Hip: Anatomy 4 Flashcards
normal hip ROM: flex
120-135˚
normal hip ROM: extension
10-30˚
normal hip ROM: abduction
30-50˚
normal hip ROM: adduction
10-30˚
normal hip ROM: IR
30-45˚
normal hip ROM: ER
45-60˚
dynamic loads across hip joint: normal walking (%) BW
238%
dynamic loads across hip joint: climbing stairs (% BW)
251%
dynamic loads across hip joint: descending stairs (% BW)
260%
Cyriax hip: capsular pattern
flex > abd > IR
Cyriax hip: with capsular pattern, sometimes this motion is most limited
IR
Cyriax hip: closed packed position
ext
IR
abd
close packed position of the hip also used for positioning for this SIJ technique
prone LAD HVLAT
Cyriax hip: open packed position
30 flex
30 abd
20 ER
Open packed position of the hip is used for this manual therapy technique
positioning for LAD of the hip
lateral femoral cutaneous nerve entrapment aka
paresthetica meralgia
lateral femoral cutaneous nerve: originates from
L2-3
lateral femoral cutaneous nerve: paresthetica meralgia
symptoms
- pain
- numbness
- paresthesia over anterior/lateral thigh
lateral femoral cutaneous nerve: paresthetica meralgia
symptoms worsened with what aggs?
- prolonged standing
- hip ext/adduction
lateral femoral cutaneous nerve: paresthetica meralgia
motor/reflex signs?
no
lateral femoral cutaneous nerve: paresthetica meralgia
who often gets this?
- workers who wear a toolbelt
- large abdomen wearing tight restrictive belts
lateral femoral cutaneous nerve: paresthetica meralgia
need to differentiate between
L2-3 radiculopathy
femoral neuropathy
lateral femoral cutaneous nerve: where does the nerve run?
- through pelvis anteriorly
- angles down at ASIS and passes through inguinal ligament
- moves toward lateral thigh and pierces fascia latae
obturator nerve: originates from
L2-4
obturator nerve: formed within what structure?
psoas
obturator nerve: formed within the psoas, it runs where?
through pelvis to the obturator canal
obturator canal: made up of what?
- fibrous membrane from obturator muscles
- obturator groove in pubic bone
obturator nerve: where commonly trapped?
obturator canal
obturator nerve entrapment: causes
- trauma from pelvic fx
- inflammation from pubic bone/hip surgery
obturator nerve entrapment: symptoms
pain location
- groin
- medial thigh/knee
obturator nerve entrapment: symptoms
pain with palpation of
inguinal ligament
obturator nerve entrapment: symptoms
pain at end range (motions)
- flexion
- extension
- abduction
obturator nerve entrapment: symptoms
weakness in what muscle group
adductors
obturator nerve entrapment: symptoms
weakness in adductors may lead to (gait)
- circumduction during swing
- Duchenne during stance
obturator nerve entrapment: differentiate from these potential pathologies
- L2-4 radiculopathy
- femoral neuropathy
- hip arthritis
- psoas strain
obturator nerve entrapment:
differentiating from L2-4 radiculopathy
- L2-3 have similar distribution to obturator nerve, but not as much L4
- pressure over groin doesn’t cause pain in lumbar radiculopathy***
