A Prospective Single-center Pilot Study on the Use of Closed-loop Spinal Cord Stimulation to Treat Chronic Pain Associated With Raynaud's Phenomenon.

Objectives: Raynaud's phenomenon (RP) is a vascular disorder characterized by episodic peripheral artery vasospasms, resulting in paleness, cyanosis, and/or erythema. There are few reports, mostly case reports, on the benefits of spinal cord stimulation (SCS) for the treatment of RP. However, there is a lack of objective evidence on SCS-induced modulation of the sympathetic system (eg, vasodilation) in this condition.

Fatal Subarachnoid Hemorrhage in a Deep Brain Stimulation Patient: Displacement of Stimulation Leads for Deep Brain Stimulation Indicate Subarachnoid Hemorrhage on X-ray.

We depict the rare case of a patient with aneurysmatic subarachnoid hemorrhage previously treated with deep brain stimulation for Parkinson's disease. Initial CT scans showed a Fisher grade 4 subarachnoid hemorrhage with lead displacement due to midline-shift. CT angiogram revealed a supra-ophthalmic aneurysm of the internal carotid artery.

[Functional-neurosurgical treatment options for functional pelvic floor disorders : Value of sacral neuromodulation].

Background: Sacral neuromodulation is an established minimally invasive therapy indicated for the treatment of functional pelvic floor disorders. While it received its original US Food and Drug Administration (FDA) approval for the treatment of overactive bladder symptoms, it is now regarded as a therapeutic option to treat both urinary/fecal incontinence and retention. In addition, it has proven to be a valuable tool in the treatment of chronic pelvic pain, and preliminary results indicate a potential to elicit improvements in sexual functioning.

Initial study on an expert system for spine diseases screening using inertial measurement unit.

In recent times, widely understood spine diseases have advanced to one of the most urgetn problems where quick diagnosis and treatment are needed. To diagnose its specifics (e.g.

Patient Safety Comparison of Frameless and Frame-Based Stereotactic Navigation for Brain Biopsy-A Single Center Cohort Study.

Leksell stereotactic system-based aspiration biopsy is a common procedure in the neurosurgical treatment of deep-seated or multiple brain lesions. This study aimed to evaluate the benefit of frameless biopsy using VarioGuide compared to frame-based biopsy using the Leksell stereotactic system (LSS). We analyzed all brain biopsies using VarioGuide or LSS at our neurooncological Department of Neurosurgery in the University Hospital of Bonn between January 2018 and August 2020.

Safety Evaluation of Cervical Dorsal Instrumentation in Geriatric Patients: Experience at a Level 1 Center for Spinal Surgery-A Single Center Cohort Study.

Objective: Dorsal instrumentation of the cervical spine is an established treatment in spine surgery. However, careful planning is required, particularly in elderly patients. This study evaluates early clinical outcomes in geriatric patients undergoing complex spine surgery.

Cervical epidural abscess due to implantation of a spinal cord stimulation lead.

Spinal cord stimulation (SCS) for intractable pain syndromes has become a pillar of modern pain management. Common complications include lead migration, implant infection, cerebral spinal fluid leak, and lead fracture. Spinal epidural abscess due to spinal cord stimulator implantation is a very rare occurrence with only two cases reported in the literature so far.

Bipolar Lumbar Radiofrequency Medial Branch Neurotomy in a Patient with Deep Brain Stimulation Implant.

Chronic axial lower back pain is one of the most common conditions that patients seek medical attention for in pain practices. About 15 to 40% of axial lower back pain is due to facet-mediated pain. Diagnostic blocks of the medial branch reliably identify the facet joint as the pain generator and offer a prognostic factor for response to radiofrequency neurotomy of the identified facet joints resulting in profound pain relief.

Endoscopic Lateral Approach for Dorsal Root Ganglion Burst Stimulation: Technical Note and Illustrative Case Series.

Introduction: Dorsal root ganglion (DRG) stimulation demonstrated superiority over traditional spinal cord stimulation with better pain relief and greater improvement of quality of life. However, leads specifically designed for DRG stimulation are difficult to implant in patients who previously underwent spinal surgery and show epidural scarring at the desired site of implantation because of the reduced stiffness of the lead. Nevertheless, recurrent leg or arm pain after spinal surgery usually manifests as a single level radiculopathy, which should theoretically be amenable to DRG stimulation.

Antithrombotic Therapy in Spinal Surgery Does Not Impact Patient Safety-A Single Center Cohort Study.

Objective: Antithrombotic therapy is common in older patients to avoid thromboembolic events. Careful planning is required, particularly in the perioperative environment. There are no clearly date guidelines on the best timing for interrupting the use of anticoagulation in the case of spinal surgery.

Indications for early revision surgery for material failure in spinal instrumentation: experience at a level 1 center for spinal surgery - a single-center study.

Posterior instrumentation is an established treatment for a range of spinal disorders. Material failure is not uncommon, and the indications for a revision are very heterogeneous. This study aimed to evaluate the indications and timing for early revision spinal surgery due to material failure.

Placement of Surgical Spinal Cord Stimulation Leads Using Spinal Process Splitting Laminotomy: Technical Note.

Objective: Spinal cord stimulation has become an established method within the therapy of chronic pain allowing for significant pain relief. Surgical leads usually must be implanted via a surgical procedure involving unilateral or bilateral muscle detachment and partial laminectomy.

Methods: We present the application of a novel minimal invasive microsurgical approach for lead placement, which combines the beneficial advantages of anatomic midline lead placement while preserving the midline structures, avoiding muscle detachments, and thus ensuring spinal stability: spinal process splitting laminotomy.

Can neuromodulation support the fight against the COVID19 pandemic? Transcutaneous non-invasive vagal nerve stimulation as a potential targeted treatment of fulminant acute respiratory distress syndrome.

The COVID-19 pandemic has rapidly spread all over the world and caused a major health care crisis. About 20% of patients develop severe disease and require hospitalisation, which is associated with a high mortality rate of up to 97% in those being ventilated and respiratory failure being the leading cause of death. Despite many therapeutic agents being under current investigation there is yet no panacea available.

A prospective, randomised, double-blind, placebo-controlled study to examine the effectiveness of burst spinal cord stimulation patterns for the treatment of failed back surgery syndrome.

Objectives: Spinal cord stimulation (SCS) for the treatment of chronic pain is a well-established therapy. However, the requirement that paresthesia be continually felt by the patient has important downsides. This study evaluated the effectiveness of a new paresthesia-free SCS paradigm, called burst stimulation, for the treatment of failed back surgery syndrome (FBSS) with a prospective, randomized, double-blind, placebo-controlled design.
