Abstract

A rigid cast which is useful for immobilizing injured body parts, which is essentially removable and subsequently replaceable after removing same, comprising a rigid structure of two or more integral components, which at least partially surround said injured body parts, consisting of: (1) at least one material, which is shaped to conform to the contour of said body parts; and (2) at least one cooperating fastener means which is effective in securing said material allowing the resultant components to achieve said immobilization of said body parts.

Claims

1. A rigid cast which is useful for immobilizing an injured body part, which is readily removable and subsequently replaceable after removal by a user, comprising:

two rigid body part immobilizing parts adapted to surround and conform exactly to an injured body part, said rigid body part immobilizing parts having been custom formed by applying a casting medium to said body part so that said casting medium conforms exactly to said body part, allowing said casting medium to harden on said body part to form a unitary rigid supporting shell, making two longitudinal cuts in said unitary rigid supporting shell to form said two rigid body part immobilizing parts which each have opposing and cooperating cut faces along each of said two cuts and integrally attaching a plurality of cooperating releasable fastener means to each of said rigid body part immobilizing parts on opposite sides of at least one of said longitudinal cuts for releasably and replaceably securing said rigid body part immobilizing parts along said cooperating cut faces, said cooperating releasable fastener means being capable of mechanically compressing said two rigid body part immobilizing parts onto said injured body part; and

at least one soft inner material located on the interior of said cast which is shaped to conform exactly to the contour of said body parts thereby allowing said rigid body part immobilizing parts to achieve immobilization and compression of said body part.

2. The rigid cast of claim 1, wherein comprises a plurality of said fastener means along said at least one of said longitudinal cuts and hinge means provided along the other of said longitudinal cuts.

3. The rigid cast of claim 1, wherein said fastener means is adjustable and can be preset for a desired degree of compression.

4. The rigid cast of claim 1, wherein said cooperating releasable fastener means comprises loop means attached to one of said rigid body part immobilizing parts adjacent to said at least one of said longitudinal cuts for providing an opening and projection means attached to said other rigid body part immobilizing part for insertion into said opening, wherein said loop means and said projection means cooperate to effectuate said compression.

5. The rigid cast of claim 4, wherein said fastener means further comprises a lever for effectuating said compression.

6. The rigid cast of claim 1, which is adapted to conform to a lower leg and ankle of said user.

7. The rigid cast of claim 1, which is made out of fiberglass.

8. The rigid cast of claim 1, which is made out of plaster of paris.

9. A method of custom forming a rigid cast which is useful for immobilizing an injured body part, which is readily removable and subsequently replaceable after removal by a user comprising the steps of:

applying at least one soft inner material onto said injured body part to conform exactly to the contour of said injured body part;

applying a casting medium to said body part so that said casting medium conforms exactly to said body part, allowing said casting medium to harden on said body part to form a unitary rigid supporting shell;

making two longitudinal cuts in said unitary supporting shell to form two rigid body part immobilizing parts which each have opposing and cooperating cut faces along each of said two cuts; and

integrally attaching a plurality of cooperating releasable fastener means to each of said rigid body part immobilizing parts on opposite sides of at least one of said longitudinal cuts for releasably and replaceably securing said rigid body part immobilizing parts along said cooperating cut faces, said releasable fastener means being capable of mechanically compressing said two rigid body part immobilizing parts onto said injured body part.
