What is rotator interval?

What is rotator interval?

The rotator interval describes the anatomic space bounded by the subscapularis, supraspinatus, and coracoid. This space contains the coracohumeral and superior glenohumeral ligament, the biceps tendon, and anterior joint capsule.

Does ultrasound show rotator cuff tear?

Shoulder ultrasound is consistently used in the assessment of rotator cuff and is as accurate as magnetic resonance imaging in the detection of rotator cuff tear. It can be used as a focused examination providing rapid, real-time diagnosis, and treatment in desired clinical situations.

What can show up on a shoulder ultrasound?

Ultrasound scans are an excellent way of assessing any possible inflammation, calcium deposits and any tears to the tendons of the rotator cuff. An ultrasound scan also has the advantage that it can assess the shoulder as it moves.

What structure passes through the rotator cuff interval?

Anatomical section through the rotator interval showing the superior glenohumeral ligament (SGHL), the medial (MCHL) and lateral (LCHL) coracohumeral ligament (CHL), the long biceps tendon (LBT), the supraspinatus tendon (SSP) and the subscapularis tendon (SSC).

Is the rotator interval part of the rotator cuff?

The floor of the rotator cuff interval is the cartilage of the humeral head, and the roof of the rotator cuff interval is the rotator interval capsule, which links the subscapularis and supraspinatus tendons and is composed of two layers: the CHL on the bursal side and the fasciculus obliquus on the articular side [7].

Which ligament at the shoulder is located in the rotator interval?

coracohumeral ligament
The rotator interval contains the long head of the biceps tendon, coracohumeral ligament, superior glenohumeral ligament (SGHL), and the middle glenohumeral ligament (MGHL).

How long does an ultrasound take on a shoulder?

The examination itself usually lasts around 10-15 minutes and is pain free. At the end of the examination a brief explanation of the results may be offered. A formal ultrasound scan report with any recommendations will be sent to you which you can take to your regular healthcare professional.

Can you see shoulder impingement on ultrasound?

Ultrasonography (US) is a commonly performed examination for shoulder impingement, recommended by experts as the first-choice technique to evaluate various shoulder diseases. Shoulder impingement is the most common and well-recognized indication for dynamic US in the shoulder.

What makes up the rotator interval?

Rotator interval capsule is composed of coracohumeral ligament, superior glenohumeral ligament (SGHL), and capsular fibers, which all blend together along insertions medial and lateral to bicipital groove, maintaining biceps tendon within groove.
