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

A prosthetic foot including a continuous body extending from a proximal end to a distal end. The body includes an anterior surface, a posterior surface opposite the anterior surface, and a fin on the posterior surface. A prosthetic foot can include a first footplate and a second footplate. The first footplate extends between a proximal portion and a distal portion. The proximal and distal portions of the first footplate are configured to operatively engage a support surface during ambulation. The second footplate extends between a proximal portion and a distal portion. The distal portion of the second footplate is coupled to the first footplate at an intermediate location between the proximal and distal portions of the first footplate. The second footplate incudes an anterior surface, a posterior surface opposite the anterior surface, and a fin on the posterior surface.

Prosthetic foot with layers of fibrous material

A traction system for an ambulatory support such as a prosthetic foot blade or a crutch includes a sole plate, a latch assembly, and a strap. The sole plate is couplable to a distal end of the ambulatory support to extend under a bottom side of the ambulatory support and a latch assembly. The latch assembly includes a front catch and a rear catch both fixable at a top side of the ambulatory support with the front catch nearer to the distal end of the ambulatory support than the rear catch, and a lever having a front end and a rear end, the front end releasably latchable to the front catch and the rear end releasably latchable to the rear catch when the lever is pivoted about the latched front end. The strap is secured to the lever and to the sole plate.

Traction system for an ambulatory support

Various features for improving the performance of crutches are provided. A crutch can flex at one or more locations or include composite material to provide energy storage and return to the user during ambulation. In some aspects, a crutch is provided that can propel the user forward during ambulation. The crutch can be hollow at one or more locations to allow for increased flexibility and narrower at one or more locations to enhance springiness of the crutch.

Crutch with energy storage and energy return

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

Prosthetic feet that provide improved rollover and performance are provided. A prosthetic foot can include a lower foot member extending from a heel end to a toe end, a second foot member disposed above the lower foot member, and an optional third foot member disposed above the second foot member. The second foot member is tapered such that its thickness decreases toward the proximal end. Optionally, the second foot member can taper toward its distal end as well as toward its proximal end from an intermediate location on the second foot member. The third foot member can be tapered such that its thickness decreases toward the distal end. There can be a gap between a distal end of the third foot member and the second foot member that closes during dorsiflexion of the prosthetic foot during use and provides dynamic stiffness control to the prosthetic foot.
