How is a bunion diagnosed?
When the patient stands with the weight evenly distributed,
the bunion is evident as a bony growth protruding from the
metatarsal head
at the base of the great toe, which is angled in toward the other toes
. Sometimes the pressure against the second toe causes it to deform into a
"hammer toe"
. This condition may be more painful than the bunion itself, and can occasionally cause the second toe to partially dislocate. This can lead to the formation of a callus (
transfer lesion
) under the metatarsal head, which can be very painful. X-rays can reveal the extent to which the second toe is dislocated.
