Billy was born with spina bifida, one of the most common birth defects. It involves incomplete closure of the lining of the spinal cord, resulting in an incomplete spinal cord. Vertebrae overlying the exposed area and unfused and open, which results in the abnormal part of the spinal cord protruding through the vertebrae. The lining can be closed surgically after birth, but the individual will continue to have dysfunction of the spinal cord, mainly affecting the muscles of the hips, knees and feet. Spina bifida, Latin for "split spine", affects 1.5 of every 1,000 births.
According to Teammate Jean Labonté
“What do Billy Bridges and Zdeno Chara have in common? They both have the hardest shot in the business. When Bridges shoots, you do not want to get caught between the puck and the net. But Bridges offers much more than a powerful shot. He is an extremely skilled player – he's fast, big and likes physical play. Around the net, he's the sniper par excellence.”
