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.
Bone anchors and bone anchor insertion systems are provided that enable smaller bone holes for inserting a bone anchor by eliminating the need for a cannula. Smaller bone holes may help reduce patient recovery times. The provided bone anchor includes two flexible wings extending from a base portion that splay away from the base portion's central axis at rest, though may be bent towards or away from the central axis in response to an applied force. The bone anchor includes a drive feature that enables an inserter to couple and decouple to the bone anchor. A surgeon may drive the bone anchor through a bone hole via the coupled inserter while the bone hole maintains the bone anchor in a compressed state, and may decouple the inserter when the bone anchor is properly positioned, thereby eliminating the need for a cannula.
The presently disclosed depth gauge device includes a tube with a measurement rod inserted into one end of the tube. The measurement rod includes a set of indicators associated with length values. A surgeon may translate the provided depth gauge device over a guidewire, which causes the guidewire to force the measurement rod partially out of the tube. Once the depth gauge device contacts bone, the indicator on the measurement rod that lines up with a designated spot on the tube indicates a guidewire depth into bone, which is equal to a screw length that is needed for the procedure. Additionally, the provided depth gauge device is constructed such that the measurement rod maintains its positioning in the absence of applied force. This enables a surgeon to remove the depth gauge device from the bone or completely from the guidewire when obtaining a measurement reading.

A new and innovative method of routing a strand of material for creating a self-locking construct that joins two objects is provided. More specifically, the provided routing method includes a crossover point at which the routed strand of material crosses over itself thereby enabling the strand portions routed through one of the objects to travel in a same direction when the self-locking construct is cinched. The strand portions traveling in the same direction generates less friction between the potions than if the portions traveled in opposite directions. Accordingly, the provided routing method helps enable a self-locking construct that generates less friction than typical self-locking constructs, which thereby helps reduce the occurrences of weaknesses in the final self-locking construct. The reduced friction generation also helps increase an ease of use for a user when cinching the self-locking construct.

A bone screw is provided that reduces insertion torque when driving the screw into bone while maintaining pull-out strength. The provided bone screw includes one or more threads having a portion with a reduced flank profile that helps reduce the amount of torque required to drive the bone screw into bone. The portion with the reduced flank profile has an equal thread depth or height as the portion of the one or more threads with a non-reduced flank profile, thereby helping to maintain pull-out strength. The reduced flank profile portion is away from the bone screw's insertion tip. As such, the bone screw's non-reduced flank profile portion creates internal female threads that have a correspondingly larger flank profile than the screw's reduced flank profile portion, thereby reducing friction between the reduced flank profile portion of the one or more threads and the interior female thread.
A button inserter and system are disclosed that enable easily and effectively deploying a near bone suture button from the button inserter when implementing the suture button technique. To deploy the near bone button, with a far bone button deployed from the button inserter and against the far bone, the button inserter's handle may be translated away from the deployed far bone button. Translating the handle changes a position of a carriage body within a channel of the handle thereby compressing a spring. Protrusions on the carriage body may be forced through notches in the handle, which thereby alters an orientation of the carriage and releases the compressed spring, which applies force to the carriage body. The combination of force induces the carriage to rotate, which thereby releases the near bone button from the carriage. A free end of suture also releases from the carriage.

A new and innovative method of routing a strand of material for creating a self-locking construct that joins two objects is provided. More specifically, the provided routing method includes a crossover point at which the routed strand of material crosses over itself thereby enabling the strand portions routed through one of the objects to travel in a same direction when the self-locking construct is cinched. The strand portions traveling in the same direction generates less friction between the portions than if the portions traveled in opposite directions. Accordingly, the provided routing method helps enable a self-locking construct that generates less friction than typical self-locking constructs, which thereby helps reduce the occurrences of weaknesses in the final self-locking construct. The reduced friction generation also helps increase an ease of use for a user when cinching the self-locking construct.

AUTOMATIC RELEASE OF A NEAR BONE SUTURE BUTTON FROM A BUTTON INSERTER
A button inserter and system are disclosed that enable easily and effectively deploying a near bone suture button from the button inserter when implementing the suture button technique. To deploy the near bone button, with a far bone button deployed from the button inserter and against the far bone, the button inserter's handle may be translated away from the deployed far bone button. Translating the handle changes a position of a carriage body within a channel of the handle thereby compressing a spring. Protrusions on the carriage body may be forced through notches in the handle, which thereby alters an orientation of the carriage and releases the compressed spring, which applies force to the carriage body. The combination of force induces the carriage to rotate, which thereby releases the near bone button from the carriage. A free end of suture also releases from the carriage.
