Quadrangular, axillary nerve injury Everything You Need To Know - Dr. Nabil E

Dr. Ebraheim’s educational animated video explains about the Quadrangular Space. note: Error in the second 21 of this video, the muscle labeled as: Teres Major is the Infraspinatus. Anatomy •Teres minor muscle •Teres major muscle •Triceps muscle Quadrangular syndrome is compression of the posterior humeral circumflex artery and/or the axillary nerve within the quadrangular space. Compression of the structures within this pace may lead to pain and paresthesia. There may also be weakness of the deltoid and teres minor muscle. This syndrome is usually caused by trauma, fractures, dislocation, tumors, or hematoma. May also be due to sports, which require overhead activity such as throwers. The area of the quadrilateral space decreases in size when the arm is abducted. This may lead to the compression of the structures in the quadrangular space as the teres major and minor muscles come together. Clinical signs •Paresthesia and hypesthesias around the shoulder and the upper arm. •Deltoid atrophy •Tenderness over the quadrilateral space. MRI arteriogram (MRA) will show the status of the artery and the condition of the muscles (Atrophy of the deltoid or teres minor) May show cysts, ganglia, or tumors. Arteriogram can also be used and may show compression of the posterior humeral circumflex artery Treatment •Physical therapy •Corticosteroid injections •Surgical decompression of the nerve after failure of trial of conservative treatment for 6 months (posterior approach is utilized).
