Thermally reconfigurable vitrimer-based orthopedic cast for distal radius fracture immobilization

Abstract

An orthopedic cast made of a vitrimer polymer lattice shell additively manufactured from anatomical scan data. The cast provides ventilation, structural immobilization, and thermal reshaping capability while maintaining mechanical integrity. A cast system for adult distal radius fractures is disclosed, a vitrimer-based polymer lattice shell custom-generated through anatomical modeling and additive manufacturing. A patient-specific immobilization device with modular segments and structural zones tailored for the distal forearm and wrist region. Using 3D anatomical input and a proprietary digital workflow, the system calculates fracture-appropriate cast geometry, including variable wall thickness and ventilation cell size. The cast design accommodates fracture type, swelling potential, and ergonomic function while permitting surgical site access.
