. Therefore, single or dual dorsal medial branch blocked is safety. Among the dual branches blocked group, dorsal medial branches of the involved and the upper level blocked should be given priority to. There is a certain risk in three or four dorsal medial branches blocked which should be used with caution.

To evaluate the efficacy and clinical outcome of reduction and pedicle screws fixation at the fracture level with the approach through para-vertebral muscles in treating thoraeolumbar fractures. ⋯ Using reduction and short-segment pedicle screws fixation at the fracture level through para-vertebral muscles approach is an effective method in treating thoracolumbar fractures. The method has advantages of simple operation,easy establishing screw, short operative time, less blood loss, which can obtain good reduction and stable, reliable fixation after operation.

To evaluate the efficacy and clinical outcome of the treatment of thoracolumbar single compression fracture by using in situ rod rotation reduction and short segment pedicle screw at the fracture level. ⋯ The thoracolumbar single compression fracture can obtain and maintain a good restoration by using the technic of in situ rod rotation reduction and short segment pedicle screw at the fracture level. The technique should be highly recommended.
