|dc.description||Scoliosis with progressive deformity can develop late in life. The authors studied 200 patients older than
age 50 years with back pain and recent onset of scoliosis. Seventy-one percent of patients were women,
and no patient had undergone spinal surgery. The curves involved the area from T12 to L5 with the apex at
L2 or L3 and did not exceed 60 degrees. Degenerative facet joint and disc disease always were present, and
the curves were associated with a loss of lumbar lordosis. Forty-five patients with severe pain and
neurologic deficits were studied using myelography. Indention of the column of contrast medium was seen
at several levels but was most severe at the apex of the curve. It was least severe at the lumbosacral joint.
The curves progressed an average of 3 degrees per year over a 5-year period in 73% of patients. Grade 3
apical rotation, a Cobb angle of 30 or more, lateral vertebral translation of 6 mm or more, and the
prominence of L5 in relation to the intercrest line were important factors in predicting curve progression||en_US
|dc.description.abstract||Scoliosis, simply defined as a lateral curvature of the spine, has been recognized clinically for centuries.
The deformity is actually much more complex and to describe more completely and quantify scoliosis
deformity, three planar and three dimensional terminology and measurements are required . However, for
practical purposes the deformity is most conventionally measured on standing coronal plane radiographs
using the Cobb technique
For a few of the patients an underlying cause can be determined, including congenital changes, secondary
changes related to neuropathic or myopathic conditions, or later in life from degenerative spondylosis.
However, the cause of most scoliosis is not known and since about 1922 such patients have been diagnosed
as having idiopathic scoliosis||en_US
