Kienbock’s disease causes one of the bones in the wrist (lunate bone) to slowly break down due to low blood supply. This process is called osteonecrosis. Symptoms include pain, swelling, limited movement, and decreased grip strength. The symptoms usually start in adulthood, but can occur at any age. Kienbock’s disease usually slowly gets worse over time. The underlying cause of Kienbock’s disease is unknown. Diagnosis is made by imaging studies such as an MRI or CT scan. Treatment aims to relieve pressure and restore blood flow within the bone, and includes both surgical and non-surgical methods.
