Obturator Nerve Injury (L2-L4)
Overview
Plain-Language Overview
Obturator Nerve Injury (L2-L4) affects a nerve that controls muscles in the inner thigh and provides sensation to part of the leg. This nerve is important for movements like bringing the legs together, which is called adduction. When this nerve is damaged, people may experience weakness in leg movement and numbness or tingling in the inner thigh. The injury can happen due to trauma, surgery, or pressure on the nerve. This condition mainly impacts the musculoskeletal and nervous systems, affecting walking and leg stability.
Clinical Definition
Obturator Nerve Injury (L2-L4) is a neuropathy involving damage to the obturator nerve, which arises from the lumbar plexus (nerve roots L2-L4). The injury commonly results from pelvic trauma, surgical procedures such as pelvic lymph node dissection, or compression by masses. This nerve innervates the adductor muscles of the thigh and provides sensory input to the medial thigh. Clinically, the injury manifests as weakness of thigh adduction, gait disturbance, and sensory loss over the medial thigh. The condition is significant because it impairs lower limb function and can complicate recovery after pelvic surgeries. Diagnosis requires careful clinical examination and may be supported by electrodiagnostic studies.
