Abstract:

BACKGROUND: Conventional therapies for lumbar spondylolisthesis can result in trauma, bleeding and low back pain. With the vigorous development of spinal biomechanics and novel spinal fixation systems, we have more understanding on the reduction and fusion after spondylolisthesis.

OBJECTIVE: To observe the clinical effects of transforaminal lumbar interbody fusion via the quadrant system on lumbar spondylolisthesis and related biomechanical changes.
METHODS: A retrospective analysis was done in 23 patients with lumbar spondylolisthesis undergoing transforaminal lumbar interbody fusion via the quadrant system admitted from June 2012 to September 2013. Oswestry disability index and visual analog scale score were detected at 3 months and 1 year after treatment, as well as fusion conditions and internal fixation with or without loosening or breakage.
RESULTS AND CONCLUSION: All patients were successfully treated, with no cerebrospinal fluid leakage and nerve injury. Incisions were healed well in all cases except one case suffered from incision infection that was controlled after 10 days of antibiotic treatment. All the patients were followed up. The Oswestry disability indexes and visual analog scale scores were significantly improved at 3 months and 1 year after treatment (P < 0.05), but there was no difference in these two scores at 3 months and 1 year after treatment (P > 0.05). The improvement rates of Oswestry disability index and visual analog scale score were (65.3±14.8)% and (58.2±12.0)%, respectively. These findings indicate that the transforaminal lumbar interbody fusion via the quadrant system is safe and effective to correct lumbar spondylolisthesis, maintains the biomechanical stability, improves patient’s symptoms, reduces the incidence of low back pain and improves the quality of life.
