"Don't wrist guards lead to injury further up the arm?
O.M.G!!! This is an old chestnut with very little actual basis in fact but it still rears its ugly head far too frequently! In 1995 (15+ years ago now), Cheng et al reported four cases where skaters (not snowboarders) wearing wrist guards sustained open forearm fractures immediately proximal to the wrist guard. They hypothesised that the guard could transfer the energy of impact from the hand to the mid-forearm level. Their report did not describe the splints each individual was using or if they were fitted properly. Whilst it may sound a cautionary note, very few other case reports have been forthcoming out of the many thousands of skating injuries occurring every year.
You also have to remember that inline skating and snowboarding are different sports. Skaters usually fall onto concrete surfaces (consequently with a more abrupt stop involved). I am only aware of two individual cases where snowboarders wearing guards have sustained upper arm fractures, possibly as a result of wearing a guard. This must be compared to the thousands of potential wrist injuries that guards have prevented or reduced in severity. Subsequent biomechanical studies do not support Cheng’s theory and, in fact, demonstrate that one of the protective effects of guards is to dissipate impact energy safely throughout the device without increasing the forces at any one spot."
Quoted from www.ski-injury.com
, a site that does not sell ANY brand of wrist guard, unlike Level.
The line you quote references numbers for the reduction of wrist injuries from wearing wrist guards (including Level) versus not wearing any wrist guards. It does not specifically give evidence of fractures "moving up" the arm where a wrist guard ends.
From Level's website: "Standard wrist guards frequently push the fracture farther up the forearm". Well, how frequently? If they can give specific ratios for improvement in wrist injury reduction from their study, they should be able to provide similar numbers for the claim about injuries moving up the forearm. Notably, they don't.
And yes, the original quote is to what I was referring in my post that you reference.
