Disease relevance of Obturator Nerve

• To clarify the true nature and the mechanism of the human adductor brevis (specific adductor brevis, SAB) innervated dually by the anterior and posterior branches of the obturator nerve, we have carried out gross anatomical examination of 100 body halves of 50 adult Japanese cadavers [1].

High impact information on Obturator Nerve

• Acetylcholinesterase (AChE; EC 3.1.1.7) isoenzymes in gracilis muscles from adult Sprague-Dawley rats were studied 24-96 h after obturator nerve transection [2].
• The sciatic, femoral, and obturator nerves were infiltrated with 1% lidocaine and 0.25% bupivacaine [3].
• A selective obturator nerve block with 7 mL of 0.75% ropivacaine was performed in 30 patients scheduled for knee surgery [4].
• Twenty-four consenting patients undergoing transurethral surgery during spinal anesthesia were randomized to receive direct obturator nerve block with 10 mL of plain bupivacaine 0.5% (n = 12) or 10 mL of plain etidocaine 1% (n = 12) [5].
• Patients were randomly assigned to receive 3-in-1 block with 40 mL (n = 13) or 50 mL (n = 11) of 1.5% lidocaine plus epinephrine, or direct obturator nerve block with 10 mL of 2% lidocaine plus epinephrine (n = 20) [6].

Anatomical context of Obturator Nerve

• METHODS: Sixty patients were randomised into one of two groups: combined femoral and sciatic nerve block with 15 ml 0.75% ropivacaine to each nerve or combined femoral and sciatic nerve block with 15 ml 0.75% ropivacaine to each nerve and an obturator nerve block with 5 ml 0.75% ropivacaine [7].

Associations of Obturator Nerve with chemical compounds

• This was successfully diagnosed and treated by obturator nerve blocks with anesthetic and steroid at the obturator foramen [8].
• In spite of prior blockade of the obturator nerve with 1% mepivacaine (8 ml) utilizing a nerve stimulator, violent leg jerking was evoked during transurethral electroresection of a bladder tumour approximately 1 h after the blockade in a 68-year-old man [9].
• Rat obturator nerve 16S acetylcholinesterase (16S AChE) was separated by sucrose gradient velocity sedimentation and compared to the 16S form of AChE similarly derived from endplate regions of anterior gracilis muscles [10].

Gene context of Obturator Nerve

• In the close examination of the intramuscular distribution of the nerve to the SAB, the region innervated by the anterior branch of the obturator nerve could clearly be distinguished from that innervated by the posterior branch [1].
• The obturator nerve had a mean distance of 3 cm lateral to the midline [11].

Analytical, diagnostic and therapeutic context of Obturator Nerve

• The effects of rat obturator nerve extracts on total and 16S acetylcholinesterase (AChE) activity were studied in endplate regions of denervated anterior gracilis muscles maintained in organ culture for 48 hr [12].
