Subluxation of the Second Metatarsophalangeal Joint with Associated Hallux Abducto Valgus in a Dancer

Abstract

Second metatarsophalangeal joint (MTPJ) instability can be a very painful and disabling foot disorder for dancers. The purpose of this case report is to review an incident where a dance instructor sub-luxed her second MTPJ after performing a specific tap dance step. This second MTPJ subluxation was treated surgically via a flexor digitorum longus tendon transfer. The dance instructor also had underlying forefoot pathology consisting of hallux abducto valgus (HAV) and a second hammertoe. These deformities were also addressed at the time of surgery. This patient had a good surgical outcome and was able to return to her dance instruction.
