The complete or partial absence of the pectoralis muscle is the malformation that defines Poland syndrome. It can be treated by inserting a custom implant designed by CAD (computer aided design). [11] A 3D reconstruction of the patient's chest is done using an implant shaped from a medical scan and designed to be perfectly adapted to the ...
Beneath the pectoralis major is the pectoralis minor muscle. The pectoralis major arises from parts of the clavicle and sternum , costal cartilages of the true ribs , and the aponeurosis of the abdominal external oblique muscle ; it inserts onto the lateral lip of the bicipital groove .
CT with IV contrast showing enlargement and heterogeneous hypodensity in the right pectoralis major muscle. A focal abscess collection with gas within it is present medially. There are enlarged axillary lymph nodes and some extension into the right hemithorax. Note the soft tissue and phlegmon surrounding the right internal mammary artery and vein.
After fracture of the clavicle, the sternocleidomastoid muscle elevates the medial fragment of the bone. The trapezius muscle is unable to hold up the distal fragment owing to the weight of the upper limb, thus the shoulder droops. The adductor muscles of the arm, such as the pectoralis major, may pull the distal fragment medially, causing the ...
Pectoralis minor syndrome (PMS) is a condition related to thoracic outlet syndrome (TOS) that results from the pectoralis minor muscle being too tight. [1] PMS results from the brachial plexus being compressed under the pectoralis minor [2] while TOS involves compression of the bundle above the clavicle. In most patients, the nerves are ...
Pectoralis minor is a thin, triangular muscle located beneath the pectoralis major. It attaches to the ribs, and serves to stabilize the scapula, the large bone of the shoulder. The pectoral fascia is a thin layer of tissue over the pectoralis major, extending toward the latissimus dorsi muscle on the back.
The standard location for thoracostomy is the triangle of safety. This is an anatomical triangle. The borders of which are; the anterior border of the latissimus dorsi, the lateral border of the pectoralis major muscle, a line superior to the horizontal level of the nipple (or 5th intercostal space), with the apex being below, or at, the axilla. [5]
It originates from the axillary artery and follows the lower border of the pectoralis minor muscle [1] to the side of the chest to supply the serratus anterior muscle, [2] pectoralis major muscle [3] and pectoralis minor muscle, [4] and sends branches across the axilla to the axillary lymph nodes and subscapularis muscle.
