Extra joint stabilization construct
First Claim
1. A knotless returning and locking system for bone fracture stabilization and soft tissue repair and reinforcement, comprising:
- a returning and locking anchor having a body with a proximal end, a distal end, and defining a longitudinal axis, the body forming an internal passage and a return feature, the internal passage having a threaded receiver located at the proximal end of the body and including a proximal portion, a mid portion, and a distal portion, the return feature located distal to the threaded receiver and in communication with the internal passage; and
a threaded set screw having a proximal portion, a mid portion, and a distal portion, the threaded set screw configured for rotational insertion into the threaded receiver to achieve a progressively increasing interference fit about a flexible synthetic strand passing between the proximal portions and the mid portions of the threaded receiver and the threaded set screw and a progressively decreasing interference fit about the flexible synthetic strand passing between the mid portions and the distal portions of the threaded receiver and the threaded set screw, wherein the progressively increasing interference fit and the progressively decreasing interference fit combine to provide a locking feature that reversibly secures the flexible synthetic strand in relation to the returning and locking anchor.

Abstract
The disclosure provides devices and methods of use pertaining to extra joint stabilization. Embodiments include a number of suture returning and locking anchors that feature both a suture return element and a suture locking feature that employs an interference fit between a flexible synthetic strand, a receiver of the anchor, and a set screw, where the receiver and the set screw each have a number of gradual, opposing tapers to facilitate gradual proximal-to-distal gripping and releasing of the flexible strand to achieve an optimal locking force while preventing severing of the flexible strand. Embodiments also include a counter-torque anchor driver configured to resist torsional forces generated during and translated to the anchor during set-screw insertion. Further embodiments include extra joint reinforcement, stabilization, and attachment constructs formed using the disclosed devices. Other embodiments are disclosed.
