Abstract
A low profile prosthetic foot comprises a foot member extending at an incline from an anterior portion to a posterior portion thereof and configured to flex during motion, and an adapter mounted solely at a posterior section thereof to the posterior portion of the foot member so that the adapter's anterior section can move relative to the foot member and “roll-up” onto the foot member during motion.
Claims11
In combination, an elongate foot support adapted for use in a prosthetic foot and a monolithic adapter mounted to a posterior portion of the foot support, the adapter comprising a pyramid vertically oriented with respect to a support surface on which the foot rests, the pyramid extending along an axis at a non-perpendicular angle relative to the base of the adapter, the adapter having a base with a length contacting the foot support, said base being inclined along substantially the entire length of the adapter from a rearmost end to a frontmost end of the adapter at a constant angle relative to the pyramid and to the support surface, the base in contact with the foot support along substantially the entire length of the adapter from the rearmost end to the frontmost end of the adapter during motion of the prosthetic foot through a complete gait cycle of the prosthetic foot, the base being monolithic with a curved portion at an anterior section of the adapter, the base defining an edge at the anterior section having a radius of curvature of between about 0.5 cm and 4 cm.
A low profile prosthetic foot comprising:
- a foot support extending between a front end and a rear end and having an anterior portion and a posterior portion, the posterior portion inclined at an angle relative to a support surface;
- and
- a monolithic adapter comprising a pyramid vertically oriented with respect to the support surface, the pyramid extending along an axis at a non-perpendicular angle relative to a base of the adapter, the adapter mounted to the posterior portion of the foot support and having an anterior section, a posterior section, and the base, wherein at least a portion of the base contacts the posterior portion of the foot support, the base being inclined along substantially the entire length of the adapter from a rearmost end to a frontmost end of the adapter at a constant angle relative to the pyramid and to the support surface, the base in contact with the foot support along substantially the entire length of the adapter from the rearmost end to the frontmost end of the adapter during motion of the prosthetic foot through a complete gait cycle of the prosthetic foot, the base being monolithic with a curved section at the anterior section of the adapter, the base defining an edge at the anterior section having a radius of curvature of between about 0.5 cm and 4 cm, the anterior section configured to move relative to the foot support.
