Usefulness of cortical thickness ratio of the third metacarpal bone for prediction of major osteoporotic fractures.

Objective: Patients with rheumatoid arthritis (RA) are at high risk for osteoporotic fractures. We developed an index called the third metacarpal cortical thickness ratio (CTR), which reflects bone mineral density (BMD) in RA patients. A longitudinal study was conducted to verify the usefulness of CTR during the follow-up period.

Musculoskeletal ambulation disability symptom complex as a risk factor of incident bone fragility fracture.

Objectives: Influence of presenting musculoskeletal ambulation disability symptom complex (MADS) on occurrence of bone fragility fracture (BFF) is investigated with retrospective cohort study.

Methods: A total of 931 subjects joined in the study. Subjects were selected as bone fragility risk positive in the fracture assessment tool questionnaire.
