Foot drop, sometimes called drop foot, is a general term for difficulty lifting the front part of the foot. If you have foot drop, the front of your foot might drag on the ground when you walk. Foot drop isn't a disease. Rather, foot drop is a sign of an underlying neurological, muscular or anatomical problem.

A tendon transfer is a surgery that moves a working muscle and tendon to replace a non-working muscle and tendon. For example, after a broken wrist, the tendon to the thumb (EPL tendon) that allows you to make a “thumbs-up” can break. Often, the two ends of the tendon are very damaged and cannot be sewn back together.

Extensive research now shows that it is possible for vein damage to heal. Issues such as a vein blockage or damaged venous valves can be repaired and reversed. Whether it's through controlled diet, medication, surgery, or a combination of the three, it is possible to recover at least some of the damage.

A skin graft is where healthy skin is removed from an unaffected area of the body and used to cover lost or damaged skin. They can be used for bone fractures that break the skin (open fractures), large wounds, or where an area of the skin is surgically removed – for example, due to cancer or burns.

Flap surgery is a technique in plastic and reconstructive surgery where any type of tissue is lifted from a donor site and moved to a recipient site with an intact blood supply. This is distinct from a graft, which does not have an intact blood supply and therefore relies on growth of new blood vessels.

Surgery. A large bedsore that fails to heal might require surgery. One method of surgical repair is to use a pad of your muscle, skin or other tissue to cover the wound and cushion the affected bone (flap surgery).
