Platelet Calmodulin Levels in Adolescent Idiopathic Scoliosis

It appears that platelet calmodulin levels correlate closely with curve progression and stabilization by bracing or spine fusion. Correlation with nonprogressive curves was not as consistent, with 27% noncorrelation. Longer follow-up evaluation and enrollment of additional patients will be necessary to determine whether calmodulin may serve as a biochemical marker of curve progression and to help identify stable and progressive curves.
