Here's some more detail on these causes:
Nerve injury. Most commonly, foot drop is caused by an injury to the peroneal nerve. The peroneal nerve is a branch of the sciatic nerve that wraps from the back of the knee to the front of the shin. Because it sits very close to the surface, it may be damaged easily.
An injury to the peroneal nerve may also be associated with pain or numbness along the shin or the top of the foot.
Some common ways the peroneal nerve is damaged or compressed include:
Sports injuries
Diabetes
Hip or knee replacement surgery
Spending long hours sitting cross-legged or squatting
Childbirth
Time spent in a leg cast
Injury to the nerve roots in the spinemay also cause foot drop.
Brain or spinal disorders. Neurological conditions can contribute to foot drop. These include:
Stroke
Multiple sclerosis (ms)
