Painful radioulnar convergence following resection of the distal ulna can produce substantial disability and prove a challenging surgical problem, particularly in the revision setting. The purpose of this study was to evaluate the outcome of a series of patients with chronic distal radioulnar joint instability or multiple prior procedures treated with linked distal radioulnar joint arthroplasty with the APTIS prosthesis. A series of ten patients were identified with a mean follow up of 4.0 years. At final follow-up nine of ten implants survived free from revision or removal, with patients experiencing good pain relief and functional outcomes, with reasonable overall satisfaction in all seven patients who returned the questionnaires. Despite the medium-term follow-up and small number of patients, our results suggest the linked distal radioulnar joint arthroplasty may be a viable option for treating painful radioulnar convergence following multiple failed procedures at the distal radioulnar joint.
