The WB107 serves orthopaedic clinics, fracture clinics, post-surgical services and physiotherapy departments that manage injuries to the ankle and foot. It is indicated for Grade II or III ankle sprains; stable fractures of the fibula, talus, calcaneus, and medial malleolus; surgery on ligaments, soft tissue, and tendons; and injuries to the forefoot or midfoot. One boot spans all of them, which keeps a service's range simple.
The air system gives the boot its character. The medical air pump can help decrease heel-strike force on the calcaneus, and inflatable air cells are available as an option for further support, reducing swelling and spreading pressure evenly. Swelling is a concern after injury or surgery, and the air cells help reduce it. Together, the pump and the cells make up the air system of the boot. The cells also provide even pressure.
Recovery depends on walking, and the underfoot design supports it. The rocker bottom encourages a natural gait; the boot aids propulsion and substitutes for ankle motion, and the low-profile footbed height is designed to minimise leg-length discrepancy. The anatomical frame is lightweight and can help increase compression, immobilisation and stability of the calf, ankle and foot.
Heights of 11 inches and 17 inches let a service match the boot to the leg length that needs protection, and sizes S, M and L match it to the foot. A fracture clinic, a post-surgical ward and a physiotherapy department can therefore stock the same boot for different patients.
