How Does a Cam Walker Work?

Stabilization

The cam walker lower extremity orthosis has, as one of its primary functions, the ability to stabilize the lower leg and ankle joint and to restrict, if not eliminate, movement in this area. It is typically used as an adjunct in the treatment of severe ligament sprains and fractures, as well as post-surgical bracing. It can also be used to treat tendonitis, diabetic ulcers and other assorted problems of the feet and toes.

Protection

The cam walker orthosis is shaped to promote protection as well as stabilization. The padded lining is comfortable to wear, yet it helps reduce the potential for pressure ulcerations from the side bars and straps during periods of swelling. When sized correctly, the boot portion also provides protection to the toes by extending just beyond the tips, reducing the possibility of accidental stubbing of the toes against furniture or other objects.

Guarded motion

One variation of the cam walker uses adjustable, or "pin"-type, hinges on either side of the brace located over each ankle "knob" (malleolus). These hinges can be set to a predetermined range of motion so that, as the healing phase progresses, and more motion is allowed, it can be done in a very deliberate and incremental fashion.

There are several variations as to types of hinges, but the function and end result are the same.

Help in controlling swelling

Some types of cam walkers have air compartments incorporated into the brace and/or lining so that they may be inflated with a small amount of air. These pads are strategically located throughout the brace so that gentle pressure may be applied to areas such as either side of the ankle, the front on the shin (tibia) and the top of the foot.
