Bone implants, including methods of use and assembly. The bone implants, which are optionally composite implants, generally include a distal anchoring region and a growth region that is proximal to the distal anchoring region. The distal anchoring region can have one or more distal surface features that adapt the distal anchoring region for anchoring into iliac bone. The growth region can have one or more growth features that adapt the growth region to facilitate at least one of bony on-growth, in-growth, or through-growth. The implants may be positioned along a posterior sacral alar-iliac (“SAI”) trajectory. The implants may be coupled to one or more bone stabilizing constructs, such as rod elements thereof.

Various embodiments of a pedicle screw assembly disclosed herein include a pedicle screw configured for engaging with bone tissue. The pedicle screw includes a body defining a plurality of channels through the body of the screw and in communication with a plurality of respective distal openings defined along the screw body. The pedicle screw assembly further includes an anchor defining a plurality of anchor members which are configured to be received at least partially through the plurality of channels and the plurality of respective distal openings to further engage the pedicle screw to the bone tissue.

Systems and methods for treating a vertebral body. An intravertebral implant includes an anterior end element and a plate comprising a planar bearing surface. The plate may be exactly two plates movable in only a cranio-caudal expansion plane. A pedicle fixation is coupled to the intravertebral implant and includes a hollow sleeve. The pedicle fixation is configured to be secured to the pedicle to control an insertion depth of the intravertebral implant within the vertebral body. A central traction member is movably disposed within the hollow sleeve of the pedicle fixation to deploy the planar bearing surface(s). The central traction member may be rotatable within the hollow sleeve. An expansion instrument may move the central traction member relative to the pedicle fixation. The intravertebral implant may be locked relative to the pedicle fixation in six degrees of freedom.

A surgical fastener provided with a curved cutter, an anterior wedge-like tip and a surgeon facing end. Among other things, the surgical fastener's cutter can cut bone or other tissue.

Devices and methods are disclosed for orthopedic uses, such as treating and compressing a broken bone. An implantable device may be provided with an elongate body, a head region, a bone engagement part such as an anchor region or threads, and a dynamic compression portion in either a first axially compact configuration or a second axially elongated configuration and configured to transform between the first axially compact configuration and the second axially elongated configuration.

The bone screw with internal extendable is a bone screw with an internal, extendable tang. The tang—part of a tang system—is concealed within the body of the screw until after placement. After the screw is threaded into the bone, the internal tang system is pushed out of the bone screw body, forcing one or more tangs to extend out of the body and into the bone. A driver allows the user to control the different steps of insertion, including converting rotational motion of a knob into linear motion of a rod, the rod moving through the screw body to force the tang to exit the bone screw body. The one or more tangs preferably exit the bone screw body at a tang exit portal formed by one or more tang exit guide surfaces.

A bone rivet is provided that may be used as an alternative to a bone screw for bone fixation. The bone rivet includes a head and a threaded shaft that can be expanded upon installing the bone rivet into bone. A channel extends through the bone rivet and is shaped corresponding to a bulb of a mandrel used for installing the bone rivet. A first section of the channel has a smaller width than the mandrel's bulb to enable the bulb to expand the threaded shaft and a second section is sized to have a greater width. The installation process eliminates the task of rotating a typical bone screw during its installation. The threaded shaft also includes a cutting flute, which cuts a thread path for the threaded shaft into the bone thereby reducing the amount of torque needed to rotate and remove the bone rivet from bone.

Systems, devices, and methods are provided for securing soft tissue to bone. One exemplary embodiment of a surgical soft tissue repair device includes a snare assembly coupled to a soft anchor in which the soft anchor has a first, unstressed configuration that can be used to insert the anchor into bone and a second, anchoring configuration that can be used to fixate the anchor in the bone. The snare assembly can be configured to actuate the anchor from the first configuration to the second configuration, and it can also be used to engage and approximate tissue by drawing the tissue closer to the anchor fixated in the bone. The snare assembly can be used in conjunction with a number of different anchor configurations, and other exemplary systems, devices, and methods for use with soft tissue repair are also provided.

A tissue fixation system is provided for dynamic and rigid fixation of tissue. A fastener connected with an elongate fastening member, such as a cable, wire, suture, rod, or tube, is moved through a passage between opposite sides of tissue. The fastener is provided with a groove that accommodates at least a portion of the fastening member to reduce the profile during the movement through the passage. The fastener is then pivoted to change its orientation. A second fastener can then be connected with the fastening member. While tension is maintained in the fastening member, the fasteners are secured against relative movement. This may be done by deforming the fastening member, either the first or second fasteners, or a bushing placed against the second fastener.
