Osteoporosis is a systemic disorder of the skeleton that is characterised by a reduction in bone mass and deterioration of bone micro-architecture. Although the condition affects a higher percentage of women, it is now known that substantial bone loss occurs with advancing age in men. The importance of osteoporosis lies in the fact that osteoporotic bones are more fragile and susceptible to fracture than normal bones. Osteoporotic fractures usually occur in skeletal sites that are rich in trabecular bone. The most common low-energy fractures are those of the vertebrae, wrist and hip. Studies show that the number of osteoporotic fractures is increasing worldwide mainly due to the extension of the average lifespan. The total number of hip fractures in the European Union is estimated to increase from 414,000 in 2000 to 972,000 in 2050 [1].
