Foot Drop

What Is Foot Drop?

Foot drop is a term used to describe the inability to extend or dorsiflex the foot. This type of weakness usually results in the inability to walk without tripping because the toe of the foot is not able to clear the floor after taking a step. Meaning, the front part of your foot may drag on the ground while you walk. Foot extension weakness is directly due to weakness of the tibialis anterior muscle that is responsible for this motor function. This is not a disease, but is instead a symptom of an underlying neurological condition. Depending on the case, a foot drop could be temporary or permanent. An individual might need to use a brace on the ankle or foot to walk normally.

Foot Drop Causes

Causes of foot drop are due to conditions that affect innervation of the tibialis anterior muscle. Common causes include L4/L5 radiculopathy or peroneal nerve palsy. L4/L5 radiculopathy occurs in the lower lumbar spine and is usually due to a herniated disc that impinges upon the exiting L4 or L5 nerve root. Peroneal nerve palsy on the other hand, is due to distal peripheral nerve injury in the leg just above the ankle. Often, this occurs due to compression of the peroneal nerve by a tendon or a tumor or due to trauma.

To differentiate between radiculopathy versus peroneal nerve palsy your physician should check for foot inversion and gluteus medius weakness (internal rotation of flexed hip)–both are spared and peroneal nerve palsy and both should be involved with radiculopathy.  Other causes of foot drop include lumbar plexus injury, peripheral neuropathy, parasagittal brain lesions, spinal cord injury, muscular dystrophy, or ALS.

Treatment And Surgery For Foot Drop

WARNING: If patients or healthcare providers suspect a foot drop, urgent neurosurgical evaluation is warranted!

Treatment for foot drop caused by a herniated lumbar disc usually involves surgical microdiscectomy.  In mild cases, nonsurgical management may be initially pursued.  This may include pain medication and physical therapy.  However, in cases of acute or abrupt foot drop patients should be immediately evaluated by a neurosurgeon.  Sudden and significant motor weakness may require urgent surgical intervention in an effort to prevent permanent disability.  Treatment for foot drop caused by peroneal nerve injury or peroneal nerve palsy may involve surgery that effectively decompresses the nerve from the offending tendon or tumor.  All cases of foot drop should be thoroughly investigated so that the specific cause can be identified and appropriately treated.

"The Doctor outstanding in every way possible. Explaining every detail and taking his time to do so. Amazing for a surgeon to be so informing of the procedure to me and my wife. After the surgery he came out and explained everything to me. My wife is doing great after the cervical spine fusion, moving her arm in ways she hasn’t in years and getting her feeling back in her fingers"
