Intra-Articular Fracture of Proximal Phalanx of Thumb

Image

Proximal phalanx fractures can be epiphyseal or shaft fractures and can be intra-articular or extra-articular. They are most often the result of forced rotation, hyperextension or direct trauma. The fracture is generally well seen on plain radiographs, angulation of these fractures is best seen on the lateral projection. The clinical consolidation is in 4 or 6 weeks; radiological consolidation takes longer. However, it should be noted that the fingers don't tolerate immobilization very well so it shouldn't exceed 3 weeks.
