Flashcards in hip Deck (36):
main hip flexor
main hip extensor
main hip abductor
main hip adductor
main hip internal rotator
tensor fascia lata
main hip external rotator
what is a significan LLD?
Proximal weakness is evidenced by a _________gait where the patient is relying on ________muscles, rather than flexor/extensors
This test puts patient in extended butterfly and tests the _______ joint
This test is the same as the obturator test
FADIR (flexion adduction, internal rotation)
This problem is more common in males in 30's-50's who present c/o a dull ache/throbbing pain around hip (groin, lateral, or buttocks). It is most common in people with h/o EtOH, steroid use, SCC, or chemo
osteonecrosis of the femoral head (AVN)
Osteonecrosis AVN occurs over 5 stages on xray. What are they?
0) No change on xray
1) mottled densities
2) crescent sign, increased densities in femoral head
3) flattening of femoral head, normal joint space
4) narrowing joint space, acetabular changes
5) advanced degenerative changes
How can you treat ON/AVN of femoral head?
1) before collapse: core decompression
2) after collapse: hemi-arthroplasty or total hip
How many patients go on to have ON/AVN of the other hip?
This problem is caused by friction from overuse, trauma, or a direct blow.
This bursitis is worst when seated
This bursitis is due to microtrauma and s/s include anterior hip pain. Relief with hip flexion and external rotation
this bursitis is a/w LLD, broad pelvis, poor running, and tight IT band. Worse with external rotation. Positive Ober test
Another term for sciatica is?
nerve pain over the lateral thigh, most often in obese patients is likely affecting the ________nerve
lateral femoral cutaneous
If missed, _________ and __________ are a/w a 50% mortality rate in the setting of pelvic fx
vaginal laceration or perforated colon
What type of hip fx occurs just under the ball of the hip joint?
subcapital neck fx
what type of hip fx occurs mid neck?
transcervical neck fx
what type of hip fx occurs between the base of the neck of the femur and the base of the trochanters?
what type of hip fx occurs below the trochanters
What type of hip fx avulses the upper/lower trochanter
Greater/lesser trochanteric fx
What is included in "intracapsular" fractures?
femoral neck and capitulum
what is the likely MOI for intracapsular fx?
indirect shear force on angulated femoral neck.
PE for intra-capsular
shortened leg, external rotation, painful ROM
PE for extra-capsular
MORE external rotation, significant blood loss, no wt bearing
Most common type of hip dislocation
What is the MOI for posterior hip dislocation?
femoral head forced backward, tearing ligamentum teres and posterior capsule, fx of acetabulum
What are you worried about with posterior hip dislocation?
AVN, emergency reduction
What does leg with posterior hip dislocation look like?
internal rotation, hip flexed and adducted
what is the MOI for an anterior dislocation?
forceful abduction and external rotation
