In accordance to one aspect of the present disclosure, a driver for a bone screw is provided that includes an inner shaft and a distal drive head of the inner shaft. The drive head is configured to fit in a drive recess of a bone screw to form a mating connection therewith. The driver further includes at least one outer, resilient locking member shiftable along the inner shaft from a proximal, unlocked position to a distal, locked position. The resilient locking member has a locking portion that contacts and is urged outwardly by a proximal ramp surface of the drive head as the locking member shifts distally from the unlocked position to the locked position to secure the bone screw onto the drive head.

A hybrid radiolucent screw having radiopaque components and radiolucent components, which collaboratively define a tip of the screw and a head of the screw. In this manner, distortion is minimized during fluoroscopy or radiography of the screw while visualization of the screw and surrounding area is enhanced.

A torque enhancing device that includes a torque contact body having one or more torque driver and/or recessed recipient torque contact surface configurations, inclusive of those in a multi-tier arrangement. The body having a Z-axis depth or thickness, and each of the torque contact surface configurations includes a pair of X-axis extending torque contact side walls that are spaced apart by L1 along a Y-axis, and a pair of Y-axis extending torque contact side walls that are spaced apart by L2 along the X-axis, with at least one of the one or more torque contact surface configurations having four concave contoured surface portions positioned between respective adjacent most ends of the X-axis extending torque contact side walls and the Y-axis extending torque contact side walls, and a length ratio L2/L1 is less than 1 as to provide a torque enhancement contact surface configuration. A method of driving such as insertion or removal of the recessed recipient such as in fastener form is included.

A driver for engaging an endcap of an intramedullary nail. The driver includes a handle extending along a longitudinal axis of the driver from a proximal end to a distal end. The handle having a handle channel extending longitudinally therethrough. The driver also includes a shaft extending through the handle channel from a proximal end to a distal end along the longitudinal axis. The shaft having a shaft channel extending longitudinally therethrough. The distal end of the shaft extends distally from the handle. The distal end of the shaft forms a driving element to be inserted into a head portion of the endcap. The driver further includes a retention pin slidably received in the shaft channel. The retention pin extends also extends along the longitudinal axis. The distal end of the retention pin is configured to reversibly lock the shaft to the head portion of the endcap.

A bone screw insertion device, comprises an outer sleeve extending from a proximal end to a distal end and including a channel extending therethrough and a driving member extending longitudinally through the channel of the outer sleeve from a proximal end to a distal end configured to engage a driving recess of a bone screw, the outer sleeve movable relative to the driving member between a first position in which the distal end of the outer sleeve extends over and covers a proximal portion of a bone screw engaged with the driving member, to a second position in which the distal end of the outer sleeve is longitudinally aligned with a proximal end of a bone screw engaged with the driving member.

A device, including a body including a torque transfer section and a torque receiver section, wherein the device is a bone conduction hearing prosthesis bone fixture implant insertion device configured to interface with an interior of the bone fixture, and the device is made of a same class of materials at the torque transfer section and the torque receiver section and section(s) that interface with the bone fixture.

A bone plate having at least one screw hole adapted to receive a bone screw, a blocker having a blocking end for blocking a bone screw from further backout of bone the blocker being predisposed in a blocking position wherein the blocking end at least partially overlaps a portion of the screw hole, the blocker being moveable from the blocking position by contact with the bone screw during insertion of the bone screw into the screw hole, and a blocker fixation element having an open orientation at which the blocker can move from the blocking position and a closed orientation preventing substantial movement of the blocker from the blocking position. The blocker fixation element cannot be moved to the closed orientation unless the screw head passes the blocker, thereby revealing that the blocker fixation element is in position to prevent substantial movement of the blocker.

The present invention relates to a screw drive having integrated torque protection, wherein two screw drives are incorporated in a screw head, one drive being an internal polygonal drive and the second drive being an internal multilobular drive. In addition, the invention relates to a screw having a screw drive.

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.

The present disclosure relates to a spinal implant. The spinal implant may be used for lateral insertion into an intervertebral disc space. For example, the spinal implant may include a spacer body to which a plate is fixed. The intervertebral spacer body may include a pair of opposite sides having a pyramid-shaped teeth to fuse to bone. The plate defines at least one upper and lower borehole that each receives a screw. Each screw attaches the plate to a vertebral body between which the intervertebral spacer body is inserted. The boreholes may include locking threads that are adapted to lock the screws into place by engaging complementary locking threads of head of the screw.
