Filter by:At present, interbody fusion is the mainstream treatment for patients with lumbar spinal stenosis (LSS) and lumbar instability. However, the choice of interbody fusion for LSS patients with lumbar instability remains controversial. Recently, we developed crenel lateral interbody fusion combined with lateral plate fixation(CLIF - LP) for patients with LSS and lumbar instability. This surgical method has many advantages and showed good results for patients with LSS and lumbar instability. Therefore, we propose the following hypothesis: The clinical and imaging efficacy of CLIF-LP in the treatment of LSS patients with lumbar instability is not inferior to that of traditional transforaminal lumber interbody fusion (TLIF).
Lumbar spinal stenosis (LSS) is one of the most common degenerative diseases of the spinal column, with symptoms including low back pain which worsens with ambulation, poor balance, decreased activity due to pain, and a marked decrease in quality of life (QoL). Prevalence rises with age, and current treatment options range from varied conservative management strategies, to surgical intervention with decompression of neural structures. While the effects of surgical decompression on back pain and QoL has been widely researched, the effects of surgery on activity levels is less well understood. Though patients generally have subjective improvements in this parameter after surgery, objective measurements in this patient group have been lacking. This study aims to investigate the effects of decompressive surgery on activity levels in elderly patients with LSS. Measurements of activity will be taken before and after decompressive surgery, as well as with regular intervals during a two-year follow-up period. A better understanding of the effect that LSS has on activity may lead to more patients being able to receive surgical treatment, which is hypothesized to lead to an increase in QoL and less perceived disability amongst this patient group.
Primary objective: To identify older adults with transthyretin cardiac amyloidosis (ATTR-CA) early in the course of the illness, at a time when disease modifying therapies are most effective. The specific aims of this epidemiologic investigation include: 1. To identify subjects with previous lumbar spinal stenosis (LSS) Surgery who have evidence of transthyretin (TTR) amyloid deposits in spinal specimens and could be at risk for ATTR cardiac amyloidosis. 2. To evaluate for ATTR-CA among those with localized TTR in the spinal tissue. The study will also explore the following: 1. The prevalence of amyloid in lumbar spinal stenosis specimens by Congo Red staining. 2. The prevalence of TTR deposits among subjects with amyloid as determined by mass spectrometry. 3. Evaluation of a novel artificial intelligence technique for that can identify amyloid histologically with standard H&E staining. 4. Difference in ATTR-CA prevalence between subjects with TTR and indeterminate amyloid deposits in subject's spine by myocardial uptake of technetium pyrophosphate scan (Tc99-PYP).
To assess the need for additional fusion surgery versus the risk of a revision surgery in patients with degenerative lumbar spinal disease and to assess efficacy and risk of a new ligamentous fixation technique (vertebropexy)
Lumbar spinal stenosis, a common condition in older adults, can cause pain and difficulty walking (i.e., intermittent neurogenic claudication - INC). Patients with INC not infrequently undergo spinal surgery that fails to help them 1/3-1/2 the time. The purpose of this multi-site feasibility study is to prepare for the conduct of a randomized controlled trial to test the efficacy of manual therapy, exercise, and intramuscular electroacupuncture in reducing pain and improving walking ability for those with INC, and ultimately limiting the need for surgical referrals.
The aim of this study is to evaluate the effectiveness and safety of Natural Matrix Protein™ (NMP™) fibers when used in cervical or lumbar interbody fusion in patients with degenerative disc disease (DDD), spinal stenosis, spondylolisthesis undergoing cervical or lumbar interbody spine fusion at no more than 3 adjacent levels.
Our primary objective is to design a cohort to determine the treatment outcome of different surgical interventions of the degenerative lumbar spine highlighting the expediency and value of the current surgical treatment program.
This study is a randomized controlled non-inferiority trial designed to evaluate the impact of implementing the 'Early Recovery After Surgery Clinical Pathway (ERAS CP)' on patient-reported pain levels at the time of discharge following Oblique Lumbar Interbody Fusion (OLIF) surgery
Through a single-center, exploratory clinical study, the safety and effectiveness of using barb wire in the incision and suture of posterior cervical surgery in obese patients were evaluated, providing a basis for its wide clinical application in posterior cervical surgery.
Introduction: Improving postoperative pain management after spinal surgery is a significant challenge for surgeons and anesthesiologists. Pain following spinal surgery, can lead to significant morbidity, limit early mobility, and increase the risk of chronic pain. This trial examines the analgesic effects of dexamethasone as an adjuvant to ropivacaine in wound infiltration after lumbar surgery. Methods: In this study, we randomly assigned sixty patients undergoing lumbar laminectomy and/or osteosynthesis into two groups of 30 patients each. The control group (R-group) received only Ropivacaine (150 mg of Ropivacaine 7.5% (20 ml) added to 2 ml of normal saline in the wound infiltration), while the intervention group (RD-group) received Ropivacaine with the addition of dexamethasone (150 mg of Ropivacaine 7.5% (20 ml) added to 8 mg of dexamethasone in the wound infiltration). Both groups were administered patient-controlled analgesia (PCA) with morphine for self-medication. Postoperatively, a blinded evaluator assessed pain at H0, recorded the assessment of surgical scar pain using the Visual Analog Scale (VAS) at 4, 6, 12, 24, and 48 hours, as well as the time to the first opioid request, cumulative morphine consumption, opioid-related side effects, and length of stay. All patients were scheduled for a 3-month follow-up call to monitor chronic pain progression.
