The progression of adolescent idiopathic scoliosis is typically monitored via
regular radiographic follow-up. The Cobb angle (as measured on whole-spine
radiographs) is considered as the gold standard in scoliosis monitoring.
OBJECTIVE: To determine the sensitivity and specificity of back surface
topography parameters, with a view to detecting changes in the Cobb angle. METHOD: One hundred patients (mean age: 13.3) with Cobb angles
greater than 10 degrees were included. Topographic parameters were measured in a
standard position and in a position with hunched shoulders. Gibbosities and
spinal curvatures were evaluated. RESULTS: An increase of more than 2 degrees in
any one gibbosity or in the sum of the gibbosities (in either of the two
examination positions) enabled the detection of a five-degree increase in the
Cobb angle with a sensitivity of 86% and a specificity of 50%. CONCLUSION: If the
present results are confirmed by other studies, analysis with back surface
topography parameters may reduce the number of X-ray examinations required to
detect increases in the Cobb angle.
