A bone fastener driver assembly with a bone fastener retention feature has an outer sleeve, a handle fixed to said outer sleeve and an inner shaft. The inner shaft has a distal end with a torque driving tip. The inner shaft is coupled to the handle and axially movable relative to the outer sleeve from a proximal disengaged position to a distal engaged position. The outer sleeve has a bone fastener retaining distal end configured to lock into an internal groove or undercut of a bone fastener screw head when the inner shaft is axially moved from the proximal disengaged position to the distal engaged position to lock the bone fastener to the driver and upon a return movement of the inner shaft to the proximal disengaged position to unlock and release the driver from the bone fastener screw head.

An intramedullary (IM) nail insertion assembly includes an IM nail extending longitudinally from a proximal end to a distal end. A proximal portion of the IM nail has an internal threading. The IM nail insertion assembly also includes a connecting screw extending longitudinally from a proximal end to a distal end. A distal portion of the connecting screw has an external threading for engaging the internal threading of the TM nail. One of the proximal portion of the IM nail and the distal portion of the connecting screw has a feature to resist a disengagement of the proximal portion from the distal portion.

A surgical fastener includes a cannulated collapsible fastening body having a trailing end and a leading end and defining a passage extending from the trailing end to the leading end, and a pin having a non-threaded shaft at least partially disposed within the passage and an enlarged tip. A method of using the surgical fastener includes engaging an end of a driver with a recess in a head of the surgical fastener, including inserting an extension at the end of the driver into the passage, and inserting the fastener into a bore in a bone during which the extension of the driver abuts a trailing end of the shaft of the pin to prevent the pin from moving in a direction from the leading end to the trailing end relative to the fastening body.

Systems, assemblies, and methods are provided herein for fastening of one bone to another bone using one or more sutures. The features herein enable such fastening with a more accurate strength, and which can be more easily fastened in-situ.

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.

Orthopedic fixation devices and methods of installing the same. The orthopedic fixation device may include a coupling element and a bone fastener, whereby the bone fastener can be loaded into the coupling element through the bottom of a bore in the coupling element and a retention member is configured to allow polyaxial rotation of the bone fastener and also to lock the bone fastener in place upon application of a force on a saddle and clamp in the coupling element.

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.

An endcap for engaging a proximal end of an intramedullary nail. The endcap includes a body extending from a first end to a second end and configured to engage a channel of an intramedullary nail. The endcap also includes a head portion at the first end of the body. The head portion includes a recess sized and shaped to receive a driving element of a drive shaft. The recess includes elastic tabs extending radially toward a central axis of the recess to engage and retain a driving element received therein.

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.
