L4: Osteology of Lower Extremity Flashcards
femur neck is vulnerable to ?
shear forces
especially in older women
femur trochanters
lip-like projections lateral to head and neck of femur
lesser = post
both serve as muscle attachment sites
intertrochanteric line
low
rough line
joining 2 trochanters on anterior surface
intertrochanteric crest
more distinct
heavier crest joining 2 trochanters on post surface
quadrate tubercle
attachment for quadratus femoris muscle
located on intertrochanteric crest
femoral condyles
articular surfaces for tibial plateaus
on post femur
patellar surface
distal anterior depression
between 2 femoral condyles
formation of the prominent linea aspera
convergence of 2 lines near mid shaft of femur
spiral line
continuation of intertrochanteric line
forms medial lip of linea aspera
what forms the lateral lip of linea aspera?
the heavier line from gluteal tuberosity
the 2 lines of the anterior femur diverge to form ?
the lateral and medial supracondylar lines
popliteal surface
between 2 supracondylar lines
forms part of the bed of the popliteal fossa
adductor tubercle
atrial attachment of adductor magnus
located on medial epicondyle
intercondylar fossa forms part of ?
post boundary of popliteal fossa
lateral boundary of linea aspera
continuation of gluteal tuberosity
inferiorly becomes lat supracondylar line
medial boundary of linea aspera
continuation of pectineal line
inferiorly becomes medial supracondylar line
angle of inclination in child vs adult vs old age
45 vs 126 degrees
vs 120 degrees
tibia blood supply
poor blood supply
thus slow healing
proximal end of tibia
very broad
consists of 2 shallow concave surfaces
intercondylar eminence of tibia
collection of small processes to which attach ligaments and menisci
fits into intercondylar fossa of femur
interosseous border is the attachment site for ?
interosseous memb between tibia and fibula
tibial tuberosity
process on prox ant surface
palpable from surface
forms attachment site for patellar ligament
soleal line
line on post surface of tibia
curves from below lat condyle to medial side of post surface
attachment site of soleus muscle
medial malleolus
distal tibia
large process that extends inferiorly
participates in formation of ankle joint w/ talus
