Underneath nerve tissue of the spinal cord was split by a perpendicular bony spur and connected from its tip to the upper lamina [Figure 1a and b]. Spinal X-rays showed a bony spur on the L2 vertebral column and laminar defect in the lumbo-sacral area [Figure 1c].

The spur was seen extending from the posterior border of the vertebral body and penetrating the anterior dura [Figure 2a]. Fibrous attachment between the bony spur and the upper lamina was resected [Figure 2b].

The bony spur is then resected from its base to expose the opened anterior dura of the spine [Figure 3a]. The anterior dura was sutured [Figure 3b], and the spinal roots were demonstrated [Figure 3c].
