Background: Total elbow arthroplasty (TEA) is increasingly used for expanding indications but complications like aseptic loosening and periprosthetic fractures persist. Our objective is to examine the biomechanical behavior of the total elbow implant in response to varying implant lengths by investigating the stresses and the stress shielding effect in the bone-implant assembly using finite element (FE) modelling.
Methods: A fourth-generation synthetic humerus sawbone and its corresponding digital model were used in this study.
Background and objective The epicondyles are commonly used surgical reference landmarks for elbow arthroplasty and external fixator application. This study aimed to investigate whether the epicondylar axis differed from the elbow's true flexion-extension (F-E) axis in terms of both rotational difference and translational offset. Methods Three-dimensional (3D) models of 15 cadaver elbows were created.

- The study compares the outcomes of using an operating microscope (OM) vs. standard loupe (SL) for reconstructing the hepatic artery in pediatric liver transplants, focusing on HA thrombosis rates.
- Analysis included data from 1,261 liver recipients, revealing that the OM group had significantly lower rates of HA thrombosis, better graft survival, and reduced overall mortality compared to the SL group.
- The findings suggest that incorporating microsurgical techniques, like OM, improves outcomes in pediatric liver transplantation, although some factors such as operation times and hospital stays showed no significant difference.
Introduction: Minimally invasive oncological resections have become increasingly widespread in the surgical management of cancers. However, the role of minimally invasive surgery (MIS) for gallbladder cancer (GBC) remains unclear. We aim to perform a systematic review and network meta-analysis of existing literature to evaluate the safety and feasibility of laparoscopic and robotic surgery in the management of GBC compared to open surgery (OS) by comparing outcomes.

Studies evaluating clinical outcomes of minimally invasive chevron and akin (MICA) procedure have shown shorter operation time, faster recovery, and smaller scars compared to the open approach. Previous biomechanical cadaveric studies have largely focused on the open approach with minimal on MICA.
