Metatarsophalangeal joints – ligaments
Collateral ligaments
Plantar ligaments
Deep transverse metatarsal ligaments
Collateral ligaments (metatarsophalangeal)
- Limits: flexion
- Prevents: adduction and abduction in flexion
Plantar ligaments (metatarsophalangeal)
- Forms part of the articular surface
- Limits: extension
Deep transverse metatarsal ligaments (metatarsophalangeal)
- Keeps the metatarsal heads together
- Important in weight bearing
