How do you fix a quadrilateral space syndrome?
Conservative treatment is often first trialed, including physical exercise modification, physical therapy, and therapeutic massage. In patients unrelieved by conservative measures, surgical decompression of the quadrilateral space may be indicated.
What is Quadrangular space syndrome?
Quadrangular space syndrome (QSS) or Quadrilateral space syndrome is a compressive neuropathy of the axillary nerve (AN) and/or the posterior circumflex humeral artery (PCHA) in the shoulder. The most frequent cause is a fibrous band(s) in the quadrilateral wpace (QS) and/or surrounding muscle hypertrophy.
Where is quadrilateral space?
The quadrangular space (or quadrilateral space) is one of three spaces located in the posterior compartment of the arm, along with the lateral triangular space and medial triangular space.
What is quadrilateral paresthesia?
Quadrilateral space syndrome is an uncommon cause of paresthesia and an underdiagnosed cause of digital ischemia in overhead athletes. Quadrilateral space syndrome can present with neurogenic symp- toms (pain and weakness) secondary to axillary nerve compression.
How many dialogues does a quadrilateral have?
Hence a convex quadrilateral has 2 diagonals. Hence option [b] is correct.
How many edges does a quadrilateral have?
4
Quadrilateral/Number of edges
What runs through quadrilateral space?
Which structures pass through them respectively? The quadrangular space (also known as the quadrilateral space) is an anatomic interval formed by the shaft of the humerus laterally, the long head of the triceps medially, the teres minor muscle superiorly, and the teres major muscle inferiorly.
What is the definition of quadrilateral space syndrome?
Quadrilateral space syndrome (QSS) is a rare disorder characterized by axillary nerve and posterior humeral circumflex artery (PHCA) compression within the quadrilateral space. Impingement is most frequently due to trauma, fibrous bands, or hypertrophy of one of the muscular borders.
How is quadrangular space syndrome a neurovascular disorder?
Pathology. Quadrangular space syndrome is a neurovascular compression syndrome of the posterior humeral circumflex artery (PHCA) and/or the axillary nerve or one of its major branches in the quadrangular space. Quadrangular space syndrome most commonly occurs when the neurovascular bundle is compressed by fibrotic bands within
Where are fibrous bands found in the quadrilateral space?
The axillary nerve innervates the teres minor and deltoid muscles, which are primarily responsible for abduction and external rotation. Characteristic fibrous bands are found within the quadrilateral space, which exacerbate symptoms, particularly pain, elicited by movements associated with the deltoid and teres minor muscles [9,10].
What causes hypertrophy of the quadrangular space?
Quadrangular space syndrome most commonly occurs when the neurovascular bundle is compressed by fibrotic bands within the quadrangular space and/or by hypertrophy of the muscle boundaries. Fibrotic bands form as the result of trauma, with resultant scarring and adhesions.
