[A brief account of Mirko Brkic’s story appears on www.medjugorje.com. He is mentioned on other sites but usually in another language. I have only slightly edited it]:
Mirko Brkic broke his leg and a pin was placed in it. He was treated first in a hospital in Banja Luka and then in Belgrade. An open sore, under the knee of the broken leg, was treated many times, but the sore became deeper until the bone was visible. Doctors decided to amputate. Meanwhile Mirko’s family had made a vow to Our Lady, and prayed and fasted. The day before the scheduled amputation, the wound suddenly closed. The astonished doctors cancelled the operation. After several days the wound was completely healed over. the healing was made public on March 26, 1982.
