  • Patent number: 10966772
    Abstract: Various forms of a cable fixation device, instrumentation, kit, and methods useful for repairing the skeletal system are introduced. The system utilizes a clamp housing fixing a head end of a surgical cable therein. In an operative configuration the cable is looped around a damaged bone segment and reentered through a lock aperture in the clamp housing then through a multi-part collet and lock cap residing within a lock aperture. The cable loop and each aforementioned component comprise a central axis aligned within a single plane. A sliding interface situated between the lock cap and collet prevent twisting of the surgical cable. The locking mechanism is non-destructive to the cable despite repeated unlocking and relocking of the fixation device. The axis for tensioning of the cable is coincident with the locking axis. A cerclage inserter instrument is disclosed.

  • Patent number: 10485599
    Abstract: Surgical cable passer instruments and methods for passing surgical cable around a bone through a surgical incision are disclosed. First and second handle tube portions comprise respective cable guide tubes and handle extensions. A proximal portion of the cable guide tube portions is fixed to a distal portion of the respective handle extension. Each handle tube portions comprise a cannula extending between a near port at a proximal end and a far port at a distal end for passage of surgical cable therebetween. Arc segments of a first cable guide tube and a second cable guide tube define a bone aperture therebetween for passing around a bone. A releasable hinge portion joins a first handle tube portion and a second handle tube portion at distal ends of a first and second handle extension.

  • Patent number: 10376379
    Abstract: Instruments, kits, and methods are disclosed for installing an implant spacer through an incision and down a surgical corridor. The instruments also serve to align a drill guide and align and insert a spacer stabilizer for stabilization of adjacent bone portions. An inserter instrument comprises an elongated guide bar body having a guide portion for aligning instruments with said spacer and for introducing a stabilizer to secure the spacer in a predetermined position between the bone portions. In preferred embodiments a stabilizer implant portion comprising a base wall separated by a retaining member by a web wall is introduced into a pre-bored hole in a bone and secured with a stabilizer anchor extending through a central bore. Included is a retractable graft block for securing graft material within an aperture of a spacer during insertion of the spacer.

  • Publication number: 20190183547
    Abstract: A bone plate system having a retainer for resisting back-out of a bone anchor from a throughbore of a bone plate is provided. In one aspect, a bone plate system having a resilient retainer disposed in a bone plate throughbore with a pair of elongate arm portions of the resilient retainer extending along opposite sides of the throughbore. In another aspect, a bone plate system having a resilient retainer with a pair of elongate interference portions completely exposed in the throughbore and spaced from each other across the throughbore to retain a head of a bone anchor received in the throughbore. In addition, a bone plate system having a resilient retainer with a pair of opposite end portions disposed within a groove of a throughbore wall such that a bone anchor may be inserted into the throughbore without contacting either of the opposite end portions of the retainer.

  • Publication number: 20180098799
    Abstract: A cable bone screw implant and insertion instrument assembly comprising an implantable bone screw having an enlarged head portion. An enlarged head comprises a lock aperture and an insert aperture and holds a deformable stress tube for housing a surgical cable. A lock screw resides in the lock aperture. A control mate on the enlarged head engages with an inserter instrument which comprises an arm rod portion having a driver cannula for housing a locking rod instrument. An end of the elongate rod body is enlarged having a first and second deflector arm. An interlock engages a cable bone screw implant portion. A compression taper on the arm rod portion compresses deflector arms securing the implant. An outer tube housing engages the deflector arms. Sliding the outer tube housing locks or releases the implantable bone screw. A surgical cable is tensioned between two cable bone screw implants for fixation.

  • Patent number: 9439698
    Abstract: Various forms of a cable fixation device, instrumentation, kit, and methods useful for repairing the skeletal system are introduced. The system utilizes a clamp housing fixing a butt end of a surgical cable therein. In an operative configuration the cable is looped around a damaged bone segment and reentered through a lock aperture in the clamp housing then through a collet and lock cap residing within the lock aperture. The cable loop and each aforementioned component comprise a central axis aligned within a single plane. A sliding interface situated between the lock cap and collet prevent twisting of the surgical cable. The locking mechanism is non-destructive to the cable despite repeated unlocking and relocking of the fixation device. The axis for tensioning of the cable is coincident with the locking axis. A counter torque instrument has a torsional input shaft generally perpendicular to the elongated axis of the instrument.
