Hip: Anatomy 5 Flashcards
Femoral nerve: originates from
L2-4
Where does femoral nerve entrapment typically occur?
- femoral triangle
- inguinal ligament
Femoral nerve runs between these two muscles toward the thigh
between psoas and iliacus
The femoral nerve descends between the psoas and iliacus, passes over the (structure) and under the (ligament) to the thigh
over the superior pubic ramus
under the inguinal ligament
Causes for femoral nerve entrapment
- pelvic fx
- forceps injury during labor
- scarring
- tumors
- inguinal hernia
femoral nerve entrapment: symptoms
pain and paresthesia where?
anteromedial thigh
medial knee
femoral nerve entrapment: symptoms
pain worst where? knee or thigh?
knee
femoral nerve entrapment: symptoms
pain at end range with what motions?
hip flexion
hip extension
femoral nerve entrapment: symptoms
which muscles are commonly weak?
quadriceps
sartorius
femoral nerve entrapment: symptoms
reflexes?
diminished patellar reflexes
femoral nerve entrapment: symptoms
gait
(+) gait abnormalities
femoral nerve entrapment: symptoms
neural tension?
yes
femoral nerve entrapment: need to differentiate between these other diagnoses
- L2-4 radiculopathy
- psoas strain
- hip arthritis
femoral nerve entrapment: very similar to this level of radiculopathy
L4
femoral nerve entrapment:
how to differentiate from L4 radiculopathy
check strength of…
paraspinals
adductors
tibialis anterior
sciatic nerve: originates from
L4-S3
sciatic nerve: where does entrapment typically occur?
- bony sciatic notch
- possibly myofascia of piriformis
sciatic nerve: causes for entrapment
- external trauma
- scarring
- misplaced intramuscular injection to nerve
- gluteal/pelvic tumors
sciatic nerve: symptoms
tenderness where?
sciatic notch
sciatic nerve: symptoms
radiation of pain/paresthesia where?
posterior leg and foot
sciatic nerve: symptoms
partial loss of sensation where?
posterior thigh
distal buttock
sciatic nerve: symptoms
weakness where
muscles innervated by sciatic nerve
sciatic nerve: symptoms
reflexes?
diminished Achilles reflex
sciatic nerve: symptoms
neural tension?
yes
sciatic nerve: differentiate from lumbar radiculopathy
what are the key nerves to test?
gluteal nerves are key
sciatic nerve: differentiate from lumbar radiculopathy
palpation/neural tension?
palpation of nerve and neural tensioning are NOT helpful
sciatic nerve: differentiate from lumbar radiculopathy
disc herniation
difficult to differentiate sciatic nerve from lumbar disc herniation
