Abstract: Thoracic outlet is a syndrome resulting from compression of neurovascular structures that pass through the outlet. Neurogenic thoracic outlet syndrome is the most frequent category, 90% of cases characterized by weakness and paresthesia of the upper limb. In the presence of this clinical case with thenar and hypothenar atrophy, it is called Gilliat-Sumner Hand. In this case, we describe a clinical case of Gilliat-Sumner hand as a result of a hypertrophic transverse apophysis of C7, which was surgically treated and followed up for more than one year.
