Obturator nerve entrapment

Obturator neuropathy is a rare condition occurring secondary to compression of the anterior branch of the obturator nerve at several different sites of entrapment. The condition most commonly manifests with deficits in medial thigh sensation and adductor musculature strength. Symptoms are often vague due to dual innervation of structures involved in the condition’s pathoanatomy. Diagnosis is often complicated by the many adjacent structures that are prone to other forms of injury. Advanced imaging including MRI and EMG can facilitate accurate identification of obturator pathology. Potential treatments including injection and therapy have been described; however, surgical release is advocated as the consensus method of definitive intervention, especially in the setting of confirmed chronic nerve entrapment.
