Syndesmosis
synchondrosis
synostosis

18

Coalition vs Bar?

Coalition=intraarticular
Bar=extra-articular

19

most common coalition in the foot?

distal and middle phalanx of the 5th

20

most common coalition of the rear foot?

talocalcaneal

21

What is a Steida process

enlarged os trigonum

22

What are the plantar muscle layers of 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

23

what layer does the FDL run

2nd

24

if you cut QP, what deformity results

4th and 5th digits become adductovarus

25

how does EDL attach to 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.

26

What is the Master Knot of Henry?

cruciate crural lig

34

where does plantaris insert?

medial aspect of tendo Achilles into the calc

35

whats hoke tonsil

fibrour fatty plug in sinus tarsi

36

38

what forms the sural nerve

Medial sural cutaneous nerve – branch of the tibial nerve
Sural communicating branch – branch of the lateral sural cutaneous nerve, which originates from
the common peroneal nerve

39

Does a neuroma lie dorsal or plantar to the deep transverse intermetatarsal ligament?

plantar

40

Where do these muscles run in relation to the deep transverse intermetatarsal ligament?

Interossei – dorsal
Lumbricals – plantar

41

What layers of the foot do the plantar nerves run?

Medial plantar nerve – in the 1st layer (between FDB and abductor hallucis)
Lateral plantar nerve – between the 1st and 2nd

42

What is the innervation to the plantar muscles of the foot? Blood supply?

Never LAFF at A FAD)
N – medial plantar Nerve
L – 1st Lumbrical
A – ABH
F – FHB
F – FDB (innervated by both medial and lateral plantar nerves)
A – medial plantar Artery
F – FDB
A – ABH
D – 1st Dorsal interossei

43

What are the branches of the femoral nerve?

Nerve to femoral artery
Small muscular branch to pectineus
Anterior division (cutaneous)

45

T race the path of a drop of blood from left ventricle to the hallux

Ascending aorta → aortic arch → descending aorta → thoracic aorta → abdominal aorta →
common iliac artery → external iliac artery → femoral artery → deep femoral artery →
popliteal artery → anterior tibial artery → dorsalis pedis → 1st dorsal metatarsal artery →
1st dorsal common digital artery → 1st dorsal proper digital artery
