Interspinous/inter-laminar spinal spacers (spinal spacers) are configured to be placed between bony structures (i.e. transverse and spinous processes) of adjacent vertebrae of a spine. In one form, flexible spinal spacers are defined by a unitary body that is configured to be placed between bony structures of adjacent vertebrae of a spine. The unitary body has a flex portion that provides for motion between the adjacent vertebrae to which it is coupled. The flex portion is configurable to provide for various degrees of angulation, flexion, extension and/or compression of the present flexible spinal spacer. In another form, static spinal spacers are defined by a unitary body that is configured to be placed between bony structures of adjacent vertebrae of a spine. The unitary body has saddle-shaped ends each defining a pocket that is configured to receive a bony structure of a vertebra. The pockets may or may not be textured and/or may or may not include teeth, serrations or ridged surfaces to secure the spinal spacer to the bony structure.
