1) degenerative disc disease (defined as discogenic back pain with degeneration of the disc confirmed by history and radiographic studies)

2) spondylolisthesis,

3) trauma (i.e., fracture or dislocation),

4) spinal stenosis,

5) deformities or curvatures (i.e., scoliosis, kyphosis, and/or lordosis),
