Abstract EN
This review outlines the anatomy of the obturator nerve and the indications for obturator nerve block (ONB).
Ultrasound-guided ONB techniques and unresolved issues regarding these procedures are also discussed.
An ONB is performed to prevent thigh adductor jerk during transurethral resection of bladder tumor, provide analgesia for knee surgery, treat hip pain, and improve persistent hip adductor spasticity.
Various ultrasound-guided ONB techniques can be used and can be classified according to whether the approach is distal or proximal.
In the distal approach, a transducer is placed at the inguinal crease; the anterior and posterior branches of the nerve are then blocked by two injections of local anesthetic directed toward the interfascial planes where each branch lies.
The proximal approach comprises a single injection of local anesthetic into the interfascial plane between the pectineus and obturator externus muscles.
Several proximal approaches involving different patient and transducer positions are reported.
The proximal approach may be superior for reducing the dose of local anesthetic and providing successful blockade of the obturator nerve, including the hip articular branch, when compared with the distal approach.
This hypothesis and any differences between the proximal ONB techniques need to be explored in future studies.
