Infantile and juvenile lunatomalacia.

Abstract

Lunatomalacia or avascular necrosis of the lunate in children is a rare disease not described by Kienböck. It is somewhat surprising that the term Kienböck's disease has been used to describe this disease of the lunate in children. We report our experience in 13 cases and review the literature. In children under 12, the prognosis is very good after immobilization alone. Persistent symptoms may indicate surgery, probably radial shortening, in some older teenagers although the outcome appears better than in adults. We suggest the term lunatomalacia to describe this disorder, in recognition of the term originally used by Kienböck.
