Fracture of the base of first metacarpal (Bennett fractures) treated with close reduction and Kirschner wire fixation: 16-25 years outcomes

Abstract

Bennett's injury is a fracture dislocation of the first carpo-metacarpal joint. The causative mechanism is axial overloading along the first metacarpal with simultaneous flexion. The palmar oblique ligament holds the palmar marginal fragment in its anatomical position. The different treatment options are the following: a) using local anesthetics in Emergency Room (ER) or typical surgical treatment in operative room with close reduction followed by percutaneous Kirschner wire, b) open reduction and internal fixation with screws or tension band wiring, c) external fixation. The aim of this study is to report a series of patients with Bennett's fractures who were treated under local anesthesia with closed reduction and percutaneous K-wire fixation, and the presentation of the long term, (16-25 years), follow-up outcomes, which were very good in all the reported patients without development of posttraumatic arthritis.
