What is this injury?

Thanks to help here I have been able to access my grandmother`s first husband`s service record. 

He Died from wounds "SW left arm"
Any ideas what SW stands for?  It was at Passchendale so I`m prepared for it to be unpleasant

Shrapnel wound would be my best guess

SW as in Severe Wound?

[jane k]

thanks, yes sadly Severe Wound makes sense

I've seen SW defined as Shrapnel Wound in the context of Canadian and Anzac WW1 medical records.

UK forces generally (but not always) used the standardised acronym GSW (gun shot wound) to cover both bullet and shrapnel wounds. But see https://www.greatwarforum.org/topic/231470-medical-abbreviations/

Shrapnel Wound also seems likely.  I`ve seen a description of what was happening on that day and there was an awful lot of shrapnel flying around

My grandfather's records indicate SW in several different instances. He definitely had shrapnel wounds to the legs and groin. Post-WW1 he was in and out of hospitals due to his wounds. He eventually died of bladder cancer.

I would say SW is shrapnel wound plenty of that flying around.  One often sees GSW on military records, that is Gunshot wound.
