The human skeletal system is a complex organ in constant equilibrium with the rest of the body. In addition to support and structure of the body,<unk>  is the major reservoir for many minerals and compounds essential for maintaining a<unk> y pH balance. The deterioration of the body with age renders the elderly particularly susceptible to and affected by poor<unk> . Illnesses like osteoporosis, characterized by weakening of the<unk> 's structural matrix, increases the risk of hip-fractures and other life-changing secondary symptoms. In 2010, over 258,000 people aged 65 and older were admitted to the hospital for hip fractures. Incidence of hip fractures is expected to rise by 12% in America, with a projected 289,000 admissions in the year 2030. Other sources estimate up to 1.5 million Americans will have an osteoporotic-related fracture each year. The cost of treating these people is also enormous, in 1991 Medicare spent an estimated $2.9 billion for treatment and out-patient care of hip fractures, this number can only be expected to rise.
