Ankle encompassing pressure orthosis
First Claim
1. A custom fitted brace for limiting eversion and inversion of an ankle and a foot and allowing dorsiflexion and plantar flexion of the ankle and the foot, which comprises:
- a firm anterior support means to be mounted adjacent to and conform to an anterior portion of the ankle, wherein the anterior support means extends only slightly outward away from the ankle over the top of the foot so as to allow dorsiflexion of the foot;
a firm posterior support means connected by a quick-release rivet to the anterior support means and to be mounted adjacent to and conform to a posterior portion of the ankle, wherein the anterior support means and the posterior support means together extend downward beyond the malleoli of the ankle and provide encompassing pressure around the circumference of the ankle and the foot.

Abstract
A custom fitted ankle brace (10) and a process for constructing the brace is described. The brace is comprised of anterior and posterior supports (12 and 16) connected together at their distal ends (12B and 16B) by pivot pins (22). The anterior and posterior supports both have arcuate sidewalls (12C and 16C) which form openings (14 and 18). When the brace is in the closed position around the ankle (102), the sidewall of the posterior support overlaps the sidewall of the anterior support and the opening of the anterior support is adjacent the achilles tendon of the ankle. The anterior support has a cushion (26) adjacent the inside surface (12H) to increase the user'"'"'s comfort. To apply the brace, the proximal ends (12A and 16A) of the supports are pulled apart and the user (100) inserts his foot (104) into the brace and pulls the brace into position around his ankle. The brace is then secured on the ankle by a securing strap ( 28) extending around the proximal end of the supports. To construct the brace, supports are fabricated according to the user'"'"'s measurements, preferably using patterns (34 and 36). The supports are then heated and formed onto a cast (32) of the user'"'"'s ankle and foot. The anterior support is formed first and the posterior support is formed over the anterior support. The supports are then removed from the cast and connected together.

19. A custom fitted brace for limiting eversion and inversion of an ankle and a foot which are attached to a leg and allowing dorsiflexion and plantar flexion of the ankle and the foot, which comprises:
-
(a) a firm anterior support means to be mounted adjacent to and conform to an anterior portion of the ankle, the anterior support means having an arcuate sidewall between a proximal open end and a distal open end along and around a longitudinal axis of the leg wherein the arcuate sidewall at the distal end extends only slightly outward away from the ankle over a top of the foot so as to allow dorsiflexion of the foot; and (b) a firm posterior support means connected to the anterior support means to be mounted adjacent to and conform to a posterior portion of the ankle, the posterior support means having an arcuate sidewall between a proximal open end and a distal open end along and around the longitudinal axis of the leg, wherein the sidewalls define an opening extending between the distal open ends and the proximal open ends and wherein when mounted around the ankle, the anterior support means and the posterior support means together extend downward beyond the malleoli of the ankle and provide encompassing pressure around the circumference of the ankle and the foot. - View Dependent Claims (20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33)

34. A method for limiting inversion and eversion of an ankle and a foot and allowing dorsiflexion and plantar flexion of the ankle and the foot, which comprises:
-
(a) providing a custom fitted brace for limiting eversion and inversion of an ankle and a foot which comprises;
a firm anterior support means having a proximal end and a distal end with an arcuate sidewall therebetween to be mounted adjacent to and conform to an anterior portion of the ankle with the distal end of the anterior support means adjacent the foot and extending only slightly outward away from the ankle over a top of the foot so as to allow dorsiflexion of the foot; and
a firm posterior support means having a proximal end and a distal end with an arcuate sidewall therebetween connected to the anterior support means to be mounted adjacent to and conform to a posterior portion of the ankle with the distal end of the posterior support means adjacent the foot, wherein the anterior support means and the posterior support means together extend downward beyond the malleoli of the ankle and provide encompassing pressure around the ankle and the foot;(b) moving the anterior support means and the posterior support means of the brace apart; (c) inserting the foot into the brace adjacent the proximal end of the anterior support means and the proximal end of the posterior support means; (d) positioning the brace over the ankle such that the anterior support means is adjacent the anterior portion of the ankle and the posterior support means is adjacent the posterior portion of the ankle; (e) moving the anterior support means and the posterior support means together such as to encompass the ankle; and (f) securing the brace around the ankle such that the brace exerts encompassing pressure around the circumference of the ankle and the foot. - View Dependent Claims (35, 36, 37)
