Kienboeck Disease is an acquired bone disorder. Abnormalities of the
lunate bone in the wrist develops following an injury or inflammation.
Recurrent pain and stiffness occur in conjunction with thickening, swelling
and tenderness in soft tissue overlying the lunate bone. The range of motion
in the wrist may become limited.
Symptoms
Kienboeck Disease is characterized by degenerative changes in the lunate bone
of the wrist. Softening, deterioration, fragmentation or compression of the
affected bone can occur. These changes may produce pain, swelling,
tenderness, thickening and/or stiffness in the overlying tissues of the
wrist. The range of motion may become restricted. Healing occurs through
formation of new bone in some cases.
Causes
Kienboeck Disease is caused by inflammation or injury of the wrist.
Affected Population
Kienboeck Disease usually begins during childhood and seems to affect females
more often than males.
Related Disorders
Symptoms of the following disorders can be similar to those of Kienboeck
Disease. Comparisons may be useful for a differential diagnosis:
Carpal Tunnel Syndrome is a condition caused by compression of peripheral
nerves in the wrist, affecting one or both hands. It is characterized by a
sensation of numbness, tingling, burning and/or pain in the hand and wrist.
Persons affected by this disorder may be awakened at night with the feeling
that the hand has "gone to sleep". Various other diseases may occur in
conjunction with this condition. With timely treatment, the prognosis in
most cases is favorable. (For more information on this disorder, please
choose "Carpal Tunnel" as your search term online.)
Sudeck's Atrophy, also known as post-traumatic osteoporosis, is marked by
an acute atrophy of the bones. The wrist and ankle bones are most commonly
affected, following a slight injury such as a sprain.
Juvenile Osteoporosis is marked by a porous condition or atrophy of bone
tissue beginning before puberty. The exact cause has not been identified.
This condition can lead to pain or fractures in many bones of the body
including the wrist. Spontaneous remission may occur within several years.
Therapies: Standard
The treatment of Kienboeck's Disease may involve surgery on the lunate bone.
Arthroscopic, CT scan and/or x-ray imaging may be used for diagnosis. If
inflammation of the wrist has occurred, drug treatment may be recommended.
Other treatment is symptomatic and supportive.
Therapies: Investigational
