What are the signs and symptoms of obturator nerve entrapment?

One possible cause of pain is due to fascial entrapment of the nerve. Symptoms include medial thigh or groin pain, weakness with leg adduction, and sensory loss in the medial thigh of the affected side. Radiographic imaging provides limited diagnostic help.

What does the obturator nerve affect?

The obturator nerve (L2–L4) supplies the pectineus; adductor (longus, brevis, and magnus); gracilis; and external obturator muscles. This nerve controls adduction and rotation of the thigh.

How is obturator neuropathy treated?

For anterior obturator nerve entrapment, treatment may consist of electrical stimulation of the adductor and hip flexor muscles, stretching, and massage. These modalities, however, typically have not been successful in resolving this condition if it is not recognized early.

How do you know if you have an obturator nerve?

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 1). On its initial course, it runs within the psoas major muscle.

What does obturator pain feel like?

The patient may describe a deep ache in the region of the adductor origin at the pubic bone that increases with exercise; the pain may radiate down the medial aspect of the thigh toward the knee. An athlete’s ability to jump may be reduced. The weakness in these patients usually worsens with exercise.

What is obturator jerk?

Electrical stimulation of the nearby obturator nerve during electroresection of lateral wall tumors can result in a powerful adductor spasm of the leg known as an “obturator jerk”. An obturator jerk during TURBT greatly increases the risk of bladder perforation.

What causes obturator Externus pain?

The obturator internus can become tensioned or spasmed from overworking, muscle imbalances, injuries, and postural changes.

How do you treat an obturator internus pain?

The obturator internus tendon sheath and bursa were injected with 2.5 ml of 0.5% lidocaine combined with 10 mg of triamcinolone. The patient reported immediate complete relief of pain with continued relief at 2 and 6 months post-injection.

How do I heal my obturator Externus?

Pain normally disappears with rest of the joint for a couple days or weeks. Treatment of inflammation and discomfort includes the use of ice and NSAIDs, like ibuprofen. The use of corticosteroids is another form of treatment that may provide pain relief for a case of bursitis that does not clear up quickly.

  • Can the obturator nerve cause groin pain?

    Likewise, nerve entrapment , such as obturator nerve or ilioinguinal nerve entrapment, may cause burning or lancinating groin and middle thigh pain , as well as other neurological symptoms like numbness and tingling.

    Where does the obturator nerve distribute to?

    The obturator nerve is located just medial (midline) to the psoas and travels with this large muscle until it reaches the obturator foramen. Once the nerve is the obturator foramen it exits the pelvis and travels deep within the adductor muscles in a fascial sheet until it reaches and the back of the knee.
