Tibial sesamoid planing for intractable plantar keratoses.

Partial tibial sesamoidectomy or sesamoid planing is an alternative to complete sesamoidectomy or nonoperative maintenance of a plantar keratosis. It can be performed through a very small incision and is a relatively uncomplicated, yet effective, procedure for relieving the effects of abnormal shearing forces from a prominent or malpositioned medial sesamoid. A retrospective study of 13 patients extending for 10 years representing 17 procedures was conducted.
