Mechanism of action
This is a regional anesthesia technique in which local anesthetic is injected near the obturator nerve, which innervates the adductor muscles of the thigh and provides sensory coverage to the medial knee. The block interrupts nerve conduction, producing anesthesia and analgesia in the distribution of the obturator nerve. It is commonly used as an adjunct to other regional blocks or general anesthesia during orthopedic and urological procedures.
