Surgical treatment of tibial nonunion after wounding by high velocity missile and external fixators: A case report [PDF]

Srpski Arhiv za Celokupno Lekarstvo, 2012
Introduction. The missiles of modern firearms can cause severe fractures of the extremity. High velocity missile fractures of the tibia are characterized by massive tissue destruction and primary contamination with polymorphic bacteria.

Deep Learning Network‐Tailored Microenvironment Matching of 4D Bioprinting Bioactive Scaffolds for Bone Regeneration

Advanced Science, EarlyView.
A DLN dataset was built to analyze MABS composition versus in vitro/in vivo osteogenesis and angiogenesis. An MLP neural network, taking BG morphological parameters as input, extracts bioactive features from these datasets. A rabbit tibial defect model then validates 4D‐printed MABS for adaptability and bone regeneration in critical defects.

Bioadhesive‐Integrated 3D‐Printed Multilayer Scaffolds Secure a Mechanically‐Stable Osteoimmune Niche for Enhanced Bone Augmentation

Advanced Science, EarlyView.
A 3D‑printed multilayer adhesive scaffold, firmly anchored to bone defects by simple finger pressing, suppresses micromotion and secures mechanical stability of the osteogenic niche. This stabilization likely contributes to the enhanced bone augmentation by fostering a pro‑regenerative mechano‐immune profile—characterized by M2‑like macrophage ...

Associations Between Area Deprivation Index and the Time to Presentation of Scaphoid Fractures

Journal of Hand Surgery Global Online
Purpose: Scaphoid fractures are the most common carpal fractures and are prone to nonunion because of their retrograde blood supply. Delayed diagnosis or treatment increases the risk of nonunion and progression to scaphoid nonunion advanced collapse ...
