The Infraspinatus and Teres Minor Muscles
•They take origin from the infraspinatus fossa and dorsolateral border of the scapula, respectively, and insert onto the greater tuberosity of the humerus •The suprascapular nerve innervates the infraspinatus, and the axillary nerve supplies the teres minor. •These muscles externally rotate the humerus and stabilize the G-H in concert with the SP &SSc

• Arm is abducted 60°and forward flexed 15° • Traction never exceeded 3 kg
LATERAL DECUBITUS
北京积水潭医院运动医学中心
Lateral Decubitus
Advantage
z
Access to the anterior, posterior, superior, and inferior labrum is easier Visibility is improved when performing multidirectional instability, SLAP, or Bankart injury Decreased risk of cerebrovascular ischemic event during intraoperative hypotension
北京积水潭医院运动医学中心
MGHL
originates from the glenoid labrum below the SGHL and inserts just medial to the lesser tuberosity It often crosses and blends into the subscapularis tendon present in only 85% of shoulders
“upright, anatomic”
the patient is flexed 60° at the waist

Advantage
z z z z
similar to open surgery, minimizes spatial disorientation conversion to open surgery is easier patients tolerate the sitting position better performing arthroscopy solely under the interscalene block without any supplemental sedation lower incidence of nerve palsy

Rotator interval
z
a triangular area that is made up of fibrous elements and bordered by the upper margin of the subscapularis tendon and anterior aspect of the supraspinatus. Within the interval lie the CHL(superficially ), the biceps tendon, and the SGHL (internal pulley at the floor)
