Subscapular artery, the largest branch of axillary artery, runs along the lower border of the subscapularis and ends near the inferior angle of the scapula. It supplies a large branch, the circumflex scapular artery; which goes through upper triangular intermuscular space, winds round the lateral border of scapula to goes into infraspinous fossa runs along the lower border of subscapularis and ends near the inferior angle of the scapula. It gives a large branch, the circumflex scapular artery , which passes through upper triangular intermuscular space, winds round the lateral border of scapula to enter infraspinous fossa. also gives many small branches 1.

The current report presents a case of a giant neurothekeoma with a partially-formed capsule, scapula erosion and unclear biological behavior, which originated in the intermuscular space between the left trapezius muscle and scapula The scapular and circumflex arteries. (Triangular interval is visible but not labeled.) The triangular interval (also known as the lateral triangular space, lower triangular space, and triceps hiatus) is a space found in the axilla. It is one of the three intermuscular spaces found in the axillary space

spinatus intermuscular planes or subscapularis muscle splits without rotator cuff tenotomies. Introduction Fractures of the scapula are relatively uncommon injuries, making up 3% to 5% of all fractures of the shoulder girdle and <1% of all fractures.1,2 They are usu-ally the result of high energy trauma, and more than 50 The patient was installed in a left lateral decubitus position. The scapula was approached by a combined posterior approach (): a horizontal incision along the spine of the scapula and the posterior border of the acromion to extend beyond the postero-external angle of the acromion, associated with a direct posterior intermuscular approach between the infraspinatus muscle and the teres minor. The quadrangular space is an intermuscular space through which the axillary nerve and posterior circumflex humeral vessels pass through backwards to encircle the surgical neck of the humerus. It is bounded above by subscapularis and teres minor and below by teres major

A quick summary, by points: Thoracic outlet syndrome is usually caused by extremely weak scalenes and posturally depressed clavicle.

The medial intermuscular septum gives partial attachment to the triceps and brachialis muscles. Muscles. The pectoral muscles are active in flexion, adduction and medial rotation of the shoulder joint ( pectoralis major) and assist in depressing and protracting the scapula ( pectoralis minor) Lipomas are benign tumors of mature adipose tissue which can occur in subcutaneous, intramuscular, intermuscular, parosteal, and intraosseous compartments. Parosteal lipoma is a rare type of lipoma, accounting for less than 0.1% of primary bone neoplasms and 0.3% of all lipomas. Parosteal lipomas commonly arise in the femur and extremities. Around 150 cases have been reported in.

Peripheral nerves, particularly in the upper extremities, are vulnerable to entrapment in narrow anatomic spaces and compression by mass lesions (, 26). One role of MR imaging in the setting of suspected peripheral nerve injury is detection of a surgically correctable cause of nerve compression such as a bone spur or ganglion cyst ( , Fig 10 ) The biceps arm muscle is more superficially located, and under it lie the beak-brachial (proximal) and brachial (distal) muscles. Both layers of muscles are separated by a deep leaf of the fascia of the shoulder, under which passes the musculocutaneous nerve. In the medial groove of the biceps brachii of the shoulder, there is a vascular-neural. spaces in scapular region. by | Jan 24, 2021 | News | 0 comments | Jan 24, 2021 | News | 0 comment

  1. The quadrangular space is an intermuscular space, located immediately below the shoulder joint. It is bounded above by the subscapularis and capsule of the shoulder joint and below by the teres major muscle. It is bounded medially by the long head of the triceps and laterally by the surgical neck of the humerus
  2. or, and gives a branch to the subscapular fossa, and another branch to the infraspinous fossa, both of which take part in the anastomoses around the scapula. 5. Anterior Circumflex Humeral Arter
  3. An essential prerequisite for a successful sentinel lymph node biopsy (SLNB) procedure is an accurate map of the pattern of lymphatic drainage from the primary tumor site in each patient. In melanoma patients, mapping requires high-quality lymphoscintigraphy, which can identify the actual lymphatic collecting vessels as they drain into the sentinel lymph nodes

The triangular interval (also known as the lateral triangular space, lower triangular space, and triceps hiatus) is a space found in the axilla. It is one of the three intermuscular spaces found in the axillary space. The other two spaces are: quadrangular space and triangular space Fractures of the scapula are rare and usually associated with high-energy trauma. The unfavorable scapular anatomy, combined with the complexity of the approaches for fracture fixation, make the treatment challenging, even for experienced surgeons. Furthermore, the literature is controversial regarding surgical indications and rationale for treatment. The present review article was designed to.

The term snapping scapula has been used to describe the clinical scenario of tenderness at the superomedial angle of the scapula, They identified two spaces: a serratus anterior space between the ribs and the serratus anterior, and a subscapularis space between the serratus anterior and the subscapularis. Because of its intermuscular. It is one of the three intermuscular spaces found in the axillary space. Where is the triangle of auscultation? Dorsally on each side of the trunk, the triangle of auscultation is the area bounded by: medially: the lateral border of the inferior part of trapezius. laterally: the vertebral border of the scapula. inferiorly: the superior border.

The mass measured 7.3 x 9.0 x 5.2.

The exact cause of ganglion cysts in shoulder is not known. However, it is believed to be caused due to trauma which may damage the tissues in the shoulder joint or the lining of the tendon. Actually it is like a balloon which grows out of the joint capsule or the tendon lining. It has a stalk through which fluid enters in the lump The practice of regional anesthesia is inconceivable without sound knowledge of the functional regional anesthesia anatomy.
