A composition for spinal disc repair comprising a plurality of uniformly shaped demineralized cancellous bone pieces ranging in size from about 2.0 mm to about 4.0 mm loaded into a porous mesh container with the cancellous bone pieces being treated so that they are not osteoinductive and are packed in the porous mesh container under compression forces.

A system and method for securing a target body to a bone mass with a loop-in-loop suture anchor. The system generally includes suture material passing through a substrate (e.g., suture anchor). The suture material includes a splice that allows the suture material to be passed through the splice and around a target body, ultimately creating three loops in the suture material. By tensioning the loops and / or ends of the suture material, the loops bring the target body into a desired position relative to the bone mass and secure it in that position.

The invention discloses a fracture rehabilitation evaluation method based on a six-axis parallel external bone fixation device, which mainly comprises the following steps: adding a sensor to each branch chain of a prior six-axis parallel external bone fixation device, and restoring and fixing the fracture using a modified device; using a marker, wherein the space positions and postures of the fracture bone blocks and external bone fixation device are identified through the medical CT scanning; dividing the rehabilitation process into a first time period and a second period according to a clinical general rehabilitation phase dividing method, wherein, when a patient is in the first time period, the mechanical condition of the fracture part is measured and analyzed, and the external bone fixation device is finely adjusted and the patient is guided to carry out rehabilitation training; when the patient is in the second time period, the quantitative index of the fracture recovery is calculated, and the external bone fixation device is removed at appropriate timing. The method is suitable for all kinds of commercially available six-axis parallel external bone fixation devices, and haseconomy and convenience; according to the method, the quantitative evaluation of fracture rehabilitation is carried out by using an energy analysis method, and the reliability is good.

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 a method of harvesting grafts that has improved efficiency and increases the quantity of extracted tissue and minimizes time required by surgeon for implantation.

The invention belongs to the technical field of medical device design, and in particular relates to a CR-type and PS-type femoral condyle trial mold and an intercondylar processor function integrated structure, including an intercondylar milling cutter, a femoral condyle trial mold, an intercondylar trial mold, an intercondylar Processor and intercondylar osteotome, the intercondylar joint surface of described femoral condyle trial mold is matched with the joint curved surface of intercondylar trial mold; Described intercondylar processor comprises insertion end and connecting end, and described insertion end can be inserted with it In the intercondylar processor connecting hole on the matching femoral condyle trial mold, the connecting end can be connected with the intercondylar milling cutter and the intercondylar bone knife. The invention has the advantages of replacing the optimal operation plan and supporting tools at any time; reducing the number and cost of tools; ensuring the accuracy of the installation position of the prosthesis, reducing the mutual matching of various parts during the operation; and realizing effective bone saving.
