Mod2- Skeleton of lower limb Flashcards
what is a common area of fracture on the femur
neck
the tibial tuberosity is what kind of ossification center
secondary
what is commonly affected in a bumper fracture
proximal lat tibial condyle and plateu
what two bones make up the hindfoot
talus
calcaneous
what is the main bone for weight transfer in the foot
talus
what sustains the arch of the foot and head of talus
sustentaculum tali
what toe doesnt have 3 phalanges
great toe
what is the triradiate cartilage and at what age does it fuse
fusion of the ischium, ilium and pubis
13-15
at what age does the ossification of the ishiopubic ramus occur
6-8
at what age does the hip bone completely ossify
20-25
what is the lacunar lig made up of
reflected inguinal lig fibres
what does the pectineal lig made up of and do
lacunar lig will continue to make the pectineal lig to connect to sup pubic ramus
what divides the vascular lacunea from the nueromuscular lacuna
iliopectineal arch
what two muscles run thru neuromuscular lacuna and what nerve
iliacus/psoas and femoral nerve between the groove of them
contents of vascular lacuna from med to lat
- deep inguinal lymph node (femoral ring)
- femoral vein
- Femoral artery
- femoral branch of genitofemoral n
what travels thru the obturator canal
obturator nerve, artery and vein
Sacrotuberous lig attachments (4)`
PSIS
Post sacroiliac lig
Lower lat sacral crest
lateral margins of lower sacrum and upper coccyx
Sacrospinous lig attachments
ischial spine to lat margin of sacrum, coccyx ant.
what condyle of the femur has the more prominant epicondyle
medial (adductor tubercle)
where is the linea aspera femoris located
on post shaft of femur (roughness)
Difference CAM and Pincer impingment
CAM- misshapen femoral head/ or femoral neck
Pincer- hip socket covers too much of the femoral head
what is slipped capital femoral epiphysis and what age is it most common
weakend epiphyseal growth plate and femoral head slips away from femoral neck
-10-17 y old (more common in male)
what is the most frequent site of a tibial fracture
junction of middle and inferior thirds
On patella where does; quad femoris tendon attach Vastus intermedius and rectus femoris Lateralis Medialis
qf- base
lat- medial border
intermed-lat border
med- apex
what is the only bone in the foot w no muscular or tendinous attachments
talus
how many articular facets on the talus
6
ant- joins navicular
ant/middle/post calcaneal
medial + lateral for med and lat malleoli
what is the taral sinus between
calcaneal sulcus and talar sulcus
fibular trochlea- where is it located and what passes by it
lateral surface of calcaneous
fibularis longus pases sup to it
what attaches to the medial calcanea tuberosity
abductor hallucis abductor digiti minimi flexor digitorum brevis flexor retinaculum plantar aponeurosis
what is freiberg disease
collapse of the articular surface of the 2nd metatarsal head
what is os trigonum
small secondary ossification of the talus fails to unite w the body of the talus
What are the palpable features anteriorly
ASIS Pubic crest/symphysis Patella Abductor tubercle Ant tibia Nerdy Tubercle Tibial tuberosity and tibia Lat + Med malleolus Tuberosity of 5th tuberosity of navicular (med)
what are the palpable features post
PSIS ischial tub greater trochanter Med + lat epicondyle/condyle head/ neck of fib med + lat malleolus calcaneal tub tuberosity of navicular
