Lower Limb Entrapments Flashcards
What nerves are in the lumbar plexus
- Iliohypogastric L1
- Ilioinguinal L1
- Genitofemoral L1-L2
- Lateral femoral cutaneous L2-L3
- Obturator L2-L4
- Femoral L2-L4
“Interested in getting laid on Friday’s”
What nerve cord segments are in the sacral plexus
S2,3,4 “keeps the 3 P’s off the floor - penis poo pee”
Penis autonomic innervation actions
Parasympathetic - points
Sympathetic - shoot
What 5 muscles are most commonly detected (98%) of lumbar radiculopathies
- Tibialis anterior
- Extensor hal longus
- Gastrocnemius
- TFL
- Adductor longus
External or internal compression of the lateral femoral cutaneous nerve against the inguinal ligament
Meralgia paresthetica
This nerve innervates the adductor breviary, adductor longus, gracilis, & adductor magnus
Obturator nerve
Comprised of 4-5 lumbar plexus roots & 1,2,3 sacral plexus roots
Sciatic nerve
Innervates the semitendinosus, biceps femoris long & short head, semimembranosis, & adductor Magnus
Sciatic nerve
This nerve divides into peroneal & tibial nerves proximal to the popliteal fossa
Sciatic nerve
What muscles does the tibial nerve innervate
Gastroc medial & lateral head, popliteus, soleus, tibialis posterior, flexor digitorum longus, flexor hallucis longus
Where is the tibial nerve most commonly trapped
Tarsal tunnel
Nerve comprised of lumbar plexus roots 4-5 & sacral plexus roots 1-2
Peroneal nerve
Nerve that innervates the tibialis anterior, ext digitorum longus, ext hallucis longus, peroneus tertius, ext digitorum brevis; peroneus longus, & peroneus brevis
Common peroneal nerve
Where is the common peroneal nerve mostly lesioned
Area around knee & fibular head
Charcot-Marie-tooth / peroneal muscular atrophy is also known as
Hereditary motor sensory neuropathy
