A word of warning, if you aren't comfortable with the more graphic side of medical descriptions, you might want to give following the link below a miss.
As some of you might know, the Holy Shroud of Turin is one of my loves, and I like to keep up with any scientific news relating to it. This article from the Vatican Insider is more evidence, if any more were required, of the love Our Lord has for us and how much he suffered for us. It details damage to the shoulder and neck causing paralysis of the right arm following a blunt force trauma to the shoulder area. This was probably caused by a fall, led to an inability to carry/hold anything. There is also more insight into the crucifixion itself, and a lot more I shan't précis here.
