History of Erb's Palsy
A midwife first described brachial plexus injuries in 1779 by the paralysis
of the arms muscles due to injury of its nerves in the neck. Described
was a series of infants with injury to the upper part of their plexus telling
of the characteristic posture of the hand, first called the policemans
tip and then the porters tip. These terms were referring to the arm
extended at the side and internally rotated at the shoulder so that the
palm projects outward and flexion at the wrist.
Erb was first reported around the same time that brachial plexus injuries
were being noted and Erb and Duchenne have been associated to this particular
form of brachial
plexus palsy as it is referred to as Erbs-Duchennes palsy.
Later on someone by the name of Klumpke described the clinical picture
of injury to the lower plexus. It was observed to cause paralysis of the
hands muscles and as associated dilation of the eyes pupil
on the side of the injury. Klumpkes name was associated to this particular
form of brachial plexus palsy when observed in infants and continues to
be called Klumpkes palsy.
Duchenne recommended in the 1870s treating Erbs palsy with
electrical stimulation of the paralyzed muscles. The Erbs palsy treatment
was very uncomfortable to the child and did not become a favorable form
of treatment. Different forms of splinted positions were then recommended
as to avoid the secondary complications due to progressive muscle contracture.
Other forms of Erbs palsy treatments were tried with varying degrees
of success to help the arm deformity associated to brachial plexus, including
tendonotomies, cutting of contracted muscle tendons to gain additional
movement blocked by the contracted muscle, capsulotomies, cutting of capsule
of a frozen joint, and rotational osteotomies, cutting through the bone
of the upper arm and rotating it into a better positioning and fixating
it with a plate.
In 1903 a man by the name of Kennedy was the first to describe surgical
exploration of 3 infants necks that had sustained injury to the brachial
plexus. Kennedy found injured C5 and C6 roots in all of the babies and
resected the zone of injury to the nerves and sewed the cut ends back together.
Kennedy found the surgical brachial plexus exploration to be encouraging.
Clark followed up with a report in 1905 that found similar findings as
well as a 29% mortality rate associated with the brachial plexus surgery.
Later, in 1920, a group of 70 infants endured the brachial plexus surgery
with only one death resulting from the surgery.
The surgery on the brachial plexus appeared to be a break through until
1922 when Bentzon advised against surgery because he found the outlook
for the infants untreated to be good and the published outcomes of the
infants who had been through brachial plexus surgery as unimpressive. Sever
released a review in 1925 of 1,100 infants that he had treated and concluded
that many of the infants who had brachial plexus surgery had very little
gain. Sever felt that physiotherapy and bracing were more beneficial than
the brachial plexus surgery. Then in 1930 Lauwers concluded that the morbidity
and mortality that was associated to the brachial plexus surgery was excessive
and should be avoided. After all these conclusions from various people,
brachial plexus surgery was abandoned.
A report in 1980 by Gilbert brought up brachial plexus surgery once again.
In the mid-1980s Gilberts group was supporting the surgical
exploration of any infant that showed no brachial plexus movement at three
months after birth. Every case that he saw he found the injury requiring
excision of injured nerve tissue and grafting. When he analyzed his results
of 178 children two years following brachial plexus surgery, he found that
the children experienced one grade higher of improvement than compared
to a non-brachial plexus surgery child on average. Since then many different
groups have had positive regard for brachial plexus surgery and it is still
being performed on Erbs palsy injuries today.
