deep transverse metatarsal ligament
Which is the shortest metatarsal? Which is the longest?
shortest- 1st met
longest- 2nd met
What 2 tendons attach to the base of the 1st met?
- tibialis anterior- attaches to the medial surface of the base
- peroneus longus- attaches to the lateral surface of the base
(both attach inferiorly near the plantar surface)
What two ligaments attach to the base of the 1st met?
dorsal and plantar cuneometatarsal ligaments
what muscle is attached to the shaft of the 1st met plantarly?
the medial head of the 1st dorsal interosseous muscle
on which bone are the sesamoids located?
1st met- has medial and lateral facets for sesamoid boines
the two facets for the sesamoid bones on the 1st met are separated by a small ridge of bone called what?
median crista
what does teh base of the 2nd met look like?
triangular shaped with the apex directed plantarly
describe the medial surface of teh base of teh 2nd met. how many facets are there? What do they articulate with?
1 small, oval facet for the medial cuneiform
describe the lateral surface of the base of the 2nd met. how many facets are tehre? What do they articulate with?
2 facets- one dorsal, one plantar separated by a ridge of bone
- the 2 anterior demarcates are for the 3rd met
- the 2 posterior demarcates are for the lateral cuneiform
what ligaments attach to the dorsal surface of the base of the 2nd met?
- dorsal intermetatarsal ligament to the 3rd met
2. three dorsal cuneometatarsal ligaments, one from each cuneiform
what structures attach to the plantar surface of the base of the 2nd met?

interosseous intermetatarsal
interosseous cuneometatarsal
what ligament attaches to the medial surface of the base of the 2nd met?
Lisfranc’s ligament
Describe the lateral surface of the 3rd met.
has a small oval facet for articulation with the 4th met
