Nonoperative Treatment of Dorsally Dislocated Distal Radius Fractures in Adults With an Individualized 3D Printed Brace.

The distal radius fracture brace is constructed from biocompatible materials (like polylactic acid; PLA) and the skin is protected by commercially available and approved waterproof padding (like Aquacast®). The major brace components are connected and reinforced with carbon rods and plastic bolt-nut connections. PLA is extensively used, for example in surgical implants, but also as biological alternative for plastics. Aquacast® is approved and used as waterproof padding in swim plaster. The biomechanical function of the distal radius brace has been tested successfully in an ex vivo setting (results to be published). The DRFB includes the distal forearm, wrist an base of the hand. The thumb and fingers are free and the DRFB provides more movement than classical casting.
