Demographic data, range of motion, grip strength, and patient-reported outcome measures (PROMs: Quick Disability of the Arm, Shoulder, and Hand; Patient-Rated Wrist Evaluation; modified Mayo Wrist Score [mMWS]; and visual analog scale [VAS] for pain) were collected. Complications were classified as major (requiring surgery) or minor (treated conservatively).<\/jats:p>\n                  <jats:p>The average follow-up was 3.37 years (standard deviation, 3.51; range, 0.04\u201315.62 years). A total of 30% of patients (n\u2009=\u200914) were followed for more than 5 years. Postoperatively, supination significantly increased and VAS pain scores improved significantly. Patients also experienced improved function in the operative wrist as assessed by the mMWS. Patients with prior DRUJ and\/or triangular fibrocartilage complex surgery were more likely to have additional diagnoses at the time of definitive surgery and our postoperative outcomes varied based on prior surgery and additional diagnoses, with a trend toward higher pain levels and worse PROMs. The overall complication rate was 17%, with one major complication consisting of a posttraumatic periprosthetic ulna fracture. All other complications were minor. Implant survival was 100%.<\/jats:p>\n                  <jats:p>Semiconstrained DRUJ arthroplasty significantly improves pain levels and functional outcomes at short- to midterm follow-up. Patients who had undergone previous related surgeries were showed a trend toward higher postoperative pain levels and worse PROMs. Although complications were common, overall patient satisfaction and implant survivorship were high.<\/jats:p>\n                  <jats:p>Level IV<\/jats:p>","DOI":"10.1055\/s-0044-1791498","type":"journal-article","created":{"date-parts":[[2024,10,16]],"date-time":"2024-10-16T19:12:57Z","timestamp":1729105977000},"page":"064-071","source":"Crossref","is-referenced-by-count":2,"title":["Semiconstrained Distal Radioulnar Joint Arthroplasty: Functional Outcomes and Complications"],"prefix":"10.1055","volume":"15","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-1004-4205","authenticated-orcid":false,"given":"Matthew J.","family":"Pina","sequence":"additional","affiliation":[{"name":"Christine M.
