1. A method for producing a plasticized, load-bearing, bone graft, comprising:
- incubating a cleaned, non-demineralized, load-bearing, bone graft with one or more plasticizer compositions comprising one or more plasticizers and one or more biocompatible solvents without altering orientation of collagen fibers.

Abstract
The invention provides a plasticized bone and/or soft tissue product that does not require special conditions of storage, for example refrigeration or freezing, exhibits materials properties that approximate those properties present in natural tissue, is not brittle, does not necessitate rehydration prior to clinical implantation and is not a potential source for disease transmission. Replacement of the chemical plasticizers by water prior to implantation is not required and thus, the plasticized bone or soft tissue product can be placed directly into an implant site without significant preparation in the operating room.
