Filter by:The primary objective of this study is to measure the success rate of lumbar fusion in subjects at 12 months when instrumented lumbar arthrodesis is performed using OssiMend Bioactive Moldable as the bone grafting material
The aim of our study is to determine the superior procedure in analgesia management by comparing the traditional wound infiltration technique with the ultrasound-guided bilateral erector spina plan block technique in spinal surgery patients.
Rationale: Cervical degenerative disc disease (CDDD) is a common cause of cervical radiculopathy, myelopathy or myeloradiculopathy. Surgical treatment is indicated when conservative therapies do not provide sufficient relief or when neurological complaints are progressive. The main surgical techniques are anterior cervical discectomy with (ACDF) or without fusion (ACD), whereas both techniques result in high fusion rates. Short term outcomes of surgery show good clinical results. Long term follow-up shows a drop-in satisfaction rates, often due to the occurrence of new complaints. Pathology is often located at levels adjacent to the previously operated segment, known as adjacent segment disease (ASDis). This is thought to be the results of loss of motion at the previously operated and fused segment. Anterior cervical discectomy with arthroplasty (ACDA) is developed in an effort to reduce the incidence of ASDis by preserving physiological motion in the operated segment. Objective: To investigate physiological motion of the cervical spine the investigators will analyze motion patterns at the long-term in patients who underwent surgical treatment for CDDD, either ACD or ACDA. Study design: Fundamental research. This is a prospective study that includes a cohort of patients previously operated in the setting of a randomized controlled trial. Study population: Adult patients with an indication of surgical treatment for cervical radiculopathy as a consequence of CDDD were enrolled in an RCT between 2007 and 2014 and assigned to undergo ACD or ACDA. Flexion and extension cinematographic recordings of the cervical spine were performed, with the last one at one-year follow-up. The majority of patients in the ACDA group (80%) showed a normal sequence of segmental contribution, which was not the case in the ACD group. This cohort will now be asked to participate in the long-term follow-up study assessing the motion patterns 6-13 years after ACD or ACDA surgery. Intervention: One flexion and extension cinematographic recording of the cervical spine and will be made. Main study parameters/endpoints: The sequence of segmental contributions in sagittal rotation during flexion and extension of the cervical spine will be assessed in the long-term follow-up of surgical treatment. Secondary outcomes will be to assess the amount of degeneration based on the Kellgren Score (KS) and the segmental range of motion (sROM). Long term clinical outcomes will be assessed according to VAS, NDI, SF-36 and Odom's criteria. Patients will be asked whether they have new neurological symptoms and whether they have had a re-operation. Nature and extent of the burden and risks associated with participation, benefit and group relatedness: Participants receive cinematographic recordings once. The amount of radiation is a negligible risk. There will be no health benefits. There will be no follow-up.
The intention of the study is to investigate whether Deep Brain Stimulation (DBS) will improve postural deformities of patients with Parkinson's disease.
The rationale for multimodal analgesia is to achieve additive or synergistic analgesic properties while decreasing the incidence of side effects by reducing the dose of each agent. Nociceptive stimuli are known to activate the release of the excitatory amino acid glutamate in the dorsal horn of the spinal cord. The resultant activation of NMDA receptors causes calcium entry into the cell and triggers central sensitization. This mechanism is involved in the perception of pain and mainly accounts for its persistence during the postoperative period. Peri-incisional injection of local anesthetics is an effective method for pain relief after many surgical procedures, as it can reduce postoperative analgesic consumption. Ropivacaine is a propyl analog of bupivacaine with a longer duration of action with a much safer cardiotoxicity profile than bupivacaine. Thus, a combination of local anesthetic with other analgesic factors, such as opioids, dexmedetomidine, clonidine, ketamine, magnesium sulfate, dexamethasone is suggested for a better analgesic outcome. Dexmedetomidine, a highly selective a2-adrenergic receptor agonist, has been the focus of interest for its broad spectrum (sedative, analgesic, and anesthetic sparing) properties, making it a useful and safe adjunct in many clinical applications. The intravenous, intramuscular, intrathecal, epidural, and perineural use of this agent enhances analgesic effects. Tramadol hydrochloride is a synthetic analog of codeine that acts on both opioid (weak m receptor agonist) and nonopioid receptors (inhibits the reuptake of noradrenaline and serotonin as well as release stored serotonin from nerve endings) which play a crucial role in pain inhibition pathway. It also blocks nerve conduction which imparts its local anesthetics like action on peripheral nerves. It was reported that NMDA antagonists could prolong the analgesic effect of bupivacaine to even a week, as well as inhibit hyperalgesia. Magnesium sulfate (MGS) is a non-competitive antagonist of N-methyl, D-aspartate (NMDA) receptors with an analgesic effect and is essential for the release of acetylcholine from the presynaptic terminals and, similar to calcium channel blockers (CCB), can prevent the entry of calcium into the cell. Aim of the study is to evaluate and compare the postoperative analgesic efficacy of tramadol, dexmedetomidine, and magnesium when added to ropivacaine as an adjuvant for wound infiltration following spine surgery.
A global, prospective, non-randomized, multicenter, observational, post-market, medical record review registry evaluating real-world evidence for SeaSpine products.
EQ-5D is one of the most commonly employed patient-reported outcome (PRO) measures. It is included in many of the Swedish National Quality Registers (NQRs). EQ-5D health states are usually summarized using 'values' obtained from healthy members of the general public. However an alternative - which remains to be studied in detail - is the potential to use patients' self-reported overall health on the visual analogue scale as a means of capturing experience-based values. The overall aim of this project is to increase knowledge on the potential applicability of EQ VAS as a health state valuation method through assessment of its variability across and within patient groups and compared with that of the general population in Sweden. Data on nearly 700,000 patients from 12 NQRs covering a variety of diseases/conditions and from the general population will be analysed. Longitudinal studies of PROs among different patient groups will be conducted at baseline/first visit and 1-year follow-up. Descriptive analyses comparing EQ-5D health states and observed self-assessed EQ VAS within and across registers will be performed. Comparisons of the change in health state and observed EQ VAS values over one year will also be made. Regression models will be used to assess whether EQ-5D dimensions predict observed EQ VAS values to investigate patient value sets in each NQR. These will be compared across the patient groups and with the existing Swedish experience-based VAS and time trade-off (TTO) value sets obtained from the general population. This research project will provide information on the variation among different patient groups in terms of self-reported health status through EQ VAS and comparison with the general population. Knowledge on the relative importance of different dimensions of the EQ-5D to different patient groups as well as the general population will be gained in this project. The possibility of getting value sets based on patients' self-reported EQ VAS values and their comparison with value sets from experience-based general population studies will be discussed.
