There are some implants for distal end fracture of the clavicle. The purpose of this study was to compare the clinical outcome between Scorpion Plate which doesn't cross AC joint and Wolter Plate which does cross AC joint. We evaluated 7 patients who were treated by Scorpion Plate(group S)and 9 patients who were treated by Wolter plate(group W)at Japanese Red Cross Society Wakayama Medical Center from 2003 to 2007. The mean duration of abduction limit was 6 weeks in group S, 20 weeks in group W. The mean duration patients were able to achieve abduction at 90° was 2.1 weeks in group S, 4.8 weeks in group W, at 180° was 6.3 weeks in group S, 27.3 weeks in group W. The mean ROM at 1, 3, 6 months was 116° 155° 165° in group S, 76° 88° 164° in group W respectively. The mean duration until removal of the implant was 30 weeks in group S, 20 weeks in group W. ROM improved earlier in group S than in group W because Scorpion plate doesn't cross AC joint and releases the abduction limit early. In group S surgeons could wait to remove the implant until complete bone union. However ROM at 6 months was the same in both groups.
