    Abstract: A spinal alignment system for interconnecting vertebral bodies is disclosed. The system includes a bone screw polyaxially connected to a seat. The seat includes a top opening, a first rod receiving portion and a second rod receiving portion, a first rod channel and a second rod channel. The system is implanted into a first vertebral body. A first rod is introduced to the seat through the top opening in a first orientation and connected to the first rod receiving portion. A second rod is introduced to the seat through the top opening in a first orientation and connected to the second rod receiving portion. The first and second rods are each moved into a second orientation such that the rods project through the first and second rod channels, respectively. The rods are capable of polyaxial movement with respect to the seat for landing the opposite ends of the rods in adjacent seats of screw systems implanted in other vertebral bodies. A closure mechanism that is configured to lock the polyaxial motion of the rods with respect to the seat and to lock the polyaxial motion of the bone screw with respect to the seat simultaneously or independently is provided. The seat is connectable to a cannula for delivering the first and second rods into the first seat in a percutaneous, minimally invasive procedure.

    Abstract: An inserter for implanting an intervertebral spacer into a spinal disc space is disclosed. The inserter comprises a jaw assembly connected to a shaft assembly that is connected to a handle assembly. The user operates the handle assembly to open and close the jaw assembly to thereby connect to and release from the intervertebral spacer. Furthermore, the handle assembly is operable to lock and unlock rotation of the jaw assembly while still connected thereto to permit angulation of the jaw assembly relative to the shaft assembly without losing hold of the intervertebral spacer.

    Abstract: An apparatus and method of use directed towards protective and supportive hole caps for prosthetic implant devices are disclosed. The present hole cap supports a prosthesis and provides a physical barrier between the prosthesis and underlying bone matter. In a preferred embodiment, the hole cap includes at least one compression spring formed along the perimeter of the cap. The compression spring maintains the hole cap within a counter-bored hole after the hole cap is inserted within the counter-bored hole. In accordance with the present invention, the compression spring deflects slightly towards the center of the hole cap when the cap is inserted within the counter-bored hole. The compression spring provides sufficient compression force against the sidewalls of the counter-bored hole to thereby hold the hole cap in place within the hole. The counter-bored hole is preferably shaped to snugly receive the outer perimeter of the hole cap. Alternative configurations are disclosed for maintaining the hole cap within an associated hole formed in the implant. The hole caps are used for covering holes in implants affixed to a patient's body with or without the use of bone screws. The hole caps prevent the flow of unwanted debris into the counter-bored hole and into the patient's underlying bone matter.

    Abstract: A locking surgical tool handle system. The invention includes a surgical tool handle that has an elongated body portion with a pistol-type grip. The front end of the handle body has a tool retaining structure comprising a contoured engagement face and a movable tension bar with an engagement end. Projections on the engagement end of the tension bar fit within a receiving channel of a surgical tool, such as a broach or rasp. A locking mechanism is provided within the handle body, and is implemented with pivotable links attached to the tension bar. The locking mechanism has an unlocked position in which the engagement end of the tension bar is spaced away from the engagement face of the handle body, and an over-center locked position in which the engagement end of the tension bar is retracted toward the handle body. When the tool handle is placed in its locked position, the engagement end of the tension bar pulls an attached tool into tight contact with the engagement face of the handle body.

    Abstract: A femoral stem prosthesis including a stem tapering from a proximal end to a distal end, and having a primary zone of taper and a secondary zone of taper. The secondary zone of taper, located at the distal end of the stem, has a larger angle of taper than that of the primary zone of taper, but substantially less than the taper in prior art stems. In the secondary zone of taper, the stem gradually tapers away from the femoral bone to avoid a sudden change in stress level in the bone at the distal stem tip, thus avoiding the incidence of thigh pain. The stem of the inventive prosthesis preferably includes longitudinal channels to increase its flexibility and preferably has a trapezoidal cross-sectional geometry to resist rotational forces and to provide multi-plane stability within the femur, thereby providing effective stress transfer to the femur.
