A system for linking bone anchors and reducing spinal deformities includes a first pair of bone screws, a first cross-link, a second pair of bone screws, a second cross-link, and a longitudinal member. The first pair of bone screws attach to opposite sides of a first vertebral level. The first cross-link includes end members that removably attach to heads of the first pair of bone screws and a first coupling feature disposed between the end members. The second pair of bone screws attach to opposite sides of a second vertebral level. The second cross-link includes end members that removably attach to heads of the first pair of bone screws and a second coupling feature disposed between the end members. The longitudinal member links the first coupling feature to the second coupling feature to enable simultaneous positioning of the first vertebral level with the second vertebral level.
