Orthopedic rigid splint-plate orthosis

Abstract

An orthopedic rigid splint-plate orthosis comprises a splint-plate which is provided in one of a combination of different shapes and sizes corresponding to different body members which may have to be treated. The splint-plate has at one of its edges a non-stretchable linking ribbon which at the end thereof opposite to the end joined to the plate includes locking means which are complementary with corresponding locking means provided in the edge of the plate opposite to that edge joined with the ribbon. The plate is provided presterilized and isolated inside an impervious bag which may be filled with boiling water to make the rigid splint-plate soft, whereafter the water is drained and the softened plate applied and moulded to the body member and then left to harden back to its rigid state. For use in an operating theatre, the bag with the plate may be closed inside a second bag and sterilized with gas or radiation; thereafter, the plate may be softened by submerging the sealed outside bag in hot water.

I claim: 
     
       1. A method for immobilizing an injured body member comprising: (a) opening .[.the.]. .Iadd.a .Iaddend.bag in a combination comprising a splint-plate .Iadd.and the bag, with the splint plate .Iaddend.inside .[.a water.]. .Iadd.the bag, the bag being liquid .Iaddend.impervious.Iadd., .Iaddend.aseptically closed .[.bag.]., mechanically resistant to the weight of the splint-plate and thermally resistant to temperatures at or below the boiling point of water, the splint-plate comprising a rigid thermoplastic plate pre-cut to conform to a specific body member .[.and provided with fastening means attached thereon.].;   (b) pouring a liquid into the opened bag, the liquid being at a temperature at or below the boiling point of water and above the softening point of the thermoplastic splint plate;   (c) allowing the splint-plate to remain in the liquid until the splint-plate softens;   (d) removing the softened splint-plate from the bag;   (e) applying the softened splint-plate to a body member and molding it to fit the body member; and   (f) securing the splint-plate in place around the body member .[.with the fastening means.]..   
     
     
       2. The method according to claim 1.Iadd., .Iaddend.wherein the softened splint-plate is removed from the bag by cutting the bottom of the bag to allow the liquid to drain from the bag. 
     
     
       3. The method according to claim 1.Iadd., .Iaddend.wherein the splint-plate is secured in place using at least one non-stretchable linking strip, one end of the strip being connected to the splint-plate and the other end of the strip being provided with a locking means which is engageable with a complementary locking means attached to the splint-plate. .Iadd. 
     
     
       4.  The method according to claim 1, wherein the step of securing comprises securing the splint-plate in place around the body member with a fastening means attached to the splint-plate. .Iaddend. .Iadd.5. A combination for immobilizing an injured body member comprising an orthopedic splint-plate, a liquid-impervious, aseptically closed bag holding the splint-plate, the bag being mechanically resistant to the weight of the splint-plate and thermally resistant to temperatures at or below the boiling point of water, said bag being provided for receiving a hot liquid therein at or below the boiling point of water thereby to soften the splint-plate, the splint-plate comprising a rigid thermoplastic plate pre-cut to conform to a specific body member, the thermoplastic plate being deformable to conform to the body member after heating to a temperature at or below the boiling point of water, and becoming rigid on the body member upon subsequent cooling, said splint-plate further comprising a plurality of holes therethrough which permit the circulation of air from one face of the splint-plate to its other face. .Iaddend. .Iadd.6. The combination according to claim 5, further comprising fastening means attached to the thermoplastic plate for securing the plate to the body member. .Iaddend. .Iadd.7. The combination according to claim 5, wherein the bag has a V-shaped bottom part which can easily be cut to discharge the contents of the bag. .Iaddend. .Iadd.8. The combination according to claim 6, wherein the fastening means comprises at least one non-stretchable locking strip, one end of the strip being provided with a locking means which is engageable with a complementary locking means attached to the splint-plate. .Iaddend. .Iadd.9. The combination according to claim 5, wherein the splint-plate has a face intended to contact the body member 
     
     
        comprising padding. .Iaddend. .Iadd.10.  A combination for immobilizing an injured body member comprising an orthopedic splint-plate, a liquid-impervious, aseptically closed first bag holding the splint-plate, the bag being mechanically resistant to the weight of the splint-plate and thermally resistant to temperatures at or below the boiling point of water, the splint-plate comprising a rigid thermoplastic plate pre-cut to conform to a body member and being deformable to conform to the body member after being heated in the bag to a temperature at or below the boiling point of water and becoming rigid on the body member upon subsequent cooling, and further comprising a second bag disposed about and sealing the first bag so that the second bag containing the first bag with the splint-plate may be submerged in a hot liquid to soften the splint-plate without contact of the hot liquid with said first bag and splint plate, said bags being permeable to sterilizing gas for sterilizing the splint-plate, but impermeable to the hot liquid and to microbes. 
     
     
        .Iaddend. .Iadd.11.  A combination for immobilizing an injured body member comprising an orthopedic splint-plate, a liquid-impervious, aseptically closed bag holding the splint-plate, the bag being mechanically resistant to the weight of the splint-plate and thermally resistant to temperatures at or below the boiling point of water, the splint-plate comprising a rigid thermoplastic plate pre-cut to conform to a body member, the thermoplastic plate being deformable to conform to the body member after being heated in the bag to a temperature at or below the boiling point of water and becoming rigid on the body member upon subsequent cooling, said bag being permeable to sterilizing gas for sterilizing the splint-plate, but impermeable to hot liquid and to microbes. .Iaddend.
