Medial Side Of Thigh Flashcards
Medial compartment of thigh is also known as
Adductor compartment
Chief nerve of adductor compartment
Obturator nerve
From where does obturator nerve arise and it’s root value
It arises from ventral division of anterior primary rami L2 L3 and L4 spinal nerves of lumbar plexus.
How does obturator nerve enter thigh
By passing through obturator canal
Course of obturator nerve
It passes through the obturator canal and there it divide to anterior and posterior division.
Anterior division:
* It passes in front of obturator externus
*then passes behind pectineus and adductor longus
* Again pass infront of adductor breves.
Posterior division:
* It pierces obturator externus.
*passes behind adductor breves
*passes infront of adductor Magnus.
Muscles supplied by anterior obturator nerve
Adductor breves
Adductor longus
Pectineus
Gracilis
Articular twig to hip joint
Twig to subsartorial plexus of nerves
Terminates by supplying femoral artery in adductor canal.
Muscles supplied by posterior obturator nerve
Obturator externus
Adductor brevis
Adductor magnus
Terminal branch of posterior obturator nerve
Terminal branch is known as genicular branch.
Pierces adductor Magnus or passes through adductor hiatus to reach popliteal fossa.
Passes along with popliteal vessels and pierces oblique popliteal ligament and supplies knee joint.
Adductor spasm of thigh
Spastic paraplegia:
*spasm of adductors in thigh
* severe pain in the inner aspect of thigh
* relieved by surgical division of obturator nerve.
Referred pain
In diseases of knee joint, pain may be felt in hip joint along the obturator nerve because both are supplied by it.
Gracilis graft
Because of its long length, location of nutrient vessels and nerve in terminal part it is used to graft in damaged external anal sphincter due to pelvic trauma and face paralysis.
