And each has the opposite dislocation > fracture of distal third of shaft of radius with disruption of the distal radaial ulnar joint (aka ulnar dislocation; [[Distal radial ulnar joint dislocation|DRUJ]]) usually from FOOSH in forced pronation or from a direct blow. ![[Pasted image 20230826004408.png]] ![[Pasted image 20230826004620.png]] ![[Pasted image 20241104183900.png]] ![[Pasted image 20241104184101.png]] transverse fracture through the mid shaft of left radius, which is a/w 100% dorsal displacement and shortening of 1.5 cm. distal radius is angulated 15 deg in palmar direction. distal ulnar-carpal joint is dislocated with dorsal displacement of the ulnar head. Galeazzi type fracture-dislocation **Complications** - [[Neurovascular assessment|ulnar nerve damage]] (rare) - [[Compartment syndrome]] - ulnar physeal injury → ulna shortening and issues with DRUJ - chronic disability -- non-union, deformity, degenerative changes - malunion of radius → *chronic subluxation* of the [[Distal radial ulnar joint dislocation|DRUJ]], leading to chronic pain and impaired movement
