A bone fastener for stabilizing bone fragments includes a single or multiple components coupleable with one another and displaceable to a locked position of the bone fastener.

Bone fasteners and method for stabilizing vertebral bone facets using the bone fasteners

A C-shaped or ring shaped implant formed of cortical bone has its C-shaped or inner channel filled with a bone promoting material which is preferably demineralized bone fibers formed as a flexible wet sheet or may be cancellous bone, pressed bone fibers formed from demineralized cortical bone chips soaked in acid, or a flex material formed of demineralized bone growth promoting bone fibers. The discrete bone filler element may be secured by a bonding agent, pins or screws, metal, polymer or bone material. The bone filler material is preferably bonded by filling a section of a long bone medullary cavity with wet bone fibers and then drying the fibers to bond them to the outer bone. A filled bone ring may be sliced to form annular filled sections which are then divided into mirror image C-shaped halves each forming an implant. Flex material of compressed bone fibers may be formed with an opening shaped to receive a cortical bone implant element having a C-shaped channel. The flex material surrounds the cortical bone element and fills its channel. Other embodiments are disclosed.
