Disclosed herein are systems and methods for determining alignment angles between a first prosthetic component and a second prosthetic component that are joinable together in a fixed orientation relative to each other, wherein the fixed orientation includes a first angle and optionally also a second angle that are perpendicular to each other, and wherein the first and/or second angles are selectable from a range of angles to provide a desired fixed orientation between the two prosthetic components. The system includes a magnet fixedly coupled to the first prosthetic component and one or more magnetic intensity sensors configured to be coupled to the second prosthetic component in a fixed orientation relative to the second prosthetic component such that the sensors are operable to sense a magnetic field of the magnet and produce an output signal in response to the strength of the sensed magnetic field. The system can include a processor operable to receive the output signals from the sensors and determine the first and/or second angles.

An ankle prosthesis can have a base and an upper hinge component that is pivotably attached to the base about an axis. First and second biasing elements can bias the upper hinge component in first and second rotational directions, respectively. At least one selectively extendable and retractable locking element can extend from one of the base and the upper hinge component and engage the other of the base and the upper hinge component to limit the pivotable movement of the upper hinge component.

A device includes a first member and a second member disposed in series along a longitudinal axis. The device also includes links coupling first joints of the first member to second joints of the second member. The first and second members and the links arranged to define a planar parallelogram linkage. The devices also include a resilient element disposed between the first member and the second member, the first member and the second member preloaded against the resilient element. The first member and the second member are preloaded to provide an arrangement of the first and the second joints in which a motion of the first joints with respect to the second joints is constrained to a direction substantially parallel to the longitudinal axis. The devices further include a sensor for generating a signal indicating a separation between the first member and the second member.

Powered limb prostheses with multi-stage transmissions are provided.

Prosthetic feet that allow for heel height adjustment and/or provide metatarsal joint functionality to more closely mimic natural human feet are provided. A prosthetic foot can include an ankle module having a locking mechanism configured to lock the heel at a particular height. The prosthetic foot can also include a toe region that adapts to varying heel heights. The ankle module and/or locking mechanism can be adjusted, controlled, and/or locked via a hydraulic mechanism. The toe region can curve upward relative to a portion of the foot proximal of the toe region.

The invention relates to a computer-implemented method for producing an orthopedic device. The method includes receiving at least one data set with patient data, processing the patient data in order to create a patient model, using the patient model to determine patient parameters, and generating a virtual representation of the orthopedic device while using the patient parameters and device parameters. The method further includes receiving at least one input from at least one user, modifying at least one of the patient parameters or device parameters on the basis of the input, and physically creating the orthopedic device.

In an embodiment, a prosthetic leg including a modular knee element coupled to a modular ankle element. The modular knee element includes a knee motor rotatable about an axis of a shaft in the knee motor. The modular ankle element includes a drive portion coupled to a surface-contacting portion via a pylon having a top and bottom end. The top end is coupled to the drive portion and the bottom end is coupled to the surface-contacting portion. The drive portion includes an ankle motor coupled to a rotary series elastic actuator (RSEA) and a first pulley coupled to the RSEA. The surface-contacting portion includes a hinge and a second pulley with a belt engaging at least a portion of at least one of the first and second pulley, and a modular foot element coupled to the bottom of the hinge.

The invention relates to a prosthetic foot comprising a base body having a front sole region, a heel body having a rear sole region, and a slot configured to receive at least one spring element, in particular at least one leaf spring, the spring element configured to be pushed or inserted into the slot. In a disposed state, the spring element engages in the base body and the heel body such that the heel body is spring mounted relative to the base body.

An adjustable socket system includes first and second shell components and first and second longitudinal supports connected to a base. The socket system is movable between an open configuration to loosen the fit of the socket system, and a closed configuration to secure the fit of the socket system on residual limb received therein. A tightening system includes a tensioning unit having a handle defining a moment arm rotatable about a rotation axis, and a tensioning element operatively coupled to the handle via a movable connection point located and protected between the first shell component and the first support and to the shell components via a control point. Rotation of the handle displaces the movable connection point and the tensioning element relative to the control point to move the socket system to the closed configuration.

A method for adjusting a flexion angle of a prosthetic ankle includes a user adjusting a relative angle between first and second coupling members of the prosthetic ankle using a flexion angle adjustment mechanism of the prosthetic ankle that requires no tools to adjust.
