Phalangeal Neck Fractures
Phalangeal neck fractures are principally a pediatric problem and are often missed, which can lead to poor functional outcomes. Synonyms include subcapital, subcondylar, and supracondylar phalanx fractures. These fractures occur at the distal end of the proximal or middle phalanx, with the border digits most often affected. Radiographs must include at a minimum anteroposterior and lateral views, with the displacement more apparent on the lateral image. Phalangeal neck fractures most commonly displace with apex volar angulation and can often be malrotated as well. Very little remodeling potential exists and with the exception of the nondisplaced fractures (which themselves must be watched very closely), these injuries necessitate timely reduction and stabilization.
