Devices, systems, and methods for performing a transcorporeal microdecompression are described. The transcorporeal microdecompression may include a bone void plug allograft and specialized instruments for performing the procedure. This procedure may be performed under navigation and/or with robotic assistance.

An apparatus and kit for making holes of controlled depth and different diameters on chondral and osteochondral surfaces, comprises: a reamer member (2) having a cutting head (3) for removing tissue from said chondral and osteochondral surface (A), said member (2) being mobile approaching the chondral and osteochondral surface (A) for arranging the head (3) at said tissue; guide means (4) for guiding the reamer member (2) that can be firmly associated with the chondral or osteochondral surface (A), said reamer member (2) being slidable along said guide means (4); and mechanical means (5) for controlling the depth of the hole interposed between the reamer member (2) and the guide means (4) for defining an end stop of the reamer member (2) in the respective movement towards said chondral and osteochondral surface (A).

A retrograde cutting instrument and method of retrograde drilling using such an instrument. A method of forming a socket includes providing a retrograde cutter, inserting the cutter into a joint with a blade of the cutter in a straight position, pivoting the blade to a non-straight flip position, locking the blade in the flip position, and retrograde drilling a socket using the blade in the flip position.

A method for operating vacuum drill guide having an elongated structure having an internal axial passageway and having a drill bushing attached to a first end of the elongated structure, the drill bushing having an axial slot formed in a wall thereof communicating with the internal axial passageway, the drill bushing further having a longitudinal bore formed therethrough to receive a drill bit, a vacuum hose fitting communicating with the axial passageway at a second end of the elongated structure, a chip recovery chamber disposed along the internal axial passageway, and a vacuum filter disposed in the internal axial passageway between the chip recovery chamber and the first end the method comprising providing the vacuum drill guide, inserting a drill bit into the drill bushing, pulling a vacuum from the second end of the elongated structure, positioning the drill bit, and rotating the drill bit to perform a drilling procedure.

Apparatus for producing strips of bone fibre comprising a vice for securing a section of rigid bone with which said apparatus is used, said vice defining a containment area and having a compression axis with which a longitudinal axis of said bone is substantially aligned in use, an arm for reciprocal linear movement along a movement axis between a rearward position and a forward position, said movement axis being parallel with said compression axis and spaced therefrom in a lateral plane, a first drive mechanism for moving said arm along said movement axis in a reciprocal manner, and a cutting head comprising a first row of cutting teeth, which cutting head is mounted to a first end of said arm with said first row of cutting teeth coincident with said containment area and disecting said lateral plane, and a method of producing a DBM fibres product using such apparatus.

A cutting device is provided that includes an expandable tube having a base and a hollow interior for receiving the implant therein. The expandable tube includes cutting segments extending from the base and terminating to form a distal end of the expandable tube. At least one of the cutting segments has a cutting end with cutting teeth at the distal end of the expandable tube. Spring shaped sections are provided that extend the cutting segments. A method for removing an implant from a target bone is also provided based on the cutting device. A system for removing material directly surrounding an outer surface of an implant in an intramedullary canal of a target bone is also provided based on the cutting device and a sheath. A retractable opening is formed of leaflets at a distal end of the sheath, and a proximal end opposite the distal end.

Method and set of surgical instruments for fitting a shoulder prosthesis, and the shoulder prosthesis. The proposed method seeks to interpose a bone graft between the previously prepared glenoid surface (G) of a scapula (S) of a patient's shoulder and the face of a glenoid prosthetic component opposite the articular surface. The set of instruments permit the bone graft to be taken from the upper epiphysis of the humerus (H), either in situ or ex vivo.

Bone harvesting system including methods and devices for obtaining and/or removing osseous debris from a bone using an auger having a flexible, helical fin projecting from a shaft. In an exemplary method, a leading end region of the auger is placed into a reamed portion of a bone's medullary cavity via an entry site extending into the bone. Osseous debris is driven toward the entry site with the auger. At least a portion of the osseous debris that has passed through the entry site is collected outside the bone. In some embodiments, the leading end region of the auger is deformed by contact between the helical fin and a wall of the medullary cavity, to conform the helical fin in the leading end region to a portion of the medullary cavity.

A bone screw implant comprising a bone screw and a sleeve. The bone screw includes a first end, a second end opposite the first end, a cannula extending from the first end to the second end, an externally treaded portion provided between the first end and the second end, and at least one cutting flute. The at least one cutting flute extending from the first end toward the second end, where the cutting flute comprises at least one window extending through the cutting flute and in communication with the cannula. The sleeve comprising a cylindrical body portion extending about the second end of the bone screw, and a plurality of projections extending from the cylindrical body portion configured to engage bone as the bone screw is threadingly advanced.

A bone material removal device including a cannula, a bone drilling forward tip and a bore widening element including a bone carving portion that slides axially relative to the cannula and extends in a circumferential direction and wherein the axial movement of the bore widening element relative to the cannula brings a carving portions to travel and extend radially in a circumferential direction beyond a surface of the cannula and carve bone from a wall of a bore.
