摘要:
Methods of selecting and implanting prosthetic devices for use as a replacement meniscus are disclosed. The selection methods include a pre-implantation selection method and a during-implantation selection method. The pre-implantation selection method includes a direct geometrical matching process, a correlation parameters-based matching process, and a finite element-based matching process. The implant identified by the pre-implantation selection method is then confirmed to be a suitable implant in the during-implantation selection method. In some instances, the during-implantation selection method includes monitoring loads and/or pressures applied to the prosthetic device and/or the adjacent anatomy. In some instances, the loads and/or pressures are monitored by a trial prosthetic device comprising one or more sensors. Methods of implanting meniscus prosthetic devices are also disclosed.
摘要:
A stem-like bone implant (10) includes longitudinal structural members (16A) and tension cables (31) that provide curvature control, support and rigidity against bending and buckling. The longitudinal structural members (16A) and tension cables (31) may become an integral part of a composite regenerated bone having a substantially increased strength over natural bone. The flexibility of the implant (10) is controlled by specifically varying the structural geometry of certain portions of the implant and by adjusting the tension in the tension cables (31) before, during and after the implantation operation to thereby adjust the stiffness of the implant. The tension cables (31) may be adjusted to produce asymmetric or non-uniform levels of tension in the longitudinal structural members (16A).
