A bone correction system is configured to attach to the medial cuneiform and the first metatarsal of a patient's foot in a deformed configuration. An articulation joint is configured to rotate and angulate the first metatarsal with respect to the medial cuneiform. A translation assembly is configured to cause the first metatarsal to travel toward and / or against the medial cuneiform. Thus, the bone correction system is configured to iterate the patient's foot from the deformed configuration to a corrected configuration. A bone plate can permanently fix the medial cuneiform and the first metatarsal in the corrected configuration.

A device for exercising / strengthening feet includes a left pad for supporting and exercising a left foot and a right pad for supporting and exercising a right foot, each pad comprising a rear portion to support the hindfoot thereon and a front portion to support the midfoot and the forefoot thereon, the front portion comprising a hallux portion to support the hallux. A notch is positioned adjacent to the hallux portion and underneath the first metatarsophalangeal (MTP) joint of the foot. The hallux portion and the notch are configured such that at least a portion of the first MTP joint is unsupported by the front portion to reduce a pressure experienced by the first MTP joint when the hindfoot is supported on the heel portion and to provide increased plantarflexion of the first metatarsal bone of the foot when the hindfoot is raised and unsupported by the rear portion.

A variety of surgical procedures may be performed on the bones of the foot, such as on one or more lesser metatarsals of the foot positioned laterally of the first metatarsal. For example, a surgical procedure may involve cutting an end of one or both of a second metatarsal and an intermediate cuneiform and / or cutting an end of one or both of a third metatarsal and a lateral cuneiform. The tarsometatarsal joints defined be one or both sets of bones may be cut to treat an arthritic joint, metatarsus adductus, and / or other clinical condition. In any case, various surgical instruments can be utilized during a procedure to help increase the accuracy and repeatability of the procedure patient-to-patient, improving overall patient outcomes. For example, one or more cut guides, compressor-distractor devices, and / or other instruments designed to accommodate the specific anatomical conditions of the procedure being performed may be utilized during procedure.

This utility model relates to the field of thermal insulation technology, specifically to an ergonomically designed heated sock with an inner lining. The sock includes an inner lining, one side of which is fixedly connected to a heating wire for foot heating. The heating wire includes a segment located in the arch of the foot, and the other end of the arch segment is fixedly connected to a segment that avoids the sesamoid bone of the first metatarsal bone. The beneficial effects of this device are: the arch segment of the heating wire is routed in the concave arch of the foot, providing warmth and preventing foot discomfort; the segment that avoids the sesamoid bone protrusion prevents the heating wire from compressing the sesamoid bone, improving foot comfort. Since the proximal and distal phalanges of the human foot protrude upwards through the middle phalanx, forming a continuous concave area between the sole and toes, the middle phalanx segment and the middle phalanx loop segment are routed in this concave area, providing warmth and preventing the heating wire from compressing the toes, further enhancing comfort.
