Bone anchor assemblies and related methods are disclosed herein that can provide for improved fixation of a primary bone anchor. A bone anchor assembly can include a wing with a distal portion that can define a plurality of auxiliary bone anchor openings. Each auxiliary bone anchor opening can receive an auxiliary bone anchor that can augment fixation of a primary bone anchor of the bone anchor assembly. The plurality of auxiliary bone anchor openings can be oriented such that, when the wing is coupled to a primary bone anchor assembly of a vertebral level in a first configuration, at least one auxiliary bone anchor can be driven to extend across a facet plane of the vertebral level and, when coupled in a second configuration, each auxiliary bone anchor received within the wing can be driven to conform to the vertebral level.

Devices and processes used to treat ankle conditions. More specifically, the present disclosure relates to a brace and the corresponding method of use to treat ankle conditions by stretching the Gastrocnemius muscle, soleus muscle, and plantaris muscle.

A walking assistance apparatus includes a frame configured to be mounted on a lower leg of a user, a sole support connected to the frame and configured to support a lower side of a foot of the user, an actuator mounted on the frame, and a pusher configured to receive a power from the actuator and push the ground.

A foot brace to manage foot supination includes a planar member, the planar member has a proximal end and a distal end, an upper portion, a middle portion, and a lower portion. The middle portion can include an opening for the heel to protrude. A leg fastener at the proximal end of the planar member allows securing the foot brace to the leg. A foot strap at the distal end allows securing the foot brace to the midfoot or the forefoot. On an inner surface of the planar member adjacent to the distal end can be provided multi-tier cushions pads, wherein the multi-tier cushion pads can put an upward force on the arch of the foot when the foot with the foot brace is placed on the floor. The number of cushion pads can be changed for optimum stabilization effect in foot supination.

The present disclosure is relates to an orthosis device. The orthosis device, in one embodiment, includes an actuator housing, and an electric motor coupled to the actuator housing, the electric motor including a motor stator and a motor rotor, and the electric motor further having high output torque. The orthosis device, in this embodiment, further includes a low-ratio transmission coupled to the actuator housing, the transmission including a gear system coupled to the actuator housing, and a drive system coupling the electric motor and the gear system, wherein a combination of the electric motor and transmission provide a user backdrivable orthosis device.

Artificial limbs and joints that behave like biological limbs and joints employ a synthetic actuator which consumes negligible power when exerting zero force, consumes negligible power when outputting force at constant length (isometric) and while performing dissipative, nonconservative work, is capable of independently engaging flexion and extension tendon-like, series springs, is capable of independently varying joint position and stiffness, and exploits series elasticity for mechanical power amplification.

An orthopedic device is arranged as a lightweight ankle-foot orthosis providing dynamic support for drop foot or related disorders requiring dorsiflexion. The orthopedic device includes a main support adapted to secure about a lower leg, a strap assembly having a first portion coupling to the main support, and a second portion arranged to be drawn therefrom, and an anchor for receiving and attaching to the second portion of the strap assembly. The location of the anchor along a foot component enables increased medial-lateral control, and the arrangement of the strap assembly permits dorsiflexion during swing phase of a user's gait.

Methods and apparatus for human anatomical orthoses. In one embodiment, an orthoses is disclosed that has been integrated into a sock and includes a tensioning element that is configured to keep the top portion of the sock at or above a user's calf muscle, a rotary tensioning mechanism disposed adjacent to the top portion of the sock, a support cable that is weaved within the body of the sock such that the support cable is maintained in close proximity with a user's leg when tension is applied thereto, and a supporting structure that is coupled to the support cable, the supporting structure being disposed adjacent to a user's toes. Methods of manufacturing and using the aforementioned orthoses is also disclosed.

An adjustable knee ankle foot orthosis 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.

Provided is a toe stimulus imparting supporter configured to impart a stimulus to toes in a state where the toes are inserted into the toe stimulus imparting supporter. The toe stimulus imparting supporter includes: a body portion formed of an elastic stretchable member having a strip shape; toe inserting portions through which the toes are insertable, the toe inserting portions formed in both end portions of the body portion in a longitudinal direction of the body portion; and indirect stimulus imparting protruding portions formed on both end portions of the body portion in a protruding manner outward from the body portion.
