Wrist Injury Overview
The wrist is made up of the two bones of the forearm (the radius and ulna) and
eight carpal bones (scaphoid or navicular, lunate, triquetrum, pisiform, trapezium,
trapezoid, capitate, and the hamate). Many ligaments connect these bones to each
A sprain is an injury to the wrist ligaments without any evidence of bone
injury (that is, no broken bones or cracks in the bone). With a sprain, there is
usually only a partial tearing of the ligaments. In a severe wrist sprain, there
can be a complete tear.
A fractured or broken wrist means there is a break or a crack in one or more
of the bones of the wrist.
A strain is where there is a tearing of the muscle fibers in the area
surrounding the wrist.
