Duplicated axillary arch muscles arising from the latissimus dorsi
نویسندگان
چکیده
Many origins and insertions of an axillary muscular slip (also known as Langer's or axillary arch muscles) have been documented previously. In this report, we found duplicated axillary arch muscles (two variant muscular slips) originating from the inferolateral border of the right side latissimus dorsi muscle. Obviously, these axillary arch muscles can be distinguished as short and long muscular strips. While the origin was the same, the short muscular slip inserts into the fascia covering on the pectoralis minor, whereas the longer one inserts on/into the aponeurosis of pectoralis major. For the surgery in the axillary region, this rare variation should be considered a cause of surgical interventions.

An axillary arch muscle – a case report
Introduction A number of accessory muscle slip cases in the axilla arising from latissimus dorsi, pectoralis major, ribs and costal cartilages have been reported by different authors [1]. These accessory muscle slips in the axilla have been described under variety of names (e.g., chondro-epitrochlearis, dorsoepitrochlearis, etc). These variant bundles are commonly referred to as “axillary arch”...
متن کاملInnervations of Muscular Axillary Arch of Latissimus Dorsi by Pectoral Loop
Latissimus Dorsi is a Hat and triangular muscle that covers the lumbar region and the inferior part of the thorax.The innervation of this muscle is from the thoracodorsal nerve (C6, C7, CS), a branch of posterior cord of the brachial plexus. This report deals with the dissection of the axillary region of a male cadaver. In this cadaver, we observed a muscular axillary arch which was innervated ...

Best-known variant structure of the axillary components of men is a muscular or fibro-muscular slip extending from the latissimus dorsi muscle to the tendons, muscles or fasciae of the superior part of the humerus. This variation had first described by Ramsay in 1795 and confirmed by Langer in 1864 and named as axillary arch of Langer. Although different frequencies have been reported from cada...
متن کاملAn unusual case of axillary arch bridging across the anterior and posterior axillary folds in the distal part of axilla
Introduction Axillary arch is an additional muscle bundle of various dimensions extending from latissimus dorsi in the posterior fold of the axilla, to the pectoralis major in the anterior fold, to the short head of the biceps brachii or to the coracoid process [1, 2]. Ramsay, in 1795, described the axillary arch for the first time. He gave the description of a muscle bundle connecting pectoral...
متن کاملThe axillary arch: anatomy and suggested clinical manifestations.
The purpose of this commentary is to describe bilateral anomalous bands of the latissimus dorsi muscle observed in an 81-year-old male embalmed cadaver, and to discuss the possible clinical implications of this anomaly. The musculotendinous bands tautened and compressed the underlying axillary vessels, and the musculocutaneous, median, and ulnar nerves during passive abduction/external rotation...
