Short-Term Effect of Unilateral Pedicle Screw Fixed Intervertebral Fusion in Treatment of Degenerative Disc Disease Via MAST QUADRANT Minimally Invasive System

To assess the short-term outcome of unilateral pedicle screw fixed intervertebral fusion surgery for degenerative disc disease via MAST QUADRANT minimally invasive system. Thirty patients with degenerative lumbar disease from September 2009 to September 2011 were enrolled and divided into two groups: (1) unilateral pedicle screw fixed intervertebral fusion via MAST QUADRANT system; and (2) conventional bilateral pedicle fixed intervertebral fusion via open surgery. The perioperative parameters (operation time, intraoperative blood loss, and length of stay) and the follow-up clinical curative effect parameters (VAS and ODI) were compared between two groups. All patients successfully completed surgery and were followed up for more than 1 year. The perioperative parameters of MAST QUADRANT system group were significantly better than the control group (P < 0.05). And the clinical curative effects were similar to conventional surgery (P > 0.05). Unilateral pedicle screw fixed intervertebral fusion via MAST QUADRANT system is a less invasive and safer surgical techniques. It offers a quick recovery and effective surgical option in the treatment of lumbar degenerative diseases.

Repositioning Suture of the Erector Spinae Muscle for Lumbar Spine Surgery via the Posterior Approach: A Prospective Randomized Study

We prospectively studied the effectiveness of the repositioning suture of the erector spinae muscle for lumbar spine surgery using the posterior approach. 393 patients undergoing lumbar spine surgery were randomized to receive the repositioning or conventional suture of the erector spinae muscle. Time to stitch removal and drainage volume was recorded at 24 and 48 h after operation. Hemoglobin loss rate was determined at 48 h post operation and the rate of malunion (redness, swelling and effusion at stitch removal and would disruption after stitch removal) was recorded. Low back pain was evaluated using the visual analog scale (VAS) preoperatively and 6 and 12 months after operation. Time to stitch removal was comparable in lumbar spine surgery patients receiving the repositioning or conventional suture of the erector spinae muscle (P > 0.05). Compared with the conventional suture, the repositioning suture was associated with significantly reduced drainage volume both at 24 (P < 0.01) and 48 h after operation (P < 0.05). Hemoglobin loss rate at 48 h post operation was also markedly lower in lumbar spine surgery patients receiving the repositioning suture than in those receiving the conventional suture (P < 0.01 or 0.05). Furthermore, the malunion rate in lumbar spine surgery patients using the repositioning suture was markedly lower than that in the conventional group (P < 0.05 or 0.001). There was no difference in preoperative VAS scores in both the groups (P > 0.05). Compared with the conventional suture, the repositioning suture was associated with significantly reduced VAS scores both at 24 and 48 h after operation (P < 0.01 in both). The repositioning suture of the erector spinae muscle is superior to the conventional suture in posterior lumbar spine surgery with marked lessened pain and reduced drainage volume.

Surgical Data and Early Postoperative Outcomes after Minimally Invasive Lumbar Interbody Fusion: Results of a Prospective,Multicenter, Observational Data-Monitored Study

Minimally invasive lumbar interbody fusion (MILIF) offers potential for reduced operative morbidity and earlier recovery compared with open procedures for patients with degenerative lumbar disorders (DLD). Firm conclusions about advantages of MILIF over open procedures cannot be made because of limited number of large studies of MILIF in a real-world setting. Clinical effectiveness of MILIF in a large, unselected real-world patient population was assessed in this Prospective, monitored, international, multicenter, observational study. Objective: To observe and document short-term recovery after minimally invasive interbody fusion for DLD. Materials and Methods: In a predefined 4-week analysis from this study, experienced surgeons (≥30 MILIF surgeries pre-study) treated patients with DLD by one- or two-level MILIF. The primary study objective was to document patients’ short-term post-interventional recovery (primary objective) including back/leg pain (visual analog scale [VAS]), disability (Oswestry Disability Index [ODI]), health status (EQ-5D) and Patient satisfaction. Results: At 4 weeks, 249 of 252 patients were remaining in the study; the majority received one-level MILIF (83%) and TLIF was the preferred approach (94.8%). For one-level (and two-level) procedures, surgery duration was 128 (182) min, fluoroscopy time 115 (154) sec, and blood-loss 164 (233) mL. Time to first ambulation was 1.3 days and time to study-defined surgery recovery was 3.2 days. Patients reported significantly (P < 0.0001) reduced back pain (VAS: 2.9 vs 6.2), leg pain (VAS: 2.5 vs 5.9), and disability (ODI: 34.5% vs 45.5%), and a significantly (P < 0.0001) improved health status (EQ-5D index: 0.61 vs 0.34; EQ VAS: 65.4 vs 52.9) 4 weeks postoperatively. One adverse event was classified as related to the minimally invasive surgical approach. No deep site infections or deaths were reported. Conclusions: For experienced surgeons, MILIF for DLD demonstrated early benefits (short time to first ambulation, early recovery, high patient satisfaction and improved patient-reported outcomes) and low major perioperative morbidity at 4 weeks postoperatively.

Correlation of Matrix Metalloproteinases-1 and Tissue Inhibitor of Metalloproteinases-1 with Patient Age and Grade of Lumbar Disk Herniation

The authors studied the nuclear magnetic resonance films and the expression of MMP-1 and TIMP-1 in disk specimens’ of patients who had undergone operations for lumbar disk herniation. Forty-one lumbar disk patients were evaluated imaging for degenerative changes and their disk specimens immunohistochemical expression of MMP-1 and TIMP-1. The degree of degenerative changes was based on magnetic resonance imaging films. Sections of disk immunostained for MMP-1 and TIMP-1 were evaluated semiquantitatively. Patients were categorized in three age groups: <30 years, from 30 to 60 years, and >60 years of age. The expressions of MMP-1 and TIMP-1 were related to patients’ age and degree of degenerative changes. There were statistical differences in the expression of MMP-1 and TIMP-1 between the age and degree of degenerative changes groups. With the degree of degenerative changes, the expression of MMP-1 and TIMP-1 increased obviously. But in old age group, the expression of MMP-1/TIMP-1 was higher than the young groups. The expressions of MMP-1 and TIMP-1 were strongly correlated to the age and the degree of the degenerative changes. An important finding in this study is the unbalance of the expression of MMP-1 and TIMP-1 along with the growth of the age.

Lumbar Disk Degeneration Disease and Aggrecan Gene Polymorphism in Northern Iran

Aggrecan is the major component of intervertebral disk matrix proteoglycan with multiple functional domains. To understand the role of aggrecan polymorphism in a part of exon 12 encoding the CS1 domain in lumbar disk degeneration disease, we have analyzed genomic DNA from 71 patients with the disease and 108 healthy individuals in northern Iran. The AGC1 alleles were determined by PCR followed by gel electrophoresis. Twelve AGC1 alleles ranging from 18 to 29 repeats were detected in patients and controls. The most frequent AGC1 allele was 27, followed by 28 in patients and controls. The shorter AGC1 alleles (≤24 repeats) were more frequent in patients than in controls (37 vs. 16%, P < 0.001). The odds ratio for lumbar disk degeneration was 3.28 (95% confidence interval 1.62–6.65) in carriers of the shorter AGC1 alleles. Our data suggest that carrying shorter AGC1 alleles with less than 24 repeats could predispose a subject to lumbar disk degeneration disease in northern Iran.

Comparison of Discectomy versus Sequestrectomy in Lumbar Disc Herniation: A Meta-Analysis of Comparative Studies

Background

Lumbar disc removal is currently the standard treatment for lumbar disc herniation. No consensus has been achieved whether aggressive disc resection with curettage (discectomy) versus conservative removal of the offending disc fragment alone (sequestrectomy) provides better outcomes. This study aims to compare the reherniation rate and clinical outcomes between discectomy and sequestrectomy by literature review and a meta-analysis.

Methods

A systematic search of PubMed, Medline, Embase and the Cochrane Library was performed up to June 1, 2014. Outcomes of interest assessing the two techniques included demographic and clinical baseline characteristics, perioperative variables, complications, recurrent herniation rate and post-operative functional outcomes.

Results

Twelve eligible trials evaluating discectomy vs sequestrectomy were identified including one randomized controlled study, five prospective and six retrospective comparative studies. By contrast to discectomy, sequestrectomy was associated with significantly less operative time (p<0.001), lower visual analogue scale (VAS) for low back pain (p<0.05), less post-operative analgesic usage (p<0.05) and better patients’ satisfaction (p<0.05). Recurrent herniation rate, reoperation rate, intraoperative blood loss, hospitalization duration and VAS for sciatica were without significant difference.

Conclusions

According to our pooled data, sequestrectomy entails equivalent reherniation rate and complications compared with discectomy but maintains a lower incidence of recurrent low back pain and higher satisfactory rate. High-quality prospective randomized controlled trials are needed to firmly assess these two procedures.
