Langer's axillary arch is usually asymptomatic and difficult to detect preoperatively. When present, it is important for surgeons operating in the axillary region, to identify correctly the relevant anatomy. Simple surgical division is curative and necessary in order to achieve exposure of the axillary contents, lymphatic dissection, and neurovascular preservation.

Article Synopsis
- * This anatomical variation is significant due to its low occurrence and the need for surgeons to be aware of it during procedures involving the axillary region.
- * Lack of knowledge about the dorsalis major muscle arch can lead to complications during surgeries like axillary curage or breast reconstruction using a dorsalis major flap.

Article Synopsis
- - Weninger et al. (2023) conducted a large-scale study using 400 axillae from 200 unembalmed cadavers, identifying the axillary arch (AA) in 27 axillae and describing its composition as either muscular, connective tissue, or a combination of both.
- - The study found that in 63% of cases, after moving the arm, the AA contacted the neurovascular axillary bundle, highlighting its clinical significance.
- - The authors commend the research for its detailed illustrations and contribution to medical literature, while also questioning the definition and historical context of the axillary arch as described by Langer in 1846.

The axillary arch muscle, also called Langer's muscle, axillopectoralis, or pectodorsalis, is a muscular variation of the latissimus dorsi muscle. During a standard anatomical dissection, the axillary arch muscle was found bilaterally. On both sides it originated from the latissimus dorsi as a muscle belly.

Connective or muscular tissue crossing the axilla is named axillary arch (of Langer). It is known to complicate axillary surgery and to compress nerves and vessels transiting from the axilla to the arm. Our study aims at systematically researching the frequency, insertions, tissue composition and dimension of axillary arches in a large cohort of individuals with regard to gender and bilaterality.
