In January 2003, Penny Woodworth, who lives on Vancouver Island, BC, was taking a jumping lesson. “Smallish jumps, nothing exciting. My long-time error is looking down, which I did that day. My horse stopped, and I tumbled off. Not a bad fall at all, except that I landed with one butt-cheek on the ground pole. I got up and carried on, but I was crooked and stayed that way. After a week or so, still riding crooked and feeling shooting pains down my right leg, I went for physiotherapy. I had dislocated my sacroiliac (SI) joint. Regular physio treatments and exercises finally got it to stay in place and I continued riding.
