Rollable bone implant for enclosing bone material

A kit for making a bone implant, the kit comprising a covering, the covering comprising a body portion and a closure portion adjacent to the body portion, the body portion comprising a surface and a first edge opposing a second edge across a longitudinal axis of the body portion, the first edge and the second edge configured to overlap on the surface to enclose the bone material in the body portion, the closure portion comprising a plurality of mesh threads, and a first edge opposing a second edge, the plurality of mesh threads disposed between the first edge of the closure portion and the second edge of the closure portion, the first edge of the closure portion joining the first edge of the body portion, wherein the kit further comprises a sizing ring configured to be disposed around the second cylindrical body such that the sizing ring determines a diameter of the covering and is configured to hold the covering in a rolled configuration to a predetermined diameter, wherein the body portion comprises threads having a narrower regular pattern and the closure portion comprises threads having a wider regular pattern relative to the body portion such that the closure portion is more flexible than the body portion and more deformable than the body portion to wrap around and hold the body portion in the rolled configuration, wherein the body portion forms two opposing open ends at the first edge and the second edge configured to be pulled to have smaller diameters than a diameter formed by the surface in the rolled configuration, the rolled configuration being in a tubular conformation, and wherein the narrower regular pattern is a different pattern relative to the wider regular pattern such that the wider regular pattern has a larger porosity than a porosity of the narrower regular pattern allowing the bone material to be disposed in the body portion when the closure portion wraps around the body portion.
