Abstract
The present invention provides biocompatible, non-resorbable porous containment structures for containment of bone graft material at a desired location for stimulation of bone growth. The porous containment structures have interconnected pores sized to allow fibrovascular integration with surrounding tissue and conduction of vascular tissue through the structure into the bone graft material.
Claims21
A method of facilitating growth of bone at a desired location comprising:
- shaping, by bending, a biocompatible, non-resorbable porous material comprising a porous matrix of interconnected pores into a shaped porous material for placement into the desired location, the shaped porous material comprising a base portion, a side portion, and a top portion, the side portion sharing a first shaped edge with the base portion to define an interior region of the shaped porous material, the top portion being hingedly attached to a second shaped edge of the side portion such that the top portion forms open and closed positions with the side portion, the top portion providing an opening into the interior region in the open position;
- placing a bone graft material inside the interior region of the shaped porous material;
- placing the top portion in the closed position by bending the top portion relative to the side portion at the second shaped edge to cover the placed bone graft material;
- stably fixing the shaped porous material containing the bone graft material to structures adjacent to the desired location;
- and
- permitting bone to grow in the desired location.
