2. Fig 1
Intra-articular view of a left shoulder. Standard posterior viewing portal and 30° arthroscope used. The first image shows needle localization of the anterosuperior portal in the rotator interval immediately anterior to the leading edge of the supraspinatus. The second image shows that a correct location is confirmed by easy passage of the needle into the bicipital groove to pass anterior to the LHB tendon. (HH, humeral head; LHB, long head of biceps; RI, rotator interval; SS, supraspinatus.)

3. Fig 2
External view of a left shoulder. This shows the correct location of the anterosuperior portal in front of the acromioclavicular joint. The transverse skin marking indicates the lower border of the pectoralis major tendon, and the vertical skin marking shows a typical cosmetic incision for an open subpectoral tenodesis. The arthroscope is bought out through the skin in a 5-mm incision made in the second line. As can be seen in the image, this allows the surgeon to engage the shaver in the mouth of the arthroscope sheath to carefully guide it into the bicipital groove in a retrograde fashion.

4. Fig 3
Insertion of a switching stick into the bicipital groove of a left shoulder. The key point to note is insertion of the switching stick anterior to the tendon to facilitate subsequent insertion of the arthroscope anterior to the biceps muscle belly. (LHB, long head biceps tendon; SS, supraspinatus.)

5. Fig 4
Biceps tenoscopy of a left shoulder viewing with a 30° arthroscope inserted through the anterosuperior portal with retrograde instrumentation. The first image shows how the view of the long head of biceps (LHB) tendon can often be initially obscured by loose connective tissue, synovitis or a degenerative lesion. The second image shows the high-quality view that can be obtained after excision of loose connective tissue, a tendinopathic lesion, and a small groove osteophyte.

6. Fig 5
External view of a left shoulder. A pink needle has been placed approximately 1 cm above the lower border of the pectoralis major (indicated by a blue line, indicating the location of the musculotendinous junction). A cannula has been placed in the subpectoral incision to facilitate quick insertion and removal of retrograde instrumentation, although this is not essential. Viewing the needle at biceps tenoscopy gives additional feedback that the most distal zone of the long head of biceps (Denard zone C) is fully visualized.
