The Aircast Airlift PTTD Ankle Brace is specifically for the Posterior Tibial Tendon Dysfunction on the inside (medial side) of the ankle.

The AirLift PTTD brace is designed to provide arch support with an adjustable arch aircell for posterior tibial tendon dysfunction or for early signs and symptoms of the adult acquired flat foot. Depending on the severity of the condition, it can be prescribed for use as part of a conservative treatment to stabilise the condition and help prevent its degeneration, or post-surgically and during rehabilitation. Foot support and ankle stabilisation are provided by the AirLift integrated aircell and semi-rigid shells. The aircell, located under the foot arch, is adjustable using the Hand Bulb (included with the brace). When inflated, the aircell can accommodate variances in arch shapes and heights and comfortably lifts the foot arch to achieve a more natural foot position. For ease-of-use, aircell inflation can be adjusted while wearing foot wear. The semi-rigid shells are anatomically designed to the shape of the ankle for secure support and stabilisation. These shells help realign the ankle and support the patient.

The Aircast AirLift PTTD Ankle Brace is designed for easy application and adjustment. The ankle brace uses an innovative rear entry design which allows the patient to slip their foot into the back of the brace. Two straps secure the brace and can be used to adjust fit. These patient-friendly design elements make the AirLift easier to apply than custom braces, eliminate time consuming lacing, and help improve patient compliance.

- Adjustable arch aircell for individual support and comfort.
- Anatomically designed shells for secure ankle stability.
- The PTTD ankle brace has a rear entry design and simple two strap application promote ease of use and compliance.

- For posterior tibialis tendon dysfunction or adult acquired flat foot, post-op and rehabilitation.

    Much more effective than an orthotic insole

    Posted by Jody on 9th Mar 2010

    This is much more effective than the orthotic insole prescribed by the hospital, reducing the pain in my feet and legs by up to 90%. Would buy again.
