Dorsiflexion and plantar flexion refer to extension or flexion of the foot at the ankle. These terms refer to flexion between the foot and the body's dorsal surface, considered the front of the leg, and flexion between the foot and the body's plantar surface, considered the back of the leg.
Orthopedic plate for use in the MTP joint
The present invention is a MTP plate that has a first embodiment with a profile having bilateral mirror symmetry of the about a transverse plane with an angle of about 5° for dorsiflexion and an angle of about 10° for valgus. Both ends of the plate include a central arm having a slot for compression and two offset arms having offset ears with locking screw holes that provide for multiplanar compressive fixation. The bone contacting surface of the plate is radiused to allow the plate to be in snug contact with the bone. In a second embodiment of the plate for revision surgery, the proximal end of the plate includes a metatarsal extension and the plate has a central locking hole for securing bone graft.

Prosthetic ankle and foot combination
A prosthetic ankle and foot combination has an ankle joint mechanism constructed to allow damped rotational movement of a foot component relative to a shin component. The mechanism provides a continuous hydraulically damped range of ankle motion during walking with dynamically variable damping resistances, and with independent variation of damping resistances in the plantarflexion and dorsiflexion directions. An electronic control system coupled to the ankle joint mechanism includes at least one sensor for generating signals indicative of a kinetic or kinematic parameter of locomotion and / or walking environment, the mechanism and the control system being arranged such that the damping resistances effective over the range of motion of the ankle are adapted automatically in response to such signals. Single and dual piston hydraulic damping arrangements are disclosed, including arrangements allowing independent heel-height adjustment.

Boot for treatment of plantar fasciitis
InactiveUS20050131324A1Avoid attenuationMinimize further damageNon-surgical orthopedic devicesGaitFoot dorsiflexion
A boot for use in the treatment of plantar fasciitis. The boot places the foot in the desired amount of dorsiflexion, preferably from 5° to 20°, which stretches the Achilles tendon and is believed to prevent the shortening of the plantar fascia. The boot also provides protection for the foot while walking or engaging in other load bearing activities, to minimize further damage to and / or inflammation of the plantar fascia. The boot has a sole that is shaped to allow as close to a natural walking gait as possible while maintaining the foot in the desired degree of dorsiflexion. Preferably, the amount of dorsiflexion of the foot is controlled through the addition wedges on the base of the boot.
