  • Publication number: 20100280555
    Abstract: A method of performing vertebral facet fusion by lateral approach and related devices. The lateral approach to facet fusion involves identifying the lateral mass and introducing any of the fixation methods known or described herein laterally at one or more facets through the use of a Kirschner wire guide, a cannulated bone drill and cooperatively cannulated staple guide. A surgical bone staple have a perforated bridge is used across the lateral facet joint where fixation is required. Where fusion is desired, a bone screw have lateral perforations of the shank is inserted through the cannulated staple guide and bridge perforation at the joint to promote fusion. A staple cap and graft container for overlay grafting may be utilized for additional fusion. The method involves less surgical time, reduced blood loss and discomfort for the patient as compared to the posterior approach.

  • Patent number: 7686838
    Abstract: A surgical anchor device for the repair of a torn ligament or tendon, primarily the anterior cruciate ligament in the knee, is used to affix the ligament within a femoral bone tunnel in the distal portion of the femur from the intra-articular surface, the device providing a pulley for a suture, wherein a free end of the suture may be pulled away from the device to draw the suture attached to the ligament graft within the femoral bone tunnel securing the ligament graft within the bone tunnel. Installation of the device is provided by insertion of the device through a tibial hole, through the femoral tunnel out of the lateral femoral cortex, pulling the attached sutures simultaneously to flatten the device against the lateral femoral cortex, attaching one end of the suture to the ligament graft and pulling the other end of the suture until the graft is situated properly within the femoral bone tunnel and tying the free end of the suture to retain the graft within the femoral bone tunnel.

  • Patent number: 7674274
    Abstract: A bone anchor device for attaching connective tissue to bone comprises a disk adapted for insertion into a portion of bone to which the connective tissue is to be attached. The disk is movable between a bent orientation for presenting a smaller cross-section and an expanded orientation for presenting a larger cross-section. The bent orientation is utilized for inserting the disk through a small hole into a region of cancellous bone beneath the cortical bone layer, after which the disk is actuated to its expanded orientation so that it will be permanently anchored in the cancellous bone, as it will be too large to return proximally through the hole in the cortical bone layer. Two embodiments are disclosed. In a first embodiment, the disk is initially formed in the expanded orientation, of spring steel. In a second embodiment, the disk is initially formed in the bent orientation, and spring steel is not required.
