Filter by:Patients undergoing surgery for lumbar spinal stenosis will have biopsies of the ligamentum flavum sent to the department of pathology for histologic screening. If the ligament biopsy contains amyloid, patients will receive an echocardiogram, an ecg, biomarker testing, and a bone tracer scintigraphy diagnostic of cardiac amyloidosis.
Building on recent improvements, state-of-the-art functional MRI will be applied as an advanced diagnostic tool for the lumbosacral cord in spinal cord injury (SCI) patients to characterize the remaining neuronal activity of the motor and sensory neurons. Alterations in the activity pattern will reveal the effect upon task-related spinal cord activity of the lower motor neurons and sensory neurons undergoing trauma-induced neurodegeneration, at a spatial specificity that has not been possible so far. Results of this study will be of crucial importance because SCI patients can only profit from regeneration-inducing therapies if spinal neuronal function is preserved below the level of lesion.
This study is designed to evaluate the clinical utility of a known intraoperative neuromonitoring modality (SSEP) using saphenous nerve as the site of stimulation to identify changes to the lumbar nerves which may be at risk during the lateral lumbar interbody fusion (LLIF) procedure.
This is a single center, hybrid retrospective and prospective (ambispective) study to evaluate the safety and efficacy of the Facet Fixation implant. The main objective is to evaluate the efficacy of the Facet Fixation implant compared with pedicle screw fixation to determine successful fusion in radiographic assessment at more than two years. Fusion is mainly defined as any sign of bony fusion between the facet joints or transverse processes when viewing the postoperative CT-scan at over 2 years.
Orthopaedic surgeons are often faced with the clinical dilemma of whether or not to add fusion to a decompression procedure. To decide between these two surgical options, surgeons rely mostly on their experience to conclude if a level is unstable preoperatively or if a specific decompression procedure is likely to destabilize the spine. Recently, the Sagittal Plain Shear Index (SPSI) has been developed as a valid test for determining the degree of spinal (in)stability. The SPSI metric, which can be calculated using flexion-extension radiographs of the lumbar spine, informs the orthopaedic surgeon about whether the spine is stable in and of itself (necessitating decompression surgery only) or whether there is spinal instability (necessitating decompression and additional fusion surgery). The SPSI metric can be calculated using both the validated semi-automated QMA® and more recently developed fully automated Spine CAMP software platforms. The concurrent validity between these two software platforms, as well as the reliability of both of these objective diagnostic indicator for spinal instability have not yet been evaluated. This study will investigate if SPSI-metrics/values obtained with Spine CAMP are equivalent to measurements from QMA®, and will also investigate the repeatability of two measurements of the SPSI taken one hour apart ('test-retest reliability').
Application of 3D printing guide plate in endoscopic spinal surgery
Lumbar spinal surgery is one of the operations performed for the treatment of leg and back pain. Severe pain may occur at postoperative period in patients following lumbar fusion surgery. The ultrasound(US) guided erector spina plan block (ESPB) is injected with a local anesthetic into the deep fascia of the erector spinae. Visualization of sonoanatomy with US is simple and the spread of local anesthetic solution can be seen easily the deep fascia of the erector spinae. In the literature, it has been reported that ESPB provides effective analgesia after lumbar spine surgery. The surgical team visualizes the transverse processes and erector spina muscle during surgery. The aim of this study is to compare US-guided ESPB and surgical infiltrative ESPB for postoperative analgesia management after lumbar spinal fusion surgery.
To investigate the effect of different degrees of fat infiltration on rocuronium use in lumbar surgery was monitored by trapezius muscle relaxation.
The aim of this study is to demonstrate the safety and effectiveness of the Lobster interspinous spacer device for the treatment of Lumbar Spinal Stenosis in comparison to an SSED-based performance goal.
In this clinical trial, equivalence is evaluated by exploratory comparison of changes in X-Ray lesions with test group (Cerazem Master V6) and control group (physical therapy) in patients with intervertebral disc herniation and degenerative stenosis.
