The hallux varus deformity results from a dynamic imbalance of the
tendons that cross the first metatarsophalangeal joint. This condition most
frequently occurs after McBride-type operative treatment for hallux valgus.
A new procedure, developed to correct this imbalance, involves transferring
the extensor hallucis longus beneath the first intermetatarsal ligament
into the base of the proximal phalanx, along with an arthrodesis of the
first interphalangeal joint. This procedure in fifteen affected great toes
gave over-all satisfactory correction of the hallux varus deformity.
