what layer does the FDL run

24
Q

if you cut QP, what deformity results

A

4th and 5th digits become adductovarus

25
Q

how does EDL attach to phalanxes

A

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.

another name for inferior extensor retinaculum

A

cruciate crural lig

34
Q

where does plantaris insert?

A

medial aspect of tendo Achilles into the calc

37
Q

fabella?

A

sesmoid in lateral head of gastroc

38
Q

what forms the sural nerve

A

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
Q

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

40
Q

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

A

Interossei – dorsal

Lumbricals – plantar

41
Q

What layers of the foot do the plantar nerves run?

A

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

42
Q

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

A 
Never LAFF at A FAD)
N – medial plantar Nerve
L – 1st Lumbrical
