Kienböck disease

Osteochondrosis or slow degeneration of the lunate bone of the wrist, usually resulting from trauma. Radiographic evidence includes sclerosis and collapse of the lunate bone. Treatment goals are to reduce pain, maintain motion, and prevent carpal collapse and ultimately arthritis. Untreated, it may result in loss of ulnar deviation

Kienbock's disease, also known as lunatomalacia, was first described in the literature by Robert Kienbock in 1910 as ligamentous trauma to the lunate resulting in the interruption of internal arterial supply to the bone.
In 1910, Kienbock theorized that lunatomalacia was a result of traumatic rupture of the ligaments surrounding the lunate with associated disruption of the internal blood supply to the lunate.
