In Degenerative Spondylolisthesis, Unilateral Laminotomy for Bilateral Decompression Leads to Less Reoperations at 5 Years When Compared to Posterior Decompression With Instrumented Fusion
Patients diagnosed with degenerative spondylolisthesis patients (DS) and symptomatic lumbar spinal stenosis (LSS) have had standard surgical recommendations of fusion in combination with decompression since the 1990’s. Since the early 1990’s, surgical techniques have become less invasive. What traditionally required wide pedicle to pedicle wide laminectomies with partial facetectomies for central stenosis can now be […]
Aging of the Cervical Spine in Healthy Volunteers A 10-Year Longitudinal Magnetic Resonance Imaging Study
Prospective longitudinal study. Mean follow-up. It is 11.7 + .8 years 223 subjects of original 497 asymtomatic volunteers from asymptomatic volunteers from 1993 to 1996 returned for a repeat MRI more than 10 years after the original MRI. 44.9% Mean age at the time of initial imaging was 39.0 ± 15 years. At the time […]
Microsurgical Treatment of Lumbar Disc Herniation: A Report of 158 Patients with a Mean Followup of More Than 32 Years.
This is a retrospective review of reported outcomes of 158 patients, with a minimum of 25 years followup after microsurgical discectomy of a lumbar herniated disc. The Authors conclude that microsurgical discectomy surgery is an effective technique with high patient satisfaction. This is an important retrospective long term view on microdiscectomy, and certainly is consistent […]
Magnetic Resonance Imaging Predictors Of Surgical Outcome In Patients with Intervertebral Disc Herniation
Data from the Spine Outcomes Research Trial (SPORT) was used to form a retrospective cohort analysis regarding the treatment effects of nonsurgical and surgical patients with lumbar herniated discs. Baseline comparisons of patients who had complete and incomplete MRI studies were reviewed and there was no difference between the populations. Statistical analysis was based on […]
The influence of obesity on the outcome of treatment of lumbar disc herniation: analysis of the Spine Patient Outcomes Research Trial (SPORT).
This publication by Rihn et al represents a retrospective analysis of data collected from the Spine Patient Outcomes Research Trial (SPORT). As has been previously published describing the SPORT trial, participants were either randomized or placed in an observational cohort. This data presented was taken from the as-treated analysis and therefore the randomization effect was […]
The Effects of Smoking and Smoking Cessation on Spine Surgery: A Systematic Review of the Literature.
This systematic review by Jackson and Devine provides us with a current review of the literature in regards to the effects of smoking and smoking cessation on spine surgery. While this review covers spine surgery in general, our reviewed focused soley on the effects related to cervical disc surgery. There are several potential risks that […]
The Norwegian Cervical Arthroplasty Trial (NORCAT): 2-year clinical outcome after single-level cervical arthroplasty versus fusion-a prospective, single-blinded, randomized, controlled multicenter study.
This investigation by Sundseth et al presents a prospective randomized study comparing cervical anterior discectomy and fusion (using interbody cage) versus cervical disc arthroplasty in a Norwegian population. Outcomes were determined at 2 years, which is a relatively short time period. Outcome measures included the Neck Disability Index (NDI), SF36, and EuroQol-5D-3L. Overall, this multicenter […]
Decompression and Coflex interlaminar stabilization compared with decompression and instrumented spinal fusion for spinal stenosis and low-grade degenerative spondylolisthesis: two-year results from the prospective, randomized, multicenter, Food and Drug Administration Investigational Device Exemption trial.
By most definitions, this is a good example of a randomized control trial (RCT). The study populations were well matched and the outcomes were standardly measured. The follow-up rate was greater than 80%. The inclusion criteria included the presence of back pain (VAS of 5/10 or more), along with spinal stenosis and up to grade […]
