Background Chronic low back pain is the most prevalent chronic condition worldwide and access to behavioral treatment limited. Virtual reality (VR) an immersive technology that may provide effective therapeutics for pain. Objective We aimed conduct a double-blind, parallel-arm, single-cohort, remote, randomized placebo-controlled trial self-administered skills-based VR program in community-based individuals with self-reported during COVID-19 pandemic. Methods A national online convenience...
Abstract Proper anesthesia and knowledge of the anatomical location iliohypogastric ilioinguinal nerves is important during hernia repair other surgical procedures. Surgical complications have also implicated these nerves, emphasizing importance development a clear topographical map for use in their identification. The aim this study was to explore variations relate information clinical situations. One hundred adult formalin fixed cadavers were dissected resulting 200 nerve specimens. Each...
The object of this study was to compare surgical outcomes and complications in a contemporaneous series patients undergoing either microscopic or endoscopic transsphenoidal surgery for nonfunctioning pituitary macroadenomas without imaging evidence cavernous sinus invasion.This is retrospective analysis prospectively collected database from single institution. Data were whose had occurred the period June 2010 January 2013. Patients who underwent Knosp Grade 0, 1, 2 included study. clinically...
Myocardial bridging is recognized as an anatomical variation of the human coronary circulation in which epicardial artery lies myocardium for part its course. Thus, vessel 'bridged' by myocardium. The anterior interventricular branch left has been reported most common site myocardial bridges but other locations have reported. purpose this study was to provide more definitive information on vessels with bridges, length and depth bridged segment, relationship between presence dominance. Two...
Recent reports emphasize the importance of preserving intercostobrachial nerve (ICBN) during surgical procedures (i.e., mastectomy, axillary clearance). However, a limited number scientific explore anatomy this nerve. We dissected 100 adult human formalin-fixed cadavers (200 axillae). In all ICBN was present with variant contributions from intercostal nerves T1, T2, T3, and T4. The arrangements were typed as I through VIII. components Type (45% or 90 our specimens) included branch to...
Abstract With recent laparoscopic advancements in retroperitoneal and thoracic surgical procedures, familiarity with major lymphatic structures, such as including the cisterna chyli (CC) duct (TD), has proven beneficial avoiding misdiagnosis iatrogenic intraoperative injury. In this light, aim of our study was to explore delineate topography CC, classify different patterns tributaries, categorize its varying location respect vertebral bodies. The anatomy CC examined 120 adult human cadavers....
Virtual reality (VR) allows for presurgical planning. Intraoperatively, augmented (AR) enables integration of segmented anatomic information with neuronavigation into the microsurgical scene to provide guidance without workflow disruption. Combining VR and AR solutions may help guide technique improve safety, efficiency, ergonomics.To describe a VR/AR platform that provides planning intraoperative via microscope ocular injection comprehensive overlay patient-specific 360°/3D model aligned...
OBJECTIVE Augmented reality (AR) has the potential to improve accuracy and efficiency of instrumentation placement in spinal fusion surgery, increasing patient safety outcomes, optimizing ergonomics surgical suite, ultimately lowering procedural costs. The authors sought describe use a commercial prototype Spine AR platform (SpineAR) that provides head-mounted display (ARHMD) user interface for navigation-guided spine surgery incorporating real-time navigation images from intraoperative...

The superior and inferior sagittal sinuses have been well studied. Interestingly, other venous structures within the falx cerebri received scant attention in medical literature. present study was performed to elucidate presence anatomy of these midline structures.The authors examined 27 adult latex- or ink-injected cadaveric specimens observe morphological features (excluding sinuses).All were found an extensive network small tributaries that primarily concentrated its posterior one third....
Background We previously reported the efficacy of an 8-week home-based therapeutic immersive virtual reality (VR) program in a double-blind randomized placebo-controlled study. Community-based adults with self-reported chronic low back pain were 1:1 to receive either (1) 56-day relief skills VR (EaseVRx) or (2) sham program. Immediate posttreatment results revealed superiority over for reducing intensity; pain-related interference activity, mood, and stress (but not sleep); physical...
There is considerable inconsistency in the description of origins, dimensions, and course recurrent artery Heubner (RAH). The RAH frequently supplies parts basal ganglia anterior limb internal capsule can be damaged with improper clip placement during repair aneurysms near communicating artery. Thus, further elaboration anatomical descriptions necessary. gross anatomy was studied 69 human brain hemispheres. found as a single vessel 53 hemispheres (77%), double arteries 12 (17%), absent 4...
False tendons (FTs) have been extensively described and recognized by gross anatomic studies. However, in the clinical setting recognition of FTs is limited to use echocardiography. We examined 200 formalin fixed adult hearts, with dissections. In addition, 90 these specimens were also ultrasonographic endoscopic techniques. Gross examination was able identify 128 (62%) specimens. The total number observed, 248 classified into five types according their location. Type I (92, 37.1%) FT...
Although Crooke's changes in the pituitary corticotrophs were initially described 1935, prevalence which occur patients with Cushing's syndrome (CS) has not been established.This study aimed to determine and assess clinical features associated presence or absence of a large set CS.Information from prospective computer database retrospective chart review was analyzed.The setting an academic medical center.Consecutive (N = 213) who received surgery preoperative diagnosis disease are...
Traditional approaches to medial temporo-occipital intra-axial brain tumors carry the risk of visual or language deficits related retraction transgression deep fiber tracts. To reduce these risks, microscopic supracerebellar transtentorial approach with patient in sitting position has been previously described for lesions relative proximity tentorium.We describe this performed endoscopic tumor resection allow better visualization and a more ergonomic operating position.Four consecutive...
