Abstract
Dislocation of multiple metatarsophalangeal joint is an uncommon injury. The mechanism of injury is a high energy force distal to proximal with foot in hyperextension at the metatarsophalangeal (MTP) joint. The acute hyperextension of the toe at the moment of injury causes avulsion of the plantar part of the capsule from the junction of head and neck of the metatarsal. If the collateral ligaments remain intact, they maintain the locked fibrocartilaginous plate over the dorsum of the head of the metatarsal, making closed reduction impossible. We report a case of simultaneous 1st and 2nd MTP joint open dislocation. In the present case, we chose the plantar approach utilizing the already present plantar wound. At 18 months post-operative follow-up, there was no instance of redislocations or signs of avascular necrosis of head of metatarsal.
