Abstract
The present disclosure describes surgical anchors and related devices and methods that can be used for surgical bone fracture fixation. Some implementations use a polymeric cored braided suture held in place by anchors on each side of a fracture. In some implementations, the anchors are secured into bone while maintaining high tension (e.g., relative to certain prior art methods) in the suture during the deployment process. Some implementations provide for tensioning (e.g., using a polymeric cored braided suture) to compress the fracture and hold the bone in place, functioning as though the suture has sewn the bone (e.g., fragments or portions) together. This can, for example, provide rigid fixation of a fracture which may be important for healing to occur. The tension preload can provide compression to maintain fixation in the face of tensile and shear loads applied to the bone (e.g., as a result of movement and weight bearing).
