These are partial articular fractures of the distal radius involving the dorsal rim (Rea-Barton fracture), with a lateral fracture line in the sagittal plane. Ref. D. L. Fernández, J. B. Jupiter. Fractures of the distal radius.

The detachment of the dorsal fragment causes the subluxation of the carpus or its complete dislocation (B2.3). Anatomic reduction is mandatory not only because of its articular condition but also because it is essential to reconstruct the dorsal brim of the radius in

order to prevent the displacement of the carpus. The internal fixation must be stable, preferably performed with lag screws. Placement of plates in the dorsal aspect of the radial epiphysis should be avoided whenever possible because they interfere with the pathways of the tendons.

These are partial articular fractures of the distal radius, that involve the dorsal rim and are associated to a dislocation of the carpus.. Ref. D. L. Fernández, J. B. Jupiter. Fractures of the distal radius.

Surgeon. DF.

These fractures share the characteristics of the previous subgroup (B2.2) but with a greater displacement, therefore with greater damage of the soft tissues such as the rupture of the ulnar-carpal ligaments or the pull-off fracture of the ulnar styloid.

The reduction must be performed as an emergency in order to prevent neurovascular compromise at the volar tunnels. The internal fixation is performed according to the “state of the art”, protected or not with an external fixator. Reconstruction of the ulnar styloid is essential.
