Abstract
Abstract An anterior total contact hyperextension orthosis apparatus method of making a hyperextension orthosis. A stockinette is placed on a patient's body and marked for pre-determined patient features. A cast is formed on the patient's body for making a drape mold. The stockinette markings transfer to the cast and to the mold. The mold is modified including conforming the mold to the measured patient's breast portion and breast position, and the orthosis body is drape formed on the mold. The orthosis body is a molded plastic material having a breast support portion formed to be supported on the patient's breast, along with a pubic support portion and a center support portion formed between the breast support portion and the pubic support portion to conform to the patient's body therebetween to apply pressure primarily to soft tissue. Straps are attached to the anterior body portion and to a lumber pad for attaching the brace to the patient.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
164 words
A method of making an anterior total contact hyperextension orthosis which utilizes contact with a patient's breasts as a supporting surface comprising the steps of: placing a stockinette on a patient; marking the stockinette with a transferrable dye to mark the position of the patient's breasts; measuring the patient's breast for size in a standing or sitting position; forming a cast on a patient's body over said stockinette with the patient being in a supine position; removing the cast and forming a mold therein having the dye markings thereon transferred from the marking made on said stockinette for said patient's breast position; mounting the mold onto a stand; modifying the mold to conform to a patient, including mounting breast cup molded parts to conform to the measured patient's breast in a standing or sitting position on the dye marked portion of said mold; and drape forming an anterior hyperextension orthosis on the mold formed to apply a uniform support pressure on the patient's breasts.
