The Supinator syndrome: An anatomical and clinical study

Abstract

The interosseus posterior syndrome appears in two forms:

1.	the paralytical interosseus posterior syndrome,
2.	the painful (afferent) interosseus posterior syndrome.

We report in this investigation about 12 operated patients with painful interosseus posterior syndrome. The intraoperative findings in the arcade of Frohse are compared with the findings we made at the preparation of 10 recently deceased. It was especially significant, that we found in 10 of our 12 cases intraoperatively a tendinous type of arcade. In our directioned cases we encountered this type of tendinous arcade in only 2 of 10 cases.

Based on these findings we are of the opinion that the tendinous arcade of Frohse is an important factor in the development of the interosseus posterior syndrome.
