Yep, the compartment syndrome is a thing that many/most of us don't know about. What's a bit of swelling after all? Goes down after a couple of days doesn't it, surely? What was interesting, maybe, about this incident was how it evolved. It happened on a Sunday afternoon about 14:00. We'd been on a weekend ride of mostly single track and fire trails, NOT DR650 riding, and this was Day 2 and almost back to the car park, maybe and 1.5 hrs to go. We'd had to come out onto the road to get across the river on a bridge so it was the first bit of sealed road for about 100 kms. I was sweep riding and it took a while to get radio contact established and eventually get to a vehicle and recover me and the bike. It was rideable, but I wasn't. Back at the car park, my bike was loaded into my ute and a mate drove me and my ute and bike to casualty at Canberra Hospital, arriving about 17:00, right on peak hour. After about an hour of hanging, and my mate needing to be elsewhere, and not knowing what might be happening to me and my ute and bike parked somewhere, I called my daughters who both lived nearby. They drove out, collected me in my ute and one daughter drove my mate home in their car whilst the other drove me in my ute to Cooma Hospital, 110 kms away, and much closer to home, and a friendlier place, and its where my wife works as a pharmacist. I went straight there with one daughter, the other drove home to collect the wife and we were all now in Cooma Hospital. My daughters drove back to Canberra and my wife hung about and had my ute and bike to drive home when she was ready. Then the nurses decided the doc needed to pay me more attention. The swollen arm was the problem, so an ambulance was called and I was carted off to Canberra Hospital getting back there about 24:00, having left there 6 hours before. Scored a bed in the corridor until a ward vacancy became mine about 06:00. My wife collected me the next day, and fortunately with no surgery required. And its ATGATT for me, always has been. Apart from other gear damage, the patella cap was removed from my knee brace on first impact, and then the chip dug through my nylons and into my knee.
