Study Overview
Status
Intervention / Treatment
Detailed Description
Methods and analysis: Blinded Randomized Controlled Trial (RCT) will be conducted. A total of 108 participants will be randomly allocated to either a CBT-TLIF group or a PS-TLIF group at a ratio of 1:1. The primary clinical outcome measures are: change in back and lower limb pain with Visual analogue scale (VAS) and change in quality adjusted life years (QALY) will be assessed by EQ-5D-5L. Measurements will be carried out at five fixed time points (pre-operatively and at 3, 6, 12 and 24 months).
Ethics and dissemination: The study had been reviewed and approved by the ethics committee of the Second affiliated hospital of the Wenzhou Medical University, Wenzhou, China(batch:2017-03). The results will be presented in peer-reviewed journals and related website within 2 years after the last operation.

Intervention / Treatment |
---|---|
EXPERIMENTAL: CBT-TLIF group
Patients who are randomised to the CBT-TLIF group will have cortical bone trajectory screws instead of pedicle screws During the opreation.
After preventive use of antibliotics,A small skin incision was made at the fused segment, an entry point for insertion of the CBT screws was drilled in the junction of the center of the superior articular process and 1 mm inferior to the inferior border of the transverse process according to Matsukawa et al.A straight probe was used to create a trajectory for the CBT screws from the entry point to the opposite corner of the pedicle and vertebral body under anteroposterior fluoroscopic guidance.nilateral
facetectomy is performed to gain access to the intervertebral disc.Afterwards, interbody fusion was performed.Device: CBT screws.
|
cortical bone trajectory screws fixation takes the place of traditional pedicle screws fixation will be used in transforaminal lumbar interbody fusion.
|
EXPERIMENTAL: PS-TLIF group
Patients who are randomised to the PS-TLIF group will have pedicle screws During the opreation.
A posterior midline incision, about 6 cm, was performed at the level of interest level under fluoroscopic guidance.
Pedicle screws were inserted into the vertebral body by using freehand, and the inferior and superior articular processes and part pf the lamina were removed by using an osteotome.
To expose the lateral border of the ipsilateral nerve root, the ligamentum flavum was removed.
Afterwards, interbody fusion was performed.Device:traditional pedicle screws.
|
traditional pedicle screws fixation will be used in transforaminal lumbar interbody fusion.
