Advantages and Disadvantages of Arthroscopic and Endoscopic Technique for Subcoracoid Synovial Chondromatosis of Shoulder Through Medial Transpectoral Portal

Advantages

The technique is safe when used under direct visualization.

The M portal is the same portal used for procedures such as the arthroscopic Latarjet procedure, so it can be used in other procedures as well.

The M portal should be in line with the glenoid surface. This is important when using screws to fix anterior glenoid neck fractures.

Disadvantages

A learning curve and outside-the-box anatomy knowledge are required.

Bleeding can occur at the base of the coracoid. The surgeon should avoid dissecting too far proximally. The limit is the conoid ligament to avoid damaging the suprascapular nerve.
