Overview of osteo-articular involvement in systemic sclerosis: Specific risk factors, clinico-sonographic evaluation, and comparison with healthy women from the French OFELY cohort.

Osteoarticular involvement in systemic sclerosis (SSc) is frequent and varied. Data are scarce on the prevalence and risk factors of osteoporosis (OP). We aimed to assess clinical parameters, radiological parameters, US articular involvements, and the frequency of OP and evaluate SSc-specific risk factors.
