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

The Universal 2 total wrist arthroplasty is intended to alleviate wrist pain and restore function. There is limited evidence regarding its success and safety. We report outcomes in 48 wrists of 46 patients with Universal 2 arthroplasty between 2006 and 2014. We recorded range of motion of the operated wrist, patient satisfaction, complication and revision rates, and radiological appearances of the wrists with mean follow-up of 7 years (3.5 to 11 years). We found a significant improvement in DASH scores after surgery, with active range of wrist motion being 33 degrees flexion and 24 degrees extension. Thirty-nine patients would undergo the procedure again if he had similar wrist problems. 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 arthroplasty produces significant improvements in DASH scores and high levels of satisfaction of the patients. However, the surgery has a high complication rate. Level of evidence: IV
