title: Precise ulna-shortening osteotomy with a new device.
abstract: Ulna-shortening osteotomy has become a standard procedure for various ulnar-sided wrist disorders. A precise osteotomy, good coaptation of the osteotomy surfaces, and rigid internal fixation are mandatory to achieve good results from ulna-shortening osteotomy. Various techniques and devices have been introduced to assist in this difficult procedure. We developed a device that enables a precise ulna-shortening osteotomy and fixation with a 3.5-mm AO dynamic compression plate. Twenty-four ulnas were shortened with the aid of this device. The average follow-up period was 36 months. Radiologic union occurred at an average of 8.1 weeks after surgery. There were no nonunions or delayed unions. This study shows that an ulna-shortening procedure with this device enables precise shortening and predictable union of the ulna.
