Intraoperative Myelography in Transpsoas Lateral Lumbar Interbody Fusion for Degenerative Lumbar Spinal Stenosis: A Preliminary Prospective Study

Figure 3

Radiographs of Case (C): preoperative myelography identified filling defects of both L3-4 and L4-5 levels ((a) and (b)). Intraoperative myelography did not reveal adequate indirect canal decompression at L3-4 level ((c) and (d)). Sufficient canal decompression was achieved after same-level MECD ((e) and (f)).
