Innovative Approach to Unicondylar Proximal Phalangeal Fracture Fixation: Combining Antegrade Intramedullary Pinning With Flexion Proximal Interphalangeal Joint Transfixation.

Abstract

Various surgical techniques have been described for the fixation of displaced unicondylar fractures of the proximal phalanx, with K-wire and interfragmentary screws being the most commonly used. Although open reduction with joint exposure can provide direct visualization and allow for anatomic reduction, its potential drawbacks, such as joint stiffness and loss of range of motion, are of significant concern. We introduced a novel fixation technique for displaced unicondylar fractures of the proximal phalanx using antegrade intramedullary pinning and transfixation of the proximal interphalangeal joint, which is simple, effective, and does not require open reduction.
