[QUOTE] It appears that Sonny decided he needed to modify the suspension on his scooter, so he stripped the shock off and set to. You know the bit where it says "Do Not Dismantle" in big letters, with hazard markings and all? Well, he dismantled it - or somehow, released the gas in the shock: nitrogen, I assume. As the gas made a break for atmosphere it would have been in a big hurry and expanding on the way - and his little finger was obstructing its path. The top joint of the offending digit is now blue, swollen "hard as a marble" and cold to the touch. Oh, and it hurts like fuck, apparently.[/QUOTE] Most probably a injection injury caused by a jet of pressurized oil. Treatment must be done immediately to avoid tissue damage and nechrosis but most ER staff is completely clueless about this kind of injuries. [QUOTE] They had a trip to the hospital yesterday, but as there wasn't a suitable surgeon on duty, they were sent home with instructions and painkillers. They're going back today, and he'll come home a little lighter, having had it amputated.[/QUOTE] As expected due to the lack of proper treatment. He can be happy having lost only a fingertip, injected oil can migrate and cause big damage far from the injection point. [QUOTE] It strikes me there's a cautionary tale here and it had never occurred to me that this sort of injury might result from dicking about with suspension. Let's go careful out in that workshop, eh?[/QUOTE] This kind of injury can be produced by diesel injectors, grease guns, paint guns, etc. Solvent/paint ones are particularly nasty.
