The metatarsophalangeal joints (MTPJ) are the articulations in the forefoot between the heads of the metatarsals and the proximal phalanges 1.
Gross anatomy
The joint is formed by the articulation of the metatarsals with their adjacent proximal phalanges. They are condyloid synovial joints which allow for flexion, extension and limited adduction and abduction 2.
First toe
The metatarsophalangeal joint of the first toe is stabilised by a capsuloligamentous complex and collection of tendons. The capsuloligamentous complex is comprised of:
- fibrous capsule
- collateral ligamentous complex
- sesamoid-phalangeal ligaments (medial and lateral)
- intersesamoid ligament
- plantar plate
- extensor hood
Additional supporting structures:
- flexor hallucis brevis (medial and lateral heads)
- flexor hallucis longus
- abductor hallucis
- adductor hallucis
- extensor hallucis longus
- extensor hallucis brevis
LessLesser metatarsophalangeal joints
The lesser (second-to-fourth) metatarsophalangeal joints also have a capsuloligamentous complex which is comprised of 3:
- fibrous capsule
- collateral ligamentous
complexcomplexes (proper and accessory) - plantar plate
Additional supporting structures:
- flexor digitorum longus
- flexor digitorum brevis
- extensor digitorum longus
- extensor digitorum brevis
- flexor digiti minimi brevis
- abductor digiti minimi
- dorsal and plantar Interossei
- lumbricals
