This project is set to describe by objective measures as the range of motion and weight-bearing ability of the distal radioulnar joint one to five years after primary implantation of a Scheker total distal radioulnar joint prosthesis.The range of motion and stability of the distal radioulnar joint (DRUJ) are important outcomes to preserve function, especially the pronation and supination. Unlike other ulnar endoprostheses that replace only the ulnar head, the Scheker prosthesis replaces the ulnar head, resurfaces the lesser sigmoid notch, and is semi-constrained in design.

Primary outcomes of this study are active DRUJ range of motion (pronation and supination) and weight-bearing ability in neutral and pronated position.
Time frame: Follow-up time between 12-60 months after primary implantation of the Scheker prothesis
Secondary outcomes of this study are radiological parameters, pain level by Visual Analog Scale, objective functional parameters (passive stability, grip strength), subjective functional parameters, and complications affecting the examined wrist.
Time frame: Follow- up time between 12-60 months after primary implantation of the Scheker prothesis
