A SLAP ( Superior Labrum tear from Anterior to Posterior) lesion is an injury to the labrum of the shoulder. The labrum is a sleeve of connective tissue that surrounds the joint and is vital for stability of your shoulder.
Your rotator cuff is made up of 4 muscles that lay close around your shoulder joint. They are responsible for up to 80% of your shoulder’s dynamic stability. A massive rotator cuff tear is when you have significantly torn some or all of these muscles.
