Endoprosthesis for radial head bone

Endoprosthesis for replacement of radial head, developed by ChM, Poland.


The indication for radial head replacement is a multifragmental, comminuted fracture of the radial head where stable
osteosynthesis is not possible.
System for radial head replacement consists of:
- implants,
- instrument set.

Indications for the radial head replacement in the case of comminuted fracture (Type III according to Mason Classification) are the following coexisting injuries:
- dislocation of the elbow joint together with radial head fracture;
- injury of the medial collateral ligament;
- injury of the lateral collateral ligament;
- Monteggia type injury with the olecranon fracture and the radial head fracture;
- fracture of the major part of the coronoid process (Types II and III);
- coexisting injury of the distal radioulnar joint (Essex-Lopresti type) or injury of the interosseus membrane;
- As a combination of the above - complex injury and instability.
The presented prostheses are made of cobalt alloy and UHMWPE polyethylene in accordance with ISO 5832 and ISO 5834 standards. High quality of the prostheses is confi rmed by Quality Management System ISO 9001, EN ISO 13485 and by meeting the requirements of 93/42/EEC Directive.
