There are 8 carpal bones in the human wrist, arranged in 2 rows. Whenever there is a suspicion of a fracture carpal bone, patients should be advised to wear a splint, as not all fractures are detected on an initial X-ray (Cooney, 2011).
The motion of the wrist occurs between the radius /ulna (forearm bones) and carpal bones.
Injury is normally caused by a fall onto an outstretched hand; fracture hardly occur through a direct blow (Cooney, 2011).
The fracture normally requires rest in plaster. Carpal instabilities may develop early or late after a carpal injury. Physiotherapy will aim to strengthen the muscles of the wrist to stabilise these instabilities.
