The morphometric parameters of femur proximal part and its relationship with body mass index

The femur is the longest bone in the body. Injury or fracture in this bone strongly affects the quality of life of people. The aim of this study was to investigate the morphometric parameters of femur proximal part and its relationship with body mass index (BMI). This descriptive-analytical study was conducted on 200 patients over 50 years of age referred to Shahid Beheshti Hospital in Kashan and Ayatollah Kashani Hospital in Isfahan during 2018-2019. The participants had radiographs in the supine position of femur proximal part. BMI and bone mineral density of patients were determined by the DXA method. Using radiographic images of the femur, the morphological features were evaluated. Also, the relationship of these characteristics with age, gender, BMI and bone mineral density was investigated. The values of six morphological parameters of the femur in the patients under study were Q-angle=121.93±3.78, TW=86.06±7.65, HW=52.4±4.69, FW=37.74±4.29, HAL=118.43±10.47 and FAL=105.34±7.59 mm, which were higher in men. There was a direct and significant correlation of 23% between age and TW, which was significant according to the Pearson Correlation Test (P=0.039). Inverse correlation of 14% was observed between HAL width and BMI, which was statistically significant (P=0.042). FAL variable had a decreasing trend with decreasing BMD (P=0.031). Proximal femur characteristics were significantly related to factors such as gender and BMI. The morphological specifications of femur proximal were higher in men than in women. Compared to evaluations in other regions, the included characteristics are distinct from other countries, which these differences can be caused by genetic characteristics, environment, nutritional status, and lifestyle.
