what attaches periosteum to bone?
what are different types of coalitions- fibrous? cartilaginous? osseus?
Coalition vs Bar?
most common coalition in the foot?
distal and middle phalanx of the 5th
most common coalition of the rear foot?
What is a Steida process
enlarged os trigonum
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
what layer does the FDL run
if you cut QP, what deformity results
4th and 5th digits become adductovarus
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.
What is the Master Knot of Henry?
Fibrous connection between FHL and FDL tendons
What structures attach to the fibular sesamoid?
Plantar metatarsal-phalangeal ligament
Lateral metatarsal-sesamoidal ligament
What structures in the Lisfranc joint are not connected by ligaments?
1st and 2nd met
what angle do ATFL and CFL create
whats bassett ligament?
ant inf tibofib ligament
another name for flexor retinaculum?
another name for superior extensore retinaculum
transverse crural lig
another name for inferior extensor retinaculum
cruciate crural lig
where does plantaris insert?
medial aspect of tendo Achilles into the calc
whats hoke tonsil
fibrour fatty plug in sinus tarsi
Sartorius, gracillus and semitendinosus (ant medial aspect of tib)
sesmoid in lateral head of gastroc
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
Does a neuroma lie dorsal or plantar to the deep transverse intermetatarsal ligament?
Where do these muscles run in relation to the deep transverse intermetatarsal ligament?
Interossei – dorsal
Lumbricals – plantar
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
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
What are the branches of the femoral nerve?
Nerve to femoral artery
Small muscular branch to pectineus
Anterior division (cutaneous)
Anterior femoral cutaneous
Nerve to sartorious
Intermediate femoral cutaneous nerve
Medial femoral cutaneous nerve
Posterior division (muscular)
Medial crural cutaneous nerve
Nerve to rectus femorus
Nerve to vastus medialus
Nerve to vastus intermedialus
Nerve to vastus lateralus
What are the branches of the femoral artery?
Superficial epigastric artery
Superficial circumflex iliac artery
Superficial external pudendal artery
Deep femoral (profunda femoris) artery
Medial femoral circumflex artery
Lateral femoral circumflex artery
Descending genicular artery
Femoral artery continues as the popliteal artery
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
What are the sources of blood supply to the talus?
Superior surface of head and neck – artery of sinus tarsi and branch from anterior tibial
artery or dorsalis pedis
Medial side of body – artery of tarsal canal and posterior tibial artery
Lateral turbercle – anastamosis of branch of peroneal artery with medial calcaneal branch
