the ______ ligament attaches just anterior and superior to the calcaneofibular ligament which partially overlies it on the lateral surface of calcaneus
lateral talocalcaneal ligament
there is a ligament to each of the 4 bones that articulate with the intermediate cuneiform. The ligaments are:
- dorsal cuneonavicular - two dorsal intercuneiform - dorsal cuneometatarsal
what structures are attached to the plantar surface of the cuboid?
(7) - long plantar ligament - short plantar ligament - plantar cuboideonavicular ligament - tibialis posterior - flexor hallucis brevis - plantar cuneocuboid ligament - two plantar cuboideometatarsals ligaments (one to 4th, one to 5th)
the shaft of the fourth metatarsals serves as origin for what muscles?
- lateral head of third dorsal interosseous - medial head of fourth dorsal interoseous - second plantar interosseous
what structures are on the plantar surface of the cuboid?
- peroneal sulcus - peroneal ridge - both sulcus and ridge course obliquely from posterolateral to anteromedial - peroneal sulcus lies distal to the peroneal ridge - tendon of peroneus longus lies either in the peroneal groove or against the anterior aspect of the peroneal ridge - deep fibers of the long plantar ligament attach to the peroneal ridge - superficial fibers of the long plantar ligament course over the tendon of peroneus longus
the posterior surface of the medial cuneiform is _______ and articulates with the navicular.
- concave - can be triangular, pear-shaped or quadrilateral
The anterior surface of the intermediate cuneiform has a ________ facet for its articulation with the ________ metatarsal.
- triangular - second metatarsal
the body of the talus is ____ in shape
cubical
_________ takes partial origin from the surface of the base of the 5th met.
flexor digiti quint
what structures attach to the plantar surface of the base of the second met:
- long plantar ligament - tibialis posterior - plantar cuneometatarsal ligament - plantar intermetatarsal ligament - adductor hallucis (oblique head)
Describe the head of the proximal phalanx of the great toe.
- flat vertically - articular surface trochlear; large and extends more plantarly than dorsally
= inferior, tapered end of the lateral surface of body of talus
- lateral process - has large triangular facet for the lateral malleolus - rough areas anterior and posterior to articular fact for attachment of anterior talofibular and posterior talofibular ligaments
the bases of the lesser toes have _______ facets for the metatarsal heads
oval
at times, an accessory muslce called abductor os metatarsi digit minimi also inserts ___________.
plantar surface of the base of the fifth metatarsal
The posterior surface of the second met base has a ____ facet for its articulation with intermediate cuneiform. The medial surface of the base of the second met has a _______ facet for its articulation with the medial cueniform. The lateral surface of the base has ____ facets for articulation with ________.
- triangular - small, oval (occasionally a second small oval facet, located anterior and inferior to the facet for the medial cuneiform is present - it is a pressure facet for first met and forms from contact between the bones. ) - two facets, one dorsal and one plantar. a ridge of bone separates each facet into demarcates. - the two anterior demarcates are for the third met. the two posterior demarcates are for the lateral cuneiform
what separates the navicular tuberosity from the plantar surface?
groove for tendon of tibialis posterior - groove is for continuation of the tendon of tibialis posterior beyond its attachment to the tuberosity
the posterior surface of the base of third met has a _______ facet for the lateral cuneiform. the lateral surface of the base has a ________ facet for the fourth met. Just inferior to this facet, there is a distinctive ____________ characteristic of the bone.
- triangular - small, oval - groove for the interosseous intermetatarsal ligament
what 3 tubercles might be on the lateral side of calcaneus?
- retrotrochlear eminence - peroneal tubercle - third tubercle (calcaneofibular tuberosity)
what are the bones of the medial arch?
fist three metatarsals all three cuneiforms navicular calcaneus talus
the ___ surface of the lateral cuneiform is the apex of the wedge. What muscles attach to this surface? What ligaments attach to this surface?
- plantar - muscles: flexor hallucis brevis and tibialis posterior - ligaments: plantar cuneocuboid, plantar cuneonavicular, plantar intercuneiform, plantar cuneometatarsal
the cuboid tuberosity has an ______ facet
- oval - over which there is a sesamoid bone (os peroneum) in tendon of peroneus longus
on the plantar surface of the first met, the two facets for the medial and lateral sesamoid bones are separated by a small ridge of bone, ___
- the median crista
what structures does the trochlea of talus articulate with?
(5) - tibial plafond (inferior surface of tibia) - medial malleolus of tibia - lateral malleolus of fibula - anterior (inferior) tibiofibular ligament - inferior transverse ligament, which is the deep portion of the posterior (inferior) tibiofibular ligament
The posterior surface of the lateral cuneiform is ____. It articulates with the ______.
- triangular - navicular
