Clinical application of Acutrak screws in the treatment of fresh scaphoid fractures

Objective To investigate the method and short-term effects of Acutrak screws in the treatment of fresh scaphoid fractures. Methods From January 2011 to January 2015, 11 cases of scaphoid fractures were treated by Acutrak headless compression screws. According to Herbert's classification, one case was type B1, 6 cases were type B2, 2 cases were type B3, and 2 cases were type B4. Volar approach was used in 7 cases, dorsal approach in 3 cases, and combined approach in 1 case. Two cases of type B4 had scapholunate dissociation and were treated by open reduction and fixation with simultaneous repair of scapholunate ligament. After the operation, short arm plaster fixation was used and exercises were gradually carried out after immobilization for 2 to 3 weeks. Results Postoperatively all the patients were follow-up for 12 to 24 months with an average of 16.5 months. The time of fracture healing was 7 to 15 weeks with an average of 11.4 weeks. According to the Mayo scoring system, wrist function at the final follow-up was rated as excellent in 6 cases, good in 3 cases and fair in 2 cases. Conclusion Acutrak headless compression screws can achieve reliable fixation and satisfactory treatment results. Key words: Scaphoid bone; Fractures,bone; Internal fixation; Screw
