Boundaries of the femoral triangle
|
Superiorly: Inguinal ligament
Laterally: Sartorius Medially: Adductor Longus |
|
Spatial relation of the femoral nerve to the femoral sheath
|
immediately lateral
|
|
spatial relation of the femoral vein to the femoral artery
|
immediately medial. both are in femoral sheath
|
|
contents of the femoral canal
|
deep inguinal lymph nodes
|
|
ligament that serves as the medial boundary of the femoral ring
|
lacunar ligament
|
|
structures that course through only a portion of the adductor canal
|
saphenous nerve
nerve to vastus medialis descending genicular vessels |
|
muscle that forms the floor of the popliteal fossa
|
popliteus
|
|
muscle that serves as chief flexor at the hip joint
|
iliopsoas
|
|
muscle that prevents the pelvis from tilting when walking
|
gluteus medius
|
|
muscle that extends the leg
|
quadriceps femoris
|
|
muscle that unlocks the knee joint
|
popliteus
|
|
condition that occurs due to disruption of nerve supply to the tibialis anterior
|
"foot drop"
nerve supply to tibialis anterior and other muscles in anterior leg compartment is the deep fibular nerve |
|
chief invertors of the foot
|
tibialis anterior
tibialis posterior |
|
chief evertors of the foot
|
fibularis longus
fibularis brevis |
|
Function of ACL
|
prevents posterior displacement of femur on tibia
|
|
Laxity of which ligament can produce a positive valgus maneuver
|
MCL
|
|
most commonly injured ankle ligament
|
anterior talofibular
|
|
If this ligament is compromised, leads to "flat foot"
|
plantar calcaneonavicular ligament. AKA "spring" ligament
|
|
major artery to the head of the femur in an adult

common fibular
|
|
avulsion fracture of the 5th metatarsal will damage which tendon?
|
tendon of fibularis brevis
|
|
Describe the innervation of the adductor magnus
|
Anterior fibers: obturator
Posterior fibers: tibial branch of sciatic |
|
tarsal tunnel syndrome is due to an affliction of which nerve?
|
tibial nerve
|
|
which nerve provides cutaneous innervation to the medial side of the foot
|
saphenous nerve (L4)
|
|
which nerve provides cutaneous innervation to the lateral side of the foot
|
sural nerve (S1)
|
|
which nerve provides cutaneous innervation of the heel
|
tibial nerve
|
|
which nerve provides cutaneous innervation to the dorsal aspect of the web between the 1st and 2nd toe?
|
deep fibular nerve
|
|
which nerve provides cutaneous innervation to most of the dorsum of the foot

|
L4
|
|
dermatome to the small toe
|
S1
|
|
spinal level of the patellar reflex
|
L4
Both afferent and efferent limbs of the reflex arc travel in the femoral nerve. result in contraction of the quadriceps femoris |
|
spinal level of the achilles reflex
|
S1
Both afferent and efferent limbs arc travel in the tibial nerve. Result in contraction of the triceps surae (gastrocnemius + soleus) |
|
Locking of the knee when walking suggests injury to what structure?
|
Meniscus
|
|
The "terrible triad" consists of injuries to:
|
MCL
ACL Medial meniscus |
