Acquired hallux varus deformity of either the static or the dynamic type
results from surgery to correct hallux valgus deformity and the
accompanying bunion. The dynamic type is disfiguring, uncomfortable, and
disappointing to the patient and surgeon alike. Linear as well as
rotational forces are at work to produce the deformity. When recognized
early, before fixation of the first digit has occurred in the deviated and
clawed position, resection of the base of the proximal phalanx will correct
the deformity. More radical treatment is required in the patient who is
treated late. The experience with seven feet of five patients with acquired
hallux varus deformity is presented here.
