A bone screw includes a shaft including at least one thread having an external thread form and defining at least one cavity. The shaft includes at least one tissue gathering member disposed to direct tissue into the at least one cavity. In some embodiments, systems, spinal constructs, surgical instruments and methods are disclosed.

An orthopaedic surgical instrument includes a customized patient-specific 5-in-1 cutting block having a plurality of ribs and cutting guide slots extending between each rib. A bone-facing surface of each rib has a customized patient-specific negative contour configured to receive a portion of a corresponding positive contour of the patient's femur.

Aspects of present disclosures involve systems, methods, and apparatus for a bone mounted robotic-assisted orthopedic surgery system for precise implant position, soft tissue balancing, and guidance of tools during a surgical procedure, particularly partial or total knee replacement procedure. The system features a bone-mounted robotic arm with an end-effector for precise positioning of a surgical tool, positioning of implants, and balancing of soft tissues. The reconfigurable robotic system requires minimal training by surgeons, is intuitive to use similar to conventional instrumented surgery, and has a small footprint. The system works with existing, conventional instruments, patient-specific instruments, sensor-assisted systems, and computer-assisted systems and does not require increased surgical time and safely provides the enhanced precision achievable by robotic-assisted systems and computer-assisted technologies.

A tibial component placement guide for use in a knee arthroplasty procedure involving a knee joint comprising a tibia, a patella, and a femur, the tibial component placement guide comprising an overlay configured to be overlaid a resected tibia that typifies at least one of a shape and an outline of the resected tibia, the overlay including at least one of an indicia and an opening indicative of at least one of an orientation and a position of a presurgical kinematic axis of at least one of the femur and the patella.

A cutting guide for periacetabular osteotomy comprises at least one first main body having a longitudinal opening for the insertion of a cutting instrument, extending from a first end to a second end of the first main body and at least two positioning and fixing arms extending away from the first main body from opposite sides with respect to the longitudinal opening, in order to correctly position the first main body on a bone and fix it thereto through respective fastening members.

Systems and methods may be used to perform robot-aided surgery. A system may include a display device and a computing device including a memory device with instructions. The instructions can cause the system to access surgical data, calculate medial and lateral gap data, calculate a recommended component set, and generate a graphical user interface. Accessing surgical data can include accessing soft tissue data indicative of at least tension in soft tissues surrounding a surgical location. The graphical user interface can include an interactive trapezoidal graphic overlaid onto a graphical representation of a distal femur and a proximal tibia. The interactive trapezoidal graphic can include a graphical representation of a medial total gap, a lateral total gap, and a recommended spacer size. The interactive trapezoidal graphic can update in response to adjustments in implant parameters to assist in surgical planning.

A method of designing a guide tool for cartilage repair in an articulating surface of a joint, comprising the steps of: I. determining physical parameters for cartilage damage in a joint and generating design parameters for cartilage repair objects and their relative placement in a predetermined pattern. comprising: II. selecting repair objects to fit the individual cartilage damage site wherein the repair objects have: cross sectional areas adapted to fit the surface area of the cartilage damage site, lengths adapted to fit the selected joint and/or type of cartilage damage, and surfaces intended to align with the articular cartilage surface in the joint, based on the healthy surface contour curvature, III. determining, based on obtained image data, positions and angles of the selected cartilage repair objects, wherein the positions and angles are adapted so that the selected repair objects fit the individual cartilage damage site, IV. generating design parameters of the guide tool, for placement of the cartilage repair objects comprising the following steps of: generating the design for an upper part and a lower part of a guide channel in a guide body extending from the positioning body, said guide channel passing through said positioning body and said guide body wherein the angles and positions are generated dependent on and substantially corresponding to the determined angles and positions of the selected cartilage repair objects. and wherein the design for the lower part of all the guide channel is generated dependent on and substantially corresponding to the determined cross sectional areas, of the selected cartilage repair objects.

Embodiments of the present disclosure are directed to instrumentation that facilitate coracoid-glenoid fixation in Latarjet procedures. For example, a single instrument, a coracoid resection tool, may be provided/utilized to prepare a coracoid bone graft for size, flatness, and hole drilling. A glenoid drill guide may further be provided/utilized that uses sized offsets for placement of the coracoid graft flush with the glenoid. Further embodiments of the disclosure are directed to corresponding methods that employ this instrumentation. For example, a surgeon may employs the coracoid resection tool as a guide to plane the inferior coracoid surface that will serve as the coracoid graft surface. The coracoid resection tool may further guide the placement of coracoid holes along the length of the coracoid and orient the holes approximately perpendicular to the planed coracoid graft surface. For example a proximal coracoid hole may be positioned towards the proximal end (i.e., the cut end) of the resected coracoid while a distal coracoid hole may be positioned towards the distal end (i.e., the tip) of the resected coracoid.

A femoral component and a tibial component are respectively configured to exclusively couple with the distal end of a femur bearing a femoral prosthesis and with the proximal end of a tibia bearing a tibial prosthesis. The femoral component has a distal portion configured to face the distal end of the femur, bearing distal positioning holes facing a distal region of the femoral prosthesis. A frontal portion extends on the continuation of the distal portion and has a first abutment area operating against the femur bone part and a second area facing a frontal region of the femoral prosthesis. The frontal portion has at least two guide holes at the first abutment area, and at least two frontal positioning holes at the second area.

An apparatus for providing structural support to an anatomical structure is disclosed. The apparatus comprises a plurality of connection structures and a frame structure. Each of the plurality of connection structures is arranged that, in use, they are connected to at least two points on an anatomical structure. In use, each connection structure is arranged to be orientated in a predetermined orientation and to be separated from each other connection structure by a predetermined separation. The frame structure connects each of the plurality of connection structures. The frame structure is arranged to maintain the predetermined orientations of the plurality of connection structures and the predetermined separations between the plurality of connection structures.
