The infraspinatus muscle arises in the Infraspinate fossa of the shoulder blade. This is located on the outside of the bony shoulder blade. He sits on the big hump (Greater tuberosity) of the humerus.
Because of this course, its main task is external rotation. In addition, he lifts the entire upper extremity outward with his arm raised. When the arm is lowered, the infraspinatus muscle leads the arm inwards.
Furthermore, the tendon of the muscle radiates into the joint capsule of the shoulder and thus strengthens and tensions the capsule.
The infraspinatus muscle is part of the Rotator cuff and can thus with one Rotator cuff tear get injured and lose its function.
The most common cause of one Rotator cuff rupture is an overuse of the Shoulder muscles and thus also the infraspinatus muscle.
But also a dislocation of the shoulder joint (dislocation) or applying strong force to the shoulder can tear the muscles. If the infraspinatus muscle is affected, the patient initially has strong pain. In this case, the shoulder is no longer properly stabilized and takes on an unusual position. In the case of the infraspinatus muscle, the Shoulder rotated inward and can tilted forward slightly appear. This is due to the actual course of the muscle, its origin and insertion.
Since the infraspinatus muscle is primarily the External rotation the patient can only rotate the arm externally with great difficulty and with great pain. Furthermore, the infraspinatus muscle moves the arm away from the body and also towards the body. These movements are also through one Loss of function highly limited.
Other diseases, such as tendon inflammation or shoulder dislocations, are usually not caused by the infraspinatus muscle.

Who am I?
My name is Carmen Heinz. I am a specialist in orthopedics and trauma surgery in the specialist team of .
The shoulder joint is one of the most complicated joints in the human body.
Therefore, the treatment of the shoulder (rotator cuff, impingement syndrome, calcified shoulder (tendinosis calcarea, biceps tendon, etc.) requires a lot of experience.
I treat a wide variety of shoulder diseases in a conservative way.
The aim of any therapy is treatment with full recovery without surgery.
Which therapy achieves the best results in the long term can only be determined after looking at all of the information (Examination, X-ray, ultrasound, MRI, etc.) be assessed.
