Background: Femoral neck fracture is one of the most common fractures in elderly. Proximal femur fracture in elderly patients is considered a severe morbidity which has a negative impact on the life expectancy and quality of life. Aim of this study was to find the correlation of cortical thickness index (CTI) and SI toward bone density (BMD) in female patients over 60 years of age with femoral neck fracture.

Methods: This is an observational cross-sectional study. Subjects were selected from Sanglah general hospital outpatient department, Denpasar, Bali during the period October 2020 to January 2021 by inclusion requirements and then randomized into two groups. Data were taken through history taking, physical examination as well as supporting investigations such as contralateral hip joint radiograph and BMD measurements. Statistical analysis was done from those data.

Results: It has been obtained that there was a positive correlation of Singh index (SI) and CTI toward BMD. The correlation coefficient (r) between SI and BMD was 0.874 (p=0.000). The r between CTI and BMD was 0.854 (p=0.000). Both variables were significant.

Conclusions: There were significantly strong correlations between SI and BMD (r=0.874, p=0.00), also CTI and BMD (r=0.854, p=0.00) in female patients over 60 years of age with femoral neck fracture.
