A bone graft containment device includes a body formed via one or more helical structures extending about a longitudinal axis of the body from a first end to a second end to define a channel extending longitudinally therethrough. The channel is configured to receive a bone graft or bone graft substitute material therein, the one or more helical structures formed of a material permitting the body to be one of expanded, compressed and curved to fill a target space of a target bone.

The invention concerns a bone graft material for use in a spinal fusion method, wherein the material comprises i) a composition for forming a matrix, comprising at least a first matrix material precursor component and a second matrix material precursor component, capable of forming a matrix by crosslinking of the precursor components under appropriate conditions; and ii) a bioactive factor, which is biologically active to stimulate bone formation between two vertebrae, and for effecting or supporting spinal fusion; wherein the spinal fusion method comprises the steps of applying a cage in between the two vertebrae, which is not pre-filled with the bone graft material; and subsequently applying the bone graft material adjacent to and/or into the cage, such that essentially the entire remaining volume between the two vertebrae is filled with the bone graft material. The invention allows for ease of use while forming a more homogeneous matrix.

The present invention relates to bone-implants for treating a lesion on a bone, comprising: a bone anchor, a container in communication with the bone anchor and an osteoconductive bone-filler material inside the container, and methods thereof.

A component of an artificial joint according to an exemplary aspect of the present disclosure includes, inter alia, a hollow tube including bone ingrowth material. Further, the hollow tube is selectively expandable. The bone ingrowth material allows the component to become biologically fixed to adjacent bone. Further, expansion of the hollow tube increases friction between the hollow tube and the adjacent bone, which increases stability.

A filament or printing material placed in a syringe for 3D printing comprising polymers, proteins, and/or functional particles and materials is provided. Methods of treating a bone defect in a subject in need thereof comprising using a handheld 3D printer to apply a filament or the printing material placed in a syringe to the bone defect of the subject are also provided. Methods of fixing or gluing natural or synthetic bone grafts using a handheld 3D printer to apply a filament or the printing material placed in a syringe over and around the defect or at the interface of a flap and the bone. Methods of printing a graft cage for retaining bone grafts and/or bone graft substitute in its desired location during healing for treatment of critical-sized segmental defects in long bones are provided.

The method of treating osteoarthritis of the knee (OAK) includes resection of the patella, patellar tendon, proximal tibia, and distal femur, and bone grafting after resection. The bone grafting includes using a single complete osteo-articular allograft configured to replace the knee joint, distal femur, and proximal tibia. Metallic plates are used for internal fixation of the allograft. The procedure can provide patients with full knee flexion, and thereby enable kneeling, e.g., as required in the Islamic prayer.

A tibial implant may include a plurality of geometrically conformal implant subunits. The implant subunits may be configured for individual insertion within a wedge-shaped-void of the tibia. The implant subunits may further be configured for assembly in order to provide an implant substantially covering an exposed portion of cortical bone formed when performing a surgical osteotomy. In some embodiments, some or all of the plurality of subunits may be mechanically interlocked with each other. Methods and kits for insertion and assembly of implants are further described.

A knotless tensionable fixation system may be utilized for performing surgical methods for repairing tissue defects within a joint. An exemplary surgical method may include fixating a graft over top of the tissue defect with the knotless tensionable knotless fixation system. The knotless tensionable fixation system may include a plurality of knotless suture anchors, the graft, and a reinforcement construct. The reinforcement construct may establish a fixed segment of material over the graft after being secured in place by the plurality of knotless suture anchors.

A process for manufacturing a cap (4) which has at least one nominal breaking point (16) of a covering device for a bone defect site (2) and a device (1) for covering and/or reconstructing a bone defect site (2) are proposed, wherein through comparing a first data set which represents the affected bone defect site (2) in the actual condition with a second data set which represents the nominal condition of a regenerated bone at the bone defect site (2), wherein the second data set has been calculated or recorded at a time at which the bone at the site now to be regenerated was still a healthy bone (18) it is made possible that the regenerated bone produced through the regeneration of the bone defect point (2) has a shape which corresponds to the shape the bone had at the site to be regenerated when it was still healthy.

A component of an artificial joint according to an exemplary aspect of the present disclosure includes, inter alia, a hollow tube including bone ingrowth material. Further, the hollow tube is selectively expandable. The bone ingrowth material allows the component to become biologically fixed to adjacent bone. Further, expansion of the hollow tube increases friction between the hollow tube and the adjacent bone, which increases stability.
