In the first week of this month, my mother-in-law had an unfortunate accident at the market. She's 77 years old, though she's no ordinary old lady. At her age, she's still spritely in her activities and manages to do most household tasks without any problem. She doesn't seem to tire easily compared to most senior citizens.
I would say she's the healthiest and strongest 77 year-old woman that I've seen.
The above thumbnail with an x-ray image doesn't belong to her, by the way. But that solid white shape on the right shows an implant that is very much similar to what she now has in her right hip and thigh bone.
The implant is an 8-inch titanium piece with a ball (femoral head) on top roughly 4 centimeters in diameter.
