Abstract
AbstractBackground: Osteoporosis is a common condition, especially affecting the older female population. The ability to predict loss of lumbar height using simple anatomical measurements would be a useful tool.Aim: To examine the relationship between CID/AS ratio and spinal height. And if there was a correlation between CID/AS ratio and early osteoporosis..Methods: A case-control study was designed, 50 post-menopausal women as cases and 50 as controls aged 50-70 were recruited who attending DEXA unit, Eldemerdash hospital, Ain Shams University during the period between June 2016 to Marsh 2017. Arm span (AS) and the costo-iliac distance (CID) was measured as the number of cm between the costal margin and the pelvic ridge of a patient, measured in the midaxillary line, the CID/AS ratio was calculated. The L1–L4 vertebral height of each patient was obtained from dual-energy X-ray absorptiometry (DEXA).Results: The age of the studied cases, mean age 59.65 and SD 5.25. While the age of studied controls, mean age 57.67 and SD 5.48 (P value 0.07), the study was showed that no significant association between CID/AS ratio and lumber vertebral height, but there was a statistically correlation between CID/AS ratio and DEXA results (T score) with best cut off value CID/AS ratio > 0.058, Sensitivity = 74% Specificity = 60%Conclusions: The CID/AS ratio is a useful bedside test in identifying patients with osteoporosis.

While the age of studied controls, mean age 57.67 and standard deviation (SD) 5.48 (P value 0.07), the study was showed that no significant association between costo-iliac distance (CID)/Arm span (AS) ratio and lumber vertebral height, but there was a statistically correlation between CID/AS ratio and DEXA r esults (T score) with best cut off value CID/AS ratio > 0.058, Sensitivity = 74% Specificity = 60%
Osteoporosis is a common condition in the older female population, with an incidence of 15% in women over 50 years of age
Summary
Osteoporosis is a common condition, especially affecting the older female population. Osteoporosis is a common condition in the older female population, with an incidence of 15% in women over 50 years of age. Prevalence in the 80- to 89 -year-old age group is approximately 48% in the United States 1. As 26% of men have osteopenia and 21.9% have osteoporosis 2, osteoporosis is projected to impact approximately 14 million adults over the age of 50 by the year 2020. Osteoporotic fractures are associated with increased mortality and major morbidity, including loss of independence, reduced function and mortality, pain, kyphosis and respiratory compromise 3. The mortality rate associated with hip fractures is higher, vertebral fracture is associated with substantial morbidity, including chronic back pain, reduced truncal postural flexion, restricted movement and increased risk of falls 4
