What is the descriptive term used for this somewhat malunited fracture?
Dinner fork deformity or bayonet deformity.
If a fracture is mal-united resulting in a dinner fork deformity, what functional limitations ensue and what treatment options exist?
In many instances the deformity is merely cosmetically unappealing, although limitation of wrist movement and pronation / supination may also be present. As a result in many cases, especially as the affected population is predominantly elderly, nothing needs to be done. If symptoms are severe or deformity distressing then an osteotomy and internal fixation can be performed.
The fracture has healed with a residual dorsal angulation.
