Claims3
The method of providing an anatomic support which comprises the steps of:
- fashioning an elastic fabric belt arrangement with a pocket closed on three sides and having an open, selectively closable mouth;
- charging a selected quantity of viscously fluid, flowable, permanently hardenable, polymeric brace material into said pouch;
- closing the mouth of said pouch;
- immediately stretching and snugly strapping said belt arrangement around a patient's body region to be supported, tensile forces generated in said belt arrangement, as a result of stretching it, acting to cause said brace material to flow, while in its unhardened state, into intimate conformity with the confronting, patient's body region;
- and allowing said brace material to harden in continuation of the application of said tensile forces whereby to form a permanently individually contoured splint shape.
