A spinal rod system (10, 110, 310, 510, 560, 610, 660, 710) includes a first rod (12, 112, 212, 312, 512, 562, 612, 662, 712) and a second rod (30, 130, 230, 330, 530, 580, 630, 680, 730) engaged to one another in end-to-end fashion. A coupling mechanism (28, 228, 328, 428, 528, 578, 628, 678, 728) allows the spinal rod system (10, 110, 310, 510, 560, 610, 660, 710) to be assembled with rod portions (14, 32, 114, 132, 214, 232, 314, 332, 514, 532, 564, 582, 614, 632, 664, 682, 714, 732) having the desired characteristics while minimizing the footprint of the coupling arrangement between the first and second rods.
