Timeline: Pretty much present-day. 2016 or so.
We have a middle-aged man in decent health but not-so-great physical shape trying to climb up an elevator shaft after the car was wedged between floors. He's using a rope, slips, tries to hang on, wrenches his shoulder in the process and falls about 5-8 feet to land on the roof of the elevator car, which then falls about 10-12 feet more.
I want him to survive and not be permanently disabled. Besides the wrenched/dislocated shoulder, bruises etc., probably a concussion, what else would be believable?
