An orthopedic device that includes a foot part, a lower-leg part, and a thigh part. The foot part is connected to the lower-leg part for pivoting about a first pivot axis by an ankle joint. The lower-leg part is connected to the thigh part for pivoting about a second pivot axis by a knee joint. The foot part is connected to the thigh part by a force-transmitting apparatus. The force-transmitting apparatus causes a dorsal flexion of the foot part in the event of a knee flexion over a first knee flexion angle range and causes a plantar flexion of the foot part in the event of further knee flexion after a knee flexion limit angle has been exceeded.

A movable joint for use in a prosthetic or orthopedic system includes first and second joint sections arranged to rotate relative to one another. At least one shaft member is attached to and arranged to rotate relative to the first or second joint sections. A translating member is attached to the at least one shaft member. Translation of the translating member along a length of the at least one shaft member drives rotation of at least the first joint section and the second joint section.

The invention relates to an orthopedic joint with a first component, a second component that is arranged on the first component such that it can be swiveled about a swivel axis, and at least one damper that is configured and arranged to damp a swiveling of the first component relative to the second component, and an actuator for swiveling the first component relative to the second component in at least one direction. According to the invention, the actuator is arranged on the first component or the second component on a medial or lateral side such that it can be detached.

The invention relates to a thigh prosthetic component for connecting to a thigh shaft, having a knee joint that can be pivoted between a stance position and a swing position and has a proximal knee joint upper part and a distal knee joint lower part which are connected by a ventral articulated arm and a dorsal articulated arm, wherein the ventral articulated arm is articulated to the proximal knee joint upper part via a ventral, upper knee joint axis, and is articulated to the distal knee joint lower part via a ventral lower knee joint axis, and the dorsal articulated arm is articulated to the proximal knee joint upper part via a dorsal, upper knee joint axis, and is articulated to the distal knee joint lower part via a dorsal lower knee joint axis, and an ankle for the pivotable connection of a foot part to a lower leg unit connected to the knee joint. To provide a thigh prosthetic component that enables a natural gait pattern and is more energy-efficient and stable for the patient, it is provided that the lower leg unit has a ventral connecting element and dorsal connecting element designed to transmit thrust and traction, wherein the ventral connecting element is pivoted at one end to the foot part by a ventral ankle axis and at the other end to the distal knee joint lower part, and the dorsal connecting element is articulated at one end to the foot part by a dorsal ankle axis and at the other end to the proximal knee joint upper part and the dorsal articulated arm by the dorsal upper knee joint axis such that an adjustment of the knee joint from the stance position into the swing position causes a dorsal extension of the foot part.

An orthopedic device for the orthotic or prosthetic provision of a patient. The orthopedic device includes a knee joint which has a proximal upper part and a distal lower part arranged pivotably thereon, an ankle joint, a pivoted foot part which can be fastened distally to the ankle joint, and a shin part arranged between the ankle joint and the knee joint. The upper part of the knee joint or a thigh part fastened thereto that can be attached to the patient's body and is coupled with the foot part by a force transfer device, which causes a plantar flexion of the foot part when a knee is flexed.

A lower limb modular prosthetic system that may be fabricated by a 3D printer capable of printing with composite fiber filament, nylon, or metal. The production process may include a 3D printer that is capable of routing fiber in specifically programmed patterns. The components of the prosthetic system may be designed for direct patient end-use, and may be energy returning in nature.

The invention relates to an orthopaedic device for the orthotic or prosthetic provision of a patient witha knee joint (10), which has a proximal upper part (11) and a distal lower part (13) arranged pivotably thereon, an ankle joint (20), a pivoted foot part (23) which can be fastened distally to the ankle joint (20), anda shin part (14) arranged between the ankle joint (20) and the knee joint (10), wherein the upper part (11) of the knee joint (10) or a thigh part fastened thereto that can be attached to the patient's body is coupled with the foot part (23) by means of a force transfer device (3; 30, 31, 32, 35; 40, 41, 42), which causes a plantar flexion of the foot part (23) when a knee is flexed.

A prosthetic leg knee joint includes a thigh connection part that is provided on the thigh side, a lower leg part that is provided rotatably around a knee shaft connected to the thigh connection part, a four-bar link mechanism that sets an instant center S whose relative position with respect to the thigh connection part is substantially constant regardless of the relative position between the thigh connection part and the lower leg part, and a braking unit that brakes the movement of the lower leg part in accordance with the relative position between the instance center S set by the four-bar link mechanism and the lower leg part.

A device for fixing two orthopedic components to one another includes a receiving element arranged on a first orthopedic component, which receiving element has a receptacle and includes a connecting element arranged on a second orthopedic component. The connecting element has a connector. The connector can be inserted into the receptacle and is coupled with the receiving element in a tensile force, compressive force, and torque-transmitting manner. At least one flow- and/or data-transmitting contact is arranged on the connecting element and the receiving element so as to correspond to one another, which form an electrical and/or data-transmitting connection with one another in a fixed state of the orthopedic components.

An intracorporeal portion of a percutaneous device for a joint disarticulation prosthesis or joint replacement prosthesis, the intracorporeal portion having an extracorporeal portion or having means for rigidly coupling directly to an extracorporeal portion, the extracorporeal portion being for location exterior to the skin, the intracorporeal portion having an articulating component for articulating with an articulating surface, wherein the articulating component is intracorporeal when installed in a human or animal subject.
