Introduction: Reconstructing large bone defects for lower limb salvage in the pediatric population remains challenging due to complex oncological or septic issues, limited surgical options, and lengthy procedures prone to complications. The vascularized double-barreled fibula free flap is pivotal for reconstructing large bones. In this article, we report our experience with this technique in the surgical management of pediatric tibial bone defects.

Background: Distal biceps tendon rupture is an injury that causes a significant reduction in strength and endurance. Combined cortical button and interference screw fixation has been utilized via single-incision technique. There are limited data describing this technique utilizing a double-incision approach.

In this work, the fracture mechanism of winding carbon-fiber-reinforced plastics (CFRPs) based on epoxy matrices reinforced by polysulfone film was investigated. Two types of polymer matrices were used: epoxy oligomer (EO) cured by iso-methyltetrahydrophthalic anhydride (iso-MTHPA), and EO-modified polysulfone (PSU) with active diluent furfuryl glycidyl ether (FGE) cured by iso-MTHPA. At the winding stage, the reinforcing film was placed in the middle layer of the CFRP.

The key structural components of a wind turbine blade, such as the skin, spar cap, and shear web, are fabricated from fiber-reinforced composite materials. The spar, predominantly manufactured via resin infusion-a process of resin injection and curing in carbon fibers-is prone to initial defects, such as pores, wrinkles, and delamination. This study suggests employing the pultrusion technique for spar production to consistently obtain a uniform cross-section and augment the reliability of both the manufacturing process and the design.
