What is the effect of a complete Type II SLAP lesion?

A complete Type II SLAP lesion involves the complete detachment of the superior labrum from the glenoid, along with the associated biceps tendon. In this injury, the labrum is not merely frayed or partially torn; it is fully detached, which can lead to instability in the shoulder joint. This detachment can significantly impair the function of the shoulder, causing pain, limited range of motion, and potentially affecting the biceps muscle, as the tendon is attached to the labrum.

Understanding this type of injury is vital for correctly diagnosing and choosing the appropriate treatment approach, whether conservative management or surgical intervention. The full detachment distinguishes it from partial tears or lesions that may not involve the labrum’s complete separation from the bone, leading to different clinical implications and management strategies for each type of shoulder injury.
