UTX-Stabil orthosis is made for patients that cannot use UTX-Swing-type orthosis because of knee or hip dysfunctions. In the Stabil the knee is locked during walking. The joint is opened when sitting down using the PUMA (Push Manual Release System) situated on a lateral upright. The brace has a wire on the medial side in order to increase sideways stability. A double sided ankle joint is also available as an accessory.
