When a person starts to age their skeletal structure begins to weaken, and a common risk of old age is falling and breaking the hip. Hips at old age do not heal by themselves, besides the fact that in general it is extremely difficult for the body to repair. To fix this in certain cases is they open the leg, and saw out a chunk of secondary bone.

After drilling through the extremely dense dead bone in the hip, crushed boned is inserted into the area. The crushed bone taken from the sawed off bone earlier in the procedure. Supporting high density steel compound tubes are also drilled into the bone within 1mm of the surface to add structural support.
