Abstract: This invention provides a method for manufacture of autograft, allograft and xenograft implants which comprises assembling such implants from smaller pieces of graft materials to form a larger graft implant product.

Abstract: This invention provides a novel unitary bone implant having at least one rigid, mineralized bone segment, which may be machined to include threads, grooves, a driver head, a recess or a symmetric or asymmetric shape, and a flexible, demineralized segment, which may also be machined to any desired shape prior to demineralization, or after demineralization. The implant of this invention has wide orthopedic applicability, including for repair or replacement of ligaments, tendons and joints.

Abstract: Open chambered spacers, implanting tools and methods are provided. The spacers 500' include a body 505' having a wall 506' which defines a chamber 530' and an opening 531' in communication with the chamber 530'. In one embodiment the wall 506' includes a pair of arms 520', 521' facing one another and forming a mouth 525' to the chamber 530'. Preferably, one of the arms 520' is truncated relative to the other, forming a channel 526. In one aspect the body 505' is a bone dowel comprising an off-center plug from the diaphysis of a long bone. The tools 800 include spacer engaging means for engaging a spacer and occlusion means for blocking an opening defined in the spacer. In some embodiments, the occlusion means 820 includes a plate 821 extendable from the housing 805. In one specific embodiment the plate 821 defines a groove 822 which is disposed around a fastener 830 attached to the housing 805 so that the plate 821 is slideable relative to the housing 805.
