Diagnostic Value of Mid-Thigh and Mid-Calf Bone, Muscle, and Fat Mass in Osteosarcopenia: A Pilot Study

Abstract

Osteosarcopenia is defined as the concomitant occurrence of osteoporosis and sarcopenia. Current lack of consensus on sarcopenia definitions, combined with the low sensitivity and specificity of screening methodologies, has resulted in varying prevalences of sarcopenia, and consequently osteosarcopenia diagnosis. Previous research indicates that mid-thigh is a potential surrogate region for the assessment of bone, muscle, and fat mass in a single, efficient and low-radiation dual x-ray absorptiometry (DXA) scan. We hypothesized that muscle and bone mass measurements in the mid-thigh region can be used to evaluate bone and muscle health and function. A retrospective study was conducted on com..
