Two piece cancellous construct for cartilage repair |
摘要 |
The invention is directed toward a cartilage repair assembly comprising a shaped allograft two piece construct with a demineralized cancellous cap and a mineralized cylindrical base member defining a blind bore with a through going transverse bore intersecting the blind bore. The demineralized cancellous cap has a cylindrical top portion and a smaller diameter cylindrical stem extending away from the top portion which fits into the blind bore of the mineralized base member. The cap stem defines a transverse through going bore which is aligned with the through going bore of the base member to receive a cylindrical cortical pin holding the cap within the base member. The shaped structure is dimensioned to fit in a drilled bore in a cartilage defect area so that the assembly engages the side wall of the drilled bore in an interference fit. |
