Methods of arthroscopic harvesting of bone marrow aspirate from bone joints and therapeutic application of the bone marrow aspirate in a bone joint. The method of harvesting includes extracting bone marrow from a joint, adding a biomaterial, and adding clotting agent to form a clot.

A bone joint repair and replacement assembly. A first portion comprising a bone plate is configured to attach to a distal or proximal end of a bone proximate the joint, generally coaxially with an axis defined by the bone. A second portion comprising an articular surface is configured to attach to the first portion, generally normal with respect to the axis, and inserted into the joint. Although versions of the assembly can be configured for use with several different pivotal joints, the invention is particularly suitable for full or partial replacement of an elbow, wherein the articular surface is pivotally attached to the first portion. Another embodiment of the invention is provided to repair a fractured bone head proximate the joint, and still another embodiment of the invention is provided to repair rotator cuff-related shoulder injuries.

A method of repairing a bone joint by using a simple and flexible artificial ligament which easily conforms to a patient's anatomy and can be used independently or in combination with an intervertebral graft, implant or prosthesis to return stability to the spine subsequent to a surgical spine procedure, is disclosed. The method includes anchoring the artificial ligament to at least two vertebrae to aid in restoring stability to the compromised joint. The artificial ligament is also disclosed.

The present invention concerns the field of orthopaedic surgery, veterinary surgery, and maxillofacial surgery. The invention may find application in other fields such as dentistry or where joining, fusing or stabilising of two bones (or one bone and one prosthetic member) are required. There invention provides a surgical bone tie for use in joining abutting bone surfaces for fusing or knitting of the bone together, the tie comprising (or consisting of) first and second pieces each having a proximal end region and a distal end region which define a longitudinal axis therebetween, wherein the distal end regions are each provided with a mounting feature for fixing, or permitting the fixing, of each piece to respective underlying portions of bone, wherein the proximal end regions of each pieces are adapted for engagement together along said axis so that one proximal end region may be accommodated by the other proximal end region to provide a bridge between the respective distal end regions, the engagement permitting one way travel of one piece progressively towards the other so that the bridge length becomes progressively smaller until a desired amount of separation between the distal end regions is obtained, and the a desired compression between the abutting bones is obtained. The engagement between the proximal end regions preferably comprises a ratchet and pawl connection.

In a first broad aspect, there is provided herein a bioactive device and system for fusion between two bones, two parts of a bony joint, or a bony defect, such as of the spine. The fusion device includes a screw having a head and a threaded shaft. The fusion device also includes a bone dowel having an internal bore of which at least a distal portion is threaded to engage the threads of the screw shaft. The bone dowel is made of a bone-like, biocompatible, or allograft material to provide a layer of bone-like, biocompatible, or allograft material between the screw and the spinal bone. The device is generally coaxial and is further described in the drawings and description herein.

Disclosed is a bone fixation device of the type useful for connecting two or more bones or bone fragments together or connecting soft tissue or tendon to bone. The device comprises an elongate body having a distal anchor thereon. An axially moveable proximal anchor is carried by the proximal end of the fixation device, to accommodate different bone dimensions and permit appropriate tensioning of the fixation device. A sleeve can surround at least a portion of the bone fixation device to promote bone in-growth with or at the bone joint or fracture to facilitate fusion of the bone segment.

The invention discloses a high-shape-adaptability bionic cooperation joint between shin bone and ankle bone. The upper part of the cooperation joint (1) is a shin bone cooperation surface (2) cooperating with a shin bone joint surface, the lower part of the cooperation joint is an ankle bone cooperation surface cooperating with an ankle bone joint surface, the shin bone cooperation surface (2) isa concave globular arc surface designed through imitating human body biomechanics, and a lower convex V-shaped fin (4) cooperating with the ankle bone joint surface is arranged on the ankle bone cooperation surface (3). The high-shape-adaptability bionic cooperation joint between shin bone and ankle bone is designed based on the human body biomechanics principle, so that the whole and the cooperation surfaces of the bionic cooperation joint conform to the characteristics of an original bone structure; and besides, the situations that the cooperation of the bionic cooperation joint with the shin bone, the ankle bone or replacement components is proper, sliding is smooth and round, and the stability is better are guaranteed, so that long-term stable work of the bionic cooperation joint afterreplacement is maintained, and pain of a surgery recipient is reduced. The high-shape-adaptability bionic cooperation joint between shin bone and ankle bone disclosed by the invention is convenient in clinical use, and is convenient to popularize and apply, the postoperative functions of the patient is well restored, and the safe use period is greatly prolonged.

The invention relates to an improved artificial knee joint tibial tray which is characterized in that the improved artificial knee joint tibial tray is cast or forged, and then a porous medical metal film is formed on the corresponding surface, being in contact with a bone of a patient, of the tibial tray through the additive manufacturing. The strength and mechanical properties of the tibial tray are guaranteed by casting and forging, and then the optimal porosity is customized for the porous film through the additive manufacturing, so that bone attachment or bone ingrowth can be facilitated to the maximum. The improved artificial knee joint tibial tray is suitable for a bone joint replacement surgery for human knee joint lesions.

The invention relates to an improved artificial hip joint femoral stem which is characterized in that the improved artificial hip joint femoral stem is cast or forged, and then a rough medical metal film is formed on the corresponding surface, being in contact with a bone of a patient, of the femoral stem through additive manufacturing. The strength and mechanical properties of the femoral stem are guaranteed by casting and forging, and then the optimal roughness is customized for the rough film through the additive manufacturing, so that bone attachment or bone ingrowth can be facilitated to the maximum. The improved artificial hip joint femoral stem is suitable for a bone joint replacement surgery for human hip joint lesions.
