  • Publication number: 20210298909
    Abstract: A medical implant which comprises a porous lattice is fabricated with additive manufacturing techniques such as direct metal laser sintering. A CAD model of the porous lattice is created by defining a trimming volume and merging some lattice elements with adjacent solid substrate.

  • Publication number: 20210228366
    Abstract: A modular augment cone system and methods of implanting the modular augment cone system. The system includes a main body cone a first cutout in the cone wall, and including a proximal end, a distal end, and a cone wall extending between the proximal and distal ends. A portion of the cone wall proximal to the first cutout includes an attachment feature. A first augment cone is positionable in the first cutout, the first augment cone including an attachment feature configured to mate with the attachment feature of the cone wall to attach the first augment cone into the first cutout. The main body cone can include a second cutout in the cone wall. In such systems, the modular augment cone system can include a second augment cone configured to mate with an attachment feature of the cone wall to attach the second augment cone into the second cutout.

  • Patent number: 10710254
    Abstract: A safety cutting device includes a slidable insert that moves longitudinally within a cavity of a housing. The slidable insert has a cutting blade attached and moves within the housing from a safe position in which the blade is covered to an exposed position for cutting. The safety device has a release button with a first lock configured to lock the insert in the exposed position upon moving before actuation of the release button, and a second lock that maintains the insert in the exposed position after actuation of the release button but before the button is release. A biasing member automatically retracts the blade when the release button is actuated and released.

  • Publication number: 20200069442
    Abstract: An implant assembly for a long bone having a longitudinal axis. The implant assembly has a stem that is received in a surgically prepared medullary canal of the long bone. The stem defines at least one transverse through-opening that extends through the stem from a first portion of the outer surface of the stem to an opposed second portion of the outer surface of the stem. Each transverse through-opening has a central axis that is substantially perpendicular to the longitudinal axis of the stem. Each transverse through-opening receives a fastener and has a longitudinal dimension, measured relative to the longitudinal axis of the stem, that is sufficient to permit axial movement, relative to the longitudinal axis of the stem, of the stem relative to each fastener.
