Thumb - Proximal phalanx: Articular (head) - Oblique

General considerations

Unicondylar fractures of the proximal phalanx can be short or long oblique, or comminuted. Typically they are the results of sports injuries, caused by axial load combined with lateral angulation of the finger.
Condylar fractures tend to be very unstable and should usually be treated operatively. If conservative treatment is attempted, secondary displacement, leading to angulation of the finger, often occurs.
