How do scoliotic women shrink throughout life ?
In this cross-sectional study, shrinkage of ageing scoliotic women was defined as the difference between the self-reported peak body height and the current measured height. 2 groups of scoliotic women over age 40 were examined.
In the first group (n=60, age=63.7 ± 10.4 years, various patterns of scoliosis), current body height and peak body height were strongly correlated (r=0.87 ; P<0.001).
The average shrinkage was 1.5 cm per decade, had begun early in adulthood, was due to the combined effects of age and scoliosis, and was especially associated with rotatory olisthesis (8 ± 3. cm vs. 3.9 ± 3.1 cm).
The second group was drawn from the first one (n=17) in order to develop a model for estimating the natural history of scoliosis from shrinkage.
We considered only lumbar or thoraco-lumbar scolioses between 20° and 80° with an X-ray follow-up (19.7±7.3 years).
Under these conditions, the curve progression was highly related to shrinkage (r=0.74 ; p<0.001, y=0.7+2.7x ; standard error=0.42), which allowed us to generate prediction limits of curve progression for the individual.
Since the determination of shrinkage would provide a simple, non-invasive, and inexpensive method of monitoring the natural history of scolioses in adults, it could be incorporated in routine clinical procedures.
Such an indicator may also be useful for classifying the scolioses diagnosed in the second part of life as degenerative or not.
