Patient-specific guides for the Latarjet procedure, as well as surgical systems and methods of performing the Latarjet procedure to treat glenohumeral instability using such patient-specific guides are disclosed. A patient-specific coracoid guide and a patient-specific glenoid guide may be configured based on preoperatively generated three-dimensional models of the patient's shoulder anatomy. Guides may be configured for coracoid graft preparation and glenoid decortication. The coracoid graft may be placed in the desired position based on three-dimensional (3D) preoperative planning.

A system includes a first spacer sized and configured to be received within a resected bone space of a first bone and a second spacer sized and configured to be coupled to a second bone. The first spacer and the second spacer each include a body extending between a bone contacting surface and a coupling surface. At least one shim is positioned between the first and second spacers. The shim includes a body extending between a first coupling surface and a second coupling surface. The first spacer, the second spacer, and the at least one shim position the first and second bones in a predetermined alignment. An adjustable guide including a guide adapter and a guide body is configured to couple to the first spacer and is adjustable on a first axis.

A technique for correcting a bone deformity, such as a bunion, may be performed using an instrument that defines a spacer body connected to a fulcrum. The spacer body portion of the instrument can be inserted into a joint space between opposed bone ends. The fulcrum body can be inserted between adjacent metatarsals. An angle set between the spacer body and fulcrum body can help properly position both features within different joint spaces for ensuring that subsequent steps of the surgical procedure are properly performed and instrumentation is appropriately aligned.

The present disclosure relates to a guide for mandibular resection surgery, including, a guide plate having, at its lower side, a boundary surface that guides a resection pathway of a resection saw during a mandibular resection surgery; and a fixing portion that is formed to extend from the guide plate to be combined with a mandible or tooth, thereby fixing a position of the guide plate, wherein the guide plate is foldable.

Apparatus and methods are disclosed for determining and placing a first bony segment in relation with a second bony segment, both segments belonging to the same bone, including cutting said bone partially, to separate it into the first and second bony segment. The two bony segments are linked together by a bony hinge and placing the two boney segments in relation to each other may include distracting both bony segments around said hinge. The hinge may be configured to allow distraction of both bony segments around a single degree of freedom of the hinge and accommodate corrections in two substantially orthogonal planes.

A bone positioning device can include a fixation pin for attachment to a first bone and a fixation pin for attachment to a second bone. A first block having an aperture can be included for slidably receiving a fixation pin, and a second block having an aperture can be included for slidably receiving a fixation pin. A multi-axis joint can connect the first block and the second block, where the multi-axis joint allows the first second blocks to move with respect to each other about more than one axis.

Examples of the invention relate to methods, implants, and instruments for compressing first and second bone portions or a bone portion and an implant together.

A bone osteotomy guide or bone plate fixation implant whose anterior surface has a plurality of projecting members that are adapted to compress but not cut into the periosteum when positioned and affixed to the bone. Preferably, the projecting members are present as pointed or tapered structures, such as cones or pyramids, wherein the tips of the projecting members are blunt, truncated or rounded. The heights, widths, shapes, numbers and densities of projecting members on a given guide or fixation implant may vary. Because the projecting members compress the periosteum, the tips of the projecting members define a three-dimensional virtual surface that better conforms to the actual surface topography of the bone.

Osteotomy systems, devices, and methods for using the osteotomy systems are disclosed. The osteotomy system including an alignment device, at least one k-wire for insertion into the alignment device, and a cut guide with at least one hole for receiving at least one k-wire and a slot for receiving a saw blade. An osteotomy kit including an alignment device, cut guide, and position rotation device. The alignment device, cut guide, position rotation device, and bone plate are also disclosed. Finally, a method for fusing bones using the osteotomy system is also disclosed.

An example method includes obtaining, a virtual model of a portion of an anatomy of a patient obtained from a virtual surgical plan for an orthopedic joint repair surgical procedure to attach a prosthetic to the anatomy; identifying, based on data obtained by one or more sensors, positions of one or more physical markers positioned relative to the anatomy of the patient; and registering, based on the identified positions, the virtual model of the portion of the anatomy with a corresponding observed portion of the anatomy.
