Apparatus and method for dynamic connection between adjacent bones. Various embodiments pertain to a bone anchor that includes a rotatable spool, the spool being configured to place tension on a flexible member, such as a tether, suture, cable, or other. Still further embodiments pertain to tools for interconnecting two bone anchors with a tether.

Apparatus and methods for spooled vertebral anchors

Methods and devices for the tailored restraint of two separate bones, in which the bones are generally permitted to rotate relative to one another, or move toward each other, but are restrained from separating beyond a predetermined, fixed distance. In some embodiments, the restraint is provided by compressing a tether into a notched groove.

Tethered restraint of vertebral bodies

Implantable devices for dynamic interconnection between bones, and especially between vertebrae. The devices provide for various types of manipulation of a flexible connection such as a tether, such as by providing an aperture through which the flexible connection is passed and guided, or a post to which a loop of the flexible connection can be attached, or a groove in which a loop of the flexible connection can be placed.

Segmental tensioning of spinal tethers

Methods and apparatus for coupling two or more bones together with a flexible connector.

Bone anchors with cord retention features

An apparatus includes a first flexible connector and a second flexible connector. The apparatus also includes a first bone anchor including a first tethering head configured to receive a first portion of the first flexible connector. The apparatus also includes a second bone anchor including a second tethering head configured to receive a second portion of the first flexible connector. The apparatus also includes a third bone anchor defining a first aperture configured to receive therethrough the first bone anchor. The third bone anchor also defines a first peripheral channel configured to receive a first portion of the second flexible connector. The apparatus also includes a fourth bone anchor defining a second aperture configured to receive therethrough the second bone anchor. The fourth bone anchor also defines a second peripheral channel configured to receive a second portion of the second flexible connector.

Dual tether support of vertebra

A system for interconnecting bones includes an implantable member configured to be mechanically coupled to a first bone, configured to be mechanically coupled to a second bone, configured to provide substantially no resistance to compression of the implantable member, configured to support a tensile load within a predetermined range of tensile loads extending from a first load to a second load, configured to have a predetermined elasticity within the range of tensile loads, configured to have a first characteristic at the first load, and configured to have a second characteristic at the second load. The system also includes a means for measuring the first characteristic and the second characteristic. And the system includes a means for calculating a tension between the first bone and the second bone based on the first characteristic and the second characteristic.
