• ABSTRACT
    • The purpose of this study is to describe long-term outcomes of the modified Jones procedure for pes cavovarus with claw hallux deformity. Jones originally described an isolated transfer of the extensor hallucis longus tendon. However, this technique does not correct and stabilize the claw hallux deformity. Therefore, this operation has been modified to include arthrodesis of the interphalangeal joint of the hallux, distal stump tenodesis of extensor hallucis longus with brevis tendon, and osteotomy of the base of the first metatarsal in cases of fixed or structural deformity. Twenty-four feet in twenty-one patients were evaluated with a 4-year average follow-up. Results were rated as good, fair, of poor based on correction of deformity, absence of pain, and metatarsophalangeal joint motion. Poor results were observed in 21% of feet and were related to first metatarsal dorsiflexion, pseudoarthrosis of interphalangeal joint fusion, and recurrent pain under the first metatarsal head.
