摘要：
The present invention has multiple aspects. In its simplest aspect, thepresent invention is directed to an intermediate bone block comprising amachined segment of cortical bone, cancellous bone or both, the intermediatehaving a face comprising one to ten compression surfaces and one to tencavities, the compression surfaces suitable for compressing soft tissue, thecavities for receiving and holding overflow soft tissue. The cavities arepreferably channels, and more preferably channels having an omega cross-sectional profile. Surprisingly, the cavities and channels, which reduced thecompressed surface area between the intermediate bone block and the tendon,significantly improved tendon load at failure. In standardized tests, anintermediate bone block of this invention, when combined with high surfacearea bone blocks of the prior art bone blocks, unexpectedly increased theirload at failure. The invention is also directed to bone block assembliessuitable for binding to a soft tissue to form an implantable graft, and tosuch implantable grafts. A particularly preferred graft is a bone-tendon-bonegraft.
