Gee, this guy Spies has had injuries I've never heard of.
"Arm pump"?
At least he had his teeth taken care of.

Arm pump, as I understand it, is the development of the forearms due to
increased musculature which inhibits blood flow. When braking extremely hard
on a roadracing motorcycle, the arms bear enormous pressure from the
deceleration G-forces. This happens 10-15 times/lap in a race. The symptoms
of arm pump are numbing of the hands, leading to loss of hand strength and
more importantly, feel of the brakes and front end of the motorcycle. This
is bad. From the little I've read on the subject, the surgery unrestricts
the forearm muscles by cutting away a sheath around the muscles.

It's officially referred to as "functional chronic compartment
syndrome", and it does involve cutting the facia sheath around the forearm
muscles. What I've seen on it seems to point toward about 5 or 6 weeks of
recovery/rehab, but many riders want to come back sooner than that
(surprise...). It is pretty common in the motocross world, too.
(Apparently, jackhammer operators get it, too.) This used to be a problem
in GP road racing until the development of the carbon brakes. But now that
the bikes are heavier and the throttle needs to be blipped for downshifts,
it has made a comeback.
