Stabilization of first metatarsophalangeal instability with plantar plate tenodesis.

First metatarsophalangeal instability is an uncommon condition. It is resulted from disruption of the capsular-ligamentous complex, e.g. after dislocation of the hallux metatarsophalangeal joint or after turf-toe injury. The patient will experience pain with push-off and hallux rigidus type of symptoms. We present a technique to stabilize the first metatarsophalangeal joint by anchoring the plantar plate to the extensor hallucis longus tendon.
