Objectives/Interrogation: This study reports the results of 20 patients who have had a replacement of the distal radioulnar joint (DRUJ).
Methods: Between 2010 and 2018, 28 patients received an Aptis prosthesis. 20 out of these 28 patients were willing to undergo a final evaluation. We examened the functioal outcome and evaluated the DASH, PRWE and VAS score.
Results and Conclusions: The average results of these questionnaires were 33.5 for the DASH score, 38.7 for the PRWE and 4 for the VAS score. The mean flexion and extension were 68° and 57° respectively. The grip strenght recovered to 59% and pinch strenght even to 71% after surgery compaired to the non-operated side. One prosthesis was removed because of persistend pain and synovitis which brought our survival rate to 96.4%.
Since the introduction of this prosthesis good results. In our study we were able to find comparable results with high satisfaction rates.
