Abstract: A system, apparatus, and method for determining a position of an orthopaedic prosthesis includes a patient support platform, a sensor array coupled to the patient support platform, and a controller electrically coupled to the sensor array. The sensor array is configured to generate data signals in response to an output signal of a signal source(s) coupled to the orthopaedic prosthesis and/or a bone of the patient. The controller is configured to determine a position of the orthopaedic prosthesis and/or the bone of the patient based on the data signals.

Abstract: A computer assisted surgery system includes a display for visual rendering of surgical data, a processor for receiving a control signal and performing operations associated with the control signal and for controlling the surgical data rendered by the display, and a wearable input device in communication with the processor. The wearable input device in one embodiment includes a mounting surface on a first side of the input device for mounting to a body portion of a user and a sensor assembly located on the side of the input device opposite the mounting surface.

Abstract: A number of orthopaedic surgical instruments are also disclosed. A method, apparatus, and system for fabricating such instruments are also disclosed.

Abstract: A method and system for designing a patient-specific orthopaedic surgical instrument includes coupling a knee sleeve to a leg of the patient. The knee sleeve includes sensors configured to generate sensor data indicate of the position of the respective sensor. The method also include determining angulation data indicative of the angulation of the knee based on the sensor data. The angulation data may be indicative of, for example, the ligament laxity of the knee. The method may also include generating a medical image(s) of the knee. The design of the patient-specific orthopaedic surgical instrument is determined based on the angulation data and the medical image(s).

Abstract: A bone saw tool includes a bone saw and a bone saw blade assembly. The bone saw blade assembly includes a bone saw blade and a bone saw blade guard. The bone saw blade guard is movable to an extended position to reduce the cutting effectiveness of the bone saw blade and/or the maximum cutting depth of the bone saw blade. The bone saw may be configured to activate the bone saw blade guard in response to a signal received from a computer system when the bone saw is moved outside a predetermined cutting region.

Abstract: An ankle prosthesis includes a tibial device attachable to a tibia. The tibial device has a concave articulating surface. A talar assembly includes a dome portion having a convex articulating surface engaging the concave articulating surface of the tibial device such that the dome portion is pivotable relative to the tibial device. The talar assembly also includes a base portion attachable to a talus. The base portion is pivotable relative to the dome portion.

Abstract: A head gear apparatus (10) is provided that moves air to cool a caregiver's head. The head gear apparatus (10) includes a helmet (12) that has a shell (114) configured to rest upon a head of a user and a fan housing (120) movably coupled to shell (114), a fan (122) is positioned to lie within fan housing (120) and moves with fan housing (120) relative to shell (114), and a garment (14) selectively coupled to helmet (12). Garment (14) includes a face shield (20).

Abstract: A tourniquet cuff (10) includes a first layer (20), a second layer (40), and a third layer (60). The first layer (20) has an inner side (22) impermeable to air and the second layer (40) has a first side (44) impermeable to air. The inner side (22) of the first layer (20) and the first side (44) of the second layer (40) cooperate to define a first cavity (96) formed to receive a gel-like material (15) therein. Further, the third layer (60) has an inner side (64) which cooperates with a second side (42) of the second layer (40) to define a second cavity (94) formed to receive pressurized air. The tourniquet cuff (10) adjustably secures about a patient's limb such that the gel-like material (15) is positioned between the patient's limb and the second cavity (94) to uniformly and comfortably distribute pressure around the patient's limb.
