1. An apparatus configured to apply traction to a big toe of a patient's foot at a desired adduction angle and a desired dorsiflexion angle, for use in treating a bunion, said apparatus comprising:
a toe trap configured to be releasably secured to at least a distal phalange of the big toe of the patient's foot, said toe trap comprising a cable;
a shoe portion, said shoe portion comprising:
a sole, said sole comprising a substantially flat interior surface configured to support a bottom of the patient's foot;
a pair of flaps each extending from a respective side of said sole an amount to overlap over the top of the patient's foot;
a first strap and a second strap, said first and second straps configured to secure the patient's foot to said sole;
a support bracket, said support bracket comprising a first portion and a second portion, said first portion of said support bracket mounted to pivot with respect to said shoe portion at a pivot axis, to adjust an adduction angle of said cable with respect to an axial direction of said sole, said pivot axis being substantially perpendicular to said substantially flat interior surface of said sole, said first portion of said support bracket configured to extend substantially perpendicular to said pivot axis, and said second portion of said support bracket configured to extend substantially parallel to said pivot axis and to terminate at an elevated position with respect to said sole;
an adjustment member, said adjustment member mounted to slide relative to said second portion, to slide substantially parallel to said pivot axis to adjust a dorsiflexion angle provided by said cable independent of said adduction angle; wherein a portion of said toe trap is supported by said adjustment member;
a securement apparatus configured to releasably secure said first portion of said support bracket at said pivot axis with respect to said shoe portion, at a first pivot position to provide a first adduction angle for said cable, and at least a second pivot position to provide a second adduction angle for said cable;
means for releasably securing said adjustment member with respect to said second portion of said support bracket at a first elevated position for providing a first dorsiflexion angle for said cable to reposition the big toe to a first repositioned angle with respect to said sole, and at least a second elevated position for providing a second dorsiflexion angle for said cable to reposition the big toe at a second repositioned angle with respect to said sole;
means for adjusting an amount of tension in said cable; and
wherein said first strap is configured to counter said amount of tension in said cable with respect to said adduction angle, whereby said first strap is securable over the top of the patient's foot in proximity to the ankle of the patient's foot; and
wherein said second strap is configured to counter said amount of tension in said cable with respect to each of said first and second dorsiflexion angles to immobilize the patient's foot, whereby said second strap is securable over the top of the patient's foot in proximity to the toes of the patient's foot, such that the amount of tension in said cable at each of said first and second dorsiflexion angles repositions only the big toe with respect to said sole.
