Obturartor Neuropathy: A Cause of Exercise-Related Groin Pain, Which particularly in athletics who do much running, twisting, turning, and kicking. Pain usually begins at the adductor orgin on the pubic bone and worsens with excerise. Diagnostic measures include reporduction of pain by stretching the pectineus muscle after exercise, electromography, and local anesthetic block of the obturator nerve. Surgery allows the athlete to resume pervious levels of activity. The obturator nerves aries from the posterior divition of nerve roots L2 to L4 and runs over the pelvix rim into the lessor pelvis. The mechanisms of oburator nerve entrapment is unclear. But, the entrapment does not appear to occur within the fibrosseous obturator tunnel but rather at the level of the obturator foraman and proximal thigh where the fascia stops the anterior branch of the nerve as it passes over the adductor brevis muscle. Mainly all athlets who have Obturartor Neuropathy are males that participate in Australian football or soccer. All presented with groin pain of more than 3 months' of duration. Pervious treatment includes physical therapy, consisting of muscle stimulation, strengthening, stretching, and message therapy.
Signs and symptoms: Athletes who have Obturartor Neuropathy typically present with an insidious onset of groin pain, which is described as a deep ache center on the adductor orgin at the pubic bone. During exercisethe pain is more painfull and may radiate down the medial side. More so down by the knee, mainly noticed when attemted to jump. Adductor weakness and muscle spasms are more likely to occur after exercise. In cases of Oburartor Neuropathy lasting longer then 3 months, electromyography (EMG) studies, performed by listing the needle in to the belly of the athletes's adducor muscles, show a pattern of dernervation in the adductor longus and brevis muscles. Surgery is the preferred treatment for patients who have the clinical featues of Obturautor Neuropathy and evidence of denervation on the EMG.
