Sarcopenia and fragility fractures: molecular and clinical evidence of the bone-muscle interaction.

➤ Bone and muscle tissues are in close relationship, and the aging process is a factor involved in the loss of the functionality of both bones and muscles.➤ Sarcopenia and osteoporosis are linked from a biological and functional perspective and are related to an increased fracture risk in the elderly.➤ The increased fracture risk in sarcopenic and osteoporotic subjects is due to the decline of muscle mass and strength, the decrease in bone mineral density, and limited mobility.
