Abstract: Surgical instruments for use in implanting a stem component into a knee of a patient include a canal reamer and an associated implant reference guide.

Abstract: Methods of surgically preparing a patient's tibia are disclosed. Some methods include positioning a guide tower on a surgically-prepared proximal surface above an opening of a medullary canal of the patient's tibia, attaching a stem trial to a lower end of an offset tool that is sized to be received in the guide tower, and advancing the stem trial through the guide tower and the surgically-prepared proximal surface into the medullary canal. The method may include moving the guide tower to a desired offset orientation on the surgically-prepared proximal surface and advancing a reamer through the guide tower into the medullary canal. The method may also include positioning a tibial base trial on the surgically-prepared proximal surface based on the desired offset orientation.

Abstract: A method of surgically preparing a proximal end of a tibia includes inserting an intramedullary orthopaedic surgical instrument into a medullary canal of the tibia, securing an attachment device to the intramedullary orthopaedic surgical instrument, attaching a cutting block to the attachment device, resecting the proximal end of the tibia using the cutting block to form a surgically-prepared surface, positioning a tibial base trial on the surgically-prepared surface, and inserting a keel punch through a slot defined in the tibial base trial and into the surgically-prepared surface of the tibia.

Abstract: An orthopaedic surgical instrument assembly is disclosed. The assembly includes a tibial base trial adapted to be positioned on a surgically-prepared proximal end of a patient's tibia, a base fastener, and a stem adaptor secured to the base fastener. The stem adaptor includes a first adaptor body engaged with a lower surface of the tibial base trial and a second adaptor body pivotally coupled to the first adaptor body. A stem trial is removably coupled to the second adaptor body of the stem adaptor.

Abstract: An orthopaedic surgical instrument assembly includes a tibial base trial adapted to be positioned on a surgically-prepared proximal end of a patient's tibia, an intramedullary orthopaedic surgical instrument engaged with a lower surface of the tibial base trial, and a fastener configured to pivot relative to the tibial base trial. The fastener is configured to engage with the intramedullary orthopaedic surgical instrument to removably couple the intramedullary orthopaedic surgical instrument to the tibial base trial.

Abstract: An orthopaedic surgical instrument assembly includes an attachment device, an intramedullary orthopaedic surgical instrument, and a cutting block. The attachment device includes a housing, a rail extending outwardly from the housing, and a mounting frame positioned on the rail that is configured to slide relative to the housing along the rail. The intramedullary orthopaedic surgical instrument is removably coupled to the housing, and the cutting block is removably coupled to the mounting frame.

Abstract: An orthopaedic surgical instrument assembly is disclosed. The orthopaedic surgical assembly includes a guide tower, an offset tool attached to the guide tower, and a stem trial. A guide tower includes a base surface adapted to be positioned on a proximal end of a patient's tibia and defining a first axis extending through the base surface. The offset tool is configured to rotate about the first axis. The offset tool includes a tool body that is positioned in the guide tower and is integrally formed with a shaft extending through an opening defined in the base surface of the guide tower. The stem trial is removably coupled to a lower end of the shaft.

Abstract: A multimedia memorial disposed at a grave site including a housing, power supply, an input, a memory, a microprocessor, a display for displaying a number of still images or successive moving images, a speaker, and an output. The multimedia memorial may also include a receiver and/or transmitter, such as a transceiver for receiving and/or transmitting information. Such a receiver may be configured for being responsive to global positioning system signals transmitted by a satellite navigation system and for providing information describing the memorial's location based on the navigation signals.
