Abstract
An orthosis developed in Dokuz Eylül University (DEU) at the School of Physical Therapy and Rehabilitation, Department of Orthotics and Prostheticsis is described. It is applied as a non‐invasive device attached to the distal ring of the Ilizarov external fixator to keep the ankle joint in a neutral position and prevent ankle equinus during tibial lengthening with Ilizarov technique. This minimises additional invasive techniques such as heel cord release and prophylactic pinning of the heel and the foot, and manipulation under anaesthesia. It may also be detached by the physiotherapist or patient when physical therapy is needed during the lengthening procedure.
