  • Patent number: 10674955
    Abstract: 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.

  • Patent number: 7796843
    Abstract: 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.

  • Patent number: 7427200
    Abstract: 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.

  • Patent number: 6102957
    Abstract: An improved asymmetric femoral hip stem component for use in cementless hip replacement procedures is described. The stem comprises a proximal region having a novel three-dimensional configuration to allow for better fit and stability of the stem within the femoral intramedullary canal with minimal removal of strong bone therefrom. The stem further includes a twist isolated in the mid-stem region to improve fit while minimizing enlargement of the femoral canal. A distal end comprising a rotated internal slot is also described, wherein the slot reduces bending stiffness of the stem in both the coronal and sagittal planes.

  • Patent number: 5993455
    Abstract: A machining assembly, including a 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 means for subsequently 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.

  • Patent number: 5658351
    Abstract: A centralizer for the stem of a cementable prosthetic orthopedic implant that is implanted into the medullary canal of a bone has a hollow annular body with a tapered interior surface for receiving a tapered stem of the implant. The centralizer has four fins spaced around the exterior surface of its annular body with the fins extending radially outwardly in a direction generally perpendicular to the longitudinal axis extending along the stem in a proximal-distal direction. The annular body of the centralizer has a proximal and a distal end surface spaced a predetermined distance apart with the fins having a base adjacent the body extending over a substantial portion of the predetermined distance. Adjacent fins are offset from neighboring fins in a proximal-distal direction so that when the proximal-distal dimension of the annular body is maintained, it generates a wavelike structure for the centralizer body.

  • Patent number: 4896662
    Abstract: A proximal femoral sealing device is disclosed for use in the application of bone cement under pressure to a surgically prepared medullary canal of a femur prior to the implantation of a hip prostesis. The proximal femoral sealing device is formed of a generally solid body member with a passageway and a flexible annular wall member extending from the body member. The sealing device has an anatomically shaped outer surface, corresponding to the exposed endosteal surface of a prepared medullary canal. A chamber defined by a flexible annular wall and the body member opens into the medullary canal. In turn, the passageway communicates with the chamber and permits insertion of a cement nozzle therethrough into the chamber. In operation, the proximal femoral sealing device is placed within the proximal end of a surgically prepared medullary canal.
