Cervical Arthroplasty Cost Effectiveness Study (CACES)
RadiculopathyCervical20 moreTo date, no consensus exists on which anterior surgical technique is more cost-effective to treat cervical degenerative disc disease (CDDD). The most commonly used surgical treatment for patients with single- or multilevel symptomatic CDDD is anterior cervical discectomy with fusion (ACDF). However, new complaints of radiculopathy and/or myelopathy commonly develop at adjacent levels, also known as clinical adjacent segment pathology (CASP). It remains unknown to what extent kinematics, surgery-induced fusion and natural history of disease play a role in its development. Anterior cervical discectomy with arthroplasty (ACDA) is thought to reduce the incidence of CASP by preserving motion in the operated segment. ACDA is often discouraged as the implant costs are higher whilst the clinical outcomes are similar to ACDF. However, preventing CASP might be a reason for ACDA to be a more cost-effective technique in the long-term. In this randomized controlled trial patients will be randomized to receive ACDF or ACDA in a 1:1 ratio. Adult patients with single- or multi-level CDDD and symptoms of radiculopathy and/or myelopathy will be included. The primary outcome is cost-effectiveness and cost-utility of both techniques from a societal perspective. Secondary objectives are the differences in clinical and radiological outcomes between the two techniques, as well as the qualitative process surrounding anterior decompression surgery. All outcomes will be measured at baseline and every 6 months till 4 years postoperatively. High quality evidence regarding the cost-effectiveness of both ACDA and ACDF is lacking, to date no prospective trials from a societal perspective exist. Considering the ageing of the population and the rising healthcare costs, the need for a solid clinical cost-effectiveness trial addressing this question is high.
Regeneration in Cervical Degenerative Myelopathy
MyelopathySpinal Cord DiseasesDegenerative (wear and tear arthritis of the spine) Cervical (concerning the neck) Myelopathy (injury to the spinal cord), DCM, is the most common spinal cord disorder of adulthood. In DCM, arthritis of the spine causes compression of the spinal cord. The symptoms of DCM are often mistaken for natural consequences of ageing, including numb and clumsy hands, loss of coordination, imbalance, bladder and bowel problems. The weakness can progress to severe paralysis. Every year approximately 4 individuals in 100,000 undergo surgery for DCM; however, many more individuals are thought to suffer from DCM. The main treatment for DCM is surgery. The aim of surgery is to create space and remove the compression of the spinal cord. This is known to prevent further injury. Unfortunately, the post-operative improvements are often incomplete and many patients remain severely disabled. Improving outcome after surgery represents an important unmet clinical need. Clinical and preclinical findings indicate that the drug Ibudilast can stimulate neuroprotective and regenerative processes in the spinal cord. Ibudilast is well-tolerated and used to treat asthma and post-stroke dizziness in Japan and is currently being investigated for use in treating other neurological diseases. This study will investigate whether daily oral administration of Ibudilast for a maximum of 34 weeks can improve hand function, strength, balance, urinary problems and reduce pain. The study will initially be conducted at three sites in the UK, with more sites added as necessary. Individuals between 18-80 years old, diagnosed with DCM and scheduled for an operation for the first time will be invited to participate in the trial. The study will entail patient questionnaires and clinical assessments before surgery, shortly after surgery and 3, 6, and 12 months after surgery. Moreover, patients will undergo MRI scans pre-operatively and at 6-months postoperatively to determine whether the treatment was successful.

Ossification of Posterior Longitudinal LigamentCervical Spondylosis With MyelopathyThe purpose of this study is to compare the efficacy, safety and imaging outcomes between Anterior Controllable Antedisplacement and Fusion (ACAF) and Laminoplasty in the treatment of severe ossification of cervical posterior longitudinal ligament.
CEM-Plate and CEM-Cage First-In-Human Use Efficacy Study
Neck PainSpondylosis4 moreThe study is a prospective, first-in-human, multi-center, non-randomized, single-arm study to assess the safety and efficacy of the CEM-Cage used with the CEM-Plate in patients who are appropriate candidates for a 2-level anterior cervical discectomy and fusion (ACDF). Fifty patients will be enrolled in the study and, after undergoing a 2-level ACDF, will be evaluated at 4 weeks, 3 months, 6 months, 12 months, 18 months, and 24 months.
Can Prophylactic Foraminotomy Prevent C5 Palsy
MyelopathyCompressive3 moreC5 palsy (C5P) is a well-known, although rare complication of cervical spine decompression surgery. In severe forms, C5P causes debilitating upper extremity weakness involving the deltoids and/or biceps brachii muscles, ultimately diminishing these patients' quality of life. Furthermore, about half of patients with C5P present with sensory deficits and/or intractable pain in addition to the muscle weakness. Prophylactic bilateral foraminotomy at the C5 level during cervical decompression surgery has been studied recently with the hope that it will minimize the risk of developing a C5 nerve root palsy postoperatively. Although the current literature provides some support for this claim, there are insufficient data establishing this technique as a proven measure to reduce the incidence of C5P. In the present study, we seek to evaluate the effect of bilateral foraminotomy on postoperative C5P incidence rates. Bilateral foraminotomy has been correlated with a reduced risk of developing C5P following cervical decompression surgery, but an identical foraminotomy procedure has never been applied in a randomized manner to all qualifying patients in a study. Additionally, prophylactic foraminotomy has only been prospectively studied during laminoplasty. In the proposed study, bilateral foraminotomy will be randomized to patients receiving cervical decompression surgery (laminoplasty, laminectomy, fusion). This is a multicenter randomized trial, including the following sites: Cleveland Clinic, Columbia University Medical Center, and University of Southern California Spine Center. Patients undergoing cervical decompression surgery will be consented and enrolled if they meet the inclusion and exclusion criteria. Subsequently, incidence of C5P will be monitored to determine efficacy of prophylactic C5 bilateral foraminotomy during cervical decompression.
Spinal Cord Transcutaneous Stimulation Effect on Blood Pressure in Acute Spinal Cord Injury (SCI)...
Spinal Cord InjuriesSpinal Cord Diseases9 moreThe goal of this clinical trial is to evaluate the effect of transcutaneous spinal cord stimulation on blood pressure in individuals with an acute spinal cord injury (within 30 days of injury). Blood pressure instability, specifically orthostatic hypotension (a drop in blood pressure when moving lying flat on your back to an upright position), appears early after the injury and often significantly interferes with participation in the critical rehabilitation time period. The main questions it aims to answer are: Can optimal spinal stimulation increase blood pressure and resolve orthostatic symptoms (such as dizziness and nausea) when individuals undergo an orthostatic provocation (a sit-up test)? Optimal stimulation and sham stimulation (which is similar to a placebo treatment) will be compared. What are the various spinal sites and stimulation parameters that can be used to increase and stabilize blood pressure to the normal range of 110-120 mmHg? Participants will undergo orthostatic tests (lying on a bed that starts out flat and then moved into an upright seated position by raising the head of bed by 90° and dropping the base of the bed by 90° from the knee) with optimal and sham stimulation, and their blood pressure measurements will be evaluated and compared.
Patient Specific Template Guided Pedicle Instrumentation Versus Free Hand Technique
Spinal Cord DiseasesThe clinically already tested and approved MySpine system is compared to the free-hand dorsal instrumentation, which is the gold standard in spondylodesis surgery. The aim of this study is to investigate whether or not the pedicle screw can be inserted anatomically more accurately by the MySpine system than by the conventional free-hand method using intraoperative fluoroscopy.
Comparison of Transcutaneous and Epidural Spinal Stimulation for Improving Function
Spinal Cord InjuriesSpinal Cord Diseases5 moreIncomplete spinal cord injuries (SCI) are the most frequent neurologic category, comprising 66.7% of all SCI cases. People with incomplete SCI may retain some ability to move the legs and therefore the capacity to regain walking. Studies that show functional improvement in locomotion via electrical stimulation of lumbosacral circuits suggest that the underlying mechanisms are neuromodulation of lumbosacral spinal cord automaticity and sensory feedback. Both epidural and transcutaneous spinal stimulation are demonstrating exciting potential to improve limb function for people after chronic SCI. Available treatment options for SCI are less than satisfactory and most often do not achieve full restoration of function. Recent experimental results suggest an exciting new approach of using electrical spinal stimulation to enable users to regain control of their weak or paralyzed muscles. Using surgically-implanted electrodes, epidural stimulation results in remarkable improvements of lower extremity function as well as autonomic functions such as bladder function and sexual function. In addition to epidural stimulation, over only the last few years a novel strategy of skin surface electrical spinal stimulation has also demonstrated exciting potential for improving walking function. Using a high-frequency stimulation pulse, current can pass through the skin without discomfort and activate the spinal cord; this results in patterned stepping movements for people without SCI and improved lower extremity function following SCI. This study will directly compare skin-surface transcutaneous stimulation with implanted epidural stimulation for improving lower extremity function.
PAS in Subacute SCI
Spinal Cord InjuriesSpinal Cord DiseasesThe investigators have recently shown in incomplete SCI patients that long-term paired associative stimulation is capable of restoring voluntary control over some paralyzed muscles and enhancing motor output in the weak muscles. In this study, the investigators will administer long-term paired associative stimulation to patients with incomplete cervical level SCI at the subacute stage, and investigate its effectiveness for upper extremity rehabilitation.
Stem Cell Spinal Cord Injury Exoskeleton and Virtual Reality Treatment Study
Spinal Cord InjuriesSpinal Cord Compression9 moreThe SciExVR study will evaluate the potential benefit of autologous bone marrow derived stem cells (BMSC) in the treatment of spinal cord injury with evidence of impaired motor or sensory function. The treatment consists of bilateral paraspinal injections of the BMSC at the level of the injury as well as superior and inferior to that spinal segment followed by an intravenous injection and intranasal placement. Patients undergoing BMSC treatment may also be assigned to use of exoskeletal movement (or equivalent) or virtual reality visualization (or equivalent) to augment upper motor neuron firing and/or receptivity of the sensory neurons. http://mdstemcells.com/sciexvr/
