Radiation Exposure Analysis on 274 Patients With Vertebral Augmentation Using the Surgivisio Intraoperative Navigation System.

Background: Surgeons' reliance on intraoperative fluoroscopy during vertebroplasty procedures has raised concerns regarding the level of patient and surgeon radiation. Navigation systems have shown a potential to reduce the overall patient and medical staff exposure during dose exposure studies. The main objective of this study was to determine whether the Surgivisio platform (eCential Robotics, France), a unified imaging and navigation platform, lowers the patient dose during routine clinical usage as compared with published fluoroscopy and other navigation options that are published in the literature.

A Novel Application of Deep Learning (Convolutional Neural Network) for Traumatic Spinal Cord Injury Classification Using Automatically Learned Features of EMG Signal.

In this study, a traumatic spinal cord injury (TSCI) classification system is proposed using a convolutional neural network (CNN) technique with automatically learned features from electromyography (EMG) signals for a non-human primate (NHP) model. A comparison between the proposed classification system and a classical classification method (-nearest neighbors, NN) is also presented. Developing such an NHP model with a suitable assessment tool (i.

Neurophysiological Characterization of a Non-Human Primate Model of Traumatic Spinal Cord Injury Utilizing Fine-Wire EMG Electrodes.

This study aims to characterize traumatic spinal cord injury (TSCI) neurophysiologically using an intramuscular fine-wire electromyography (EMG) electrode pair. EMG data were collected from an agonist-antagonist pair of tail muscles of Macaca fasicularis, pre- and post-lesion, and for a treatment and control group. The EMG signals were decomposed into multi-resolution subsets using wavelet transforms (WT), then the relative power (RP) was calculated for each individual reconstructed EMG sub-band.

Model of Traumatic Spinal Cord Injury for Evaluating Pharmacologic Treatments in Cynomolgus Macaques ().

Here we present the results of experiments involving cynomolgus macaques, in which a model of traumatic spinal cord injury (TSCI) was created by using a balloon catheter inserted into the epidural space. Prior to the creation of the lesion, we inserted an EMG recording device to facilitate measurement of tail movement and muscle activity before and after TSCI. This model is unique in that the impairment is limited to the tail: the subjects do not experience limb weakness, bladder impairment, or bowel dysfunction.

Reduced variability of acetabular cup positioning with use of an imageless navigation system.

Positioning the acetabular component is one of the most important steps in total hip arthroplasty; malpositioned components can result in dislocations, impingement, limited range of motion, and increased polyethylene wear. Conventional surgery makes use of specialized alignment guides provided by the manufacturers of the implants. The use of mechanical guides has been shown to result in large variations of cup inclination and version.

Similarities and differences in the treatment of spine trauma between surgical specialties and location of practice.

Study Design: Questionnaires administered to practicing orthopedic and neurosurgical spine surgeons from various regions of the United States and abroad.

Objectives: To determine similarities and differences in the treatment of spinal trauma.

Summary Of Background Data: Spinal trauma is generally referred to subspecialists of orthopedic or neurosurgical training.

Traumatic labral avulsion from the stable rim: a constant pathology in displaced transverse acetabular fractures.

Introduction: During the treatment of a malunited transverse acetabular fracture, a hitherto undescribed extended avulsion of the labrum from the stable acetabular fragment was found. Based on the labral pathomorphology present in this case, the hypothesis was put forward that traumatic acetabular labral avulsions are a constant phenomenon in transverse acetabular fractures.

Patients And Methods: Fourteen patients underwent capsulotomy and/or surgical dislocation of the involved hip to facilitate open reduction and internal fixation of transverse acetabular fractures.

An algorithm for the treatment of Vancouver type B2 periprosthetic proximal femoral fractures.

The number of individuals with periprosthetic fractures of the proximal part of the femur is increasing. Multiple treatment methods have been described but none that correlate to fracture type and few with mostly good-to-excellent results. This article describes an algorithmic reconstruction tactic for treating patients with periprosthetic fractures associated with a loose femoral component.
