Radial head fractures constitute 33% of all elbow fractures. In cases of unreconstructible fractures, the resection of the head was advocated. Radial head arthroplasty is an alternative way of the treatment. As the implantation could end up with complications, thus new and better designs are constantly looked for. One of such designs is modal/bipolar radial head endoprosthesis. The aim of this paper is to assess the functional outcome following the implantation of this endoprosthesis using movement analysis system. Seven patients participated in the study: 5 after implantation of endoprosthesis and 2 after surgical reconstruction of the radial head. The upper extremity movements with EMG were assessed during gait and pronation/supination movements with and without the external load. The functional abilities of patients with radial head endoprosthesis do not differ from those of the patients after the elbow reconstruction. This allows the patients normal, daily activity, with no restrictions and pain.
