Dynamic cushion heel-ankle-foot orthosis
A dynamic cushion heel-ankle-foot orthosis system is configured to provide controlled tibial progression in a human user. The dynamic cushion heel-ankle-foot orthosis system includes a leg calf shell further comprising a leg calf shell plantar flexion ridge at a lowermost point. A boot shell is rotatably connected to the leg calf shell and further comprising a boot shell plantar flexion ridge at an uppermost point. The boot shell plantar flexion ridge contacts the leg calf shell plantar flexion ridge at a plantar flexion ridges region and rotates no further.
