Bones of pelvis:
Joints of pelvis (2) / type
Sacroiliac - synovial

Pubic symphysis - fibrous, not synovial.
Which Sacroiliac joint is more easily torn?
Anterior - will result in high riding pelvis
Posterior SI joint protects:
Lumbosacral plexus
If you're going to fracture the Femoral Neck, where is it best to do so?
Lateral to the intertrochanter line - there's a larger blood supply so it heals better here.
3 surfaces articulate in the knee joint:
-Medial femoral-tibial
-Lateral Femoral-Tibial
Which meniscus in the knee is more commonly injured?
What does NOT participate in the knee joint?
Why can't the meniscus be repaired if it's torn in the inner 1/3rd?
There is no blood supply there.
Which ligament of the knee is most commonly torn? In who?
ACL - 3 times more common in women
Which ankle ligaments are more clinically significant?
Which ligament is most commonly sprained in the ankle?
ANTERIOR talofibular ligament; results in inversion of the ankle.
Tibial nerve
-supplies what
-Becomes what
-Supplies Posterior compartment
-Becomes Medial/Lateral plantar nerves of the foot.
Common Fibular nerve - injury will cause what?
Foot drop
What inherited disease causes foot drop like symptoms?
Charcot-Marie Tooth disease - loss of common peroneal function results in loss atrophy in anterior and lateral compartments.
Common fibular nerve becomes what 2 branches to supply:
-Superficial - lateral compartm
-Deep - anterior compartment
What supplies DORSUM of FOOT?
Superficial fibular nerve; after supplying the peroneal muscles, wraps by the lateral ankle.
Deep fibular nerve
Saphenous nerve
-Branch of femoral
-Cutaneous to medial lower leg
Sural nerve
Cutaneous branhces of Tibial (medial sural) and Common fibular (lateral Sural).
What does the sural nerve give innervation to?
The lateral, posterior, lower leg, and foot - except plantar and dorsum.
What gets innervation from the bottom of foot?
Tibial - medial/lateral plantars
Anterior compartment:
Nerve: deep fibular
Artery: Anterior tibial
Action: dorsiflexion
Anterior compartment muscles:
-Anterior tibialis
-Extensor digitorum longus
-Extensor hallucis longus
Lateral compartment:
Nerve: Superficial fibular
Artery: Fibular artery - located in posterior compartment though!
Action: Eversion/Dorsi
Posterior compartment muscles:
Peroneus longus and brevis
Superficial posterior comprtmnt:
Nerve: Tibial
Artery: Posterior tibial
Action: Antigravity, slight leg flexion due to gastroc
Muscles in Superficial posterior compartment:
Gastroc/Soleus -> plantarflex
Plantaris -> no action
Deep posterior compartment:
Nerve: Tibial
Arter: Posterior tibial
Action: Plantarflex/Inversion
Deep posterior compartment muscles:
-Posterior tibialis
-Flexor hallucis longus
-Flexor digitorum longus
For the following muscles name the nerve
Extensor digitorum brevis
Deep fibular nerve (same as for extensor digit longus)
Abductor hallicus and Flexor digitorum brevis:
Medial Plantar nerve
Abductor digiti minimi
Lateral plantar nerve
Quadratus plantae
(function of this?)
Lateral plantar nerve
-adjust the pull of flexor digitorum longus tendon toward heel)
Lumbricals - on what?
Ride on FDL tendons 2-5; 2 innervations don't need to know.
Flexor hallucis brevis
(inserts where)
Medial plantar nerve
-on 2 sesamoid bones
Adductor hallucis
(inserts where)
Lateral plantar nerve
-Both oblique/transverse heads insert on sesamoid bones.
Flexor digiti minimi brevis
Lateral plantar nerve
Lateral plantar nerve
Dorsal interossei action
Abduct (DAB)
Plantar interossei
Adduct (PAD)
