Abstract
|
|
|
Dislocation of first metatarsophalangeal joint is a rare condition. Anatomically, the head of first metatarsal is stabilized by various soft tissue structures associated with the sesamoid bones. When the metatarsal head was entrapped
underneath
the
'sesamoid complex', it might be impossible to gain reduction via closed method.
We experienced a case of dorsal dislocation of first metatarsophalangeal joint and associted dislocation of tarsometatarsal joint in a 32 year old man who was injured by fall from height. Closed reduction failed even under spinal
anesthesia.
Open
reduction via medial approach revealed 'buttonholing' of the metatarsal head under the sesamoid complex, which had made colsed reduction impossible. Concerning about the rarity and anatomical characteristic of these injuries, we report this
cases
with reviewing of the literatures.
