A hammertoe is a common deformity of the lesser toes (toes 2,3,4 or 5) in which the toe becomes "bent" over time which makes it look like a hammer.  At first, the toe deformity is flexible.  However, the longer the deformity is present, the more rigid it becomes.  As time goes on a corn or callous may form on the end or top of the toe and may cause a callous on the ball of the foot.  This may be completely painless but in some people it will be a source of discomfort.  In a diabetic patient it may result in an opening of the skin called an ulceration.

Hammertoes are caused by your foot type and tendon imbalances.  Often it is associated with a bunion deformity.  Bunions may need to be addressed at the same time.  Shoes may also contribute to the hammertoe deformities.

Treatments can include shoes with a higher, softer toebox, roomier shoes, padding (such as moleskin), strapping and in severe cases surgery may be the best treatment.  If surgery is involved, a piece of bone is removed to allow the toe to "straighten".  A pin or implant may be used depending on your surgeon's preference.
