Anatomic schema showing a posterior view of a right shoulder. The probe entering from the right from an anterolateral portal is elevating a labral tear to evacuate a paralabral ganglion cyst (shown in yellow) that is compressing the SSN at the spinoglenoid notch (shown in orange). Typically, an egress of cloudy fluid is encountered with disturbance of the cyst. When one is performing subacromial SSN release, in rare cases, the TSL may be ossified (arrow). In these instances, it is described as a type VI TSL and usually needs to be taken down with a quarter-inch osteotome.
