Spinal pedicle screws are placed into vertebrae from the same approach and the same anterior, anterolateral or anterior/lateral exposure that is used for an anterior/lateral spine operation, during the same surgical procedure as the spine operation. Once the anterior spine operation is complete, pedicle screws areplaced into the vertebrae with a front-to-back trajectory, in a generally anterior, lateral, anterolateral, or contralateral trajectory, avoiding the need for a second operation exposing the posterior spine.

An implant for the stabilization and/or fusion of the sacroiliac joint has an elongated, spiraled exterior shape. The implant has a conically tapered inner core with a passage opening which extends in the axial direction along a central longitudinal axis over the entire axial length of the implant and ribs which run outward in a radial manner at least sectionally and which are arranged on the inner core and extend helically in the axial direction around at least one section of the inner core.

The invention involves a device and method for acquiring bone marrow aspirate. The system includes an elongated cannulated fastener having a threaded end for attachment to a bone. The threaded portion includes a directional aperture sized to allow marrow to be drawn into the cannula. The directional aperture also allows the user to direct the aperture in a desired direction within the bone for acquisition of the marrow. The distal end of the cannulated fastener includes a connector which may be in the form of a Luer lock to allow vacuum to be applied to the cannula for drawing the marrow into a syringe or the like.

A surgical instrument is connectable to a bone anchor insertion device having a drive shaft that defines a coaxial channel for receiving a needle therethrough. The instrument includes a handle portion configured to be coupled to the drive shaft in a rotationally fixed manner to transmit torque to the drive shaft, a needle holder configured to hold a needle and movable axially relative to the handle portion, an actuator rotatable relative to the handle portion, and a transmission member connectable to the needle holder and movable axially relative to the actuator and comprising a first advancement surface engageable with a second advancement surface of the handle portion to convert rotational movement of the actuator into axial movement of the needle holder relative to the handle portion for axially advancing and retracting a needle held by the needle holder relative to the handle portion.

A pivotal spinal fixation system includes bone anchors comprising capture portions having a partial spherical shape with flat side surfaces, multi-planar receivers with continuous interior circumferential engagement surfaces proximate their bottom openings, and uni-planar receivers with non-continuous interior circumferential engagement surface proximate their bottom openings. The system also includes circular retainers, each having a non-continuous outer circumferential surface configured for non-pivotal engagement with the interior circumferential engagement surfaces of both the multi-planar receivers and the uni-planar receivers, and an inner surface configured to expand and contract around the capture portion and flat side surfaces of a bone anchor so as to capture the bone anchor within a multi-planar or uni-planar receiver. The system provides for pivotal motion of the bone anchors in any of a plurality of angular directions relative to the vertical centerline axes of the multi-planar receivers while limiting pivotal motion to a single pivot plane relative to the vertical centerline axes of the uni-planar receivers.

A plate for fracture fixation is provided including a plurality of individually adjustable heads and various features to achieve: a.) superior fixation of the plate to osteoporotic diaphyseal bone; b.) improved visualization of the fracture line; c.) intraoperative adjustability to achieve better contact of the plate and the bone; d.) reduced risk of post-surgery tendon rupture; d.) improved fixation of small volar marginal fragments and, e.) improved targeting and fixing of particular fractured bone fragments.

A sacroiliac joint screw has a screw body having a head and a treaded shank with a self-drilling cutting tip. The screw body is cannulated and configured to receive a Steinmann pin for the purpose of a minimally invasive approach (MIS) for delivery to the sacroiliac joint (SI) while minimizing soft tissue damage. The self-drilling cutting tip creates a pilot hole. The threaded shank has a plurality of spiral cutting flutes, the spiral cutting flutes extend along a length of the threaded shank and are configured to provide a constant self-tapping feature. A plurality of bone harvesting windows are positioned in the spiral cutting flutes and are configured to pull in bone as the screw is advanced into the joint.

A surgical screw for fixation into bone or soft tissue. The surgical screw includes a cannulated body having a proximal end and a distal end. The distal end of the cannulated body has a tapered tip and a plurality of threads extend around the exterior of the cannulated body. An introducer extends distally from the tapered tip and has a diameter (which can be variable or constant) which is less than a diameter of the tapered tip. The surgical screw is cannulated such that a channel extends through the body from the proximal end to (and sometimes through) the distal end.

A bone fixation system includes a length of suture, a screw, a tensioning tab, and an anchor. The length of suture has a first end and a second end. The screw comprises an elongated shaft having a threaded external surface, wherein the screw has a distal end, a proximal end, and an internal surface defining a passageway within the screw extending between the distal end and the proximal end, wherein the passageway is configured to receive the length of suture. The tensioning tab is affixed to a section of the length of suture. The anchor is configured to secure the first end of the length of suture adjacent to the proximal end of the screw.

Threaded sacro-iliac joint stabilization (e.g., fusion, fixation) implants and methods of implantation and manufacture. Some implants include a threaded distal region, an optionally threaded central region, and an optionally threaded proximal region. The distal, central, and proximal regions have lengths such that when the implant is laterally implanted across a SI joint, the distal region can be positioned in a sacrum, the central region can be positioned across an SI-joint, and the proximal region can be positioned in an ilium.
