Prediction of osteoporosis through radiographic assessment of proximal femoral morphology and texture in elderly; is it valid and reliable?Özkan Köse1, Ömer Faruk Kılıçaslan1, Hasan Onur Arık2, Ümit Sarp3, İclal Erdem4, Mehmet Uçar51Antalya Education And Research Hospital, Department Of Orthopedics And Traumatology, Antalya, Turkey2Yozgat State Hospital, Department Of Orthopedics And Traumatology, Yozgat, Turkey 3Yozgat State Hospital, Department Of Physical Medicine And Rehabilitation, Yozgat, Turkey 4Antalya Education And Research Hospital, Department Of Radiology, Antalya, Turkey 5Bozok University, Medical Faculty, Department Of Physical Medicine And Rehabilitation, Yozgat, Turkey Objective: The purpose of this study is to determine the best predictive radiographic measurement method to identify the presence of osteoporosis and test the inter-observer and intra-observer reliability and validity of these methods in postmenopausal women. Materials and methods: Ninety-two elderly female patients who presented with hip pain were prospectively evaluated. Hip radiographs were used to determine the values of Singh index (SI), Canal-to-Calcar Ratio (CCR), and Cortical Thickness Index (CTI). All measurements were performed by two independent observers on two separate occasions, at least 4 weeks apart. Bone mineral density (BMD) was assessed by DEXA. In the first part of analysis, reliability of the all measurement methods was tested. In the second part, correlation coefficient (Pearson r) was used to determine the relationship between the measurement methods and BMD. Finally ROC curve analysis was performed to determine the threshold values, sensitivity and specificity for each radiographic measurement method. Results: Intra-observer reliability analysis of Sing index revealed kappa coefficient of 0.359 for Observer A, and 0.224 for Observer B. Inter-observer reliability analysis of SI revealed kappa coefficient of 0.070 for observer A and 0.051 for observer B. The intra-observer and inter-observer reliability was good and excellent for CTI and CCR for both observers. There was no correlation between Singh index and BMD. On the other hand, there was significant correlation between CTI and CCR and BMD. All measured indices were significantly different (p<0.05) between osteoporotic and non-osteoporotic patients. CTI value less than 0.3 or CCR value less than 0.47 reflects the presence of osteoporosis with 100% sensitivity and 98% specificity. Conclusions: SI is not reliable and do not correlate with BMD. However, both CTI and CCR showed good and excellent reliability, and each index correlated well with the real BMD values.
