The Silver Wand
When Apollo whisked Aeneas off the field of battle before Troy, he
healed the hero's shattered thighbone in a matter of minutes. Without a
god at the bedside, the process takes three to six months, and sometimes
it fails. If the bones didn't knit, the limb formerly had to be amputated
after the victim had suffered for a year or more.
It was only in 1972 that I felt ready to try electrical stimulation of
human bone growth in such cases. Zachary B. (Burt) Friedenberg, Carl
Brighton, and their research group at the University of Pennsylvania had
already reported the first successful electrical healing of a nonunion two
years before, but to avoid possible side effects we felt we must duplicate
the natural signal more closely than they had, and we didn't know
enough until after our work on rat leg regeneration. Like Friedenberg we
decided to place a negative electrode between the bone pieces, but using
a much smaller current and a silver electrode rather than stainless steel.
We thought silver would be less likely to react chemically with the
tissue and better able to transmit the electrical current. At that time we
were treating a patient whose condition seemed to demand that we try
the new procedure.
Minus for Growth, Plus for Infection
Jim was in bad shape. Drafted during the Vietnam War, he'd been a
reluctant, rebellious soldier. He survived his tour in Nam and was trans-
ferred to an Army base in Kansas late in 1970. On New Year's Eve he
