Active clinical trials for "Spinal Cord Diseases"

This study intends to establish a multidisciplinary collaborative ERAS clinical pathway of cervical posterior surgery,and to verify its effectiveness, safety and value in health economics.

Utilization of T2* MRI in predicting prognosis in patients with cervical spondylotic myelopathy (CSM)

DESIGN: Ambispective cohort study (retrospective + prospective). AIMS: The overall aim of this research study is to create two predictive machine learning models that are based on radiological, clinical and biochemical variables, which allows spine surgeons to diagnose CSM earlier and more accurately, as well as allowing them to give patients highly individualised and accurate predictive information regarding treatment outcomes. OUTCOME MEASURES: For the prospective arm of the study the independent variables will be patient characteristics, clinical, radiological and biochemical markers. Dependent variables are mJOA and JOACMEQ scores. For the retrospective arm of the study the independent variables will be patient characteristics, co-morbidities and symptomology, outcome variable will be radiological confirmation on cervical myelopathy. POPULATION: Patients with cervical myelopathy over 18 years old (19 years and above included), treated at Imperial College NHS Healthcare Trust for CM with full capacity to consent and assessed for cervical myelopathy symptoms at Community MSK Hounslow and Richmond Community Healthcare NHS Trust (catchment area of ICHT neurosurgery). ELIGIBILITY: Over 18 years old, with full capacity to consent. TREATMENT: Cervical myelopathy diagnosis and/or conservative and/or surgical management of disease DURATION: 18 months

This research study is being conducted to help improve the pre-operative, intra-operative, and post-operative course for patients and enhance recovery.

The study will consist of two parts: In Study A, objectively assessed physical activity, gait, balance, range of movement of specific joints during walking and neurophysiological findings between patients with cervical spine stenosis (CSS) without myelopathy who will be treated conservatively and patients with stenosis and signs of myelopathy who are candidates for surgical Treatment will be compared. In Study B, the 6-month changes in the same outcomes in patients treated conservatively (from the first specialist consultation until 6 months later) and in patients treated surgically (preoperative day and 6-month post-operatively) will be quantified.

The purpose of this study is: To assess the validity and reproducibility of the MP Diagnostics HTLV Blot 2.4. To conduct a sensitivity analysis of the HTLV Blot 2.4 using a known positive population.

Cervical degenerative disease is an almost universal concomitant of human aging. Over half of the middle aged population has cervical spondylosis. This condition is often asymptomatic, but in 10% to 15% of the cases, it is associated with, or progresses to, neural compression. Cervical spondylotic radiculopathy is a condition due to a root nerve compression while cervical spondylotic myelopathy is a condition due to a medullar cord compression. Root nerve or medullar cord can be compressed either by a soft disc extrusion or by arthrosis due to a degenerative disc. Anterior cervical discectomy and fusion is the standard surgical treatment of the cervical radiculopathy or cervical myelopathy when non-surgical treatment failed. The aim of this surgery is to provide a neurologic decompression associated to spine stabilization. Decompression is achieved by removal the disc and soft disc extrusion if present. Stabilization is supported by implantation of material in the interbody space like bone or cage with bone substitute. This cage provides a bone fusion matrix and an intervertebral height and stability support at the same time. To enforce the stabilization, a plate can be screwed on the anterior cervical vertebral wall. The HRCC® cage is a stand-alone cage with two rotary blades which penetrate into vertebral bone so there is no need to implant plate. One of the reasons why treatment can fail is the pseudarthrosis that is fusion failure. It mays occur as an increase of axial pain or radicular pain. The aim of this study is to demonstrate similar results on bone fusion in the surgical treatment of cervical radiculopathy or myelopathy with HRCC cage used in anterior cervical discectomy and fusion compared with other technics based on a prospective cohort study and a literature review. As secondary outcomes we will search to correlate pseudarthrosis and quality of life impact, to identify complications and to describe the sagittal balance evolution of the cervical spine. To this end, in the context of standard practices, patients who consult the neurosurgical team of the REIMS University Hospital Center with a diagnosis of a cervical radiculopathy or myelopathy with non-surgical treatment failure needing a one level anterior cervical discectomy and fusion will be proposed to be included during this pre-operative consultation. There will be pre-operative collected data about demographic data, pseudarthrosis risk factors, pre-operative symptomatology, quality of life data and pre-operative imagery data. Per-operative and hospitalization data are collected as well with surgery duration, blood lost, surgical technic, pain measurement and hospitalization duration. Next, follow-up starts with consultations at 6 weeks, 6 months and 12 months and pain, quality of life and classic X-Ray data are collected to be compared with pre-operative data. And Imagery data are collected in order to identify presence or absence of pseudarthrosis with dynamic X-Ray and CT-scan at 6 months and 12 months. A statistical analysis of the data is next performed to found significant results.

Myelopathy describes any neurologic deficit related to the spinal cord. Myelopathy is caused by various pathological states of the human spinal cord, including tumors, inflammatory lesions, spinal cord compression and degenerative myelopathy. Clinically, the diagnosis of myelopathy depends on localization of the neurologic finding to the spinal cord, rather than the brain or peripheral nervous system and then to a particular segment of the spinal cord. Magnetic resonance imaging (MRI) plays an essential role in the diagnosis and follow-up of the lesions of the spinal cord using conventional MRI T1- and T2-weighted sequences. Sometimes a studied spinal cord may appear normal on conventional MRI even though patients have symptoms of myelopathy causing a discrepancy between MRI findings and clinical findings. Diffusion tensor imaging (DTI) is an advanced non-invasive MR imaging technique which assesses the microstructural integrity of nerve fiber tracts.

Hypotheses: Decompressive surgery of cervical myelopathy will improve bladder function. Decompressive surgery of cervical myelopathy will improve sexual function.
