peroneus longus tendon insertion
first metatarsal and medial cuneiform
insertion of peroneus brevis
base of the fifth metatarsal
avulsion of what tendon results in avulsion of the fifth metatarsal
peroneus brevis
what encapsulates the peroneal tendons
the superior peroneal retinaculum
what tendons does the superior extensor retinaculum encase?
tibialis anterior, extensor hallucis longus, extensor digitorum longus Tom’s Harry Dick
what is a Chopart sprain?
injury of the talonavicular ligament
FDL and FHL cross and form the:
master knot of henry
what is the bifurcate ligament
Y-shaped ligament originates from the dorsal aspect of the calcaneus and extends to the cuboid and navicular
how many plantar calcaneocuboid ligaments?
two. one short and one long
What is the strongest portion of the lisfranc ligament
interosseous
how many slips are there of the plantar fascia?
three: medial, central and lateral fascicles/cords
what causes osteochondral lesion on the lateral tibial dome?
forced inversion (shearing of the talar dome on the fibula)
spring ligament is a group of ligaments that connects the
calcaneus and navicular
Ligaments of the spring ligament
superomedial, medioplantar oblique, inferoplantar
structures responsible for maintaining the arch of the foot:
spring ligament and posterior tibial tendon
what courses under the sustentaculum tali?
FHL
What tendon courses through a groove in the steida process?
FHL
number of layers of the deltoid ligament
two, deep and superficial
parts of the superficial deltoid ligament
tibionavicular (TNL) tibiospring (TSL) tibiocalcaneal (TCL)
parts of the deep deltoid ligament
anterior tibiotalar ligament (ATTL); posterior tibiotalar ligament (PTTL)
