35
What are the plantar muscle layers in the foot from superficial to deep
1) abductor hallucis, flexor digitorum brevis, abductor digiti minimi 2) quadratus plantae, 4 lumbricals 3) flexor hallucis brevis, adductor hallucis, flexor digiti minimi 4) 3 plantar interossei, 4 dorsal interossei
36
What layer of the foot does FDL run
2nd layer- it is the origin of the lumbricals and the insertion of QP
37
What deformity will result from cutting QP
digits 4 and 5 will become adductovarus
38
How is EDL attached to the proximal phalanxes
sling wraps around capsule which attaches to plantar plate, DTML, and flexor tendon sheath thus attaching to plantar proximal phalanx. No direct insertion to proximal phalanx
39
What is the origin and insertion of the capsularis tendon
origin- EHL muscle or tendon Insertion- first MPJ capsule
40
What is the Master Knot of Henry
fibrous connection between FHL and FDL
41
What structures attach to the fibular sesamoid (6)
- plantar MTP ligament - lateral met-sesamoid ligament - Intersesamoidal ligament - phalangeal-sesamoidal ligament - FHB tendon - ADH tendon
42
Are the sesamoids capsular or extra-capsular
capsular
43
What is the Lisfranc ligament
attaches lateral aspect of medial cuneiform to medial base of 2nd metatarsal
44
What structures in the Lisfranc joint are not connected by ligaments
1st and 2nd metatarsals
45
What is the spring ligament
Plantar calcaneonavicular ligament
46
What ligaments compose the bifurcate ligaments
- dorsal calcaneonavicular | - calcaneocubiod ligaments
47
Which is stronger-lateral ankle ligaments or the deltoid ligaments
deltoid ligament
48
What are the components of the deltoid ligaments
Superficial- tibionavicular, tibiocalcaneal, posterior tibiotalar Deep- Anterior tibiotalar
49
What tendons pass over the deltoid ligament
Tibialis posterior and FDL
50
What are the lateral ankle ligaments
anterior talofibular, calcaneofibular, posterior talofibular
51
What angle do the ATFL and CFL create
105 degrees
52
What is the strongest lateral ankle ligament
posterior talofibular
53
Which ankle ligaments are exra-capsular which are capsular
calcaneofibular ligament is extra capsular all others are capsular
54
What tendons pass over the lateral ankle ligaments
PB and PL
55
what ligaments support the ankle syndesmosis (3)
- AITFL - PITFL - interosseous tibiofibular ligament
56
What is the Bassett ligament
AITFL
57
what is another name for the flexor retinaculum
laciniate ligament
58
what is another name for the superior extensor retinaculum
transverse crural ligament
59
What is another name for the inferior extensor retinaculum
cruciate crural ligament
60
Where does plantaris insert
medial aspect of tendo-Achilles into the calcaneus
61
What is the incidence of peroneus quartus

67
Does a neuroma lie dorsal or plantar to the deep transverse intermetatarsal ligament
plantar
68
Where do these muscles run in relation to the deep transverse intermetatarsal ligament - Interossei - lumbricals
Interossei- dorsal lumbricals- plantar
69
What layers of the foot do the plantar nerves run
Medial plantar- in the first layer Lateral plantar nerve- between 1st and 2nd
70
What do the medial plantar nerve and artery supply
Never LAFF at A FAD - Medial plantar Nerve - 1st Lumbrical - ABH - FHB - FDB medial plantar Artery - FDB - ABH - 1st Dorsal interossei
