Assessment of a Perfusion and Ventilation Method for Detecting Lung and Liver Injury in a Cadaveric Model.

Surgical simulation models have been developed using post-mortem human subjects (PMHS). These models involve the pressurization and ventilation of the PMHS to create a more realistic environment for training and the practice of surgical procedures. The overall objective of this study was to determine the feasibility of a previously developed surgical simulation model to detect soft tissue injuries during a ballistic impact to the torso.

Evaluation of Spinous Process Tethering at the Proximal End of Rigid Constructs: In Vitro Range of Motion and Intradiscal Pressure at Instrumented and Adjacent Levels.

Background: Adult spinal deformity surgery requires use of long thoracolumbar instrumentation, which is associated with risk of postoperative proximal junctional kyphosis (PJK). Tethering has been used in spinal surgery but not around the spinous process (SP) in the context of preventing PJK.

Methods: Researchers applied a nondestructive hybrid loading protocol to 7 T8-L2 cadaveric specimens in flexion-extension, lateral bending, and axial rotation (AR).

Outbreak of Electronic-Cigarette-Associated Acute Lipoid Pneumonia - North Carolina, July-August 2019.

Is lateral stabilization enough in thoracolumbar burst fracture reconstruction? A biomechanical investigation.

Background Context: Traditional reconstruction for burst fractures involves columnar support with posterior fixation at one or two levels cephalad/caudad; however, some surgeons choose to only stabilize the vertebral column.

Purpose: The aim was to distinguish biomechanical differences in stability between a burst fracture stabilized through a lateral approach using corpectomy spacers of different end plate sizes with and without integrated screws and with and without posterior fixation.

Study Design/setting: This was an in vitro biomechanical study assessing thoracolumbar burst fracture stabilization.

Undertapping of Lumbar Pedicle Screws Can Result in Tapping With a Pitch That Differs From That of the Screw, Which Decreases Screw Pullout Force.

Study Design: Survey of spine surgeons and biomechanical comparison of screw pullout forces.

Objective: To investigate what may be a suboptimal practice regularly occurring in spine surgery.

Summary Of Background Data: In order for a tap to function in its intended manner, the pitch of the tap should be the same as the pitch of the screw.
