🌿 Obturator Nerve Entrapment 🌿
Anatomy:
The obturator nerve arises from L2–L4 spinal nerves.
Passes through the pelvis and exits via the obturator foramen to supply the medial thigh muscles and skin.
Causes of Entrapment:
Pelvic trauma or fractures
Surgery (hip or pelvic procedures)
Tumors or hematomas in the pelvis
Chronic muscle compression
Symptoms:
Pain or numbness in the inner thigh
Weakness in thigh adduction (difficulty bringing legs together)
Gait disturbance due to medial thigh weakness
Diagnosis:
Clinical examination (strength testing, sensory deficits)
Electromyography (EMG)
Imaging (MRI/CT) to detect structural causes
Treatment:
Physical therapy for muscle strengthening and mobility
Address underlying cause (surgery, tumor removal)
Pain management with medications or nerve blocks
