Apparatus and method for treating spinal conditions by moving or spatially fixing at least one vertebra relative to another vertebra. The device includes link members (10, 20, 30) the ends (12, 14, 22, 24, 32, 34) of which are secured to adjacent vertebra and which are offset from central portions (16, 26, 36) of the link members (10, 20, 30). The link members are in the form of a C-shaped or V-shaped rod or plate to form the offset. The offset provides increased bone volume that can be used for grafts or fusion. Attachment structure in the form of bone screws (50), bolts or hook members (80) are provided to secure the link members (10, 20, 30) to respective vertebrae or other bones. A plurality of link members can be used to connect multiple points on a plurality of vertebrae or other bones even though those points are nonlinear (Fig. 5). In another aspect of the invention, a multidirectional attachment member (750) may be used with the link members to form a spinal implant or bone fixation system.
