Langer’s Axillary Arch ? Case Presentation and Literature Overview

Langer’s axillary arch is an important anatomical variant of the shoulder region, connecting the latissimus dorsi and the pectoralis major muscles. Due to its frequency, clinicians should be aware of this variant as misidentifications could lead to severe complications in patient treatment. The presented axillary arch was identified in a 67 years old specimen. Its innervation by the lateral pectoral nerve and blood supply by the subscapular artery could be preserved. In conclusion, this case report and literature overview point out a clinical important anatomical variant, Langer’s axillary arch. Its misidentification can lead to wrong diagnoses and massive surgical complications, which could easily be avoided by intimate anatomical knowledge of the axillar region and its most frequent variants.
