[Osteoporosis liaison service].

Osteoporosis is nowadays big burden for aging societies. However, low treatment rate even after first hip fracture results in the increase of second hip fracture in both developed and developing countries. Fracture liaison services, commonly known as FLS, are coordinator-based, secondary fracture prevention services implemented by health care systems for the treatment of osteoporotic patients. Osteoporosis liaison service (OLS) in Japan includes not only FLS but also educational program, medical check-up for bone fragility and risk assessment for primary fracture in osteoporotic subjects. Japan Osteoporosis Society gives coordinators and medical doctors the certificates as a specialist for OLS since 2015. OLS in Japan should facilitate better performance of the treatment of osteoporosis and should contribute the reduction of clinical fractures.
