    摘要： A system and method for detecting lubrication conditions, lubrication regimes, impingement, stick-slip, and/or surface damage allows the health of a joint to be monitored. The system and method provides in situ or in vivo real-time monitoring of dynamic and static conditions of the joint. The monitoring system may use both passive and active sensing approaches that employ strategically placed piezoelectric transducers on/in the articulating components of the joint. In some embodiments, the transducers may be Lead Zirconate Titanate (PZT) transducers. Active sensing may be used to detect lubrication regimes under static and dynamic conditions. Passive sensing may be used to characterize the joint motion and abnormities, such as impingements and surface damages.

    摘要： A displacement sensor based on the underlying principle that when the outer surface of a quartz fiber (fiber optic cable) is etched to form a series of regularly spaced lines (a Fiber Bragg grating), laser light of a wavelength matching the spacing of the lines which enters one end of the fiber will be preferentially reflected. If the fiber is deformed, causing the line spacing to change, the wavelength of the reflected light will also change. This shift can be accurately measured and so can be related to the magnitude of the deformation of the fiber. This fiber is potted with epoxy resin in a narrow tube fabricated from a shape-memory alloy (SMA), and pre-formed into a curved shape. This not only protects the quartz fiber from direct contact with other objects and excessive bending, but also causes it to deform in a predictable fashion, thereby generating a reproducible response to displacement. Due to the high elastic behavior of the SMA tube, a displacement sensor with a gage length of 40 mm can measure displacements in excess of 3 mm.

    摘要： An apparatus and method for making one or more grooves in the medullary canal surface of a bone to secure and reduce the risk of rotational failure of implanted orthopedic endoprostheses. The apparatus includes a head and, attached thereto, a body adapted for insertion into the medullary canal of a bone. The apparatus also includes a channel therethrough that is enclosed in the head and open in the body. One or more grooves is made in the medullary canal surface of a bone by placing the body of the apparatus in the medullary canal, inserting a cutting device in the channel, and then using the cutting device to remove an amount of bone tissue sufficient to form a groove or grooves. The risk of rotational failure of implanted orthopedic endoprostheses is reduced by implanting prostheses that engage and are secured in place by the groove or grooves.

    摘要： A method is disclosed for analyzing surgical techniques using a computer system for gathering and analyzing surgical data acquired during a surgical procedure on a body portion and comparing that data to pre-selected target values for the particular surgical procedure. The inventive method allows the surgeon, for example, to measure the technical success of a surgical procedure in terms of quantifiable geometric, spatial, kinematic or kinetic parameters. The method comprises calculation of these parameters from data collected during a surgical procedure and then comparing these results with values of the same parameters derived from target values defined by the surgeon, surgical convention, or computer simulation of the same procedure prior to the operation itself.

    摘要： A machining assembly, including a of the disclosure novel broach design, are disclosed for preparing a femoral medullary cavity for receipt of a femoral prosthetic stem, wherein the configuration of the implantation site allows for the neutral alignment of the prothesis within the medullary cavity for improved rigid fixation of the prosthetic stem therein. Aspects of the inventive machining assembly include a novel broach comprising a proximal lateral recess that allows for initial avoidance of the greater trochanter during implantation, thereby resulting in the preparation of a neutrally aligned cavity with respect to the broach. The machining assembly also includes a guide and a second cutting instrument for removing the bone of the greater trochanter once neutral alignment between the medullary cavity and broach are achieved for the subsequent implantation of a neutrally aligned femoral prosthesis.
