Traumatic Hallux Varus Treated by Minimally Invasive Extensor Hallucis Brevis Tenodesis

Abstract

A case of traumatic hallux varus due to avulsion fracture of the lateral side of the base of proximal phalanx was reported. The lateral instability of the first metatarsophalangeal joint was believed to be due to the disruption of adductor hallucis function. It was successfully managed by minimally invasive extensor hallucis brevis tenodesis.

Arthroscopic Arthrodesis of the First Metatarsophalangeal Joint in Hallux Varus

“…Joint-preserving surgery, including medial soft tissue release, metatarsal osteotomy, and tendon transfer, can be considered in flexible deformity without degeneration of the first metatarsophalangeal joint. 2 , 3 , 4 , 5 , 6 , 7 First metatarsophalangeal arthrodesis is indicated in cases of inflammatory arthritis, avascular necrosis, osteoarthritis, neuromuscular disorder, or failed previous hallux varus corrective surgery. 1 , 3 , 8 , 9 , 10 Classically, arthrodesis is performed in an open manner with extensive soft tissue dissection.…”
