  • Patent number: 10080574
    Abstract: A novel coplanar X-ray guided method and device for insertion of distal locking screws in intramedullary bone nails. The device has coplanar holes, which allow insertion of protective sleeves. A drill and bone screws can be inserted through the protective sleeves. Radiopaque target markers in the aiming arm enable the easy positioning of an X-ray source such that an X-ray beam is coplanar with the aiming arm transverse holes. After the X-ray source is accurately oriented, a single X-ray snapshot is enough to assess the exact distortion of the implanted intramedullary nail. The X-ray beam need not be coaxial with the intramedullary nail holes. The aiming arm has a mobile portion and a fixed portion fastened to the nail, wherein said aiming arm can be adjusted, displacing the mobile portion over the fixed portion, to compensate for the distortion of the intramedullary nail after implantation.

    Abstract: A system for establishing an intramedullary path includes a body sized and configured to be received within a resected bone space. The body defines a first aperture that extends through the body and is sized and configured to receive a surgical tool therethrough. A first bone engaging structure extends from the body in a first direction and includes a first surface that is complementary to a surface topography of a first bone. When the first surface of the bone engaging structure engages the surface topography of the first bone to which the first surface is complementary, an axis defined by the first aperture is substantially collinear with a mechanical axis of the first bone.

    Abstract: Methods and devices are provided for implanting a cross-pin through a bone tunnel, such as in an arthroscopic surgical procedure. In general, the methods and devices allow a cross-pin hole to be formed in a medial side of a knee bone such that it intersects a bone tunnel formed in the knee bone. In one embodiment, a cross-pinning guide device is provided that can be configured to angularly position the cross-pin hole relative to the bone tunnel to allow the cross-pin hole to intersect the bone tunnel without passing through another side, e.g., a lateral side, of the knee bone. The knee bone can be a femur or a tibia such that the cross-pin hole and the bone tunnel can each be entirely formed in the femur or in the tibia.

  • Publication number: 20130030444
    Abstract: A universal targeting apparatus includes a generally U-shaped body having one end configured to be coupled to the proximal end of the intramedullary implant and a mounting portion at an opposite end of said body. An arm is rotatably mounted to the mounting portion of the U-shaped body and includes bores defined at its opposite ends. Each bore is arranged at a different angle to correspond to the angle of a transverse aperture in the intramedullary implant. The arm can be rotated so an appropriate one of the angled bores is aligned with the transverse aperture to serve as a guide for creating targeting holes in the bone.

  • Patent number: 8361079
    Abstract: Methods for drilling enlarged osteal tunnels using osteal guides capable of drilling an angled osteal tunnel, namely, an osteal tunnel having an angle or turn within the bone and for drawing a muscle, tendon or ligament in need of repair into the enlarged osteal tunnel such that the bone can mend about, around, over and/or within the muscle, tendon or ligament. A reamer and guide wire can be used to create the enlarged osteal tunnel to accommodate a portion of the muscle, tendon or ligament in need of repair. The device allows for the blind intraosseous preparation of osteal tunnels and the blind intraosseous retrieval of sutures from such osteal tunnels.

  • Publication number: 20130023891
    Abstract: A device for preparing multiple channels in a bone comprises a handle, a single guiding sleeve mounted removable at said handle and an arm projected from said handle. Said single guiding sleeve comprises a central first guiding channel for receiving a first aiming wire, a second guiding channel for receiving a further aiming wire, said channels have parallel axes. At least one cannulation is provided, a central longitudinal axis thereof runs at a distance and parallel to the guiding channels. Said at least one cannulation being arranged offset in a circumferential direction to said second channel. An aiming wire introduced in said second channel can be replaced into a cannulation by pulling off the guiding sleeve turning it about the first aiming wire and reinserting the turned guiding sleeve into said handle.

  • Patent number: 8317862
    Abstract: A method of providing a replacement anterior cruciate ligament (ACL) provides a tibial tunnel and at least one femoral tunnel for receiving the replacement ligament, the femoral and tibial tunnels not being colinear but rather in an orientation that more closely mimics the natural ACL. The femoral tunnel is formed through the anterior medial portal. A cross pinning guide having a femoral rod for insertion into the femoral tunnel, a spaced apart arc shaped track and a guide block having one or more bores aligned with the femoral rod whereby an instrument inserted through one of the bores creates a pilot hole for the cross pin which intersects the femoral tunnel and an appropriate angle thereof which avoids ligaments and other sensitive tissue can be selected by adjusting the guide block along the track.
