Portland, OR -

A woman who was trapped outside for 18 hours at Molalla with her hand stuck under the hood of a pickup truck has had the hand amputated.

Doctors couldn't save Joan Zuber's hand and had to amputate Saturday.

Her daughter, Heather Zuber, told KGW reports her mother is in good spirits, talking about recovering and resuming her activities.

A Molalla Fire District spokesman says the woman in her 70s was working on her truck's battery Wednesday afternoon when the hood slammed on her hand. She was trapped until late Thursday morning when her cries for help were heard by neighbors on horseback in the rural community about 25 miles south of Portland.

Unable to pull away from the truck, Zuber survived overnight temperatures in the 30s and light snow.
