Malunion of the distal radius and forearm in posttraumatic or congenital disorders are rare diagnosis but can lead to considerable complaints and problems. In the event of a symptomatic malunion, especially in young patients, correction must always be considered to achieve the most anatomical result.

3D-virtual planning and mirroring of the opposite side is a well know procedures established in the last decade. To give justice to the individual anatomy also printed individual titanium-implants, first introduced in maxilla-fascial surgery, are now available for radius and forearm reconstruction. We present the technical planning and implementation of this new procedure as well as the experience with such patient specific guides and 3D printed plates will be discussed and illustrated by specific cases.

During the session two demo surgeries of an intra-articular radius malunion and of a forearm malunion will be performed. After going through the case planning and the virtual 3D reconstruction, the cases will be treated with 3D printed guides and 3D printed patient specific plates.
