Osteoporosis is defined as a systemic skeletal disease that is characterised by low bone mass and microarchitectural deterioration of bone tissue. with a consequent increase in bone fragility and susceptibility to fractures. Therefore. the diagnosis of osteoporosis is based on measurement of bone mineral density (BMD) using central (axial) dual energy X-ray absorptiometry (DXA). https://www.ealisboa.com/great-deal-Pentair-Union-Collar-2-U11-200PS-super-offer/
