Degenerative scoliosis in resulted from lumbar degenerative changes, including narrowing of several discs and vertebral wedging or collapse with predominant scoliosis. The curve involves segments from the lower thorax to L5 with an apex at L2 or L3. It may result from degeneration of de novo or preexisting idiopathic, as well as iatrogenic or traumatic causes.
In degenerative scoliosis, increased extremity radicular pain and claudication are due to neural compression; this is relieved with thorough neurologic decompression. Degenerative pain is caused by disc and facet instability and degeneration due to deformity and imbalance; this is relieved with deformity correction, fixation, and fusion. Myogenic pain is caused by lumbar muscular fatigue and is relieved by restoring sagittal and coronal balance.
Degenerative scoliosis results from multiple discs degeneration, vertebral body wedging. The x-ray films shows osteophytes formation and laterolisthesis.
