Assessment of the prognostic value of horner syndrome in perinatal brachial plexus palsy.

The aim of this study was to evaluate the prognostic value of Horner syndrome as an indicator of preganglionic injuries of the lower part of the brachial plexus. The study investigated 18 cases of children with perinatal brachial plexus injury and coexistent Horner syndrome. The following data sets were analyzed: the degree of severity of the brachial plexus injury, the results of imaging examinations, the intraoperative view, the kind of operative treatment and the resultant hand function. On the basis of a clinical material analysis, it was established that Horner syndrome accompanying upper and upper-middle brachial plexus injuries has no prognostic importance. In total injuries the presence of this syndrome is not a definite proof of preganglionic injury to the C8-Th1 roots of the spinal nerves.
