CAM Walkers, otherwise known as Moon Boots, are an integral part of the recovery process for many patients with foot, ankle, or lower leg injuries. They are designed to optimise your recovery, helping you attain optimum and timely results.
CAM stands for Controlled Ankle Movement. It works by both keeping your foot and ankle fixed in place, and offloading (removing) some of the weight off your foot and ankle while you continue to walk. As you don’t continue to put such high amounts of pressure through the foot, it can heal more effectively.
Moon Boots are often used as a substitute to a plaster cast because they are more durable, hygienic and easily removable. They also have ‘rocker’ soles, meaning that they are easier for you to walk in, and most people do not require crutches unless they feel unstable on their feet.
The benefits of a correctly clinically fitted and aligned Moon Boot are:
- Easy to take off and put on for washing your feet, changing any dressings (meaning fewer skin problems) and controlling any smell, compared to a plaster cast
- Easy walking to get you back to work and daily living faster
- Less pain due to weight offloading effect
- An optional Air (Pneumatic) CAM Walker to help stabilise fractures and reduce swelling
- Closed-toe and hard-shell options are also available for those returning to work
- Often no need or vastly reduced need for crutches
Why Have I Been Prescribed A Moon Boot?
You have a Moon Boot because you have incurred a significant injury to your foot, ankle or lower leg that requires special care and weight redistribution to help you get the best healing outcomes. It is likely that without the Moon Boot, continuing to walk on the foot may slow down your recovery, continue to cause you pain, or even worsen the injury.
Fractures: If you have a fracture of the foot or ankle, your Moon Boot will restrict foot/ankle movement and reduce the stress applied to the fractured bone during healing. It does this by taking some of the weight off the foot and ankle. Some muscular movement is still encouraged within the leg, which can reduce the length of your rehabilitation.
Ligament & Soft Tissue Injuries: If you have a more severe ligament strain or rupture, the Moon Boot will prevent excessive movement of the injured ligament and help you feel more stable on your feet (injured ligaments often cause a feeling of instability). By keeping the ligament in a controlled position with less strain, it can help achieve superior healing outcomes.
What Problems Can A Moon Boot Help With?
CAM Walkers can help with many bone, ligament, and soft tissue (muscular) injuries. If it is a suitable option for you, your Podiatrist will discuss it in your appointment. We often prescribe Moon Boots for:
- Plantar fascia tears
- Achilles tendon tears
- Bone fractures and breaks
- Severe ankle sprains
- Post-surgical offloading (weight redistribution)
- Tendon ruptures and tendonitis
Fitting Your Moon Boot
Before starting to use your Moon Boot, you must have it fitted by your Podiatrist to ensure the right size, fit and function. Your Podiatrist will then show you how to take it on and off.
Putting On: Ensure your heel is sitting at the back and bottom of the liner and close it firmly. Starting from the bottom and working your way up, fasten the straps, ensuring that they are firm. Do not disrupt your Moon Boot fit & alignment by removing the inner liner.
Taking Off: Open the five straps and then the liner. Slide your foot forward out of the Moon Boot. You may remove for showering or cover with a bag as prescribed by your My FootDr Podiatrist
Are Moon Boots Comfortable?
There is usually a short adjustment period while you get used to the feeling of wearing your CAM Walker – but even this isn’t necessarily uncomfortable, just very different. As your Moon Boot can help reduce pain, most people quickly find it is more comfortable with the CAM Walker than without.
Your Personalised Treatment Plan
Alongside your Moon Boot, it is likely that you will also be prescribed other treatment components to help maximise your recovery and manage your (often painful) symptoms. This may include a compression bandage, ice, pain medication, crutches, elevating the foot regularly, and rest. Your CAM Walker must be worn for the minimum number of weeks prescribed by your My FootDr Podiatrist.
When Should I Wear My Moon Boot?
Every injury is unique, as is the health and mobility requirements of each person. Your assessment with your Podiatrist takes into account your fracture or injury, health, medications and mobility requirements. Some fractures may require the use of your CAM Walker 24 hours per day, while others may be able to be taken off for sleeping. You must follow the advice given by your Podiatrist – this advice is provided to help you achieve the best healing outcomes in the shortest time.
Your injury may increase the risk of blood clot formation (Deep Vein Thrombosis). If you feel abnormal pain or swelling in your foot that does not seem related to your injury, remove the Moon Boot immediately and visit your nearest hospital or GP.
As the Moon Boot changes the way you move, please walk carefully and be cautious on slippery or uneven surfaces, and when climbing stairs. Constant, excessive weight may cause the breakdown of the Moon Boot. Driving with the CAM Walker is also not recommended.
The height of the Moon Boot and your altered walking style may create problems at other joints such as the knees, hips, or lower back as they are not used to your new gait. The risk of these issues may be reduced by wearing a supportive & cushioned shoe with a similar heel height to the Moon Boot on your unaffected side. For warmth and hygiene, you may wear a sock beneath the liner and over the compression. Do not remove the liner or any pads from the walker, these will be present for a reason to help your recovery. If required, you can return for a fit adjustment – just call and make an appointment with your Podiatrist.
When To Stop Using Your Moon Boot
Before you stop using your Moon Boot, you must return to My FootDr for your discharge and post-walker rehabilitation plan. Often, an x-ray and re-examination are required to gauge if sufficient healing has occurred, and hence it is safe for you to stop using your walker. If you stop using your walker too early, you may prolong your recovery.
How To Clean Your Moon Boot
As the liner of your Moon Boot is removable, you can safely hand wash it in warm water with a mild detergent and let it dry naturally. Do not machine wash or machine dry. Please ensure that it is completely dry before using it again. The outer component of the CAM Walker can be safely cleaned by wiping it down with mild soap and a damp cloth.
Many people also choose an odour eliminating spray for the inside of their liner between washes. With the right care, your Moon Boot can last many years and be used for multiple injuries. Please see the instructions on the liner of your walker for further care and cleaning information.
Can you drive with a Moon Boot?
Driving with a Moon Boot is not recommended as your breaking response time and foot mobility is hindered.
Are Moon Boots waterproof?
The exterior of Moon Boots are water-resistant but not waterproof, and should not be used to protect your cast during showers.
Do you sleep in a Moon Boot?
When your podiatrist is assessing your injury, they will decide when it is necessary for you to wear your moon boot. Some fractures may require the use of your moon boot 24 hours per day, while other injuries may allow you to take off your CAM Walker while sleeping. If you are required to wear your Moon Boot at night, to increase your comfort you may be able to loosen the straps that secure your boot.
Can you fly with a Moon Boot?
If you are concerned about your injury swelling during air travel it is best to talk with your podiatrist about their recommendations. Generally, flying with a Moon Boot is allowed on most airlines – provided there is no risk of swelling cutting off your circulation.
