Ultrasound-guided quadratus lumborum block (QLB) is a fascial plane block where local anesthetic is injected adjacent to the quadratus lumborum muscle with the goal of anesthetizing the thoracolumbar nerves. In TLIP block, local anesthetic solution is injected between the multifidus and logissimus muscles nearly at the level of the 3rd lumbar vertebra and targets the dorsal rami of the thoracolumbar nerves. Ahiskalioglu et al. defined modified-lateral technique of TLIP (mTLIP) block as a new approach. Ahiskalioglu et al. have reported that this approach has some advantages. Firstly, sonographic visualisation is more easily than the classical technique. Secondly, insertion of the needle from medial to lateral direction reduces the risk of possible neuraxial injection. It has been reported that this technique provides effective analgesia after lumbar spinal surgery. The aim of this study is to compare US-guided mTLIP block and QLB for postoperative analgesia management after lumbar disc herniation-laminectomy surgery.
The prevalence of post-surgical lumbar neuropathic radiculopathy is approximately 30%. Poor response to the treatments recommended for neuropathic pain, namely antidepressants and/or gabapentinoids, requires the development of new techniques to prevent this chronic pain. Certain well-tolerated techniques, such as the administration of plasma enriched with platelets and fibrin (PRF), are increasingly used in regenerative medicine for their anti-inflammatory and analgesic properties. Thus, a periradicular intraoperative application of PRF may have an analgesic effect on the intensity of residual postsurgical neuropathic pain after disc herniation surgery.
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
The objective of this research study is to show whether data given by Oura ring could be used to objectively measure patients pain and well-being before and after disc surgery.
Intraoperative Neuromonitoring (IONM) is a tool used by neurophysiologists during spine surgery to prevent irreversible damage to the spinal cord during procedures through a system of alerts. This study investigates the effectiveness of IONM in 300 participants receiving spine surgery. The goal of this study is to refine the alert criteria for procedures in which IONM is used.
Comparison between Dynamic Cervical Implant as a recently introduced technique in our department and the conventional Anterior Cervical Discectomy and Fusion in management of single-level cervical disc prolapse.
Motor Evoked Potentials are an aspect of intraoperative neuromonitoring, a tool used by neurophysiologists during surgery to prevent irreversible damage to the spinal cord during procedures. This study investigates the utility of three separate quadriceps MEP recording approaches over a total of 40 limbs (20 participants).
The purpose of the this study to evaluate the feasibility, safety, and efficacy of a fluoroscopically-guided dorsal ramus block placed by the operative neurosurgeon prior to lumbosacral surgery. The study will consist of a retrospective analysis of a cohort of patients who underwent lumbosacral surgery patients between June 2018 and March 2021 with or without a preoperative fluoroscopically-guided dorsal ramus (DR) block placed by the operative neurosurgeon.
Transforaminal epidural steroid injection (TFESI) has been increasingly preferred in patients who can not benefit from conservative approach in the treatment of lumbosacral radiculopathic pain due to lumbar disc herniation. The aim of our study is to evaluate the effect of metabolic syndrome on the treatment results of transforaminal epidural steroid injection in patients with chronic radicular low back pain due to lumbar disc herniation.
