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 fusionvia 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 fusionviathe 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 wel as fusion conditions and internal fixation with or without loosening or breakage.RESULTS AND CONCLUSION:Al patients were successfuly treated,with no cerebrospinal fluid leakage and nerve injury.Incisions were healed wel in al cases except one case suffered from incision infection that wascontroled after 10 days of antibiotic treatment.Al the patients were folowed 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 fusionvia 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.
