Mod 3 - Lower Limb Flashcards
Articular surface of ilium
articulates with sacrum
Bone marrow biopsy(test question)
at the iliac crest
Bone marrow transplantation
marrow can be injected into the vein to add new bone borrow to body if a match
pudendal nerve(know it) go out of
greater sciatic foramen and into lesser sciatic foramen
male palvis
deeper and narrower
pubic arc is narrow
android
Female pelvis
wider and shallower
pubic arc is wider
gynecoid
Pelvic brim is border between
greater and lesser pelvis
Cephalic position
3rd trimester head down and balled up baby
Breech
not cephalic position
Transverse diameter
baby head side compared to horizontal
true conjugate
diagonal conjugate – 1.5cm = usually 11.5cm
The head rotates 90 degrees during delivery which is why
diameters are important
Intercristal is from the two outermost points of
the hip sides laterally
External conjugate
inferior border of pubic synthesis to spinous process of L5
Folia capitis inserts here on the head of the femur
also the acetabulum
Angle of inclination
126 degrees in adults and 145 degrees in children, 120 degrees in old age
the angle of the femur head off the bone(becomes bent more over time)
The great the abnormal angle the greater chance of injuring the meniscus or other injuries
Interoseus membrance between tibia and fibular is a
continuous joint
Periostrium has nerves and blood vessels(check this)
does not go over the articular surfaces
periostitus - Oschlatters Disease(know this)
avulsion – bone can detach
Pelvic inlet:
transverse diameter
13.5-14 cm
Pelvic inlet:
Oblique diameter I
12-12.5 cm
Pelvic inlet:
Oblique diameter II
11.5-12 cm
Pelvic inlet:
Anatomical conjugate
12 cm
Pelvic inlet:
True conjugate
11.5 cm
Pelvic inlet:
Diagonal conjugate
13 cm
Pelvic outlet:
Straight conjugate
9.5-10 cm
Pelvic outlet:
median conjugate
11.5 cm
Pelvic outlet:
interspinous diameter
not less than 9.5 cm
intercristal distance
29 cm
External conjugate
20 cm
Congenital dislocation of the hip
Common birth defect, more in female
infants.
Either the acetabulum fails to form
completely or the ligaments of the hip
joint are loose.
Treatment: splint or diaper, or harness of
straps to hold femur in its proper position
Metatarsal stress fractures
As a result of repetitive stress
on foot.
2nd and 3rd metatarsals are
mostly affected
Treatment: rest and wearing
stiff or well cushioned shoes.
