Variations include typically of Lateral Thoracic Artery LTA and Posterior Circumflex Humeral Artery PCHA. With the further study of medial support and blood supply of humeral head new techniques and conception are developing.

In twenty-four fresh-frozen cadaver shoulders twelve.
. The study aims to illustrate the medial approach of the proximal humeral fracture through cadaver. In the authors experience the posterior circumflex humeral artery could be used for supercharging the supraclavicular flap. Analysis of 103 flaps used to reconstruct neck scar contractures.
The brachial plexus and the axillary artery of right side had usual anatomy. In one cadaver the posterior circumflex humeral artery PCHA arose from the subscapular artery in one side 10 n1 and from the profunda brachii artery on. Superior thoracic artery 2a 2b.
Our cadaver was a bit roughed up but remember in palmar side. The distal third part gives subscapular artery anterior and posterior circumflex humeral arteries. This inconsistency suggests a greater role for the posterior humeral circumflex artery than has been previously described.
We studied the arterial anatomy and the effect of four-part fractures on the vascularity of the humeral head using barium sulphate perfusion of 16 cadaver shoulders. The triangular space is bounded by the teres minor superior teres major inferior and long head of the triceps lateral. Posterior circumflex humeral artery.
Anatomical and clinical studies of the supraclavicular flap. Middle front left body. The anatomy of the terminal branches of the posterior circumflex humeral artery PCHA has not been described before.
The posterior circumflex humeral artery is one of two circumflex humeral arteries that surround the surgical neck of the humerus. The anterior circumflex humeral artery the posterior circumflex humeral artery the circumflex scapular artery and unnamed muscular branches were given from this pedicle Figures 1 2. G 227AN 420Gl 281B The anterior circumflex humeral artery is typically the smaller of the two arteries.
This artery gives off several muscular cutaneous and articular branches. Posterior circumflex humeral artery. Posterior arm of arm and forearm.
A coincidental variation of the axillary artery. We undertook an investigation to correct this omission. Remove the deep fascia from the muscles on the posterior aspect of the scapula and identify three muscles that contribute to the rotator cuff Figures 41 42 and 43.
Konarik M1 Kachlik D Baca V. The posterior circumflex humeral artery passes lateral to the long head of the triceps muscle traverses the quadrangular space. Circumflex scapular artery Arteria circumflexa scapulae The circumflex scapular artery is the largest terminal branch of the subscapular arteryIt courses through the posterior aspect of the shoulder within the infraspinous fossa of the scapula.
The posterior circumflex humeral artery passes directly medial and posterior to the humerus surgical neck. During dissection of the right upper limb of the cadaver of a 70-year-old male a common trunk was observed arising. The axilla of a 65-year-old embalmed female cadaver was routinely dissected for educational purpose in the Department of Anatomy AIIMS New Delhi India.
It winds around the surgical neck of the humerus and is distributed to the deltoid muscle and shoulder-joint anastomosing with the anterior humeral circumflex and deep artery of the. The major trunks of these vessels and nerve appear on the medial side of the neck of the humerus and encircle the humerus dorsally in a lateral direction radiating branches into the. It arises from the third part of the axillary artery and supplies the shoulder joint and a number of its associated muscles.
The present case has been reported to document the variation of LTA and PCHA. The main arterial supply to the humeral head was via the ascending branch of the anterior humeral circumflex artery and its intraosseous continuation the arcuate artery. Far left body.
The subscapular anterior and posterior circumflex humeral arteries originate from the third part of axillary artery. Despite the expansion of arthroscopic surgery of the shoulder the open deltopectoral approach is increasingly used for the fixation of fractures and arthroplasty of the shoulder. Carefully probe in the underlying fat and connective tissue to locate the axillary nerve and the posterior circumflex humeral artery and vein emerging from the quadrangular space to enter the deltoid.
After giving rise to the anterior circumflex humeral artery trifurcated into a branch that coursed distally the posterior circumflex humeral artery and the subscapular artery. Discussion The limbs are formed by the somites which bring their. Srimathi reported a case in which second part of Axillary artery gave a common trunk from which thoracoacromial lateral thoracic subscapular and posterior.
The treatment of complex 3- and 4-part proximal humeral fractures has been controversial due to numerous postoperative complications. We hypothesized that the posterior humeral circumflex artery provides a greater percentage of perfusion to the humeral head than the anterior humeral circumflex artery does. The right axilla of a male cadaver 1.
It is not uncommon to find variations in the branching pattern of the axillary artery. Compared to the anterior circumflex humeral artery the posterior circumflex humeral artery is usually of a larger caliber. The posterior circumflex humeral artery occasionally arises from the subscapular artery.
So above scapula and what RTC is up there. Supraspinatus superior to the scapular spine Infraspinatus inferior to the scapular spine. Her example was right in the GH joint on cadaver.
The latter subdivided into the circumflex scapular artery a. The subscapular anterior circumflex and posterior circumflex arteries arise from the third part of the axillary artery. Supraclavicular flaps are reliable but vascular anomalies exist.
The brachioradial artery and the aberrant posterior humeral circumflex artery passing under the tendon of the latissimus dorsi muscle. Sets found in the same folder. Posterior circumflex humeral artery.
Many of its branches may arise by a common trunk or a branch of the named artery may arise separately 2. 2 Although variations in the branching pattern of the axillary artery are common a rare anatomical variation of the origin of the subscapular and posterior circumflex humeral arteries from the axillary artery combined with an anomalous relationship between. The axillary artery presents abnormalities in its origin and course and a variable branching.
The posterior humeral circumflex artery arises from the third part of axillary artery at the lower border of the subscapularis and runs posteriorly with the axillary nerve through the quadrangular space. Remember we name the arteries for the structures they supply where they go even if they do not follow the typical branching pattern illustrated in the atlas. A rare case of axillary artery bifurcation and branching was observed in a 60-years-old European male cadaver of Greek origin.
The circumflex scapular artery and vein traverse this space. The axillary nerve and posterior circumflex humeral vessels traverse the quadrangular space. The right axillary artery at the second part was bifurcated into a superficial and a deep brachial artery.
