In a rod fixation system of the type used to treat various spinal conditions, the same fastener is used to lock both a polyaxial screw and a rod in position. A spinal correction device according to the invention, adapted for use with a rod and a polyaxial screw having a ball-shaped head and a threaded end, comprises a head-body and a cap. The head-body includes a lower internal cavity to receive the ball-shaped head of the screw, an upper bore to receive a fixation rod therethrough, and an upper end configured to receive the cap. The head-body and the cap are configured such that a first rotation of the cap locks the polyaxial screw in position, and a second rotation of the cap locks the rod in position. In the preferred embodiment, the head-body includes one or more gaps to facilitate flexion of the head-body as a rotational torque is placed on the cap. The gap or gaps may be horizontal, vertical or other angles relative to the axis of the entrapped rod.

A surgical screw that includes a body portion that facilitates bone in-growth from a bone in which the screw is mounted so as to stabilize the screw in the bone. The body portion can have various configurations for facilitating bone in-growth, such as indentations, a roughened surface, such as by acid etching or abrasive media blasting, specialized coatings, such as hydroxyapetite, sintered beads, machined channels, etc. Because the body portion of the screw facilitates bone growth, the screw will be more firmly mounted to the bone so as to have a greater integrity in response to movement of the bone. The type of surgical screw can be any surgical screw that will benefit from being better anchored in bone, such as pedicle screws, long bone screws, cervical fusion screws, tendon anchoring screws, etc.

A system for performing bone arthrodesis includes an implant for bone arthrodesis and a bone fastening device. The implant includes a fastener with an elongated shaft having a head at one end and a bone-piercing point at the opposite end. A first washer has structure for engaging the head of the shaft so as to be polyaxially pivotable with respect to the head. A locking member has structure for engaging the shaft. The locking member can have a second washer pivotally engaged thereto. The bone fastening device can include an elongated cannula with a collet for detachably engaging the first washer and for advancing the first washer. Structure is provided for engaging the fastener and for advancing and rotating the fastener through the collet and through the first washer. The bone arthrodesis device further includes a lower end portion extending from the cannula. The lower end portion has structure for detachably engaging the locking member.

A suction retractor including an elongated tube that is operable to be inserted through a tubular retractor used in minimally invasive surgical procedures. One end of the tube is coupled to a handle having a chamber and the other end of the tube is coupled to a curved retractor portion, where the retractor portion allows the surgeon to hold back various anatomies during the surgical procedure. Thus, the suction retractor provides two functions that may otherwise require two different instruments. The retractor portion includes a series of parallel groves that allow liquids, such as blood, to flow along the retractor portion and into a suction port at the end of the tube. A suction device can be coupled to an outlet port in the handle that causes the blood and other surgical material to be sucked through the tube and out of the handle.

606279

A method for attaching a laminar plate to a vertebra during spinal surgery, especially minimally invasive spinal surgery, to reconstruct the lamina of the vertebra after it has been removed during the surgery and prevent bone re-growth material from entering the spinal canal. The laminar plate can be coupled to, or proximate to, and between a facet and the spinous process by screwing the plate to the bone.

A minimally invasive surgical access device that allows access to a pathology being treated while significantly reducing the risk of damaging anatomical structures proximate the pathology. The access device includes a base portion having a central bore extending therethrough, and retractor blades pivotably mounted to the base portion. An insertion handle is coupled to the base portion to thread the retractor blades into the patient. The insertion handle is removed from the base portion, and a core hollow screw is threaded into the base portion to separate the retractor blades to gain access to the pathology through the hollow screw.

A cutting device is provided for making subcutaneous incisions. The cutting device has a housing forming a handle. A tubular blade sub-assembly extends from the housing. A trocar passes through the tubular blade sub-assembly and is configured to be positioned in a first active position, with a tip of the trocar extending beyond the end of the tubular blade sub-assembly and a second retracted position where the tip of the trocar is held within the end of tubular blade sub-assembly.

A method for providing disc regeneration that includes at least partially restoring disc height using a vertebral disc annular fibrosis tensioning and lengthening device, and then injecting a biologic substance, such as stem cells, into the disc that differentiate into chondrocytes and/or notochordal cells that facilitate disc regeneration. Once the biologic substance has regenerated the disc, it may be possible to remove the vertebral disc annular fibrosis tensioning and lengthening device.
