GmbH, Graz, Austria) could become a useful treatment option. This study aimed to evaluate the results of this anatomically pre-contoured plate regarding patients with unstable or displaced distal ulnar fractures.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Methods<\/jats:title>\n                <jats:p>In a prospective clinical trial, 20 patients (18 female, two male; mean age 70\u00a0years (24\u201391\u00a0years)) with unstable or displaced distal ulna fractures between December 2010 and August 2015 were analyzed. All patients were treated with open reduction and internal fixation using the DUL. They were evaluated at three follow-up appointments at 3, 6 and 12\u00a0months postoperatively regarding their bone healing, ulnar variance (UV), range of motion (ROM) and grip strength. Patient related outcomes were measured using the Disability of the Arm, Shoulder and Hand (DASH), the Patient Rated Wrist Evaluation (PRWE) questionnaires, and the Visual Analogue Scale (VAS). The results after one year were compared to the outcome of the healthy contralateral side.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Results<\/jats:title>\n                <jats:p>All fractures treated with open reduction and internal fixation using the Distal Ulna Locking Plate healed within 6\u00a0months and showed stable ulnar variances after surgery. ROM (rotational plane 81.1\u2009\u00b1\u20099.0\u00b0, sagittal plane 55.1\u2009\u00b1\u200914.6\u00b0, frontal plane 33.0\u2009\u00b1\u20099.4\u00b0) and grip strength (18.7\u2009\u00b1\u20097.1\u00a0N) at the follow-up after 12\u00a0month had similar values compared with the uninjured side. The mean DASH score (36.4\u2009\u00b1\u200929.0), the PRWE-score (14.5\u2009\u00b1\u200927.0), and the VAS (at rest 0.5\u2009\u00b1\u20091.1, during activity 1.2\u2009\u00b1\u20092.4) after one year had no significant difference to the uninjured side.
