Superior labral (SLAP) tears and disorders of the long head of biceps — assessment and treatment.
What you're feeling
You may feel pain deep in the front of your shoulder. This area is where the long head of the biceps tendon attaches. Your pain might feel like it comes from a tear in the top part of your shoulder socket, known as a SLAP lesion. Sometimes this pain mimics other issues like impingement or rotator cuff problems. You might also notice pain if you have calcific tendinitis, which is calcium buildup in the tendon.
Daily tasks can become difficult when you try to move your arm. You may struggle to reach behind your back to fasten a bra or tuck in a shirt. Lifting objects overhead or carrying heavy bags often makes the pain worse. The discomfort can flare up after activity or when you wake up in the morning. Sleeping on the side of the injured shoulder is often very painful and disrupts your rest.
Your surgeon will look at your specific symptoms before deciding on a treatment plan. They will not rely on physical exam tests alone to make this decision. If you are under 30 years old, your surgeon might discuss biceps tenodesis as an option. This procedure can help active patients return to their normal activities faster than other repairs. If you are over 40, or if you smoke or have obesity, your surgeon will consider these factors carefully. The goal is to find the right path to reduce your pain and restore your function.
What's actually happening
Your shoulder has a ring of tissue called the labrum that acts like a gasket around the joint. Sometimes this ring gets torn, especially where the biceps tendon attaches. This injury is called a SLAP lesion. It can feel like impingement, rotator cuff damage, or shoulder instability, making it hard to pinpoint the exact problem. In people older than 50 years, wear-and-tear changes in this area are common even without other major injuries.
When this tear happens, your shoulder muscles change how they work. The biceps muscle and others may start later than usual, while the serratus anterior muscle starts earlier. Think of this as your body trying to protect the joint from moving too loosely. This shift can increase stress on the joint and pull harder on the biceps tendon. While small tears might not change how the bones move, they do increase tension and load on the front of the shoulder. This extra strain is often what causes your pain and dysfunction.
Your surgeon may discuss different ways to fix this. For active patients under 30 years old, cutting and reattaching the biceps tendon (biceps tenodesis) is often a reliable option. It can be done through a small cut in the chest or with a camera. This approach often leads to better results and faster return to activity compared to repairing the labrum directly. For patients aged 50 years or younger, this method can also save money. Both repair and tenodesis are safe choices, but your surgeon will decide which path is best for your specific situation.
What we can do about it
Your journey usually begins with self-management and physiotherapy. Your surgeon will likely recommend a specific regimen before suggesting any operation. This approach aims to reduce pain and improve your shoulder movement without surgery. For middle-aged patients with symptomatic SLAP lesions, non-operative treatment provides satisfactory clinical outcomes. You should consider this path before recommending operative treatment. A clinical prediction model can help predict the failure of non-operative management with moderate accuracy. However, a decision to operate should not be made on the basis of clinical assessment tests alone.
If pain persists, your surgeon may discuss medical management options. These include pain medication and anti-inflammatories to help you feel better. Injections such as cortisone, hyaluronic acid, or PRP may also be considered to manage symptoms. While the evidence highlights these as potential tools, the decision to use them depends on your specific symptoms and activity level. Treatment decisions are driven primarily by the presence of pain, your overhead activity level, and how well you have responded to prior non-operative management.
Surgery is considered when conservative care has reached its limit or if you remain in pain. Your surgeon will discuss whether biceps tenodesis or SLAP repair is the right choice for you. Primary biceps tenodesis offers improved functional results in active patients under 30 compared to SLAP repair. It is also a safe, effective, and technically straightforward alternative for type II and IV SLAP tears. For patients over 50, the presence of superior labral abnormalities is common, and treatment is tailored individually. Ultimately, the decision is made together with you based on your goals and the specific nature of your injury.
When to see someone
See your GP if you have persistent shoulder pain that does not improve with rest. Ask for a specialist review if you feel weakness, instability, or if your shoulder locks or gives way. Seek help if symptoms interfere with sleep or work, or if you notice a sudden worsening. Be aware that SLAP lesions can mimic other issues like impingement or rotator cuff problems. A decision to operate should not be based on clinical tests alone. If you are over 40, have obesity, smoke, or have biceps tendinitis, you may face a higher risk of needing revision surgery.
