WHAT IS A SLAP TEAR?
Superior Labrum Anterior and Posterior (SLAP) lesions describe a spectrum of injuries to the superior portion of the labrum, where one of the two biceps tendons partially attaches. The labrum is a bumper with a rubber-like consistency that surrounds the socket (i.e. glenoid) of the shoulder. It provides stability to the shoulder and is an important attachment site for the biceps tendon and other shoulder ligaments. When injured, patients may have no symptoms or possibly develop symptoms of:
- Pain
- Instability
- Mechanical symptoms (e.g. “popping” or “catching”)
- A combination of the above
SLAP lesions occur most commonly in throwing athletes, swimmers, volleyball players. They can also occur as a result of trauma, such as a traction injury or a fall onto an outstretched hand. However, as we age, our labral tissue can show signs of wear and tear, which can appear as a SLAP lesion on imaging studies. Importantly though, these “degenerative SLAP lesions” are rarely a source of pain and are usually an incidental finding.
If you are experiencing shoulder pain or would like to learn more don’t hesitate to reach out.
