23 years ago my son David almost lot his leg but because of Dr. Sha's help saved my son's shattered thigh by putting a rod in it from the hip to the knee. A lot of the bone was missing. Over the next year the missing bone grew back we were able to have the rod removed 2 years later. This procedure should be tried before removing anyone's body parts. Thanks to Dr. She my son is hers today to help me with my ALS.
