Symptomatic lumbar scoliosis with degenerative changes in the elderly.

Lumbar scoliosis with degenerative changes in the elderly presents with spondylosis, variable apophyseal joint arthrosis, laminar hypertrophy, and marginal osteophytos most prominent within the scoliotic apex. Resultant lumbar stenosis, alone or with ventral spurs and herniated discs as isolated or associated lesions, can produce disabling low-back and lower extremity pain, weakness, and neurogenic claudication relievable by appropriate decompressive surgery. Myelography is essential as a preoperative measure. Whether such scoliosis is superimposed on adolescent thoracolumbar scoliosis or arises anew in later life remains an open question.
