The female elephant Mosha was 7-month-old when we must amputated her leg cause she walked(worked) on an land mine in Thailand. Decade later, she weighs more than 1800 Kg and benefited from nine different prostheses to support her weight throughout her growth. However, the way she walked was unbalanced and its vertebral column was going to bend. In time, it would have damaged the cartilages and the elephant would have finally stopped walking. She would have died from it. Thanks to surgeons of an elephants hospital which is situated to Lampang, in Thailand, and to the work they supplied for the realization of this huge prosthesis, Mosha can again walk correctly and live peacefully for numerous years.
