What does the obturator nerve supply?
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. A small cutaneous zone on the internal thigh is supplied by sensory fibers.
What are the symptoms of obturator nerve damage?
Obturator neuropathy is a difficult clinical problem to evaluate. 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.
Is obturator nerve somatic?
The somatic nerves of the pelvis include the Lateral Femoral Cutaneous nerve, Femoral nerve, Genitofemoral nerve, Obturator nerve and the Lumbosacral trunk.
What are the signs and symptoms of obturator nerve entrapment?
What are the symptoms of obturator nerve entrapment?
- reduced range of movement.
- swelling/inflamation.
- stiffness.
- weakness.
- numbness.
- spasm.
What is the clinical significance of the obturator nerve?
The obturator nerve is responsible for the sensory innervation of the skin of the medial aspect of the thigh. The nerve is also responsible for the motor innervation of the adductor muscles of the lower limb (external obturator.
Where do you feel obturator nerve pain?
What are the symptoms of obturator nerve entrapment? Pain is initially felt in the groin, usually during exercise. If you continue to exercise, the pain worsens and, usually, radiates down the inner thigh.
How do you treat obturator nerve pain?
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.
Why does my obturator hurt?
The obturator internus can become tensioned or spasmed from overworking, muscle imbalances, injuries, and postural changes. Some symptoms of obturator internus muscle tension include: Hips that feel tight and your feet always seem to be rotated out. Lateral hip pain, can be mistaken for IT band syndrome/bursitis.
What is the function of the obturator nerve?
The obturator nerve is a major peripheral nerve in your thigh. It’s responsible for some leg movements (motor function) as well as sensation (sensory function). This nerve is formed by portions of the lumbar plexus , which is a complex network of nerves that emerge from the lumbar region of the spine, which is in your lower back.
Where does the obturator nerve pierce the thigh?
Pierces the obturator externus muscle, and then descends in a plane between the adductor brevis and adductor magnus. Innervates the obturator externus and adductor magnus muscles. The obturator nerve innervates all the muscles in the medial compartment of the thigh – except the hamstring part of the adductor magnus (innervated by the tibial nerve).
Is the obturator nerve distal to the knee?
However, the obturator nerve very rarely provides sensation distal to the knee [5, 7]. Despite the fact that many muscles used in thigh adduction are intervated by nerves other than the obturator n. adduction on the affected side is usually weak.
Is the obturator part of the adductor magnus?
Part of the adductor magnus (its hamstring portion is innervated by the sciatic nerve) The obturator externus is the only non-adductor muscle innervated by the obturator nerve. This muscle is responsible for rotating the thigh outward.
