Abstract:

Objective To investigate fracture type and surgical treatment of ulnar styloid process according to its anatomic features. Methods Based on different attachment points of ulnar collateral ligament(UCL) and triangular cartilage plate on ulnar styloid process, the fracture of ulnar styloid process were divided into tip fracture (typeⅠ) and base fracture (typeⅡ) . based on fracture type, special surgical methods were performed: Kirschner wire combined with steel wire, mini-screw, fine steel wire or absorptive thread, Kirschner and other surgical methods. Results 106 patients were followed up about 8-42 months, averagely 15 months. All patients healed well. According to the Garland and Werley score, 76 cases were excellent, 22 good, 6 fair and 2 poor, with the excellent and good rates of 92.4%. 2 cases suffered from ulnar styloid fracture combined with distal radial fractures, received rigid internal fixation. However, fracture position lost and resulted little deformity and the pain of ulnar wrist. Wire breakage appeared in 3 cases. Conclusions detailed understanding of anatomical features, accurate judging of fracture type,  suitable surgical fixation, and early functional exercises, are favorable for functional recovery of wrist fractures.
