LE Mononeuropathy Flashcards
Injury to which nerve can result in trendelenburg gait
Superior gluteal nerve - weakness of hip abduction and ER
Largest and longest branch of femoral nerve
Saphenous nerve
2 divisions of sciatic nerve and which is medial and lateral
Tibial (medial) and peroneal (lateral) nerve
What gait abnormality can be seen with obturator neuropathy
Circumducting gait
Nerve root of superior and inferior gluteal nerves
Superior - L4, L5, S1
Inferior - L5, S1, S2
What muscle is commonly affected in deep peroneal neuropathy
EDB
In common peroneal neuropathy, what muscle innervated by peroneal nerve is spared?
