Unusual craniocerebral injuries from nailing.

Three cases of unusual craniocerebral injuries caused by deliberate driving of nails into the head are reported. All injuries were on or near the midline in the parietal area and the nails measured about 10 cm. Two of the patients experienced little pain during the procedure and did not lose consciousness. The extraction of each nail was extremely easy. The only patient who died was admitted in a coma and had meningitis.
