Summary

Participants with lumbar spondylosis, degenerative disc disease, spondylolisthesis, scoliosis, or trauma undergoing elective Transforaminal lumbar interbody fusion (TLIF) were recruited. The follow-up period was 24 months for each participant. The eligible patients for this study should be above 18 years old with confirmed indication to TLIF through a posterior approach. Patients with an active infection, symptomatic osteoporosis, immature bone, pregnancy, active malignancy, and previous radiotherapy at the planned surgical site were excluded. Informed consent was signed by each participant before recruitment. We strictly followed the protocols of patient confidentiality and human subjects in the clinical trial implementation. The patients were blinded to the allocated surgical technique before the operation and during the follow-up period of two years. On the one hand, the doctor will assess the patient's physiological function recovery and imaging examinations (such as CT, MRI or X-ray) before and after the operation to understand the changes in the patient's pain index and the effect of intervertebral disc fusion after the operation; on the other hand, It also evaluates the quality of life and the degree of improvement of psychological emotions through the questionnaires of patients before and after surgery.

Conditions

  • Spinal Fusion

Interventions

DEVICE

bone graft delivery system/wiltrom interbody fusion system/wiltrom spinal fixation system

After receiving prophylactic antibiotics according to the local hospital protocol, the patients were generally anesthetized in a prone position. Paramedian or midline posterior sections were conducted, exposing the lumber vertebras encompassing the facet joints. The facet joints were removed, and decompression was performed. The diseased disc nucleus was then excised before filling in the bone substitutes. In the case of the device group, a novel filler tube with an integrated threaded rod, which can be connected to a surgical drill, A PEEK interbody fusion cage was then placed into the disc space followed by fixation with pedicle screws.

The diseased disc nucleus was then excised before filling in the bone substitutes. For the control group, the bone substitutes were filled in the disc space manually using a bone grafting funnel. A PEEK interbody fusion cage was then placed into the disc space followed by fixation with pedicle screws.
