Abstract |
Purpose To determine the value of the treatment of ulnar styloid fractures using miniscrew and tension-band suture augmentation. Materials and Methods: Fourteen displaced type 2 ulnar styloid fractures accompanied by unstable distal radius fractures were managed with open reduction and internal fixation using a miniscrew. The fixation was augmented with a figure of 8 tension-band suture. Two threads of 1-0 absorbable Vicryl suture were passed around the ulnocarpal ligament and crossed over ulnar surface of styloid process obliquely. After passage through a bony tunnel at ulnar neck, two thread ends were tied tightly together. Short arm splint immobilization was maintained for 3 to 4 weeks and then the range of motion exercise was started. The radiologic bony union, ulnar sided wrist pain and range of pronationsupination motion were evaluated. Final results were assessed according to the modified Green and O’Brien’s criteria. The mean follow up period was 13.7 months (8~18 months). Results: Ten of 14 patients showed radiologic bony union within 11 weeks. Four patients showed delayed union, in which the union time ranged from 5 months to 11 months postoperatively. The final functional results according to the modified Green and O’Brien’s criteria were ‘excellent’ in 8 ‘good’ in 4 and ‘fair’ in 2. Conclusion: Open reduction and internal fixation of ulnar styloid base fractures using miniscrew and tensionband suture augmentation resulted in high rate of bony union and good fuctional outcome. |
