Filter by:Objectives: Musculoskeletal problems have been a concern in dentists for years. The aim of this study is to evaluate the relationship between posture and musculoskeletal pain in dentists.
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.
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').
Multicenter Post market clinical follow-up Study on the Safety and Performance of Ennovate® Cervical - Prospective, pure data collection of all Ennovate Cervical patients in Total Indications
This study is a prospective, multi-center, open label registry designed to collect real-world data on performance and safety data on RTI's spine products.
This is a multi-center, post-market, retrospective study design to collect safety and performance data for patients implanted with the Streamline OCT System.
Extended arthrodesis of the spine is indicated in the treatment of deformities. The principle of the intervention is to correct the spinal imbalance and to obtain a fusion of the vertebral segment operated in order to guarantee the durability of this correction, in order to guarantee a functional result the best possible one. There is a great disparity in the techniques available to obtain this result: as regards the correction of the deformation itself, it is possible to resort to various types of gestures aimed at "freeing" the spine to allow the getting the correction. It may be staged or transpedicular osteotomies or previous releases (staged discectomies). Regarding the arthrodesis itself, this can be obtained by an isolated posterior graft or by a circumferential graft itself performed in a time using interbody cages PLIF type (posterior lumbar interbody fusion) or TLIF (transforaminal interbody fusion) or in two stages by a complementary anterior graft. These are heavy interventions with a high complication rate. The choice of this or that technique is based on data from the literature and remains at the discretion of the surgeon who makes the surgical indication. However, it has never been possible to compare these different techniques in a prospective study. The few articles comparing the different techniques tend to show that there is no significant difference between the techniques with a higher complication rate for the two-step techniques. However, these are retrospective studies, with all the biases that this implies and despite these results the disparity in surgical indications remains substantial. The objective of this work is therefore to evaluate, according to an identical protocol, the different surgical techniques for the treatment of spinal deformities associated with a fusion in order to determine the morbidity associated with each of the techniques and if this morbidity is justified by a better functional result at a minimum follow-up of two years.
Readmissions increasingly serve as a metric of hospital performance, inviting quality improvement initiatives in both medicine and surgery. Recently, a readmission reduction program in the United States was associated with significantly shorter length of stay, earlier discharge, and reduced 30-day readmission after elective neurosurgery. These results underscore the importance of patient education and surveillance after hospital discharge, and it would be beneficial to test whether the same approach yields beneficial results in a different health system, the NHS. In this study, the investigators will replicate the Transitional Care Program (TCP) published by Robertson et al.(Journal of Neurosurgery 2017) with the goal of decreasing length of stay, improving discharge efficiency, and reducing readmissions in neurosurgical patients by optimizing patient education and post-discharge surveillance.
The five-repetition sit-to-stand test has been validated and is used primarily in pulmonary medicine and cardiology, and has recently been shown to be a useful tool for the objective assessment of functional impairment in patients with degenerative diseases of the lumbar spine. The goal of this study is to assess the possibility of supervised and unsupervised at-home-assessment. Validation of at-home-assessment would allow the 5R-STS to be easily used as a follow-up tool in clinical trials, for example.
Patients with degenerative lumbar spondylolisthesis usually are present with low back pain, muscle spasm and weakness, radicular symptoms, intermittent claudication, insomnia, even urine or stool incontinence. There are very few research on the effectiveness of core spine stabilization exercise, balance training, and the balance effect while wearing lumbar corset in these patients. Purpose: To investigate 1) the correlation of dynamic balance and the degree of disability with the characteristics of spinopelvic alignment. 2) potential predictors of dynamic spino-pelvic instability, 3) the effectiveness of core spine stabilization exercise, balance training and balance effect of the wearing of lumbar corset in patients with degenerative lumbar spondylolisthesis .
