All branches of the obturator nerve (ON) can be anesthetized in the thigh. The ON can be blocked by either a subpectineal approach or selective approaches to each of the anterior and posterior branches (Fig. 58.1 ). The ON can also be anesthetized as part of a lumbar plexus block, also known as a psoas compartment block. An obturator nerve block is an injection of a steroid, an anesthetic or a combination of both, near the obturator nerve, which is primarily a motor nerve arising from the third and fourth lumbar nerves, with distribution to the hip and thigh; this type injection is most commonly used as part of regional anesthesia for kneesurgery. For the treatment of headache disorders, the greater occipital Fourteen obturator nerve blocks, in 8 patients, were carried out by blind anatomical approach, as controlled by image-intensifier fluoroscopy and electrical stimulation. After description of techniques and analysis of results, it is concluded that the anatomical approach, as controlled by electrical stimulation of the nerve, is the most accurate method. 0.5 mA was found to be the pertinent Obturator nerve blocks should be avoided in the presence of a coagulopathy. Anatomy The obturator nerve is a mixed nerve, which, in most cases, provides motor function to the adductor muscles and cutaneous sensation to a small area behind the knee. It is derived from the anterior primary rami of L2, L3 and L4 ( Figure 34-1 ). In blocks in which multiple lower extremity nerves are targeted (e.g., the posterior lumbar plexus block or the anterior 3-in-1 block), the obturator nerve has a relatively low block success rate. Therefore, the obturator nerve block is an important adjunct for lower extremity analgesia. Other indications for obturator nerve block include relief of hip pain, treatment of adductor spasticity [4] In the literature, there is only one report on ultrasoundguided obturator nerve block (USONB) for transurethral resection surgery (TUR) procedures where Fujiwara described 23 blocks for Obturator nerve block is useful in the evaluation and management of hip pain and spasm of the hip adductors thought to be mediated by the obturator nerve. The technique also is useful to provide surgical anesthesia for the lower extremity when combined with lateral femoral cutaneous, femoral, and sciatic nerve block.
