A hinge is configured for selectively retaining and removing at least one rotation stop without a supplementary tool. The hinge includes a locking device having at least one lever arranged to selectively rotate a retaining member for engagement and disengagement with the at least one rotation stop. The retaining member forms an abutment portion extending from a first portion and a second portion extending from the abutment portion. A non-abutment portion is located opposite the abutment portion along a same segment of the axis of the retaining member.

A knee brace with an articulation assembly connectable with a first cuff movable with respect to the articulation assembly about a first location defining a first pivot axis between the first cuff and articulation assembly, and movable about a second location defining a first rotation axis between the first cuff and articulation assembly. The knee brace may have a second cuff connectable with the articulation assembly and movable with respect to the articulation assembly about a third location defining a second pivot axis between the second cuff and articulation assembly. The second cuff is movable about a fourth location defining a second rotation axis between the second cuff and articulation assembly. The first pivot axis and first rotation axis may intersect each other or be offset from intersecting each other, the second pivot axis and second rotation axis may intersect each other or be offset from intersecting.

A customizable knee brace for use in the treatment of osteoarthritis is provided. The customizable knee brace includes a lateral upright. The lateral upright includes at least a first semi-rigid support, a second semi-rigid support, and a hinge physically coupling the first semi-rigid support and the second semi-rigid support. The customizable knee brace further includes a thigh cuff constructed of formable material and coupled to the first semi-rigid support. The customizable knee brace further includes a shin cuff constructed of formable material and coupled to the second semi-rigid support. The customizable knee brace further includes an elastomeric web framework coupled to the lateral upright and configured to secure an area of a knee of a patient when wearing the customizable knee brace. The customizable knee brace further includes at least one tensioning element configured to adjust a tension of the elastomeric web framework.

A hinge brace system including a first upright, a second upright, a gear, a cam, and a pin associated with each of the first upright and second upright, and a dial assembly opposite the gear housing. The dial assembly includes a dial base and a dial flange, the dial flange configured to rotatably step the cam, causing the gear to step about the gear housing. The gear further includes a limit marking, the limit marking extruding from the gear into a slot of the upright and preventing the upright from travelling beyond a desired angle, the angle preventing rotation of the hinge brace system in at least one of extension and flexion.

A hinge which can be included on a brace is disclosed. The hinge can include a first arm, a second arm, and a hinge plate. The first and second arms can be connected to the hinge plate for rotation about first and second axes, respectively. The hinge plate can include an internally threaded aperture. The hinge can also include a force application assembly and an adjustment assembly. The adjustment assembly can include an externally threaded lead screw engaged with the internally threaded aperture, and having a medial end connected to the force application assembly and a keyed bore. The adjustment assembly can include a drive key having a keyed shaft slidingly engaged with the keyed bore and a knob connected to the drive key such that rotation of the knob causes displacement of the force application assembly.

Methods, devices, and systems are described for a foot suspension system configured to offload weight from a foot of a user. The foot suspension system includes a boot shaped to receive at least a part of the foot of the user, the boot including a bottom inner surface. The foot suspension system further includes a sleeve configured to secure to a lower appendage of the user to assist with suspending at least the part of the foot above the bottom inner surface of the boot. The foot suspension system further comprises at least one vertical bar with a first end positioned adjacent to the boot and a second end of the at least one vertical bar positioned

An eccentric and polycentric articulated tensioning joint applied to an orthopedic brace with adjustable angular excursion placed in correspondence of body joints comprises two bars each hinged to a rotation pin, wherein said rotation pins are constrained parallel to each other at a predefined distance, said two bars being connected to each other by means of respective semi-circular toothed profiles present on each bar, so as to be set in synchronous motion relative to each other. Said two bars are associated with a respective pair of loop elements, which are kinetically connected to said bars in such a way as to impart thereto the same rotational movements and partially transform them into relative translational movements along the longitudinal axes of each of the bars themselves, in order to effect linear movements of reciprocal distancing or nearing relative to the rotation centres thereof located on said pins.

An adjustable tensioning device capable of providing and holding high tensions needed for medical devices, prosthetics, and orthotics.

An adjustable tension knee brace for unloading weight from a knee joint afflicted with osteoarthritis, thus reducing pain and improving mobility, comprising: an upper and lower frame connected by an unloading hinge assembly, optionally comprising a sensor and processor allowing for remote or automatic control of brace tension. In embodiments, the brace includes a user mechanism that is capable of adjusting a tensioning element while the brace is being worn. In other embodiments, electronic motors, sensors, and indicators may be included in the brace to improve brace performance and user interaction.

Gearwheel transmission comprising a first stage and a second stage, the second stage being a differential gearing comprising a planetary gear train system which is executed in a quasi duplicated form, wherein a first component is forming a torque resisting means, wherein a second component is interconnected or interacting with an output shaft, the overall transmission efficiency in the first stage being higher than in the second stage and/or the overall capacity for transmitting torque in the second stage being higher than in the first stage.
