Medgadget reports that the FDA approved Small Bone Innovations' implantable ankle.
This implantable total ankle replacement system is intended for use in patients where there is severe arthritis or other deformities that hinder the range of motion of the joint.
Small Bone Innovations claims that this design of the STAR system is the first of its kind because it relies on movable bearings that glide across the surface of polyethylene. The advantage is that this still affords some joint movement as opposed to traditional fusion surgeries that join the tibia to the talus bone for additional strength but severely limit motion.
