Abstract: The invention relates to a lockable hinge for an orthosis. The lockable hinge comprises a first side bar and a second side bar, a bridging element and a locking mechanism. A first end of the first side bar is fixedly mounted to a first portion of the bridging element, and a first end of the second side bar is rotatably mounted to a second portion of the bridging element. The locking mechanism is supported by the first side bar, and the locking mechanism comprises a locking block being slidable along the longitudinal extension of the first side bar between a locked position and an unlocked position. In the locked position the locking block engages by wedging between the second side bar and the bridging element, whereby the second side bar in the locked position is fixedly aligned with the first side bar.

Abstract: A leg brace and method for forming thereof is provided. The brace includes a frame formed of at least a thermoplastic material. A harness is fixed to the frame, the harness being retained adjacent a user's leg during use. The leg brace may be further formed with a tibial restricting portion running along and substantially parallel to the medial shaft of a user's tibia during use, thereby preventing any unwanted movement or rotation of the user's tibia. The brace is formed by forming a brace core of a mixture of a thermoplastic material and a blowing agent and then placing a composite material in contact with the core. Next, the core and composite material are heated in a mold to a temperature sufficient to allow the thermoplastic material to become molten, causing the blowing agent to expand and force the composite material against an interior wall of the mold cavity and to form a thermoplastic cellular core.
