The purpose of this study was to introduce a novel method of percutaneous achievement and maintenance of reduction for acute displaced scaphoid fractures and evaluate the feasibility of this method in treating acute displaced scaphoid fractures as well as explore its indications.
From February 2012 to March 2014, 15 patients with acute displaced scaphoid fractures were treated with our technique. Two Kirschner wires were used to achieve and maintain the reduction of the scaphoid fractures throughout the entire process of the traditional percutaneous screw fixation process. The following parameters including function scores according to modified Mayo wrist scoring system, range of motion (ROM) of the wrist, grip strength, pinch strength, healing time, time to return to work, and final outcomes were recorded.
All patients were followed up with a mean period of 2.5 years (range, 2–3.5 years). All fractures healed with a mean of 9.3 weeks (range, 7–11.5 weeks). All patients returned to pre-injury level of activity within six weeks. The functional scores averaged 90.3 (range, 80–100). ROM of the wrist was equal to that of the contralateral side at three months postoperatively. Grip strength and pinch strength compared with contralateral were 98% and 92%, respectively. All were satisfied with the final outcomes.
Our technique is successfully performed in acute displaced scaphoid fractures resulting in shortened immobilization and prompt functional recovery. It broadens the indications of the percutaneous method, which means the advantages of the percutaneous method are maximally reserved whilst the drawbacks of open reduction were avoided.
