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 …

Background and Objectives The femoral and obturator nerves are assumed to account for
the primary nociceptive innervation of the hip joint capsule. The fascia iliaca compartment …

Arthroscopic anterior cruciate ligament (ACL) reconstruction with hamstring grafting is a
common orthopedic procedure that is associated with moderate-to-severe pain. Peripheral …

A Prospective Study to Compare Analgesia from Femoral Obturator Nerve Block with Fascia
Iliaca Compartment Block for Acute Preoperative Pain in Elderly Patients with Hip Fracture …

Purpose The obturator nerve branches into the obturator canal; therefore, local anesthetic
spread into the obturator canal predicts the success of the obturator nerve block (ONB). We …

Pelvic entrapment neuropathies represent a group of chronic pain syndromes that
significantly impede the quality of life. Peripheral nerve entrapment occurs at specific …

The obturator nerve variably gives off the anterior, posterior, and hip articular branches
along its course; however, all branches invariably pass through the obturator canal. Herein …

Purpose of review: Novel motor-sparing peripheral nerve blocks in hip and knee procedures
are desirable. Recent findings The application of ultrasound (US) in fascial plane blocks has …

Background Different approaches to the obturator nerve have been described. However, few
have focused on the injection point inferior the iliopubic ramus, specifically at the exit of the …

Introduction A proximal obturator nerve block has a similar block efficacy as the distal
obturator nerve block. Previous cadaveric investigation injecting methylene blue dye …
