ABSTRACT
Obstetrical brachial plexus palsy invariably involves the upper roots. The natural
history of the injury shows that if the condition is left untreated, spontaneous reinnervation
that occurs in a variable degree in these patients leaves characteristic deformities
of the shoulder and elbow. Common sequelae are the internal rotation and adduction
deformity of the shoulder, and elbow flexion contractures. Early microsurgical reconstruction
of the affected plexus leads to more rewarding overall function of the shoulder and
elbow, but residual deformities might appear again, similar to the ones noticed in
untreated cases, that are even less serious. Thus, secondary procedures are mandatory
to reanimating the shoulder and elbow, and especially to provide adequate abduction
and external rotation of the shoulder and a more neutral appearance of the elbow regarding
flexion-extension equilibrium.
