1. A multi-link spinal treatment system comprising:
bone fasteners having a bone screw portion, a shoulder and a locknut receiving portion, the locknut receiving portion having a diameter and a bone fastener axis;
longitudinal linking members, each of the longitudinal linking members comprising a main body having a longitudinal axis and two apertured ends having apertures sized to receive the locknut receiving portion therethrough, wherein the two apertured ends include a slotted apertured end comprising a slot having a width greater than the diameter of the locknut receiving portion and a non-slotted apertured end, wherein each longitudinal linking member main body is stepped defining an upper stepped portion comprising the non-slotted apertured end and a lower stepped portion comprising the slotted apertured end, wherein the upper stepped portion is stepped to a height of the slotted apertured end of the lower stepped portion such that a non-slotted apertured end of a first longitudinal linking member is configured for placement atop a slotted apertured end of a second longitudinal linking member;
end caps, each of the end caps comprising an aperture sized to receive the locknut receiving portion therethrough, at least one of the end caps being a slotted end cap comprising a slot having a width greater than the diameter of the locknut receiving portion; and
locknuts mounted onto the locknut receiving portions of the bone fasteners, the lock nuts securing the longitudinal linking members and the end caps against the shoulders of the bone fasteners, wherein a locknut presses the non-slotted apertured end of the first longitudinal linking member against the slotted apertured end of the second longitudinal linking member;
whereby after loosening but not removing one of the lock nuts from the bone fasteners, one of the slotted end caps is removable from the locknut receiving portion by movement in the direction perpendicular to the bone fastener axis, and further whereby the slotted apertured end of one of the longitudinal linking members is mountable onto the locknut receiving portion in place of the removed slotted end cap by movement in the direction perpendicular to the bone fastener axis.
