This is where small bones in the wrist lose their blood supply and die causing pain and stiffness in wrist motion. This can lead to the bone collapsing and shifting the position of the surrounding bones.
Symptoms
Painful and swollen wrist
Pain or difficulty turning the hand
Tenderness
Stiffness
Eventually this will lead to arthritis
Cause
The exact cause is not known but it is through injury or through variations of the growth of the arm bones are the most likely causes
Treatment
Avoiding further trauma to area
In early disease, this may be aided by splinting
Anti-inflammatories can be used in the early stages
Surgery to excise the dead bones followed by joint leveling and revascularization (reestablishing the blood supply)
Prevention
Immediate attention of this condition can prompt earlier diagnosis and corrective measures to prevent further progression of the disease.
