Shoulder pain that lingers, catches, or comes with weakness often traces back to one of two structures: the rotator cuff or the labrum. Both are common sources of shoulder trouble, and both are very treatable once you know what you are dealing with. Here is a plain-language guide to rotator cuff tears and shoulder labrum tears, how they are treated, and when it is worth seeing a specialist.
The shoulder is a remarkably mobile joint, which is part of why it is vulnerable to injury. The rotator cuff is a group of muscles and tendons that holds the upper arm in its socket and powers much of the shoulder's movement. The labrum is a rim of cartilage that deepens the socket and helps keep the joint stable. When either one is injured, the shoulder can become painful, weak, or unstable.
A rotator cuff tear happens when one of those tendons is damaged, either suddenly from a fall or a lifting injury, or gradually from years of wear. Common signs include pain on the outside of the shoulder, weakness when lifting or reaching overhead, and pain that is worse at night or when lying on that side. Not every tear needs surgery, and many people improve with the right treatment.
A torn shoulder labrum can be harder to pin down. Because the labrum helps hold the joint together, a tear often shows up as a deep ache, a catching or clicking sensation, or a feeling that the shoulder is loose or about to slip out of place. Labral tears can follow a specific injury, such as a dislocation or a hard fall on an outstretched arm, or they can build up over time from repetitive overhead activity in sports or at work.
Diagnosis usually starts with a conversation about how the pain began and a hands-on examination of the shoulder's strength and movement. Imaging, often an MRI, can help confirm which structure is involved and how significant the injury is. Getting the diagnosis right matters, because rotator cuff and labral problems are treated differently.
Many shoulder injuries improve without surgery. Resting from the activities that aggravate it, a course of physical therapy to rebuild strength and movement, and in some cases an injection to calm inflammation are common first steps. For a lot of people, this is enough.
Surgery tends to enter the conversation when the shoulder is not improving with conservative care, when a tear is large or complete, or when instability keeps interfering with daily life or sport. Rotator cuff repair and labral repair are often done arthroscopically, through small incisions, by an orthopaedic shoulder specialist.
Recovery from a shoulder injury takes patience, and the timeline depends on the injury and whether surgery was involved. Physical therapy is almost always central to a good result, and going back too soon is a common reason problems return. Your care team can give you a realistic picture for your specific situation.
It is worth having your shoulder evaluated if the pain persists beyond a couple of weeks, if you notice weakness or trouble lifting, if the shoulder feels unstable, or if the pain regularly disrupts your sleep. For injuries tied to sport or activity, our sports medicine physicians can help you get back to what you enjoy, safely.
