[Results of a vertebral deformity screening in the students of the district of Florence (Tuscany Region, Central Italy)].

OBJECTIVES

to observe the prevalence of vertebral deformities in an adolescent population in the 178 schools of the District of Florence (Tuscany Region, Central Italy), correlating these results with clinical aspects as ligamentous laxity and verifying if these data are in agreement with what emerged in literature in studies of the same type.

DESIGN

prevalence study.

SETTING AND PARTICIPANTS

report of the results of a school screening for vertebral deformities in an adolescent population of 11,820 students of the Schools of District of Florence held between November 2010 and June 2013.

MAIN OUTCOMES MEASURES

asymmetry of waist triangle; trunk imbalance using plumb-line from C7; leg length discrepancies; presence of gibbus and measurement of Angle of Trunk Rotation using Bunnell scoliometer; measure of thoracic kyphosis (a value of kyphosis> 50° was considered to be at high risk of hyperkyphosis making it necessary to request an X-ray); ligamuentuos laxity using Beighton Score.

RESULTS

11,820 students were screened; 85.95% of them had no significant spinal deformities; 14,05% of the students showed significant clinical signs of scoliosis; 28.46% of the students had a thoracic hyperkyphosis (>40°), 1.55% of those presented a non-reducible thoracic hyperkyphosis. Results show a statistically significant correlation between the severity of the deformities and the score of the Beighton Score.

CONCLUSIONS

the results confirm the association between vertebral deformities and ligament laxity. The prevalence of vertebral deformities in the school age population of the Municipality of Florence is 14.05%, in accordance with what emerged in the literature from similar studies.
