Systems, devices, and methods are provided for orthopedic implants. The implants may include a base member, such as an acetabular shell or an augment, that is configured to couple with an augment, flange cup, mounting member, or any other suitable orthopedic attachment. Mounting members include, for example, flanges, blades, hooks, and plates. In some embodiments, the orthopedic attachments may be adjustably positionable about the base member or other attachments, thereby providing modularity for assembling and implanting the device, and various securing and/or locking mechanisms may be used between the components of the implant.

A bone anchor includes an anchor member including a first material, and having a tubular section extending along a longitudinal axis, a region configured to expand radially outwards from the longitudinal axis, and a bone engagement structure projecting from at least a portion of the expandable region of the tubular section, and a core member including a second material, and configured for insertion into and connection to the anchor member. When the core member is in the anchor member and is actuated relative to the anchor member, the tubular section is adjustable between a first position where the expandable region of the tubular member has a first length and a first maximum diameter, to a second position where the expandable region of the tubular member has a length shorter than the first length and a maximum diameter greater than the first maximum diameter.

An anchor device for use in sacroiliac joint stabilization comprises a housing having a bore, one or more apertures, and a threaded outer surface, one or more engagement members at least partially disposed in the housing, where at least one of the one or more engagement members is movable between a retracted position and an extended position such that, when the at least one of the one or more engagement members is in the extended position, the at least one of the one or more engagement members extends through at least one of the one or more apertures, and where, when the at least one of the one or more engagement members is in the extended position, the at least one of the one or more engagement members is configured to engage a cortical wall of a sacrum bone.

Implantable devices for dynamic interconnection between bones, and especially between vertebrae. Some devices include tethering heads that are independent of the bone connecting member (fastener, plate, hook, loop). The devices provide for various types of manipulation of a flexible connection such as a tether, such as by providing an aperture through which the flexible connection is passed and guided, or a post to which a loop of the flexible connection can be attached, or a groove in which a loop of the flexible connection can be placed.

In general, devices, systems, and methods for driving an anchor into bone are provided. In one embodiment, a surgical tool is provided that includes a driver tool with a handle and an elongate shaft. A resistance element is disposed within the handle. An inner portion of an anchor is retained on a distal end of the elongate shaft, and a guidewire extends between the resistance element and an outer portion of the anchor that is in bone. As force is applied distally to the handle, the guidewire pushes the anchor into the bone before overcoming force of the resistance element and thereby allowing the inner portion of the anchor to be driven into the outer portion of the anchor.

This disclosure is directed to surgical fixation devices (e.g., staples, screws, etc.) which are able to bring bone fragments into close proximity with each other, generate a compressive load, and maintain that compressive load for a prolonged period of time while healing occurs. The surgical fixations devices are manufactured from a shape memory material (e.g., a material capable of exhibiting superelasticity and/or a temperature-induced shape change).

A flexible tubular member for guiding insertion of instrumentation to a bone screw affixed within bone includes a tubular body that is flexible, constructed of textile material, and defines a longitudinal axis. The tubular body also defines a proximal end and a distal end opposite each other along the longitudinal axis. The tubular body further defines a guide channel that extends from a proximal opening at the proximal end to a distal opening at the distal end. An attachment member is located at the distal end of the tubular body and is configured to couple the distal end to a proximal portion of the bone screw. The attachment member has an annular shape around the guide channel and is configured to expand responsive to a predetermined tensile force applied to the tubular body for decoupling from the bone screw

Systems, devices, and methods are provided for orthopedic implants. The implants may include a base member, such as an acetabular shell or an augment, that is configured to couple with an augment, flange cup, mounting member, or any other suitable orthopedic attachment.

Apparatus and methods are provided for the approximation of two bones, the apparatus including a first anchor that is rotationally driven into a first bone by a second bone anchor, which receives driving torque from a driver tool. After the first anchor is secured in the first bone, the second anchor is disengaged from the first anchor but remains connected to the first anchor by a flexible link of a designed length. The second bone anchor is secured in the second bone and has provisions to be lengthened or shortened to adjust the overall length of the implant, thereby adjusting the approximation between the two bones.

A compression force magnifier including a vertical axis through a body and a proximal surface of the body sloped at a predetermined angle relative to the vertical axis. A flat distal surface of the body is disposed opposite the proximal surface. A bore is disposed through the body from the proximal surface through the distal surface. The body is connected to an arm having a connection opening configured to allow connection of the body to a bone plate. The connection opening has a connection axis spaced from the vertical axis.
