What is deltopectoral groove?
The deltopectoral groove is located between the superolateral aspect of the pectoral region and the deltoid muscle. It runs obliquely from superomedial to inferolateral and contains the cephalic vein which at the upper margin of the groove dives deep to pierce the clavipectoral fascia and enter the axillary vein.
What is a deltopectoral approach?
The deltopectoral approach [10, 44] is the most commonly used approach for shoulder arthroplasty. It provides excellent humeral exposure and preserves the deltoid origin, making it an ideal approach for hemiarthroplasty. The approach begins with identification of the coracoid process.
Where is the deltopectoral interval?
Exposure of deltopectoral interval An interval is developed between the pectoralis major and the deltoid, preserving the cephalic vein which can be taken either laterally or medially.
What are the structures passing through deltopectoral triangle?
The deltopectoral triangle (again, blue arrow above) is important because it: Contains the cephalic vein, pectoral nerves and pectoral artery (a branch of thoracoacromial trunk). All are important structures! Provides surgical access to the genohumeral (shoulder) joint, sparing adjacent muscles.
What passes through quadrangular space?
Anatomy. The axillary nerve is a branch from the posterior cord of the brachial plexus. It travels along the subscapularis muscle and enters the axilla before passing posteriorly through the quadrangular space.
What nerve is in the deltopectoral triangle?
The deltopectoral triangle (again, blue arrow above) is important because it: Contains the cephalic vein, pectoral nerves and pectoral artery (a branch of thoracoacromial trunk).
What is in the Clavipectoral triangle?
It contains the cephalic vein, and deltopectoral fascia, which is a layer of deep fascia that invests the three structures that make up the border of the triangle. The deltoid branch of the thoracoacromial artery also passes through this triangle, giving branches to both the deltoid and pectoralis major muscles.
What passes through the deltopectoral groove?
The deltopectoral groove is an indentation in the muscular structure between the deltoid muscle and pectoralis major. It is the location through which the cephalic vein passes and where the coracoid process is most easily palpable.
What vein lies in the deltopectoral groove?
The cephalic vein
The cephalic vein is located in the deltopectoral groove (Fig. 26-12), which is formed by the reflections of the medial head of the deltoid and the lateral border of the greater pectoral muscles. The groove can be precisely located by palpating the coracoid process of the scapula.
What are the boundaries of quadrangular space?
The quadrilateral, or quadrangular space, is located over the posterior scapular and subdeltoid regions. The boundaries include the teres minor superiorly, the long head of the triceps medially, the teres major inferiorly, and the surgical neck of the humerus laterally (Fig.
What are the borders of the deltopectoral triangle?
The clavipectoral triangle (also known as the deltopectoral triangle) is an anatomical region found in humans and other animals….It is bordered by the following structures:
- Clavicle (superiorly)
- Lateral border of Pectoralis Major (medially)
- Medial border of Deltoid muscle (laterally)
