2. Fig 1
Coronal computed tomography scan of the SCJs with superimposed inferior and superior portal positions (yellow X) on either side of the anterior SC ligament (red diamonds). One should note the relatively small area of bony congruence at the inferior part of the joint, making it the most suitable position to establish the initial portal.

3. Fig 2
Axial computed tomography scan of the SCJ showing the 30° angulation of the sternal articular surface in relation to the vertical axis. This indicates the angle at which the arthroscopic camera and instruments need to be inserted to run parallel to the medial side of the joint.

4. Fig 3
(A) An 18-gauge spinal needle is inserted at the inferior part of the SCJ at an angle of 30° to the vertical plane. Normal saline solution is then infiltrated into the joint space with minimal resistance to confirm correct placement. (B) The arthroscopic cannula with a blunt trocar is inserted into the inferior joint space at an angle of 30°. The cannula often passes more than 20 mm before it penetrates the anterior capsule with a definite “pop.”

5. Fig 4
Arthroscopic image of right SCJ. The mini-probe is on the superior edge of the torn disk and the relatively well-preserved sternal articular cartilage is on the right, with the more degenerated clavicular cartilage on the left.

6. Fig 5
Magnetic resonance imaging scans (T2 short tau inversion recovery coronal views) of both SCJs showing a superior tear of the disk on the left side compared with the normal right side. The truncated appearance with edema outlining the disk is characteristic of a disk tear.

7. Fig 6
Arthroscopic image of left SCJ. (A) Micro-punch resecting torn disk. (B) The disk has been resected, and the probe touching the posterior capsule can be seen. One should note the relative preservation of the sternal articular cartilage on the left side.
