Summary: Anatomical models have served as essential tools in medical instruction for thousands of years, countering the challenges of relying on human cadavers for anatomical knowledge. The collaboration between artists, physicians, and anatomists in creating these models has advanced anatomical instruction at a tremendous rate. From traditional materials like metal and wax to modern computerized representations, anatomical models have evolved to provide accurate and detailed anatomical information.

Summary: A study on the mechanical properties and fracture propagation mechanism of three-dimensional printed samples reveals that the strength of these samples is weaker compared to natural rock, and the fracture patterns are characterized by regional fracture bands. It is also found that the heterogeneous cementing conditions cause heterogeneity in the mechanical properties of the printed samples.

Summary: This study investigates the effect of temperature on the interfacial properties of continuous fiber-reinforced thermoplastic composites through molecular dynamics simulations. It reveals a positive correlation between the interfacial strength and forming temperature, as well as an impact of loading temperature on the failure mode of the composites. The mechanical properties of the thermoplastic matrix also deteriorated with increasing loading temperature, resulting in a shift from adhesive failure to cohesive failure.

Summary: The purpose of this study was to demonstrate the potential effects of using personalized silicone models for mitral valve repair (MVR) simulation one day prior to the actual surgical procedure. Based on preoperative 3D echocardiography recordings, flexible replicas of the pathological mitral valves were produced and used to simulate the upcoming MVR. The integration of personalized surgical planning into the clinical routine of 6 MVR cases with 3 different surgeons showed positive responses and benefits such as reduced inspection time and fewer sizing attempts.

Summary: This study retrospectively analyzed the diagnosis, treatment, outcomes, and current patient management algorithm for neonatal myocardial infarction in 21 patients. The results showed that regional wall motion abnormalities were important criteria for diagnosis. Most patients recovered after treatment, with a low mortality rate and good restoration of left ventricular function. The proposed algorithm can improve patient outcomes.

Summary: Corticocortical evoked potentials (CCEPs) have emerged as a valuable intraoperative monitoring technique in eloquent brain tumor surgery, aiding in preserving critical functional areas. Current research shows the potential of CCEPs in guiding surgical decision making, reducing the risk of postoperative neurological deficits, and mapping functional connectivity, but further research and standardization are needed.

Summary: This study aimed to compare the effect of different Modic changes (MC) grades on the cage subsidence rate after spinal interbody fusion surgery. A meta-analysis was conducted on relevant randomized controlled trials and cohort studies. The results showed that MC may be associated with a higher cage subsidence rate. With the increase in MC grades, the incidence of subsidence decreased gradually, but it was always higher than that in the non-Modic changes (NMC). Oblique lumbar interbody fusion may be a better treatment choice for lumbar degenerative disease with MC.

Summary: Early exposure to neurosurgery during medical school is critical for improving recruitment into the specialty. However, about 30% of medical schools in the U.S. lack a neurosurgery program, limiting students' exposure to the field. Virtual education, facilitated by webinars during the pandemic, has advantages such as global outreach and accessibility for international medical students. This review identifies and describes 16 educational resources, serving as a guide for medical students interested in neurosurgery.
