Proximal phalanx fractures of the big toe involving angulation or dislocation of the articular surface require repositioning and fixation. We treated a patient with such a fracture using a novel wire-connected external fixator, the ICHI-FIXATOR® system. A 45-year-old male sustained an injury when slipping down the stairs and impacting his left big toe. Plain radiography and computed tomography revealed a proximal phalangeal fracture of the left big toe with dislocation of the articular surface and comminution. The surgical intervention was performed using 1.1-mm diameter C-wires and an external fixator. The patient regained ambulation and resumed work immediately after surgery. Four weeks postoperatively, all wires were removed on an outpatient basis. Eight months postoperatively, the patient experienced no pain during strenuous activities or exercises. This novel wire-connected external fixator provides reliable and secure fixation, facilitating a prompt return to normal daily activities. This technique may be an effective option for managing toe fractures. •Big toe fractures involving dislocation of the articular surface pose treatment challenges.•The ICHI-FIXATOR® system (IFS) is a novel wire-connected external fixator.•IFS may be an effective option for managing toe fractures.
