摘要： A bone anchor system can comprise a fastener, a rod housing and a first directional component configured for connection to the fastener. The fastener can comprise a shaft having a shaft diameter, an anchoring projection on the shaft, and a head at an end of the shaft. The rod housing can be connected to the head of the fastener. The first directional component can comprise a first body portion having a first outer diameter larger than the shaft diameter, a first bore extending through the first body portion, the first bore sized to receive the shaft diameter, and a first locking component extending from the first body portion configured to engage the rod housing to limit movement of the housing.

摘要： A bone fastener assembly for connecting a bone to a stabilizing construct includes a connecting member, a fastener seat, and a bone fastener. The connecting member includes a connecting member axis, a first opening, a second opening, and a first spherical surface. The connecting member axis extends from a proximal end to a distal end. The first opening is adjacent the proximal end. The second opening is adjacent the distal end. The fastener seat includes a first end, a second end, a passageway, and a second spherical surface. The passageway extends from the first end to the second end along a seat axis. The second spherical surface is configured to slidably engage the first spherical surface. The bone fastener includes a shank and a head. The shank extends though the passageway. The head engages a head-mating surface of the fastener seat.

摘要： A bone fastener system can comprise a fastener and a first sizing component. The fastener can comprise a shaft that provides an anchoring footprint. The first sizing component can be configured to be connected to the shaft and can include a first anchoring feature, or circumferential bone engaging feature, to increase a size of the anchoring footprint. The first anchoring feature can comprise a sleeve that radially expands a diameter of the threaded shaft. The first anchoring feature can comprise axially extending teeth. The system can further comprise a second sizing component including a second anchoring feature to increase the size of the anchoring footprint, the second anchoring feature being different from the first anchoring feature. The second anchoring feature can expand the diameter of the threaded shaft a greater amount than the first anchoring feature. The second anchoring feature can have a length greater than the first anchoring feature.

摘要： Implementations described herein include a system that may include a deliver device, an annular anchor and an implant. The delivery device may include a distal end, a proximal and a lumen extending from the distal end to the proximal end. The annular anchor may be removably coupleable to the distal end of the delivery device. The annular anchor may be implantable at a target site in a patient via manipulation of the delivery device. The delivery device may be extendable outside the patient when the anchor is implanted at the target site. The implant may be deliverable through the delivery device to the target delivery site and implantable through the annular anchor. The delivery device may be coupled to the annular anchor to control a trajectory of the implant to the target site.

摘要： A surgical instrument suitable for preparing an intervertebral disc space includes an outer sleeve, an instrument head, an inner shaft, a handle, a universal joint, a coupling member, and a drive mechanism. The outer sleeve includes a proximal end, a distal end and a longitudinal axis. The instrument head defines a longitudinal axis and is disposed at the distal end of the outer shaft. The inner shaft is slidably disposed within the outer sleeve and includes a proximal end, a distal end and a longitudinal axis coaxially aligned with the longitudinal axis of the outer sleeve. The drive mechanism is coupled between the outer sleeve and the inner shaft and actuates the outer sleeve axially relative to the inner shaft, thereby setting an angle of the longitudinal axis of the instrument head in relation to the longitudinal axis of the inner shaft.
