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.

A spinal construct includes a coupling member including a first mating surface engageable with an existing fastener implant. The existing fastener implant defines a cavity configured for disposal of an existing spinal rod implant. A connector is engageable with the existing fastener implant and has a rod extending therefrom. A locking member is engageable with a second mating surface of the coupling member. Systems, surgical instruments, implants and methods are disclosed.

A bone fixation clamp includes first and second clamp members, a stud, and a locking nut. The first member extends along a curve corresponding to an outer surface of a first portion of bone and includes an opening extending therethrough along an axis extending adjacent to the bone. The second member extends along a curve corresponding to an outer surface of a second portion of bone. The stud is receivable within the opening of the first member. The nut includes a threaded channel threadedly engaging a portion of the stud so that, when the first and second members are in the operative configuration, the nut is threadable over the stud to fix the first and second members over bone. The nut includes an anti-loosening feature which, when the nut is threaded over the stud, results in an interference with threading along the stud.

A bone repair system, kit and method for percutaneous repair of a bone segment containing a first bone segment and a second bone segment in a patient, each bone segment having a drill hole. The system comprises a longitudinal member configured to contact the first bone segment and the second bone segment and having at least one opening and cleats on the side adapted to contact the first bone segment and the second bone segment; a first fastener assembly configured to be disposed through the opening of the longitudinal member to hold the longitudinal member in place through the opening and the hole in the first bone segment; and a second fastener assembly configured to be disposed through the opening of the longitudinal member to hold the longitudinal member in place through the opening and the hole in the second bone segment.

Methods and devices for treating spinal deformities are provided. In one exemplary embodiment, a low-profile spinal anchoring device is provided for receiving a spinal fixation element, such as a tether, therethrough. The device generally includes a staple body that is adapted to seat a spinal fixation element, a fastening element for fixing the staple body to bone, and a locking assembly for coupling a spinal fixation element to the staple body. In one embodiment, the locking assembly includes a washer that is adapted to couple to the staple body such that the spinal fixation is disposed therebetween, and a locking nut that is adapted to engage the staple body to mate the washer to the staple body.

A locking cap for a fracture fixation system may include a cap body that extends along a longitudinal axis between a proximal end and a distal end. An external thread extends around at least a portion of the cap body. A passage extends inside the cap body from the distal end toward the proximal end. An internal thread extends about a periphery of the passage along at least a portion of a length of the passage.
