Does scoliosis causes low bone mass? A comparative study between siblings

Abstract

The aim of this study is to assess the prevalence low bone mass among girls with adolescent idiopathic scoliosis (AIS) and their siblings. The subjects of this study were Saudi Arabian girls with AIS. Patients had their weight and height measured to calculate their body mass index (BMI). Clinical examination and investigations were done to rule out any other cause of scoliosis. All had bone mineral density (BMD) measurement of hip area and the spine using DEXA scan, Hologic Inc. Patients with a BMD of < -2.6 was taken as osteoporotic and those between < 0.001. T- and Z-score was also lower in scoliotic girls in comparison with girls with normal spine significant at P < 0.001 (CI 95%). Our study indicates that the scoliosis causes osteopenia and osteoporosis among girls while their siblings with normal spine remain with normal bone mass. © 2008 Springer-Verlag.
