Filter by:This study aims to determine to what extent patient-specific factors, iatrogenic factors, and biomechanical factors influence cervical spine mechanics after single-level and two-level arthrodesis.
Purpose: The incidence of surgery for Degenerative lumbar Disc Disease (DDD). According to the national spine registries in Sweden, Norway and Denmark, there is a difference in surgical incidence between these countries. The cause for this difference is not known. It may reflect a difference in incidence of lumbar disc hernia, but with a similar socio-economic and ethnical background in these countries, it is more likely that the differences are due to varying surgical indications. Comparing indications for surgery, patient reported outcome and factors predictive for outcome after surgery for lumbar disc decease in these countries could provide information about optimal indications for surgery. Hypotheses: (i) there are no differences in patient-reported outcome after surgery between these countries, (ii) there are no differences in indications for surgery between these countries and (iii), factors that predict outcome are similar in these countries. Method of research: By using data from three Nordic national spine registers, investigators will compare baseline data, indications for surgery and patient reported outcome one year after surgery for lumbar disc decease. Register based studies have advantages such as large sample sizes, reflecting real life, but they also have limitations such as lower follow-up rates than clinical trials. A non-response analysis will be performed to take this into account.
This prospective, post-market, open label clinical study is designed to examine the lumbar fusion rate at 24 months post operative in subjects who have undergone a lumbar fusion surgery using Trinity Elite with or without local bone.
This Post Market Clinical Follow-up (PMCF) is conducted to collect clinical and radiographic outcome information on patients suffering from intractable symptomatic cervical disc disease requiring 1- or 2-level reconstruction of the disc from C3-C7, after being treated with the Triadyme-C polycrystalline diamond compact cervical disc replacement.
The study is a prospective non-randomized multi-center feasibility clinical trial to establish the safety and efficacy of the Nucel® allograft tissue for use in lumbar interbody fusion procedures.
The purpose of this study is - to evaluate the effectiveness of MAST techniques for anterior/lateral and posterior approaches in Degenerative Disc Disease (DDD) patients with spondylolisthesis (≥ grade I). - To assess how single or double level MAST(Minimal Access Spinal Technologies) fusion procedures PLIF (Posterior Lumbar Interbody Fusion), TLIF (Transforaminal Lumbar Interbody Fusion), DLIF (Direct Lateral Interbody Fusion), OLIF (Oblique Lumbar Interbody Fusion), ALIF (Anterior Lumbar Interbody Fusion), or MIDLF (Midline Lumbar Interbody Fusion) are used in surgical practice and to describe long-term safety and effectiveness in a broad patient population of patients with degenerative lumbar disc disease .
This study is a single-center, prospective randomized clinical study intended to compare and evaluate the efficacy of subjects who are treated with bone marrow aspirate concentrate (BMAC) and allograft to iliac crest bone grafts (ICBG) during posterior lumbar/lumbosacral spinal fusion.
The purpose of this study is to determine the relation among: (1) changes in voltage and amplitude of trans-operatory records obtained through the use of Intra-operative Neurophysiological Monitoring (IONM), and (2) clinical outcomes; of patients who underwent 1 or 2 levels surgical decompression at lumbar spine. IONM is the use of real time neurophysiological techniques during spinal surgeries. The modalities included in this study are: - Somatosensory evoked potentials (SSEPs). - Trans-cranial electric motor evoked potentials (tceMEPs). - Spontaneous electromyography (EMG). Clinical outcome of the patients will be assessed through a careful evaluation of clinical data, as well as the application of three outcome scales: - Oswestry Disability Index 2.1a - Visual Analogue Scale for Pain - Patient's Overall Impression of Change
This study will collect clinical and radiographic data on the Freedom Cervical Disc to monitor the device's safety and performance as part of a post-market evaluation.
The purpose of the research is to collect and examine spinal disc and ligament tissues to see if there are any biological markers that can be correlated with MRI images to help us learn more about causes of back pain. Spinal discs are the pillow-like cushions between the bones of the spine. They act as shock-absorbers for the spine. Spinal ligaments support the disc structure during movement.
