    Abstract: An apparatus for anchoring at least two graft ligaments within a longitudinal bone tunnel includes a longitudinal sleeve having at least two radially spaced ligament-contacting surfaces located in lateral opposition to a sleeve inner lumen. The sleeve is configured for at least partial insertion into the bone tunnel with each graft ligament positioned laterally adjacent a different ligament-contacting surface. The graft ligaments are at least partially located between the bone tunnel and the sleeve. An actuating member has longitudinally separated proximal and distal actuating member ends. An asymmetrically offset profile is defined by at least one of the sleeve and the actuating member. The asymmetrically offset profile has a plurality of longitudinally spaced engagement thresholds. The actuating member is inserted longitudinally into the sleeve to cause frictional engagement of each graft ligament with both the bone tunnel and at least one ligament-contacting surface.

    Abstract: Surgical repair systems and techniques for plantar plate repairs. The surgical repair systems and methods reconstruct the plantar plate through a dorsal incision. The surgical repair system embodies a variety of instruments that provide visualization and access to the plantar plate using suture to complete the repair. The repair system may include some or all of the following instruments: a metatarsal head pusher employed in open surgical space, to move the “capital fragment” in a controlled manner; a suture retriever instrument and a suture retriever funnel (sleeve); a suture passer such as a Mini Scorpion DX and accompanying needle, or a variety of shaped Micro Suture Lassos; a measuring guide; and a small joint distractor.

  • Publication number: 20130184819
    Abstract: A radially expandable sheath is provided having a substantially closed distal end with at least two sidewalls extending proximally therefrom and defining a central lumen. Each sidewall can have a substantially concave outer surface adapted to seat a graft member, and each side wall is at least partially separated by a longitudinally oriented slot that extends from a proximal end along a substantial length of each sidewall. The slot preferably terminates at a position just proximal to the distal end. The device can also include a sheath expander that is adapted to be disposed in the central lumen of the radially expandable sheath and that is configured to flex the sidewalls to radially expand the sheath so as to fix a graft member within a bone tunnel.

  • Patent number: 8480692
    Abstract: Disclosed are medical devices and methods for tendon, ligament, and soft tissue repair. A method includes introducing a first segment having a delivery assembly into a first soft tissue, and removing the delivery assembly to expose an opening of a hollow body of the first segment. The method also includes introducing a second segment having a second delivery assembly and a second body into a second soft tissue, guiding the second delivery assembly through the opening, and advancing the second body into the hollow body, thereby joining the first soft tissue and the second soft tissue.

  • Publication number: 20130172998
    Abstract: Methods and devices are provided for fixing a ligament graft in a bone tunnel. In general, the methods and devices involve affixing a ligament graft within a bone tunnel using an adhesive. A fixation device can be inserted through the ligament graft in a direction transverse to an axis of the tunnel to maintain the ligament graft in contact with the adhesive. The fixation device can be removed when the adhesive is cured such that the ligament graft is fixed in the tunnel.

  • Patent number: 8470037
    Abstract: A system for reconstructing a ligament by fixing at least one graft ligament strand in a bone tunnel is provided. The system a retainer configured for disposition in the bone tunnel, the retainer including a crosshole for receiving a locking pin and a mounting shoulder formed about the crosshole, and a cap removably attached to the retainer for capturing the at least one graft ligament strand by compressing the at least one graft ligament strand between the cap and the retainer, wherein the cap includes at least one locking member configured to engage the mounting shoulder of the retainer to facilitate gripping of the at least one graft ligament strand between the cap and the retainer.

  • Patent number: 8470038
    Abstract: The present invention relates to a bone-tendon-bone graft and components. Embodiments of the present invention comprise an intermediate bone block that is used to adjustably secure soft tissue (e.g., tendon) in a patient. Embodiments of intermediate bone blocks of the present invention are used singly or in combination with one or more bone blocks to form a bone block assembly for securing soft tissue. The present invention further relates to an assembled bone-tendon-bone graft for implantation in humans comprising the intermediate bone block and a length of soft tissue. A bone-tendon-bone graft comprises a length of soft tissue extending from a first assembled bone block to a second bone block and then doubles back to said first assembled bone block. Depending upon the embodiment, the second bone block fixedly or slideably attaches to the length of soft tissue and facilitates it doubling back to the first assembled bone block.

  • Patent number: 8465545
    Abstract: A material fixation system is particularly adapted to improve the tendon-to-bone fixation of hamstring autografts, as well as other soft tissue ACL reconstruction techniques. The system is easy to use, requires no additional accessories, uses only a single drill hole, and can be implanted by one person. Additionally, it replicates the native ACL by compressing the tendons against the aperture of the tibial tunnel, which leads to a shorter graft and increased graft stiffness. It is adapted to accommodate single or double tendon bundle autografts or allografts. It also provides pull out strength measured to be greater than 1000 N.
