Abstract: An orthopedic template configured to assist surgeons in removing a tibial implant previously implanted within a patient's bone. In use, the template provides a reference that mimics the underlying support member of the previously implanted tibial implant. That is, the template provides a representation or footprint that mimics the configuration of the underlying support member of a tibial implant, which cannot be readily seen when the tibial implant is inserted into a patient's bone. For example, the template may include a superiorly extending structure or a visual image that mimics the underlying configuration of the support member of the tibial implant. In use, the template may be positioned on a superior surface of the tibial implant. Thereafter, an instrument such as a bone cutter, can be used to trace the representation formed on the template while simultaneously cutting or removing bone beneath the tibial tray.

Abstract: Disclosed are techniques to navigate soft tissue structures based on preoperative imaging for joint arthroplasty. Particular embodiments are useful for direct anterior approach total hip arthroplasty but may be applicable in other approaches and/or other surgical procedures.

Abstract: Methods for measuring tissue defects include the use of a suture anchor, a drill guide, a needle driver, and a ruler. Using the drill guide, the surgeon extends the suture attached to an implanted anchor between the first and second ends of the defect. The surgeon then attaches a needle driver to the suture extending from the proximal end of the drill guide. Finally, the surgeon retracts the suture back through the drill guide and measures the distance between the needle driver and the proximal end of the drill guide to determine a length of a graft needed to repair the defect.

Abstract: Methods for suspension fixation most applicable for a Latarjet of bone block procedure are performed using an open surgery with an anterior approach. The method passes endobuttons and sutures through the glenoid from posterior without the need of a posterior drill guide and disposable drill/sleeve. As an alternative embodiment, a passing pin with a slot at the advancing end may be used to further reduce surgical steps. The passing pin may be advanced and exit the muscle, and the suture loop may be directly attached to the pin rather than a secondary shuttle suture and then retrieved anteriorly.

Abstract: Methods and apparatus for performing joint laxity measurement are disclosed. A retractor includes a plurality of spacers, such as plates, that are capable of being moved from a central portion of the retractor by a carriage mechanism. In some cases, the carriage mechanism may press against ramps connected to internal sides of the plates, thereby causing the plates to be displaced outwardly. In other cases, the carriage mechanism may include blades that rotate and press against the internal sides of the plates, thereby causing the plates to be displaced outwardly. The retractor is mounted on a surgical device configured to actuate the carriage mechanism. When the retractor is placed in a joint and the carriage mechanism is actuated, a measurement of the joint laxity may be determined based upon characteristics of the retractor and/or the surgical device.
