Abstract

A removable ankle brace (10) comprises a rigid shoe (14), side members (16) extending upwardly from both sides of the rigid shoe and side plates (18) extending upwardly from the side members. The rigid shoe (14) comprises a molded plastic body portion (50). The side members (16) are formed integrally with the molded plastic body portion (50) thereby preventing relative motion therebetween. A brace for tibial fractures (110) is constructed similarly to the removable ankle brace, but includes an extension (112) secured to the side plates (18'"'"') and extending upwardly therefrom.

Claims

1. A brace for treatment of tibial fractures comprising:

a rigid shoe including a planar upper surface member for engaging the sole of the patient'"'"'s foot, side walls extending perpendicularly to the upper surface and downwardly therefrom, and an outer sole member comprising the lowermost surface of the shoe;

the outer sole of the shoe having a fulcrum, a planar first portion extending rearwardly from the fulcrum to the heel of the shoe and a second portion comprising a continuous curve extending from the fulcrum upwardly and forwardly to the toe of the shoe;

means for locating the foot of the patient on the planar upper surface of the shoe with the metatarsal point of the foot positioned forward of the fulcrum so that the shoe normally sets on the planar first portion of the outer sole and pivots about the fulcrum onto the curved second portion as the weight of the patient shifts forward of the metatarsal point of the foot;

said rigid shoe further comprising a molded plastic body portion having the planar upper surface member and the outer sole member secured thereto and molded plastic left and right side members formed integrally with the body portion and positioned on opposite sides of the shoe;

the side members each comprising a first portion extending from the side wall of the shoe angularly upwardly and outwardly with respect thereto and a second portion extending upwardly from the upper end of the second portion substantially parallel to the side wall of the shoe;

plastic side plates secured to the side members and each including an attachment portion secured to the second portion of its respective side member, a second portion extending from the upper end of the attachment portion angularly upwardly and inwardly with respect thereto, and a third portion extending upwardly from the upper end of the second portion generally parallel to the second portion of the side member and to the attachment portion of the side plate;

the third portion of each side plate positioned over the side wall of the shoe and being curved inwardly to conform to the calf of the patient;

each side member further including a layer of foam padding secured to the inside surface thereof and extending upwardly along the inner surfaces of the first and second portions of the side member;

an extension secured to the upper end of the third portion of the side plates and extending therefrom upwardly beyond the knee of the patient; and

fastening means for securing the shoe, the side members and the extension in place relative to the leg of the patient.

2. The brace according to claim 1 further including a foam cuff dimensioned to surround the portion of the leg of the patient extending above and below the knee and means mounted on the inner surfaces of the extension for securing the cuff thereto.

3. The brace according to claim 1 wherein the fastening means comprises:

first strap means for connection between aligned points on the side walls of the shoe adjacent the toe thereof;

second strap means for connection between points on the side walls and points on the opposite side members;

said first and second strap means for securing the shoe to the foot of the patient;

third strap means for connection between aligned points on the side plates to secure the side plates to the calf of the patient; and

fourth strap means for connection between aligned points on the extension to secure the extensions to the portion of the leg of the patient extending above and below the knee.

4. The brace according to claim 3 further including fasteners extending through the second portions of the side members and the attachment portions of the side plates for joining each side member, its corresponding side plate and the second strap means one to another.

5. The brace according to claim 1 further including plastic reinforcing members formed integrally with the body portion and the side members and extending along the inside surfaces of the side members from the lower ends of the second portions thereof to the body portion.

6. A removable ankle brace comprising:

a rigid shoe including a planar upper surface member for engaging the sole of the patient'"'"'s foot, side walls extending perpendicularly to the upper surface and downwardly therefrom, and an outer sole member comprising the lowermost surface of the shoe;

the outer sole of the shoe having a fulcrum, a planar first portion extending rearwardly from the fulcrum to the heel of the shoe and a second portion comprising a continuous curve extending from the fulcrum upwardly and forwardly to the toe of the shoe;

means for locating the foot of the patient on the planar upper surface of the shoe with the metatarsal point of the foot positioned forward of the fulcrum so that the shoe normally sets on the planar first portion of the outer sole and pivots about the fulcrum onto the curved second portion as the weight of the patient shifts forward of the metatarsal point of the foot;

said rigid shoe further comprising a molded plastic body portion having the planar upper surface member and the outer sole member secured thereto and molded plastic left and right side members formed integrally with the body portion and positioned on opposite sides of the shoe;

the side members each comprising a first portion extending from the side wall of the shoe angularly upwardly and outwardly with respect thereto and a second portion extending upwardly from the upper end of the second portion substantially parallel to the side wall of the shoe;

plastic side plates secured to the side members and each including an attachment portion secured to the second portion of its respective side member, a second portion extending from the upper end of the attachment portion angularly upwardly and inwardly with respect thereto, and a third portion extending upwardly from the upper end of the second portion generally parallel to the second portion of the side member and to the attachment portion of the side plate;

the third portion of each side plate being positioned over the side wall of the shoe and being curved inwardly to conform to the calf of the patient;

each side member further including a layer of foam padding secured to the inside surface thereof and extending upwardly along the inner surfaces of the first and second portions of the side member; and

fastening means for securing the shoe, the side members and the side plates in place relative to the leg of the patient.

7. The brace according to claim 6 further including a foam cuff dimensioned to surround the portion of the leg of the patient and means mounted on the inner surfaces of the side plates for securing the cuff thereto.

8. The brace according to claim 6 wherein the fastening means comprises:

first strap means for connection between aligned points on the side walls of the shoe adjacent the toe thereof;

second strap means for connection between points on the side walls and points on the opposite side members;

said first and second strap means for securing the shoe to the foot of the patient; and

third strap means for connection between aligned points on the side plates to secure the side plates to the calf of the patient.

9. The brace according to claim 8 further including fasteners extending through the second portions of the side members and the attachment portions of the side plates for joining each side member, its corresponding side plate and the second strap means one to another.

10. The brace according to claim 6 further including plastic reinforcing members formed integrally with the body portion and the side members and extending along the inside surfaces of the side members from the lower ends of the second portions thereof to the body portion.
