There are many causes of acute onset foot drop ranging from deep fibular nerve or sciatic nerve injury caused by trauma or a compressive mass such as a neuroma, to spinal cord disorders like disc herniation causing L4-5 radiculopathy, and various muscular dystrophies affecting the tibialis anterior muscle responsible for foot dorsiflexion and eversion. Even brain disorders like MS, stroke or ALS can result in foot drop. We present a case of bilateral foot drop as a complication of rapid 70 lb weight loss which was described in literature previously as “slimmer’s palsy”.
