Card Set Information
convex/cavity of 1st MCP joint
: concave on convex
: convex on concave
(for 2-5 it's all concave on convex)
femoral head is oriented which way
sup ant med
angle of inclination norms
coxa valga is > 125
vara is < 115
acetabulum faces which ways
inf ant lat
iliofemoral lig from where to where
AIIS to intertrochanteric line
lig or Bigelo
bands of iliofemoral / Y / lig of bigelow
: AIIS to distal intertrochangeric line
: AIIS to prox intertrochanteric line
iliofemoral lig does what?
limits ext and ER
lat band limits add
where to where
ischium, post acetabumulum --> greater troch
IR, abd, ext (ext bc it attaches so high that in ext it would be pulled forward)
lig around the femoral neck, helping hodl the head of femur in the acetabulum
ischiofemoral bursa is located where
can cause what pain pattern
btwn IT and glut max
pain in sciatic distributino
deep trochanteric bursa may hurt when? located where?
flexion and IR
btwn post lat greater troch and glut max
which arteries supply prox femur
med and lat femoral circumflex
femoral head gets blood from where?
foveal artery, which is a branch of the obturator artery
acetabulum gets blood from where?
sup and inf gluteal arteries
MCL taut/slack when?
prevents what? gives stability against what?
taut in ext
slack in flex
stability against valgus
(runs in same dire as ACL)
LCL taut/slack when? prevents what? stability against what?
taut in ext
slack in flex
stabil against varus
(runs in same dir as PCL)
arcuate popliteal lig from where to where?
Y shaped (w med and lat bands)
: post border of intercondylar area of tibia
: lat epicondyle of femur --> fib head
strenghtens posterolat capsule
oblique popliteal lig
where to where? does what?
lat post inf femur -->tendon from semimembranosus
strengthen post medial capsule
inferolat edges of patella --> lat borders of each meniscus
pulls menisci forward with extension
alar fold (knee)
from lat patella to med and lat fem condyles
keeps patella in contact w femur
infrapatellar fold - what is it for?
limits compression bc it's compressed by patella tendon in full flex
structures attaching to the med meniscus
medial meniscopatellar lig
structures attatching to the lateral meniscus
lat meniscopatellar lig
(not the LCL or lateral capsule)
motion of menisci - they follow which bone when?
follow tibia w flex/ext
follow femur w IR/ER
fibula rotation in PF/DF
PF -- IR
DF -- ER (fib glides sup and post)
plantar calcaneonavicular lig
sustentaculum tali --> navic
supports head of talus
helps maintain medial longitudinal arch
tightening of plantar fascia via toe ext --> supination of calcaneus and inversion of subtalar jt --> rigid lever for push off
tibial rotation in PF/DF
PF - ER as it glides post on talus
DF - IR as it glides ant on talus
open chain inversion - how does the calcaneus move on the talus?
add, sup, PF
closed chain inversion - movmnt of calc and talus?
sup of calc
talus glides lat w abd and DF
tibia does ER
(reverse for eversion, w tibia doing IR)
