Atraumatic fasteners involving flexible membranes and tensioning means can be used in conjunction with one or more plates, other fastener types of other materials, particularly locked cannulated screws-plate interfaces providing improved capture and restraint of articular and/or juxta-articular bone fragments. A method of securing bone fragments includes securing or capturing a fragment, at least in part, with an atraumatic foldable and/or expandable device which can be inserted “inside out”, that is, the expandable form is inserted through a channel which has been created in the bone or tissue, from the opposite side of the bone or tissue fragment.
