Smith fracture
Robert Smith described the Smith fracture in 1847. An impact to the dorsum of the hand or a hyperflexion or hypersupination injury is thought to be the cause. A Smith fracture is usually called a reverse Colles fracture because the distal fragment is displaced volarly. It is often described as a garden-spade deformity. The ulnar head can be displaced dorsally .
Anteroposterior (AP) and lateral views of the wrist involve a minimal examination. The criteria that are used to evaluate Colles fractures also apply to Smith fractures.
Table 4. Thomas Classification of Smith Fractures
Type | Description |
I | Most stable, extra-articular, transverse distal radial fracture with palmar and proximal displacement |
II | Barton type, palmar-lip fracture of the distal radius with dislocation of the carpus |
III | Unstable, oblique, juxta-articular fracture of the distal radius and tilted palmar |
The complications of Smith fractures are similar to those of Colles fractures.
smith's frx is also called as the reverse colles fracture .
