An example method includes determining, by the one or more processors, an actual orientation of a surgical pin as installed in a bone of a patient; obtaining, by the one or more processors, a planned orientation of the surgical pin; determining, by the one or more processors and based on a comparison between the actual orientation of the surgical pin and the planned orientation of the surgical pin, whether the surgical pin was installed as planned; and responsive to determining that the surgical pin was not installed as planned, outputting, via a visualization device, virtual guidance to assist a surgeon in correcting the installation of the surgical pin.

A sacroiliac joint screw has a screw body having a head and a treaded shank with a self-drilling cutting tip. The screw body is cannulated and configured to receive a Steinmann pin for the purpose of a minimally invasive approach (MIS) for delivery to the sacroiliac joint (SI) while minimizing soft tissue damage. The self-drilling cutting tip creates a pilot hole. The threaded shank has a plurality of spiral cutting flutes, the spiral cutting flutes extend along a length of the threaded shank and are configured to provide a constant self-tapping feature. A plurality of bone harvesting windows are positioned in the spiral cutting flutes and are configured to pull in bone as the screw is advanced into the joint.

Devices, systems, and methods of bone stabilization. The bone stabilization system includes a variety of plates, including a tine plate. The tine plate may include an elongate body and first and second ears extending from the elongate body, each of the first and second ears defining a screw hole therethrough, and a first tine extending from the first ear and a second tine extending from the second ear, the first and second tines each terminating at a sharp point.

The present disclosure provides an apparatus comprising a wire having a first end and a second end opposite the first end. A first portion of the wire including the first end comprises a malleable region that is configured to remain deformed after bending, and a second portion of the wire including the second end comprises a superelastic region that is configured to return to a straight configuration after bending.

An osteotomy assistance kit includes a bone treatment assistance device and an attaching position confirmation device. The attaching position confirmation device includes a feature point indication rod to be applied via a tip portion to a feature point of the bone, a rod support unit that removably supports the feature point indication rod such that the tip portion is indicating the feature point of the bone, and a second support member that movably supports the rod support unit and indicates one of scales on the rod support unit. The bone treatment assistance device includes cutting slits, and first guide holes that guides first rods set to a predetermined positional relation. The second support member of the attaching position confirmation device is attached to the protrusion of the bone treatment assistance device.

A metatarsus adductus technique may involve cutting an end of one or both of a second metatarsal and an intermediate cuneiform to create a wedge-shaped opening between the end of the second metatarsal and the intermediate cuneiform. The method may further involve cutting an end of one or both of a third metatarsal and a lateral cuneiform to also create a wedge-shaped opening between the end of the third metatarsal and the lateral cuneiform. The second metatarsal and the third metatarsal can then be moved in a transverse plane to close a metatarsus adductus angle. Movement of the second and third metatarsal may close the wedge-shaped openings forming during bone cutting. With the second and third metatarsals appropriately realigned, the clinician can fixate the moved position of the second metatarsal and the third metatarsal.

Cutting elements may include points, tips, cutting portions and/or shafts of various geometries depending on requirements of the intended use. Tip geometries described may be used for cutting burrs, k-wires and/or drill bits in many types of applications. In particular, the tip geometries described may be used in medical applications. For example, tip geometries as described herein may be used for drilling bones, cartilage, and similar structures during surgery. Tip geometry may influence cutting ability. Use of the tip geometries described may allow the cutting element to be positioned at varying angles relative to the surface to be cut. In some instances, a tip geometry for a cutting element may be selected such that it reduces and/or inhibits movement of the cutting element during use and/or allows for a predetermined angle of entry into a surface to be cut. Using the designs described herein may reduce and/or inhibit damage, heat, and/or trauma to materials that are to be cut, for example, tissues such as bone and/or cartilage.

A device for registering a bone for a robotic shoulder arthroplasty with a surgical robot. The device can include a first portion engageable with a first portion of a bone and can include a second portion engageable with a second portion of the bone, the second portion connected to the first portion and rotatable with respect to the first portion. The device can include a registration device connectable to the first portion and configured to interface with the surgical robot for registration of the device and the bone. The device can include an actuator engageable with the first portion and the second portion to move the second portion toward a closed position away from an open position.

A retractor includes retractor blades and one or more shims coupled to one or more of the retractor blades. The shims can include features configured to fasten the shim to vertebral anatomy. Such features can facilitate the use a K-wire or barbed features. Example disclosed shim designs include those featuring a K-wire feature, a barbed feature, and a K-wire with barb design.

A method comprises the steps of: fixing a distal end of a first member of a surgical instrument with tissue, the surgical instrument including a second member having a longitudinal passageway configured for disposal of the first member and being connected with a navigation component such that the distal end is disposable with the passageway at a selected distance from the navigation component, the navigation component being positioned relative to a sensor to communicate a signal representative of an orientation of the first member; removing the second member from the first member; and connecting a third member with the first member along the orientation such that a distal end of the third member is fixed with the tissue. Systems, spinal implants, constructs and instruments are disclosed.
