Dorsal Cortical Alignment Predicts Functional Outcomes in Proximal Phalangeal Fractures Treated with Intramedullary Headless Compression Screws but Not in Metacarpal Fractures.

: Intramedullary headless compression screw (IMHCS) fixation has emerged as a minimally invasive and biomechanically robust method for treating metacarpal and proximal phalangeal fractures. While the clinical outcomes are generally favorable, the impact of anatomical fracture reduction on postoperative function has not been systematically examined. : We retrospectively analyzed 69 patients (41 metacarpal, 28 proximal phalanx) treated with IMHCSs between June 2020 and March 2025.

Sedentary behaviour and cardiometabolic health: Integrating the potential underlying molecular health aspects.

During the last decades, sedentary behaviour has been recognised as an interdependent risk factor for cardiometabolic health and premature mortality. Prolonged sedentary behaviour is associated with increased risks for chronic non-communicable diseases (NCDs) such as obesity, chronic respiratory diseases, type 2 diabetes mellitus, cardiovascular diseases and cancer due to disturbances in cardiometabolic health. However, despite the increased evidence supporting these associations, the underlying molecular mechanisms to the development of these NCDs remain largely unknown.

Fully Threaded Versus Partially Threaded Intramedullary Headless Compression Screw Fixation for Proximal Third Fractures of the Proximal Phalanx: A Biomechanical Study.

Purpose: The purpose of this study was to compare the maximal elastic force and deformation resistance of two commonly used headless compression screw systems, a fully threaded 2.5 mm screw and a partially threaded screw of the same dimensions, in a cadaveric model of a human transverse proximal third fracture of the proximal phalanx.

Methods: Six fresh frozen cadavers were used, and the proximal phalanges of the index, long, and ring fingers of both hands were dissected.
