| Carpal Slab Fractures |  |
|
|
| Slab fractures extend from one articular surface to another articular surface. In the carpus, slab fractures occur in both frontal and sagittal planes. The most common fracture is a frontal fragment of the radial facet of the third carpal bone, followed by fractures of the intermediate facet and both facets of this bone. When a frontal slab fracture of the third carpal bone occurs without joint collapse, it is considered to be “routine.” The treatment is lag screw fixation (done arthroscopically), and many of these horses return to full athletic activity. |
| Collapsing slab fractures also occur in the carpal bones. The fracture typically involves the third carpal bone, but there is displacement and comminution to the extent that one row of carpal bones tends to collapse. If untreated, the leg progresses to a carpal varus conformation and laminitis develops in the opposite forelimb. Collapsing slab fractures require internal fixation, augmented with cast fixation for up to 6 wk, to minimize later collapse of the joint. |
