Sarcopenia and Its Association With Change of Bone Mineral Density and Functional Outcome in Old-Aged Hip Arthroplasty Patients

Abstract

This study aimed to investigate the relationship between sarcopenia and change in bone mineral density (BMD) and functional outcome in hip arthroplasty patients. Methods: Among the 221 patients who had undergone hip arthroplasty, 147 patients were enrolled. All patients were divided into 2 groups according to presence of sarcopenia. Bone mineral density (BMD) at hospitalization and 1-year after surgery and Barthel index was measured at the time of before injury, hospitalization, 3 months and 1-year after surgery. Results: BMD at hospitalization showed.627 ±.082 (g/cm2) in Sarcopenia and.726 ±.059 (g/cm2) in Non-sarcopenia at femur (total) site (P
