The present disclosure is directed to temporary antimicrobial-eluting cement spacer implants, and assemblies, kits, and methods for forming the same. Particularly preferred disclosures are to modular spacers, assemblies, and kits, as well as methods of manufacturing the same, where the modular nature of the spacer permits the selection of specific desired length spacers, as well as specific selection of antimicrobial compounds and dosages, along with the components and processes for forming the same.

Temporary antimicrobial cement spacer, assembly, kit, and method of manufacture

A retrograde intramedullary nail for insertion in the medullary canal of a femur includes a body that is elongate and defines a leading end and a trailing end spaced from each other at a length sufficient to extend from an intercondylar region at least to a subtrochanteric region of the femur. The body further defines a leading portion that extends to the leading end. The leading portion defines at least one locking hole configured to receive a fixation member. The at least one locking hole defines a central hole axis that is oriented to extend through the neck and head of the femur.

A system for penetrating the lateral cortex of a long bone includes a tubular cortex penetrator having an inner surface and an outer surface, a proximal end, and a distal end comprising a beveled cutting edge configured to penetrate the lateral cortex. A guide wire is configured to pass over the tubular cortex penetrator, and a guide sleeve is configured to surround the outer surface of the tubular cortex penetrator. A hollow extraction screw with an axial bore, a proximal end, a distal end, and a threaded cutting edge is configured to pass through the axial bore of the hollow extraction screw; and the hollow extraction screw is configured to retract into a distal end of a bore through the tubular cortex penetrator.

A support rod for a hollow, flexible torque transmitting shaft for treating a bone includes support and flex portions. When the rod is received at a desired position within the shaft, the support portion extends through a first non-bendable portion of the shaft. An outer diameter of the support portion substantially corresponds to an inner diameter of the shaft to support the first portion. When the support rod is received at the desired position, the flex portion extends through a second bendable portion of the shaft. The flex portion includes a holding portion having an outer diameter substantially corresponding to an inner diameter of the second portion and a gap portion having an outer diameter reduced relative to the outer diameter of the holding portion to form an annular gap between the gap portion and an inner surface of the holding portion.

A guide sleeve for use in anchoring a fixation member to an intramedullary nail and to bone includes a sleeve body that is elongate along a central axis and has an internal surface that defines a bore extending along the central axis to a distal end of the sleeve body. The sleeve body also defines a plurality of guide channels that are each recessed radially outwardly from the internal surface and each include a helical proximal portion and a linear distal portion that extends from the helical proximal portion toward the distal end. The linear distal portion is parallel with the central axis. The guide channels are configured to receive respective complimentary followers of an instrument for driving the fixation member through the bore and subsequently through the intramedullary nail and into the bone.

Guide sleeve for fine axial adjustability of a fixation member, and related systems and methods

A system for treating a bone includes an insertion device for an intramedullary nail. A first end includes a channel extending therethrough so that, when the insertion device is coupled to an intramedullary nail, the channel of the device is aligned with and in communication with a channel of the nail. The system also includes a guide sleeve extending from a proximal end to a distal end and including a first bend extending along a portion of a length thereof so that a longitudinal axis of a distal portion of the sleeve is angled with respect to a longitudinal axis of a remaining portion of the sleeve. In an operative position, the distal end of the sleeve is inserted into the channel of the device and the remaining portion of the sleeve extends toward a lateral side of a bone being treated.

Flexible shaft guide tube

A bone fixation device includes an elongated body (a) having a first channel extending therethrough and configured for insertion into a bone, a first opening (b) formed on a first side wall of the body, the first side wall facing a lateral direction when implanted in a target orientation within the bone and a second opening (c) formed on a second side wall of the body opposite the first opening. A second channel (d) extends through the body from the first opening to the second opening and is dimensioned to permit insertion of an implant therethrough. A first bump (e) is positioned about a periphery of the first opening at a location at which a stress concentration would be a maximum if no such first bump were formed. The first bump is dimensioned to diffuse a concentration of stress about the periphery due to forces applied thereto by an implant extending through the second channel.

Bump cut on hole edge

A lever for grasping bone tissue includes a shaft defining a channel and having a proximal end and a distal end, a claw member disposed on the distal end of the shaft for holding the bone tissue, and a rod threadably received in the channel and having a proximal end and a distal end. Rotation of the rod with respect to the shaft causes the rod to move substantially axially with respect to the shaft to selectively position the distal end of the rod with respect to the claw member. The lever may further include a locking member to allow the rod to slide axially with respect to the shaft. Various other features which improve the functioning of the lever may be provided separately or in combination.
