Canal to calcar ratio is associated with lumbar compression fractures

Objective: Osteoporosis is one of the major public health problems. Singh (SI) and Genant indexes are the most well-known osteoporosis evaluation methods. Femoral cortical thickness index (CTI) and femoral canal to calcar ratio (CCR) values have been found to be more informative in the literature. This study aimed to investigate the relationship between SI, CTI, CCR, bone mineral density, and blood tests. Patients and Methods: Hospital digital archives were searched and postmenauposal female patients who underwent bone scanning between 2018 and 2020 were included. Demographic data, blood laboratory and bone mineral densitometry (BMD) test results, and radiographic views were collected. The results were statistically analysed and expressed as mean +/- standard deviation. Results: The mean age was 66.14 +/- 6.82 years. There were 22 patients with lumbar compression according to Genant criteria. Also, 52 patients had osteoporosis and 35 patients had osteopenia according to the spine or hip BMD T scores. CCR was found to be significantly related to lumbar compression (p=0.04). Conclusion: In this study, no correlation was found between CCR value and T score. However, CCR value was found to be associated with lumbar vertebral compression, which is helpful in the diagnosis of osteoporosis. It may be considered as a parameter that should be studied more in the diagnosis of osteoporosis.
