The cuneiform bones are 3 bones (medial, intermediate and lateral) in the midfoot at the top of the arch of the foot. Buschke disease of the cuneiform bones is a very rare disorder of one or more of these bones due to a disruption of blood supply to part of the bone.
The most common ages are ages 5-6 years with boys more often affected than girls. Pain and limping are the most common symptoms.
Treatment is best aimed at reducing physical activity and the use of foot supports.
