Trephined
Skull © 1992 Scott Lindgren
Trephination
is used to make an intentional entry into the skull in order to allow instruments
to elevate skull fragments and remove blood clots at the site of the injury.
The trephine does not penetrate the brain, and the procedure is more superficial
than it might appear. This skull of a German killed by a brick in a riot in
Baltimore, 1939, shows a trephination hole next to the site of the fracture
and is an example of unsuccessful trephination for a fracture. Shown with
a trephine, mid-nineteenth century. Trephine presented to the Museum by Gabriel
Tucker, Jr., M.D.
