Aurora Spine, a US-based orthopaedic implant company said that first surgery using its Zip Graft pre-packaged sterile bone dowel was carried out at the Madison County Hospital in London, Ohio.

Aurora Spine East sales vice president Doug Johnson said: "We are very excited to see the Zip Graft used in conjunction with the Zip MIS fusion device.

"The allograft bone dowels are designed and sized to fit into our devices thus creating an integrated fit every time."

Zip Graft is a cancellous allograft designed specifically to fit into the Zip MIS interspinous fusion system. The bone dowel, which is gamma irradiated and packaged sterile for immediate use, is available in various sizes.

The company said that ZIP Graft, which is originally released in Europe as a pre-packaged sterile synthetic bone dowel composed of tri-calcium phosphate, will also be continuously commercialized throughout Europe.
