Disclosed herein is an improved Bone Tendon Bone graft for use in orthopedic surgical procedures. Specifically exemplified herein is a Bone Tendon Bone graft comprising one or more bone blocks having a groove cut into the surface thereof, wherein said groove is sufficient to accommodate a fixation screw. Also disclosed is a method of harvesting grafts that has improved efficiency and increases the quantity of extracted tissue and minimizes time required by surgeon for implantation.

Materials and methods for improved bone tendon bone transplantation

This invention is directed to an assembled implant comprising two or more portions of bone that are held together in appropriate juxtaposition with one or more biocompatible pins to form a graft unit. Preferably, the pins are cortical bone pins. Typically, the cortical pins are press-fitted into appropriately sized holes in the bone portions to achieve an interference fit. The bone portions are allograft or xenograft.

Assembled implant

An implant composed substantially of cortical bone is provided for use in cervical Smith-Robinson vertebral fusion procedures. The implant is derived from allograft or autograft cortical bone sources, is machined to form a symmetrically or asymmetrically shaped (e.g. a substantially 'D'-shaped) implant having a canal running therethrough according to methods of this invention, and inserted into the space between adjacent cervical vertebrae to provide support and induce fusion of the adjacent vertebrae. Osteogenic, osteoinductive or osteoconductive materials may be packed into the canal of the implant to expedite vertebral fusion and to allow autologous bony ingrowth.

Multi-component cortical bone assembled implant

Disclosed herein is an improved Bone Tendon Bone graft for use in orthopedic surgical procedures. Specifically exemplified herein is a Bone Tendon Bone graft comprising one or more bone blocks having a groove cut into the surface thereof, wherein said groove is sufficient to accommodate a fixation screw. Also disclosed is a porcine bone tendon bone graft for use in orthopedic procedures. Also disclosed are multiple embodiments of assembled bone tendon bone blocks for use in orthopedic surgeries. Additionally, a method of harvesting grafts that has improved efficiency, increases the quantity of extracted tissue and minimizes time required by surgeon for implantation is disclosed.

Open chambered spacers, implanting tools and methods are provided. The spacersinclude a bodyhaving a wallwhich defines a chamberand an openingin communication with the chamber. In one embodiment the wallincludes a pair of armsfacing one another and forming a mouthto the chamber. Preferably, one of the armsis truncated relative to the other, forming a channel. In one aspect the bodydoes a bone dowel comprise an off-center plug from the diathesis of a long bone. The toolsinclude spacer engaging means for engaging a spacer and occlusion means for blocking an opening defined in the spacer. In some embodiments, the occlusion meansincludes a plateextendable from the housing. In one specific embodiment the platedefines a groovewhich is disposed around a fastenerattached to the housingso that the plateis sliceable relative to the housing

Disclosed herein are biomedical implants, and methods of using same, that are derived from bone. Particularly exemplified are implants having a tapered dowel shape that are useful for implantation in the spine, and especially in the cervical region of the spine. The taper of the implants disclosed herein provides an advantage over conventional implants, as it creates the proper support and angulation to maintain the proper curvature of the spine. Optionally, the implants taught herein are associated with osteogenic materials or other biomedical substances.
