Foot drop is also known and "drop foot." This is where the patient cannot lift their forefoot secondary to weakness of the dorsiflexor muscles. Foot drop can be caused by muscular, skeletal, or nervous system disorders.
Anatomy
Compartment | Muscles | Action | Nerve Supply | Blood Supply |
---|---|---|---|---|
Anterior | Sartorius and quadriceps muscles (rectus femoris, vastus lateralis, vastus intermedius, vastus medialis) | Hip flexion | Femoral nerve | Superficial femoral artery |
Medial | Pectineus, obturator externus, gracilis, and adductor muscles (longus, brevis, magnus, minimus) | Hip adduction | Obturator nerve | |
Posterior | Biceps femoris, semimembranous, and semitendinous muscles | Hip extension | Sciatic nerve | Deep femoral artery |
Compartment | Muscles | Action | Nerve Supply | Blood Supply |
---|---|---|---|---|
Anterior | Tibialis anterior, extensor hallucis longus, extensor digitorum longus, and peroneus tertius | Dorsiflexion and inversion/eversion of the ankle and extension of the toes | Anterior tibial artery | Deep peroneal nerve |
Lateral | Peroneus longus and peroneus brevis | Eversion of the foot and ankle, and weak plantarflexion of the foot | Peroneal artery | Superficial peroneal nerve |
Superficial posterior | gastrocnemius, the soleus, +/- plantaris | Plantarflexion and inversion of the foot at the ankle, and toe flexion | Posterior tibial and peroneal arteries | Tibial nerve |
Deep posterior | Tibialis posterior, flexor hallucis longus, flexor digitorum longus, and popliteus muscles. | Plantarflexion and inversion of the foot at the ankle, and toe flexion | Posterior tibial and peroneal arteries | Tibial nerve |
