Week 2 Flashcards
(24 cards)
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
trochanteric bursitis =
inflammation of hip bursae
what is the angle of inclination of the femur?
the angle between the long axis of the femur and the neck of the femur. It is smaller in women.
Normal angle of inclination of the femur name?
increased?
decreased?
Coxa norma
coxa valga
coxa vara
what does coxa valga cause
reduces lever arm, more force transmitted through hip abductors. Greater force through lateral acetabulum.
What does coxa vara cause
increased stress over medial head of femur
How is the angle of torsion measured?
angles between the condyles of the femur and axis of femoral neck. Normal = 12-15 degrees. decreases w age
what is a decreased angle of torsion referred to as?
retroversion
What is an increased angle of torsion referred to as?
anteversion
What is lumbopelvic rhythm?
movement starts from HAT, pelvis shifts backwards to keep COM normal, first 45 degrees flexion leaves the spinal extensors maintaining balance, pelvis then rotates forward, gules and hamstrings coordinate this part of movement until at full range.
