INTERMEDIATE BONE BLOCK AND ITS USE IN BONE BLOCK ASSEMBLIES AND ASSEMBLED BONE-TENDON-BONE GRAFTS

摘要

The present invention is directed to an intermediate bone block comprising a machined segment of cortical bones, cancellous bone or both, the intermediate having a face comprising one to two compression surfaces and one to ten cavities, the compression surfaces suitable for compressing soft tissue, the cavities for receiving and holding overflow soft tissue. The cavities are preferably channels, and more preferably channels having an omega cross-sectional profile. The cavities and channels significantly improve tendon load at failure. The invention is also directed to bone block assemblies suitable for binding to a soft tissue to form an implantable graft, and to such implantable grafts. A particular preferred graft is a bone-tendon-bone graft.
