摘要： A high strength fastener for bone fractures. This fastener consists of two members, a male and female. The male member has external machine screw threads that screw into matching internal threads in the female member at a predictable torque so that the force of fixation exerted upon the bone can be approximated by the installer. Because of the effective length of the threads, this fastener is easily adjusted to the proper length without cutting. Both members have a smooth shoulder region proximal to the heads and this shoulder region presents a low-stress bearing surface to each cortical wall. Each member has a head that fits rigidly into an installation tool providing for ease of insertion and fastening in the patient with minimal invasion and little periosteal stripping. Each head has a semi-spherical face that articulates with matching washers and plates, thus allowing the washer to assume the plane of the surrounding bone therefore distributing the load over a greater area.

摘要： A bone plate comprises a base plate having at least two screw holes and at least two bone screws capable of securing the bone plate to a bone by insertion through the screw holes into the bone. The bone screws have heads shaped to toggle within the screw holes. A retaining plate is provided that is fixedly attachable to the base plate. The retaining plate covers at least a portion of each of the bone screws. The retaining plate and base plate each contain set screw apertures. A set screw is provided to retain the retaining plate in place over the base plate by screwing the set screw through the set screw apertures in the retaining plate and base plate. This design prevents the bone screw from backing out from the bone once screwed in through the base plate.

摘要： A combination driver and bone screw assembly comprising a screw shank with a uniform diameter threaded portion, an unthreaded portion with a outwardly tapered end and a driving end portion of substantially wedge shaped configuration which can be engagably seated in a wedge shaped notch seat of a driver member. The driver member comprises a body, a drive head defining a wedge shaped notch seat secured to the body forming a shoulder and a drive collar mounted around the drive head and seated on the shoulder.In operation a bore is drilled in the patients bone with the top portion of the bore having a tapered geometry which widens from the diameter of the bore. The bone screw driving end portion is placed in the wedge shaped notch seat of a driver member and a drive collar is mounted around the driver drive head and engages the shoulder. The driver member is rotated driving the bone screw into the previously cut bore in the patients bone until the tapered surface of the bore engages the tapered undercut surface of the screw.

摘要： Apparatus for and methods of inserting implants are disclosed wherein the apparatus includes a handle portion and a body portion attached to the handle portion and defining a longitudinal axis. The body portion includes an outer tubular member fixed relative to the handle portion for rotation therewith about the longitudinal axis. The outer tube member has first implant engaging structure adjacent a distal end. An inner tubular member is disposed at least partially within the outer tubular member and is mounted for longitudinal motion relative to the outer tubular member. Second implant engaging structure is positioned adjacent a distal end of the inner tubular member. The body portion further includes an inner shaft, coaxially mounted at least partially within the inner tubular member for independent rotation relative to the inner and outer tubular members, the inner shaft having third implant engaging structure adjacent a distal end. In a method for inserting an implant having a hollow portion with a closed distal end and a removable cap, the first, second and third implant engaging structures are attached to the implant with at least one of the engaging structure attached to the removable cap and another of the engaging structure attached to the hollow portion. The implant is preferably preloaded with bone chips and/or bone growth inducing substances prior to attachment. Thereafter, the preloaded implant is inserted into the desired surgical location.

摘要： A bone screw screwdriver and method for securely, positively locking a bone screw to the screwdriver. The screwdriver includes an extending handle through which a drive rod is slidingly disposed. A tongue at one end of the drive rod interlocks within a groove in the bone screw. The drive rod selectively locks within the handle to positively interlock the bone screw with the screwdriver. A tab on the screwdriver engages a corresponding recess on the bone screw to prevent rotation and removal of the bone screw from the screwdriver.

摘要： An orthopedic screw extractor device including a shaft, an end portion about a first end of the shaft for securing to a handle, and a screw extracting tip about a second end of the shaft opposite the first end. The screw extracting tip further includes a generally frustoconical shape having a side at an angle of about 5 to 15 degrees relative to a longitudinal axis of the screw extracting tip. The screw extracting tip further includes first, second and third screw threads and first, second and third flutes circumferentially spaced about the screw extracting tip and extending across an entire length of the screw extracting tip. Each of the screw threads has a lead of about 0.07 to 0.12 inches, a pitch of about 0.02 to 0.04 inches, a thread angle of about 40 to 50 degrees, and a depth of about 0.01 to 0.02 inches.

摘要： A spinal facet bone screw and minimally invasive surgical method of implanting a facet screw to stabilize the spine are provided. The facet screw includes an elongated body portion having a head, a threaded portion and a distal threadless portion. A pair of flutes formed in the elongated body extends from the distal end across the threadless portion and into the distal end of the threaded portion. The flute creates a self-tapping cutting surface that includes a heel edge that is curved with respect to the outer surface. The method of implantation comprises making a minimally invasive incision on the side of the midline contralateral to the target facet joint and delivering the screw across the interspinous process using the adjacent spinous processes as guideposts. The facet screw system fixes juxtaposed facet articular processes to enhance spinal fusion and stability and the method provides for accurate, repeatable and easy implantation.
