Abstract

Abstract:

BACKGROUND: The translaminar facet joint screw fixation and interbody fusion in the treatment of spinal disorders is a unique fixation method which can be used for degenerative lumbar spinal fusion.
OBJECTIVE: To observe the clinical effect of the minimally invasive transforaminal lumbar interbody fusion combined with unilateral lumbar pedicle screw and translamina facet screw fixation versus conventional posterior lumbar interbody fusion combined with bilateral pedicle screw fixation for the treatment of low back pain.
METHODS: Forty-nine patients had lumbar disc herniation with lumbar spinal mild instability were selected from Wu Jing Zong Dui Hospital of Guangdong Province between June 2010 and June 2012. All the patients were treated with posterior decompression and interbody fusion and internal fixation. Among the 49 patients, 24 patients were treated with minimally invasive transforaminal lumbar interbody fusion combined with unilateral lumbar pedicle screw and translamina facet screw fixation, and 25 patients were treated with conventional posterior lumbar interbody fusion combined with bilateral pedicle screws fixation. The clinical effects of the two methods above were compared.
RESULTS AND CONCLUSION: There were no significant differences of vertebral fusion rate, Japanese Orthopedic Association score and visual analogue scale score between two groups (P > 0.05). These two approaches had similar clinical outcomes for single-level lumbar degenerative disorders with no instability. These two methods could effectively improve intervertebral fusion rate, make the small joint stability, relieve clinical symptoms and make outpatient follow-up satisfaction. In addition the incision length, operative time, intraoperative blood loss, postoperative incision drainage of minimally invasive transforaminal lumbar interbody fusion combined with unilateral lumbar pedicle screw and translamina facet screw fixation technology were significantly reduced (_P< 0.05), and it indicated that the method had the advantages of small trauma and simple operation.
