A 64-year-old woman complained low back pain with bilateral sciatica and claudication for several years. Radiographs of anteroposterior view (A) and lateral view (B) showing degenerative lumbar scoliosis from T12 to L5 with lateral bridged traction vertebral osteophytes over L2-3,L3-4 associated with severe disc space narrowing over L1-2 ,L2-3. After anterior lumbar interbody fusion with three SynCages over L1-2, L2-3, and L3-4, the scoliotic angle (T12-L4) was improved from 37° to 17° (C) and the lumbar lordotic curve was improved from 4° to 29° (D). One week later, posterior instrumentation of T12-S1 with posterior interbody fusion of L5-S1 was performed. The scoliotic angle was improved from 17° to 6° (E) and the lumbar lordotic curve was improved from 29° to 36° (F).
