Abstract
Systems and methods here include a meniscal allograft with a bone block and a technique for making a desired shape in the bone block to be used to implant in a patient. A clamp and/or jig arrangement are disclosed that are able to secure the tissue and allow three corresponding cuts to the tissue using the clamp as a guide to a saw to obtain the desired shape.
Claims19
A method for preparing a meniscal tissue for implant, comprising:
- mounting a bone block with meniscal tissue in a clamp once, wherein the clamp comprises a first clamp side and a second clamp side, wherein the first clamp side and the second clamp side each comprise three outside guide edges;
- and
- sawing the bone block with meniscal tissue in each of three positions along the three outside guide edges of the first clamp side and second clamp side without removing or adjusting the clamp, to obtain a shape that is generally a shape of the three outside guide edges of the first clamp side and second clamp side.
A system for preparing a meniscal tissue for implant, comprising:
- a clamp with a first clamp side and a second clamp side, a base connecting the first clamp side and the second clamp side, wherein the first clamp side and second clamp side each include at least three shaped edges;
- wherein the first clamp side and the second clamp side each include an outer frame and an inner tongue both mounted on the base on their respective sides, wherein each tongue is configured to be able to flex under pressure, and wherein the first clamp side includes a friction component and wherein the second clamp side includes a set screw, wherein the clamp is configured to guide sawing a bone block secured in the clamp along each of the three shaped edges without removing or adjusting the clamp to obtain a shape that is generally of a same shape as the first clamp side and the second clamp side three edges.
A system comprising a slot cut jig made of metal having a top, bottom, two sides, and a middle bone block slot shaped in a general trapezoid, a top saw slot in the top, a bottom saw slot in the bottom, wherein the top saw slot and bottom saw slot align with one another and run through the middle bone block slot;
- wherein the slot cut jig being shaped to allow a shaped bone block and meniscus to be inserted in the middle bone block slot, wherein the slot cut jig is configured to protect the shaped bone block and meniscus for transportation and handling when inserted in the middle bone block slot, and wherein the top saw slot and bottom saw slot are configured to allow preparation of the bone block by sawing through the aligned top saw slot and the bottom saw slot and thereby the middle bone block slot to remove a triangular piece of the bone block.
