VACOhand therapy concept has the Flex product. It is use for dynamic, functional treatment of flexor tendon injuries to the hand. With distinctive vacuum cushion, it adapts its shape to the hand of the patient structurally and precisely just like a handmade orthoses or splint. The traction of the balancers can be adjusted, and is constant over the entire movement. Like all the products the angles at the wrist and the knuckle joints can be individually adjusted. Its modular joint allows fixation in any position, but can also be adjusted to allow dorsiflexion and palmer flexion for early functional therapy.
