Carbon Fiber Reinforced Hybrid Polyaryl-Ether-Ether-Ketone (PEEK) Spinal Fixation System: Technical Features and Preliminary Clinical Trial.
Indian J Orthop
January 2025
Department of Orthopaedic Surgery, Hillel Yaffe M.C., 3100 Hadera, Israel.
Objective: To present the clinical result of spinal fixation system made entirely of Carbon-Fiber-Reinforced (CFR)-Hybrid Polyaryl-Ether-Ether-Ketone (PEEK).
Summary Of Background Data: Fusion surgery has been used to treat chronic low back pain caused by degenerative disk disease (DDD). The traditional pedicle screw system made of titanium, though biocompatible, can lead to complications, such as stress shielding and implant failure.
Prediction of postoperative stroke in patients experienced coronary artery bypass grafting surgery: a machine learning approach.
Front Cardiovasc Med

Department of Cardiovascular Surgery, Union Hospital, Tongji Medical College, Huazhong University of Science and Technology, Wuhan, Hubei, China.
Background: Coronary artery bypass grafting (CABG) surgery has been a widely accepted method for treating coronary artery disease. However, its postoperative complications can have a significant effect on long-term patient outcomes. A retrospective study was conducted to identify before and after surgery that contribute to postoperative stroke in patients undergoing CABG, and to develop predictive models and recommendations for single-factor thresholds.

December 2024
Department of Plastic Surgery, Union Hospital, Tongji Medical College, Huazhong University of Science and Technology, Wuhan, 430022, People's Republic of China.
Purpose: Successful regeneration of cranial defects necessitates the use of porous bone fillers to facilitate cell proliferation and nutrient diffusion. Open porous microspheres, characterized by their high specific surface area and osteo-inductive properties, offer an optimal microenvironment for cell ingrowth and efficient ossification, potentially accelerating bone regeneration.
Materials And Methods: An in vitro investigation was conducted to assess the physicochemical properties, porosity, and biocompatibility of PHA-nano-clay open porous microspheres.

Institute of Materials Science and Engineering, Faculty of Mechanical Engineering, Lodz University of Technology, Łódź, Poland.
Fused Filament Fabrication (FFF) printing is one of the most all-purpose manufacturing techniques, allowing many complicated parts to be obtained at lower cost. This is especially important in prosthetics, where more complex prostheses, especially of a hand, can cause enormous expense. However, providing the full functionality of a prosthesis often requires combining materials with different properties, such as rigidity and flexibility.
