The present disclosure generally relates to a surgical tool for use in shoulder arthroplasty. The surgical tool includes a humeral head cut guide configured to fit within a rotator interval of a subject in need of shoulder arthroplasty. The cut guide can further include a top surface, a bottom surface, a front surface, a back surface, and at least two sides. The surgical tool can also have at least two nonconverging pin holes and a receiving portion configured to permit reversible attachment of the cut guide to an attachment arm assembly.

Described herein is a device for treating a narrowed region of a lumen in the ear or nose of a patient, the device comprising: an elongated tube; at least one shock wave emitter, the at least one shock wave emitter configured to generate at least one shock wave along a working direction; at least one imaging sensor oriented to capture images along the working direction; and a fillable member sealed to a distal end of the elongated tube and surrounding the at least one shock wave emitter and the at least one imaging sensor, the fillable member fillable with a conductive fluid.

A targeting system is disclosed. In use, the targeting system is configured to target (e.g., aim, locate, etc.) a fastener opening in a bone plate, more particularly, a variable angled fastener opening formed in a periphery of a periprosthetic bone plate. In one embodiment, the targeting system includes an alignment guide including a plurality of combo-slots for targeting a plurality of openings formed in the periprosthetic bone plate. In addition, the targeting system includes a plug configured to be positioned within the combo-slots formed in the alignment guide. In use, positioning the plug into the combo-slot formed in the alignment guide transforms the combo-slot into a substantially circular hole or opening with a predefined trajectory aligned with one of the variable angled openings formed in the periphery of the periprosthetic bone plate thereby defining a trajectory from the alignment guide to the variable angled opening.

An assembly for preparing bone stock includes a shell comprising a base having a support surface, and a lid. The base and lid have a void space therebetween. A carriage is disposed at least partially within the void space, and moveable across the support surface. The carriage comprises a wall, at least a portion of which is resiliently deformable. The wall cooperates with the base to define a preparation chamber, and a removal element configured to remove soft tissue from the bone stock is disposed at least partially therein. The resilient portion of the wall is configured to deform when bone stock is positioned between the removal element and the wall. The carriage is configured to receive power from a drive train to actuate movement of the carriage across the support surface, and the removal element is also configured to receive power from the drive train.

Surgical instruments, systems, and methods for performing an osteotomy are disclosed herein. A surgical system includes a body with a distal end, a proximal end, a first surface, and a second surface. The surgical system can include cutting blades positioned on the first surface and/or the second surface. The surgical system can include columns of cutting blades positioned on the first surface and/or the second surface. The surgical system can include rows of cutting blades positioned on the first surface and/or the second surface.

A system for providing fixation of first and second bones includes a drill guide that receives a drill bit to create first and second holes in the first and second bones, respectively. Guide pins can be driven into the first and second holes. The guide pins are received by a surgical saw to guide the surgical saw toward a joint between the first and second bones, thereby creating a third hole in each of the bones across the joint. The guide pins are then removed, and an implant can be inserted into the bones, such that a first leg of the implant is disposed in the first hole, a second leg of the implant is disposed in the second hole, and a keel of the implant is disposed in the third hole.

An orthopedic impactor may include a motor operable to generate first rotational motion and second rotational motion, a linear motion converter operatively coupled to the motor to convert the first rotational motion into first linear motion and the second rotational motion into second linear motion, an anvil including at least one impact surface, and a thrown mass having a first position located a distance from the at least one impact surface. The thrown mass may accelerate, responsive to the first linear motion and away from the first position, toward the anvil to impact the at least one impact surface with a first kinetic energy and impart a linear impact force on the anvil. The thrown mass may return, responsive to the second linear motion and toward the first position, with a second kinetic energy that is less than the first kinetic energy.
