    摘要: A screw, driving device, and method are provided for repairing a tissue injury of a patient, such as a meniscal tear in a knee or osteochondritis dissecans. The screw has a root, a distal section having a narrowing cross section toward the distal end, and a thread along at least a portion of the root between the proximal end and the distal end. Along a leading section extending from the distal end, the helical pitch is substantially constant; along a trailing section between the leading section and the root's proximal end, the helical pitch decreases. The substantially constant pitch along the leading section assists in preventing a stripping of the helical section. At the proximal end is a head having a diameter greater than a major root diameter of the central section. The head is for improving the tissue retention characteristics of the screw.

    摘要: An endoscopic surgical instrument for passing a suture through tissue includes a first jaw member, a needle, and a capture feature actuable to grip and retain the suture after the suture has been passed through a tissue body. An actuation mechanism can both move the needle between retracted and extended positions, and move the capture feature between open and closed configurations, via a single actuation. The capture feature may be a trap door which is axially translatable relative to the first jaw member to overlap a portion of the first jaw member and trap a portion of the suture between the trap door and the overlapped portion. The first jaw member may be movable relative to a second jaw member to grasp a tissue body. The instrument can grasp a tissue body, pass the suture through the tissue, capture and retain the suture without being repositioned relative to the tissue.

    摘要: A prosthesis for the replacement of at least a portion of the bone of a facet located on a mammalian vertebra, comprising: an articulating surface that articulates with another facet; a bone contacting surface that contacts a surface of the vertebra, the articulating surface being connected to the bone contacting surface; and a fixation element that attaches the bone contacting surface to the vertebra, the fixation element being adapted for implantation into an interior bone space of a pedicle of the vertebra; wherein the prosthesis is configured so that no portion of the prosthesis contacts the posterior arch of the vertebra.

    摘要: Apparatus and method is disclosed for securing a graft ligament in a bone tunnel. [In one form of the invention, the] A method is disclosed [comprises) comprising the steps of [(1)] forming a first bone tunnel [in a bone, the first bone tunnel having a first opening at one end thereof,] and [forming] a second bone tunnel [in the same bone, the second bone tunnel] being transverse to, and intersecting one another [, the first bone tunnel, the second bone tunnel having first and second portions extending from the first bone tunnel, the first portion of the second bone tunnel having a second opening at one end thereof, and the second portion of the second bone tunnel having a third opening at one end thereof]; [(2)] positioning a closed loop of a flexible member within the first bone tunnel and [the first] a portion of the second bone tunnel such that [a first portion of] the closed loop extends out of the first bone tunnel [opening] and [a second portion of the closed loop extends out of] the second [opening,] bone tunnel, parting the closed loop outside the second [opening] bone tunnel so as to create a first free end and a second free end, and passing the second free end through the opposite end of second bone tunnel [so that the second free end extends out of the third opening], and positioning the graft ligament over a portion of the flexible member extending out of the first opening; and [(3)] pulling [the first and second free ends of] the flexible member so as to draw the graft ligament into the first bone tunnel.
