Artificial disc replacement (ADR) is usually performed through anterior midline approaches from L5-S1 up to L2-3 segment. However, in the L1-2 segment, ADR through a midline approach is often difficult due to the existence of renal vessels. We report two patients with juxtafusional degeneration syndrome at the L1-2 segment. Artificial disc replacement was performed through an anterolateral approach and was completed without any intraoperative complications. The patients were allowed to ambulate on the first postoperative day with a light corset. Artificial disc replacement through an anterolateral approach may be useful in the upper lumbar segments when kidney and renal vessels preclude a direct anterior approach.
