Universal 2 total wrist arthroplasty: high satisfaction but high complication rates:

The Universal 2 total wrist arthroplastyis intended to alleviate wrist painand restore function. There is limited evidence regarding its success and safety. We report outcomes in 48 wristsof 46 patients with Universal 2 arthroplastybetween 2006 and 2014. We recorded range of motion of the operated wrist, patient satisfaction, complication and revision rates, and radiological appearances of the wristswith mean follow-up of 7 years (3.5 to 11 years). We found a significant improvement in DASHscores after surgery, with active range of wristmotion being 33° flexion and 24° extension. Thirty-nine patients would undergo the procedure again if he had similar wristproblems. Twenty-three patients had loosening of at least one component of the implant. Complications were found in 13 wrists; seven underwent revision. We conclude that the Universal 2 arthroplastyproduces significant improvements in DASHscores and high levels of satisfaction of the patients. However, the surgery has a high complication rate....
