An acromioplasty involves shaving of the undersurface of the acromion. The acromion is a projection of bone extending from the shoulder blade out over the top of the shoulder joint and provides attachment for muscles around the shoulder including the trapezius and deltoid muscles.
The reason DaimlerChrysler's Global Electric Motorcars (GEM) subsidiary can be in business is the National Highway Traffic Safety Administration's 1998 creation of the Low Speed Vehicle (LSV) standard. LSV is sort of a cheat, a way to make electric vehicles viable by eliminating every obstacle in their way.
The big news on the 2002 GEM is the bounce in horsepower of the 72-volt, GE-built DC motor from 3.5 to 5.0, as well as a new gearbox, a revised interior, and new fiberglass doors. On a percentage basis, that extra power is the same as a Corvette moving from 350 to 500 horsepower!
