The Step-On Ankle Hinge 100 / Extension is a low-profile, lightweight, yet robust unilateral hinge made from stainless steel. It is designed for ease of use by technicians in the construction of custom-made AFOs and/or KAFOs, with simple functionality. The hinge includes a stainless steel extension component, enabling orthotists to design AFOs using materials of their choice. It also features a spring mechanism that enables the technician to control the patient’s dorsiflexion or plantarflexion. 

The Step-On Ankle Hinge 100 / Extension allows a total range of motion (ROM) of 33°, which can be configured, for example, as 22° of dorsiflexion and 11° of plantarflexion. This range of motion is adjustable and can be modified to meet the specific needs of both the technician and the patient.
