CAM walker boot liners play an important role in making the walkers comfortable and stable. CAM walker liners are usually made of foam in order to give added comfort to the boots.
CAM walkers are used by patients who suffer injury to the lower foot or ankle. It is normally recommended in the case of ankle sprains, soft tissue injuries, ligament tear, tendonitis and fractures. In short, the CAM walker is a good device to use when your feet need to be immobilized. They are also recommended as they help to control movement during the rehabilitation process.
CAM walker boot liners and their role:
The basic design of the CAM walker can be divided into three parts – the sole or foot rest (which is normally made of plastic), the CAM walker boot liner and the Velcro strapping. There are aluminium struts on the side and a joint mechanism which helps to keep the ankle in place.
To use the device, put your feet into the CAM walker liner before place it flat against the foot rest or sole. The heel must be flat against the sole. The liner is then wrapped securely around the leg. It is fixed in place using the Velcro straps. By the time your leg is strapped into place, the liner will have adjusted itself to the contours of your leg to give you a snug and comfortable fit. The liner provides stability, protection and ensures that your damaged extremity is immobilized.
Maintaining the CAM Walker boot liners
Maintaining your CAM walker is very important. Continuous use of the boot over a few days can cause it to give off a peculiar odor. The odor can be minimised by wearing an athletic sock before wrapping your feet around the boot liner. In addition, the liner should be washed every four to seven days. Most liners come with care instructions. Following them carefully can help to prolong the life of the liner. It is normally recommended that the liner should be hand washed using cold water and a mild soap. It should be air dried completely before re-use.
Even if you do follow the care instructions precisely, it is unlikely that your CAM walker liners will last for more than six weeks. Replace the liners the minute you notice any wear and tear.
Types of CAM Walker boot liners
The different types of boot liners available in the market are as follows:
(i) Air-inflated liners or pneumatic liners: The liners have pre-inflated pneumatic cells which make them more stable and comfortable. The pneumatic liners also ensure that you are able to walk with a natural gait.
(ii) Standard liners: The standard liners are the foam liners. They do not have the inflatable cells but do provide basic support and stability. The standard liners are normally used for patients with minor injuries.
Precautions to be taken while using CAM Walker boot liners
- Proper fitting of the liner is necessary for proper rehabilitation. Make sure that the Velcro fasteners are not pulled too tight as this can constrict the circulation of blood and thus delay healing.
- Check your skin from time to time to ensure that there is no redness due to contact with the liners. In case there is persistent redness, do contact your physician.
- Investing in breathable foam liners is a wise idea as it gives higher levels of comfort. This is especially true if you live in a region which has high temperatures. The hot climate can make the foam liner feel uncomfortable against your skin. The breathable foam liners will be cooler.
The quality of the CAM walker liners will determine the stability and the support that the boots can provide to your injuries. It is thus essential to buy the right kind of CAM walker liners.
