Osteoporosis is a type of systemic bone disease wherein the patient is highly vulnerable to bone fracture because of the decrease in bone density and quality, destruction of the bone microstructure, and an increase in the bone fragility. Most of the osteoporotic subtrochanteric fractures are unstable in nature, requiring the conservative treatment of a long-duration bed rest and traction; this condition is prone to complications resultant from extended bed rest, often leading to death.
