Pseudarthrosis remains a significant problem in spinal fusion. The objective of our study was to investigate the effects of autologous growth factors (AGF) in instrumented transforaminal lumbar interbody spinal fusion (TLIF). A prospective review was carried out of 23 patients who underwent TLIF with application of AGF, with a minimum 2-year follow-up. Comparison with our historical cohort (without AGF application) was performed. Mean age at surgery was 44.3 years in the AGF treatment group. Twelve had a positive smoking history. Fourteen had undergone previous spinal surgeries. Thirteen received one-level fusions and ten received two-level fusions. The radiographic results showed a fusion rate of 100% in one-level fusions and 90% in two-level fusions. There was no significant difference in pseudarthrosis rates between the AGF treatment group and historical cohort. Excluding the cases with pseudarthrosis, there was faster bony healing in patients who had been treated with AGF application. This study indicates that although AGF may demonstrate faster fusions, it does not result in an overall increase in spinal fusion rates. Further studies are needed before AGF can routinely be used as an adjunct in spinal fusion. 相似文献

Introduction
Restitution of sagittal balance is important after lumbar fusion, because it improves fusion rate and may reduce the rate of adjacent segment disease. The purpose of the present study was to describe the impact of transforaminal lumbar interbody fusion (TLIF) procedures on pelvic and spinal parameters and sagittal balance.Materials and methods
Forty-five patients who had single-level TLIF were included in this study. Pelvic and spinal radiological parameters of sagittal balance were measured preoperatively, postoperatively and at latest follow-up.Results
Age at surgery averaged 58.4 (±9.6) years. Mean follow-up was 35.1 months (±4.1). Twenty-nine percent of the patients exhibited anterior imbalance preoperatively, with high pelvic tilt (17.6° ± 7.9°). Of the 32 (71%) patients well balanced before the procedure, 22 (70%) had a large pelvic tilt (>20°), due to retroversion of the pelvis as an adaptive response to the loss of lordosis. Three dural tears (7%) were reported intraoperatively. Interbody cages were more posterior than intended in 27% of the cases. Disc height and lumbar lordosis at fusion level significantly increased postoperatively (p < 0.05 and p < 0.001). Pelvic tilt was significantly reduced (p < 0.01) postoperatively, whereas the global sagittal balance was not significantly modified (p = 0.07).Conclusion
Single-level circumferential fusion helps patients reducing their pelvic compensation, but the amount of correction does not allow for complete correction of sagittal imbalance. 相似文献55.
Background and purposeTransforaminal lumbar interbody fusion (TLIF) is an effective technique, which can achieve a fusion rate of up to 90%. The minimally invasive approach has become increasingly popular because it is able to minimize iatrogenic soft tissue and muscle injury. Although the minimally invasive TLIF technique has gained popularity, its effectiveness compared with open TLIF has yet to be established. The authors prospectively compared the outcomes of patients who underwent mini-open TLIF with patients who underwent open TLIF.MethodsBetween 2007 and 2008, 50 patients underwent TLIF for grade 1 spondylolisthesis; 25 mini-open TLIF and 25 open TLIF. The mean age in each group was 48 years, and there was no statistically significant difference between the groups. Data were collected perioperatively. Pain and functional disability were measured using a visual analogue scale (VAS) and the Oswestry disability index (ODI) at 3 months, 6 months, 1 year and 2 years. In addition, foraminal and disc height were measured at the same intervals and the fusion was evaluated at 1 year on CT-scan. Soft tissue damage was evaluated by measuring the serum myoglobin and creatine phosphokinase activity.ResultsThe mean VAS improved from 7 to 2.8 and the ODI decreased from 30/50 to 15/50 and fusion rate at 1 year was 98%. There was no statistical difference for the clinical and radiological outcomes between the groups. The mean operative time was 186 min for the open group, 170 min for the mini-open group (P < 0.05) and the mean blood loss was 486 mL for the open group and 148 mL for the mini-open group (P < 0.01).ConclusionThe mini-open TLIF procedure for symptomatic low grade spondylolisthesis is an effective option which achieves similar clinical and radiological outcomes and reduces perioperative morbidity as well as soft tissue damage. 相似文献

Open in a separate windowThis Expert''s Comment discusses the Grand Rounds Case entitled “Minimal Access Bilateral Transforaminal Lumbar Interbody Fusion for High-Grade Isthmic Spondylolisthesis” by Nasir A Quraishi and Raja Y Rampersaud. It puts a technically elegant surgical method for minimally invasive reduction and arthrodesis of isthmic spondylolistheses into the context of short and long term outcomes and questions the motivations for performing such minimally invasive procedures in the absence of any proven mid or long term advantages over more traditional techniques. In addition, the use of BMP in spinal arthrodesis is discussed on the background of recently published IPD metaanalyses from the Infuse™ spinal FDA trials. 相似文献

Minimally invasive transforaminal lumbar interbody fusion (MIS TLIF) has become an increasingly popular method of lumbar arthrodesis. However, there are few published studies comparing the clinical outcomes between unilateral and bilateral instrumented MIS TLIF. Sixty-five patients with degenerative lumbar spine disease were enrolled in this study. Thirty-one patients were randomized to the unilateral group and 34 to the bilateral group. Recorded demographic data included sex, age, preoperative diagnosis, and degenerated segment. Operative time, blood loss, hospital stay length, complication rates, and fusion rates were also evaluated. The Oswestry Disability Index (ODI) score and Visual Analog Scale (VAS) pain score data were obtained. All patients were asked to follow-up at 3 and 6 months after surgery, and once every 6 months thereafter. The mean follow-up was 26.6 months (range 18–36 months). The two groups were similar in sex, age, preoperative diagnosis, and operated level. The unilateral group had significantly shorter operative time, lower blood loss, and shorter hospital time than the bilateral group. The average postoperative ODI and VAS scores improved significantly in each group. No significant differences were found between the two groups in relation to ODI and VAS. All patients showed evidence of fusion at 12 months postoperatively. The total fusion rate, screw failure, and general complication rate were not significantly different. Results showed that single-level MIS TLIF with unilateral pedicle screw fixation would be sufficient in the management of preoperatively stable patients with lumbar degenerative disease. It seems that MIS TLIF with unilateral pedicle screw instrumentation is a better choice for single-level degenerative lumbar spine disease. 相似文献

‘Awake spinal fusion’ is a novel approach to spine surgery that combines modern anaesthetic and surgical technique resulting in improved patient satisfaction and overall outcomes. Along with techniques of regional anaesthesia, minimally invasive or endoscopic surgical techniques are used to minimize surgical dissection and blood loss. Although, it is a relatively new concept with limited supporting evidence till date, it may prove to be highly effective in reducing post-operative hospital stays, in-hospital complications and cost of surgery while at the same time expediting recovery and rehabilitation. The current review focuses on techniques, advantages, limitations and the available evidence on awake spinal fusion. 相似文献
