The deformity of the hallux that is described in this article is most probably more common than we realize and is often seen in patients with mycotic nails and subungual exostosis. This pathology is easily corrected with a tenotomy-capsulotomy at the level of the distal interphalangeal joint. This procedure, when accomplished as described, does not affect the function of the hallux at the level of the metatarsophalangeal joint.
