An apparatus for anchoring cable to bone includes an anchor configured to be anchored in a bone and a cable fixed to the anchor. The cable is configured to be tensioned to a measurable and adjustable tension to cause a measurable and adjustable compression of the bone by the cable. The apparatus may include a cable housing having a proximal portion, a distal portion, and a passage. The distal portion is detachably and co-rotatably engageable with the anchor and the passage is open to and extends from a distal end of the distal portion. The apparatus also includes a cable having a fixed-end portion and a free-end portion. The fixed-end portion of the cable is fixed to the anchor and the free-end portion of the cable is non-fixedly positionable in the passage of the cable housing.
