Advances in neurosurgical education: literature review of mixed-reality simulation models and novel mixed-reality spine prototype.

Objective: Mixed-reality (MR) applications provide opportunities for technical rehearsal, education, and estimation of surgical performance without the risk of patient harm. In this study, the authors provide a structured literature review on the current state of MR applications and their effects on neurosurgery training. They also introduce an MR prototype for neurosurgical spine training.

Optimization of 3D-titanium interbody cage design. Part 1: in vitro biomechanical study of subsidence.

Background Context: Cage subsidence is a complication of interbody fusion associated with poor clinical outcomes. 3D-printed titanium interbody cages allow for the alteration of features such as stiffness and porosity. However, the influence of these features on subsidence and their biological effects on fusion have not been rigorously evaluated.

Optimization of 3D-titanium interbody cage design. Part 1: in vitro biomechanical study of subsidence: Optimizing 3D-titanium interbody cage design.

Background Context: 3D-printed titanium cage designs can incorporate complex, porous features for bone ingrowth and a greater surface area for minimizing subsidence. In a companion study (Part 1), we determined that increased surface area leads to decreased subsidence; however, it remains unclear how increasing the cage surface area, resulting in a smaller graft aperture, influences fusion.

Purpose: We evaluated the effects of surface area of 3D-printed titanium cages and the use of autologous bone grafts on spinal fusion in sheep.

Management of cerebrospinal fluid leak after a minimally invasive lumbar decompression procedure: illustrative case.

Background: Neurogenic claudication caused by lumbar stenosis is a prevalent disorder of the spinal canal for which many treatment options exist. The mild (minimally invasive lumbar decompression) procedure has recently been introduced as a safe and effective alternative to medical management in the treatment of lumbar stenosis. However, data on complications are rarely reported, and the incidence of complications, when reported, is frequently assessed at 0% in the literature.

Is There an Association Between Spine Surgeon Academic Productivity and Patient Satisfaction Ratings?

Background And Objectives: Physician rating websites (PRWs) are increasingly used by patients to find health care providers. This study explores spine neurosurgeon PRW ratings and their relationship with academic productivity.

Methods: A retrospective study was conducted from November 2022 to May 2023 that included 1990 neurological surgeons listed in the American Association of Neurological Surgeons database with a subspecialty in spine.
