Week 2 Flashcards
line along shaft of femur name
linea aspera
Two muscles that insert on the ITB
gluteus maximus and tensor fascia lata
Snapping hip syndrome
Sensation felt on forward and backward movement of ITB across the greater trochanter
VMO (___________) is important because
vastus medialis obliqus, dynamic stabiliser of the patella
Clinical note of femoral canal?
femoral hernia can arise
Adductor canal boundaries
1) Anterior– Vastus medialis
2) Posterior– Adductor longus above, adductor magnus below
3) Medial– strong fibrous membrane between the anterior & posterior walls and is covered by Sartorius
Varicose veins are?
veins which have dysfunctional valves allowing backflow and distorting pressure, leading to a abnormally shaped blood vessel
What is a fovea
A depression
What does the centre edge angle of the acetabulum measure? Where is it measured from??
the “roof” over the femoral head (larger = more stable). It is measured using a vertical line from the centre of the head of the femur and with another line to the lateral rim of the acetabulum
3 supporting ligaments around the hip joint?
ischiofemoral, pubofemoral, iliofemoral
when are hip ligaments taut? what is this also referred to as?
hip extension, “closed pack” (opposite = “open pack ie laxed)
Where do the hip joint ligaments attach distally?
intertrochanteric line
What part of the connective tissue around the hip joint is the thickest/strongest
superior band of the iliofemoral ligament
What is piriformis syndrome
when the piriformis muscle irritates the sciatic nerve. The nerve often forms through the muscle belly etc. 15% of the population have this issue.
What is the blood supply to the head of the femur and what happens when this is damaged?
retinacular arteries (branch of obturator artery), necrosis of the head of the femur and subsequent collapse
