Active clinical trials for "Intervertebral Disc Displacement"

In this clinical trial, equivalence is evaluated by exploratory comparison of changes in X-Ray lesions with test group (Cerazem Master V6) and control group (physical therapy) in patients with intervertebral disc herniation and degenerative stenosis.

Rationale: Lumbar spine surgery is associated with high postoperative pain scores and analgesic use, despite use of multimodal analgesia. The erector spinae plane block (ESPB) is a promising locoregional anesthetic technique for this type of surgery. The literature is not yet conclusive about the effectiveness of this technique on reducing postoperative pain intensity. Objective: The objective of this study is to evaluate the analgesic effect of ESPB as add-on therapy to multimodal analgesia on early postoperative pain intensity after lumbar spinal fusion surgery compared to placebo. Study design: The study is designed as a prospective mono-centre, randomized, double-blinded, placebo-controlled trial. Study population: 76 patients ≥ 18 years of age requiring elective lumbar spinal fusion surgery involving one to four fusion levels. Intervention: Patients will receive ultrasound-guided ESPB with either ropivacaine or placebo at the end of surgery. Main study parameters/endpoints: Main study parameter is pain intensity upon emergence from anesthesia measured with the Numeric Rating Scale. A minimal clinically important difference is considered to be a decrease of 1.5 points. Secondary endpoints are pain intensity during hospital stay and after 30 days, opioid use during hospital stay and after 30 days, opioid side effects, use of anti-emetics, time to first opioid use/request, length of hospital stay, quality of recovery at discharge. Nature and extent of the burden and risks associated with participation, benefit and group relatedness: The Sint Maartenskliniek is experienced in applying locoregional analgesia, the use of ropivacaine and using sonography. The procedure of administering ESPB has a very low risk of complications. Receiving placebo is justifiable because this group will not be withhold standard treatment. The risks of receiving placebo are negligible. The patients will visit the clinic at regular follow-up moments.

The purpose of this study is to determine a grading system for inflammation in lumbar disc herniation and which groups, if any, benefit most from the administration of an intra-operative epidural steroid.

The goal of this randomized clinical trial is to investigate whether modified enhanced recovery after surgery (ERAS) in oblique lumbar interbody fusion (OLIF) can shorten the postoperative hospital stay among patients with lumbar degenerative disease. The main questions it aims to answer are: Whether ERAS can shorten the postoperative hospital stay. Whether modified ERAS can improve postoperative functional recovery, improve functional score and pain score, reduce hospitalization costs, improve mental state, and improve abdominal indicators, etc. Participants will be randomized into modified ERAS group, or control group.

The regional methods of anesthesia for the neurosurgical operations of the spine and spinal cord reducing the needs for opioids intra operatively and reducing pain in the postoperative period, decrease the numbers of failed back syndrome.

Chronic lumbar radicular (CLR) pain is a term used to describe neuropathic pain symptoms in the distribution of a particular lumbar nerve root due to disc protrusion, spinal stenosis, facet hypertrophy, or fibrosis after previous surgery. The pathophysiology of CLR pain involves mechanical, inflammatory, and immunologic factors that affect the function of the dorsal root ganglion (DRG).1Treatment methods include oral pain medications, physical therapy, epidural steroid injection (ESI) and surgery. 2,3. Pulsed radiofrequency (PRF) was developed as a modification of the well-known radiofrequency ablation treatment. In conventional radiofrequency ablation, a high frequency alternating current is used to produce coagulative necrosis of the target nerve tissue without any selectivity for nociceptive fibers. However, in PRF, a current in short (20 msec) high voltage bursts is followed by silent phases (480 msec) which allow for heat dissemination, keeping the target tissue controlled below 42°C. 4,5 The mechanisms via which PRF causes analgesia are still not clearly understood, but laboratory experiments have highlighted some possible ways in which it might act, including its effects on neuropathic pain. Clinical use of PRF has been expanding, despite there being limited evidence of clinical efficacy in the form of randomized controlled trials (RCTs). 6 There have been few RCTs using PRF-DRG for radicular pain. Van Zundert et al performed an RCT in subjects with cervical radicular pain.7 Simopoulos et al did a pilot study on lumbar radicular pain, but the methodology included application of conventional radiofrequency over PRF in the study group and was not an efficacy trial. As such, the efficacy of PRF-DRG in CLR has never been determined. 8 Neuroplasticity or neuronal plasticity refers to the ability of the nervous system to do neuronal remodeling, formation of novel synapses and birth of new neurons. Neuronal plasticity is intimately linked to cellular responsiveness and may therefore be considered an index of the neuronal capability to restore its function. Failure of such mechanisms might enhance the susceptibility to neuronal injury.9 Neurotrophic factors (NTFs), and in particular the neurotrophin family, play an important role. In fact, besides their classical role in supporting neuronal survival, NTFs finely modulate all the crucial steps of network construction, from neuronal migration to experience-dependent refinement of local connections. It is now well established that NTFs are important mediators of neuronal plasticity also in adulthood where they modulate axonal and dendritic growth and remodeling, membrane receptor trafficking, neurotransmitter release, synapse formation and function.10 The neurotrophin brain-derived neurotrophic factor (BDNF) has emerged as crucial mediator of neuronal plasticity, suggesting that it might indeed bridge experience with enduring change in neuronal function.11BDNF acts on certain neurons of the central nervous system and the peripheral nervous system, helping to support survival of existing neurons, and encouraging growth and differentiation of new neurons and synapses.12,13 S100B belongs to the family ofcalcium binding proteins, is expressed mainly by astrocytesand is found both intra- and extracellularly in brain tissue. It was also reported that mature myelinating and non-myelinating Schwann cells of peripheral nerves strongly display S100 protein immunoreactivity (Stefansson et al., 1982; Sugimura et al., 1989; Vega et al., 1996).14 S100B can spill from injured cells and enter the extracellular space or bloodstream. Serum levels of S100B increase in patients with neuronal damage. Over the last decade, S100B has emerged as a candidate peripheral biomarker of neuronal injury. Elevated S100B levels accurately reflect the presence ofneurodegenerayion. Its potential clinical use in the therapeutic decisions is substantiated by a vast body of literature. Thus, the major advantage of using S100B is that its elevatio in serum provides a sensitive measure for determining neuronal injury at the molecular level before gross changes level.15

In endoscopic spinal nerve root decompression surgery, the intraoperative nerve exploration is time-consuming and critical. According to statistics, the incidence of nerve root injury under spinal endoscope is 1.8-2.5%. Damage to nerve roots may lead to postoperative sensory retardation and motor weakness, thereby impairing the physical function of patients. A real-time auxiliary intraoperative nerve identification technology is necessary. In this prospective, open-label, randomized, parallel controlled trial, 40 patients who undergo endoscopic spinal surgery are included. Subjects are randomly divided into control group and low, medium and high Indocyanine green(ICG) preoperative administration experimental group. Standard endoscopic spinal surgery is performed in the control group. Patients in the experimental group received an intravenous injection of ICG before surgery, and a standard endoscopic spinal surgery is performed with the use of a fluoroscopic endoscopic surgical imaging system to assist the surgeon in identifying and protecting the nerve roots. The main objectives of this experiment are (i) to explore the safety and feasibility of ICG fluorescence imaging to assist in nerve root identification during endoscopic spinal surgery and (ii) the effectiveness of this technique for endoscopic search for nerve roots. The secondary objective is to explore the optimal ICG dosing regimen.

The goal of this clinical investigation is to learn about DISC Care, an Hernia Blocking System, in patients who have undergone lumbar disc hernia surgery. The main questions it aims to answer are: if the implant (DISC Care) prevents disc herniation recurrence if DISC Care is a safe device Participants will be implanted with DISC Care and followed up for two years (7 visits).

The purpose of this study is to determine the optimal anesthetic routine for lumbar decompression surgery. General Anesthesia is the standard of care in spine surgery. Spinal anesthesia in decompressive procedures can be the new standard of care. Recently, it has been found that regional analgesia is option that has been shown to improve pain and opioid-related outcomes after spine surgery, but has not yet been studied in combination with spinal anesthesia. This is study that consists of two groups: standard of care general anesthesia with a nerve block and a spinal anesthesia with nerve block. Patients are randomized to either of the two groups. There will be 71 patients enrolled in each group for this study.

This is a prospective, single arm clinical study to evaluate fusion status and patient reported outcomes utilizing the Stryker Tritanium® C Anterior Cervical interbody device at one or two contiguous levels. Subjects that are recommended for surgical treatment of either a 1- or 2-level ACDF (Anterior Cervical Discectomy and Fusion) between the levels of Cervical Spine 2 to Thoracic 1 (C2-T1) and diagnosed with degenerative disc disease will be screened for the study.
