Osteosarcopenia increases hip fracture risk: A case-controlled study in the elderly.

Abstract

The aim of this study was to determine the relationship between bone mineral density (BMD), gluteus maximus muscle volume, and hip fracture type in patients with hip trauma. A total of 134 patients were included in the study; 76 were in the study group [mean age 71.89 (65-80)] (hip fracture group), and 58 were in the control group [mean age 71.27 (65-80)] (hip trauma without fracture). The fracture type, femoral head diameter (FHD), and body mass index (BMI) were assessed. Fracture type was evaluated according to AO/OTA classification. The total gluteus maximus volume t (GMV) was evaluated via computed tomography (CT). In both groups, there were significant positive correlations between BMD and tGMV/FHD, tGMV/BMI, and tGMV. When comparing the groups regarding total muscle volume, the muscle volume in the control group was significantly higher. According to this study, GMV have an impact on bone mineral density. The risk of hip fracture should not be assessed by only examining bone density in patients over 65 years of age. The clinical relevance is that increasing the gluteal muscle volume above cut-off value in elderly individuals may help to reduce hip fracture risk.
