his instruction refers to a set of 4.0ChLP locking plates intended for the treatment of fractures of distal radius. The plates discussed are a part of the ChLP locking plates system developed by ChM sp. z o.o. The implants presented herein are made of titanium, titanium alloys and cobalt alloy with ISO 5832. These are Quality Manage-ment Systems, ISO 9001, ISO 13485 and Directive 93/42/EEC that guarantee high quality of implants.The system for distal radial fractures treatment consists of:• Implants (locking plates, locking screws and standard cortical screws),• Instrument set,• Surgical technique.I.1. INDICATIONSThe main purpose of surgical treatment of radial bone fractures with 4.0ChLP locking plates is its anatomical reconstruction, and faster recovery to public and profes-sional life. The stabilization with this method provides the possibility of: precise fracture reduction, stable angular immobilization of bone fragments while preserving the blood supply.Plates are intended for treatment of:• fractures in distal part of radial bone and fractures extending to radial bone shaft,• compound exta-articular and intra-articular fractures,• osteotomies,• possibility of using them in treatment of other small bones fractures.I.2. CONTRAINDICATIONS• infections,• physical maturation.
