A prosthetic foot plate can have adjustable flexibility in the toe region, the metatarsal area, and/or the arch to accommodate different heights to which a heel region of the prosthetic foot plate is raised. The adjustable flexibility can be provided by materials of different stiffness and/or different physical structures of one or more locations on the prosthetic foot plate. In another variation, the adjustability in the toe region can be provided by a link between the toe region and ankle of the prosthetic foot. The link can be actuated to adjust an orientation of the toe region and/or the metatarsal region in any heel-height setting.

Prosthetic feet with increased flexibility to accommodate different heel heights

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.

Prosthetic feet having heel height adjustability

A vertical suspension system for a prosthetic foot includes a first member operatively coupleable to an amputee's residual leg. The suspension system can also include a second member coupleable to a prosthetic foot. One or more upper leaf springs and one or more lower leaf springs extend between and are attached to the first and second members such that at least one of the ends of each leaf spring is rotationally fixed to the first or second members, where the upper an lower leaf springs are spaced apart from each other.

Frictionless vertical suspension mechanism for prosthetic feet

A prosthetic ankle module allows for translational and/or rotational movement of a prosthetic foot relative to an adapter. The ankle module can include a four-bar linkage assembly. Links of the linkage assembly can be arranged in various configurations, e.g., parallel or non-parallel and having equal or non-equal lengths, to provide different functions and benefits, e.g., dorsiflexion, plantar flexion, vertical shock absorption, inversion, eversion, and/or rotation about the sagittal axis. Other types of linkage assemblies are also possible. A prosthetic foot can further include a support spring to limit the range of motion of the adapter in use.
