Magnetic resonance imaging (MRI) showed L4-5 disc herniation with a bilateral foraminal stenosis and an L2 wedge vertebrae with kyphosis (Fig. 1).
Postoperative plan radiography shows interbody cage insertion at L4-5 level with fusion extension to L4. A: anterior-posterior view, B: lateral view.

He underwent anterior lumbar interbody fusion (ALIF) at the L4-5 level with bilateral foraminal decompression and posterior screw fixation ( Fig. 2).
After 8 months of operation, follow-up plan radiography showed retrolisthesis at L3-4 level and left L4 screw position change. CT scan shows periscrew hallo (white arrow). A: anterior-posterior view, B: lateral view, C: CT scan coronal view.

Radiography and a computed tomography (CT) scan showed retrolisthesis at the L3-4 level and a position change of the left L4 screw with peri-screw halo (Fig. 3).
Plan radiography shows L2 corpectomy and mesh cage insertion, L3-4 interbody cage insertion, fusion extension to T12 level, and kyphosis correction state. A: anterior-posterior view, B: lateral view.

One month postsurgery he experienced left abdominal flank discomfort and bulging below the skin incision on the lateral approach side (Fig. 5).
CT scan shows left abdominal flank bulging accompanied by abdominal muscle thinning, and no evident of abdominal facial defect and bowel hernia (white arrow).
