SLAP and Labral Tears: Symptoms and Arthroscopic Treatment

Shoulder pain that sits deep inside the joint, clicks when you move, and drains the power out of a throw is one of the more frustrating problems I see. People can usually point to a sore knee or a stiff neck. A labral tear is harder to locate, and that is exactly what makes it confusing. This guide explains what the labrum is, what a SLAP tear means, how it shows up, and how I decide on treatment at Aster MIMS Hospital, Kannur.

What is the labrum, and what is a SLAP tear?

The shoulder is a ball-and-socket joint, but the socket is shallow, more like a saucer than a cup. That shallowness gives the shoulder its huge range of movement, and it is also why the shoulder relies so heavily on soft tissues for stability. The labrum is a rim of firm cartilage around the edge of the socket. It deepens the socket, helps hold the ball centred, and acts as an anchor point for ligaments and for the long head of the biceps tendon at the very top.

A SLAP tear is a tear of that upper part of the labrum. SLAP stands for Superior Labrum Anterior to Posterior, which simply means a tear running across the top of the rim, from front to back, often involving the spot where the biceps tendon attaches. Tears can also happen at the front or bottom of the labrum, where they are more often linked to shoulder dislocations and instability.

How does a SLAP tear happen?

SLAP and labral tears tend to arrive in one of two ways. The first is a single injury: a fall onto an outstretched hand, a sudden yank on the arm, or a heavy collision. The second, and the one I see often in sportspeople, is repetitive overhead loading. Years of bowling, throwing, serving, or overhead lifting can gradually wear and lever the upper labrum until it gives way. With age, the labrum also softens and frays naturally, which is why scans in older shoulders frequently show labral changes that were never the cause of any pain.

Symptoms: what a labral tear actually feels like

There is no single giveaway symptom, but a cluster of features should raise suspicion. Run through this checklist and note how many sound like your shoulder.

None of these is unique to a labral tear. They overlap heavily with rotator cuff problems and with shoulder instability, which is why a scan alone never tells the whole story. If this pattern sounds familiar, it is worth getting properly assessed rather than self-diagnosing from a search result.

How is it diagnosed?

Diagnosis is a layered process. It starts with your history, when the trouble began, what aggravates it, and what your shoulder has to do for work or sport. Next is a clinical examination using specific tests that stress the labrum and biceps anchor to reproduce the pain or clicking. Imaging then adds detail. A plain MRI is useful, and an MR arthrogram, where contrast dye is injected into the joint first, shows the labrum more clearly. Even with a good scan, the most reliable confirmation often comes during shoulder arthroscopy, when the labrum and biceps attachment can be seen and gently probed directly through a keyhole camera.

Treatment: it depends on your age and your activity

This is the part that gets oversimplified. There is no single right answer for a labral tear, because the right answer changes with who you are and what you need the shoulder to do. Broadly, treatment falls into three paths, and choosing well between them matters more than the technical detail of any one operation.

Repair, debridement, or non-surgical care?

Here is how the three main paths line up. These are general patterns, not rules, and your own plan is decided after a proper assessment.

The thread running through all of this is that a younger thrower and an older recreational player can have a similar-looking tear on the scan and still need quite different treatment. Age, the quality of the tissue, and how much the shoulder is asked to do all push the decision in different directions. That is why I spend time on the assessment rather than rushing to label the operation.

What recovery looks like

For a debridement or clean-up, recovery is relatively quick, with early movement and a staged return to activity. For a repair, the shoulder is rested in a sling for a few weeks to let the labrum heal back onto the bone, with gentle finger and elbow movement allowed early. Physiotherapy then progresses in stages over months, restoring movement first, then strength, then sport-specific loading before any return to throwing or bowling. Patience pays off here. Rushing a repair back into overhead sport is the surest way to undo it.

If you have been told you have a labral or SLAP tear and you are unsure whether surgery is really the answer, a careful second opinion can be reassuring either way. And if you would like to be assessed in person, you can book a consultation at my clinic at Aster MIMS Kannur.
