“…1a,b). -In the rotator interval: measured by the widest portion of the capsule and synovial at the center part of the rotator interval (defined as the middle distance between the superior aspect of the subscapularis tendon and the anterior aspect of the supraspinatus tendon) perpendicular to the adjacent humeral head cortex, according to Emig, Vahlensieck and Tetro [4,[13][14][15], on a sagittal T1-weighted spin-echo Gdchelate-enhanced sequence (Fig. 2a,b).…”

The magnetic resonance imaging (MRI) findings in idiopathic adhesive capsulitis (AC) were compared with those of contralateral healthy shoulders and the reliability of measures assessed. Twenty-six consecutive patients (26 AC and 14 healthy shoulders) were prospectively assessed. The main measurements were thickness of the joint capsule and synovial membrane in the axillary recess and rotator interval in T1-weighted spin-echo sequence enhanced with intravenous (IV) gadolinium chelate (Gd-chelate). Reliability was studied by use of the intraclass correlation coefficient (ICC). The mean thickness of the axillary recess on the coronal plane was 9.0+/-2.2 mm in AC shoulders and 0.4+/-0.7 mm in healthy shoulders. The mean thickness of the rotator interval on the sagittal plane was 8.4+/-2.8 in AC shoulders and 0.6+/-0.8 mm in healthy shoulders. Interobserver reliability was good for the axillary recess, with ICC values of 0.84 for the coronal plane, and good for the rotator interval, with ICC values of 0.80 for the sagittal plane. MRI with IV Gd-chelate injection can show, with acceptable reliability, signal and thickness abnormalities of the shoulder joint capsule and synovial membrane in AC.

“…This falsely increased the base dimension where, theoretically, this dimension should be the least variable with any motion. However, Tetro et al 19 noted that the coracohumeral ligament was lax with the arm in internal rotation and adduction and that the coracohumeral ligament was taut in external rotation. It is important to note that other authors have found a change in the RI with inferior traction.…”

“…11,14 Numerous recent studies have supported arthroscopic release for effectively treating refractory adhesive capsulitis through the controlled release of the capsular restraints. [4][5][6]15 Glenohumeral motion loss assessed in cadaveric cutting studies has clarified that the regional capsule must be released. 16,17 Loss of external rotation mandated the release of the MGHL, rotator interval, coracohumeral ligament extra-articularly, or intra-articular portion of the subscapularis.…”

“…The rotator interval tissue has been critically associated with the development of a frozen shoulder. 15,24 Because the pathological condition of the rotator interval tissue plays a primary role in adhesive capsulitis, release of the rotator interval may be justified. Harryman et al demonstrated an increase in the range of flexion, extension, and external rotation by sectioning the rotator interval capsule.…”

Purpose: To present the clinical results of arthroscopic extended rotator interval release with a stretching program for treating refractory adhesive capsulitis. Study design: Case series; level of evidence, 4. Methods: Arthroscopy-assisted extended rotator interval tissue release including anterior capsular was performed in 26 patients with refractory adhesive capsulitis. All rotator interval tissues, except the medial sling of the biceps, were excised and the excursion of the subscapularis tendon was restored and freely mobilized. The preoperative mean passive forward flexion was 101 , whereas external rotation at the side was 10. Patients were followed for a minimum of 2 years and their visual analog scale for pain, muscle power, range of motion, Constant score, modified American Shoulder and Elbow Surgeons Shoulder Evaluation Form score, and modified University of California at Los Angeles score were recorded. Results: Visual pain scale and the aforementioned clinical scores improved postoperatively. The patients exhibited a significant postoperative difference in forward flexion, external rotation, and internal rotation. Postoperative mean passive forward flexion was 172 , whereas external rotation at the side was 58. There was no difference in the muscle power postoperatively including abduction, internal rotation, and external rotation. Conclusions: Our study revealed satisfactory subjective and objective clinical results after a 2-year follow-up. Arthroscopy-assisted extended rotator interval release with a stretching program could be an alternative treatment for refractory adhesive capsulitis.
