An expandable spacer, comprising: an axial tube having a surface, a proximal end and a distal end and a length, wherein, said surface defines a plurality of slits, said plurality of slits defining at least two axially displaced extensions, such that when said tube is axially compressed, said extensions extend out of said surface and define a geometry of an expanded spacer. Preferably the spacer is adapted to be inserted between two spinal vertebrae of a human.

A procedure for harvesting graft material for use during bone fusion surgery. A generally U-shaped cutting blade is inserted to a certain position inside a defined space between adjacent bones to be fused, and the cutting blade is rotated so that it cuts into the adjacent bones and forms a solid bone segment within each one of the bones. Each bone segment is displaced so that a first end portion of the segment enters the bone opposite the bone within which the segment was formed, an intermediate portion of the segment spans the space between the bones, and a second end portion of the segment remains in the bone within which the segment was formed. Each bone segment thereby acts as a strut graft for promoting a fusion of the adjacent bones to one another.

An apparatus and a method are provided for performing cartilage graft implant surgeries. The apparatus comprises a graft plug kit comprising one or more grafts configured to treat osteochondral defects in various bone joint locations in a patient's body. Each of the grafts comprises a cartilage layer coupled with a bone portion. The cartilage layer comprises a thickness selected to closely match the thickness of existing cartilage at an implant location. The bone portion comprises surface features configured to encourage the patient's bone tissue to grow into the bone portion, thereby accelerating incorporation of the graft into the patient's bone. An instrument kit comprises a multiplicity of instruments configured for implantation of the grafts into the patient's body, including at least a graft inserter, a guidewire, a reamer, and a size gauge.

The present invention is directed to a fiber, preferably bone fiber, having a textured surface, which acts as an effective binding substrate for bone-forming cells and for the induction or promotion of new bone growth by bone-forming cells, which bind to the fiber. Methods of using the bone fibers to induce or promote new bone growth and bone material compositions comprising the bone fibers are also described. The invention further relates to a substrate cutter device and cutter, which are effective in producing substrate fibers, such as bone fibers.

The invention relates to an instrument and a corresponding surgical method for the removal of a bone insert, for example for a shoulder prosthesis. The instrument is of the type comprising: a stem-like body (40) extending along a longitudinal axis (x-x) and provided with a proximal grip and a distal operating head (15) slidably associated with the stem-like body (40) for movement towards and away from each other; a cutting element (30) inside said operating head; and an end tip (16) protruding coaxially from said operating head. The following is also provided: a pushing mechanism (8), inserted inside said operating head and acting on said cutting element so as to displace it angularly from a rest position, where it is concealingly housed inside said end tip, to an operative position where it projects through a side opening in the end tip; said cutting element having an end extending substantially in a direction transverse to said longitudinal axis when in the operative position.

A biocompatible construction adapted for use in joint surgeries. Among other things, the joint implant has an anterior cutting edge and a rotatable cutter distinct from the cutting edge. The rotatable cutter allows for graduated cutting of biological tissue or structure.

This disclosure details surgical instrumentation and related techniques for performing bone reconstruction surgeries. The surgical instrumentation may be used to size and shape a graft, such as an allograft. The appropriately sized and shaped graft is subsequently used to reconstruct damaged bone. A surgical instrumentation set is used to prepare the graft. The surgical instrumentation set includes a graft workstation, a plurality of sizing blocks and a plurality of cutting blocks.

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 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 provides a device, a kit for repairing and fixing articular cartilage, and a method for the same. The device comprises a costal cartilage rod, an outer sleeve, a drilling part, and an auxiliary implantation component; the drilling part comprises a drill sleeve and a drill bit matching an inner diameter of the drill sleeve; the auxiliary implantation component comprises a cartilage rod sleeve and an auxiliary pushing element, the costal cartilage rod has a rod-shaped structure with a diameter ranging from 3 mm to 8 mm and less than an inner diameter of the cartilage rod sleeve, and the costal cartilage rod is obtained from processing of costal cartilage. The costal cartilage is selected from the group consisting of autologous costal cartilage, allogeneic costal cartilage, or xenogeneic costal cartilage. Costal cartilage is processed into a costal cartilage rod by using the device provided in the present invention.

A system for repairing a glenoid defect of a specific patient can include a patient-specific punch and a patient-specific shaping block. The patient-specific punch can form a patient-specific glenoid implant from a bone puck. The patient-specific shaping block can shape the patient-specific glenoid implant to match and fill a glenoid defect of a specific patient.
