These fractures are very similar to the previous subgroups but involve a greater degree of subluxation of the carpus, such that it is often completely dislocated dorsally.
In this case, these are classified by AO/OTA as 2R3B2.3.
There is usually a significant degree of soft-tissue damage in these injuries. The neurovascular structures are particularly at risk, especially the median nerve, because of the instability and wide displacement.
There may be an associated ulnar injury. This is usually a fracture of the ulnar styloid process, but other ulnar fractures are possible.
