Boutonniere deformity is a well-known deformity in the fingers, but may also occur in a lesser toe. The deformity is similar to that of a hammer toe and makes it difficult or impossible to straighten and bend the toe joint.

The most common cause of Boutonnière deformity is jamming or crushing the toe, injuring the extensor tendon in the process. It can also develop as a result of rheumatoid arthritis and other inflammatory disorders. The deformity may make walking or wearing shoes difficult.

The foot and ankle subspecialists at Lancaster Orthopedic Group may treat your Boutonniere deformity by splinting or casting the affected toe or with orthotics (shoe inserts). Surgery may be needed if the tendon has been severed, a bone fragment has been displaced, or splinting has not improved your condition.
