The compressing member has a threaded bore that engages a proximal end of a fixation member implanted in the bone such that, in response to rotation of the compression member, the interpositional member is sandwiched securely between the implant and the compression member. The conical surface of the implant compresses the interpositional member about a semispherical surface of the compression member, thereby restricting rotation of the implant.

  • Publication number: 20120089197
    Abstract: An arthrodesis anchor is formed as a monolithic piece for ease of handling and use, having two ends, one of which has prongs supporting barbs extending radially therefrom. The other end may have threads or barbs. A neck between may circular in cross section and be sized from about 0.045 inches to about 0.08 inches and may be conveniently sized at 0.062 inches for bending to accommodate final alignment of joints to be bonded. Optionally, a shank next to the neck may receive a tool for threading the anchor into a joint. The proximal and intermediate phalangial joints may be trimmed and pilot drilled, after which a first end may be inserted by a tool, typically into the proximal joint by threading or linear insertion of barbed prongs. The second end having barbed prongs may then be inserted into a pilot drilled into the base of the intermediate joint.

  • Patent number: 8062295
    Abstract: An improved method for attaching soft tissue to bone by passing a suture through an opening in the bone, e.g., a transosseous tunnel, and affixing the soft tissue with the suture. The improvement, for preventing the suture from migrating through the bone at the end of the opening, includes placing a eyelet into an end of the bone opening and passing the suture through the eyelet, as well as through the opening in the bone, in order to affix the soft tissue to the bone with the suture.
