Nerf pectoral latéral

Lateral Pectoral Nerve. The lateral pectoral nerve (also known as the lateral anterior thoracic nerve) is associated with a number of variations but most commonly arises as two branches, one each from the anterior divisions of the upper and middle trunks, although in many cases it does arise directly as a single branch from the lateral cord (Porzionato et al., 2012). The nerve contains …

Due to a communicating branch to the medial pectoral nerve some lateral pectoral nerve fibers pass to and innervate the pectoralis minor. The lateral pectoral nerve also carries nociceptive and proprioceptive fibers. Variant anatomy. The lateral pectoral may have two distinct origins from the anterior divisions of the superior and middle trunks.

The lateral pectoral nerve (lateral anterior thoracic; fasciculus lateralis) the larger of the two, arises from the lateral cord of the brachial plexus, and through it from the fifth, sixth, and seventh cervical nerves. It passes across the axillary artery and vein, pierces the coracoclavicular fascia, and is distributed to the deep surface of the Pectoralis major. It sends a filament to join …

Le nerf pectoral latéral naît du faisceau latéral du plexus brachial et innerve essentiellement le muscle grand pectoral. Il contient des fibres issues des cinquième, sixième et septième nerfs cervicaux. Le nerf pectoral latéral peut avoir une ou deux branches d’origine, et le nerf pectoral médial n’en a qu’une seule [1].

The lateral pectoral nerve is important in the pain response after breast augmentation and mastectomy, and especially in breast implant surgery, when the implant is inserted by the subpectoral route. The pectoral nerves can be anesthetized intraoperatively by the surgeon under direct vision by three injections – one to block the medial pectoral nerve, the second to block the perforating …

Note that pectoralis major heads could be cross innervated by the lateral and medial pectoral nerve, hence the variation and range of root origins for these nerves. Origin of Upper Fibers (Clavicular): Anterior surface of sternal ½ of clavicle. Insertion of Upper Fibers (Clavicular): Crest of greater tubercle of humerus. Insertions of upper fibers are more anterior and caudal on the crest …

To the lateral pectoral nerve, when dissecting in the axilla . Although frank transection of the lateral pectoral nerve is rare, aggressive electrocoagulation of the branches of the thoracoacromial artery and vein can cause adjacent nerve injury. For this reason, minimal dissection is advised in the axilla, primarily using blunt dissection, in the path of dissection to the lateral border of …
