The XVS System During Open Spinal Fixation Procedures in Patients Requiring Pedicle Screw Placement in the Lumbosacral Spine.

Objective: This pilot study was undertaken to evaluate the safety, performance, and usability of the Xvision-Spine (XVS) System (Augmedics, Arlington Heights, IL) during open spinal fixation procedures in patients requiring pedicle screw placement in the lumbosacral spine.

Methods: The XVS System is an augmented reality head-mounted display (HMD) based on a computer navigation system designed to assist surgeons in accurately placing pedicle screws. It uses an HMD-mounted tracking camera to provide optical tracking technology, and provides the surgeon a translucent direct near-eye display of the navigated surgical instrument's location relative to the computed tomographic image.

Reliability of smartphone-based teleradiology for evaluating thoracolumbar spine fractures.

Background Context: Timely interpretation of computed tomography (CT) scans is of paramount importance in diagnosing and managing spinal column fractures, which can be devastating. Out-of-hospital, on-call spine surgeons are often asked to evaluate CT scans of patients who have sustained trauma to the thoracolumbar spine to make diagnosis and to determine the appropriate course of urgent treatment. Capturing radiographic scans and video clips from computer screens and sending them as instant messages have become common means of communication between physicians, aiding in triaging and transfer decision-making in orthopedic and neurosurgical emergencies.

[Posterior lumbar interbody fusion (PLIF stand-alone) for chronic low back pain].

Objective: To evaluate the fusion achieved by posterior lumbar interbody fusion--PLIF [B-TWIN, Disc-O-Tech) stand-alone in terms of intervertebral fusion on the basis of radiograph imaging.

Summary Of Background Data: Lumbar fusion is being used to reduce pain and decrease disability in patients with chronic low back pain. Different surgical techniques are available.

[Congenital cervical spondylolisthesis].

Cervical spondylolysis with spondylolisthesis is a complex abnormality involving the posterior elements of the cervical vertebra, and anterolisthesis of the same vertebra. Cervical spondylolysis is defined as a corticated cleft between the superior and inferior articular facets of the articular "pillar", the cervical equivalent of the pars intraarticularis in the lumbar spine. The typical radiological features of this condition are as follows: 1.
