SLAP Tear in the Shoulder
A SLAP tear is a common shoulder injury for athletes and weekend warriors, particularly those engaged in overhead activities, like basketball, tennis, or house painting. This specific type of labrum tear in your shoulder affects the ring of cartilage that stabilizes your shoulder joint and keeps it moving smoothly. Whether caused by sports, aging, or overuse, a labrum SLAP tear can lead to chronic pain and long-term instability if left untreated.
At Hoag Orthopedic Institute, our world-class, board-certified orthopedic shoulder specialists use advanced imaging, expert evaluation, and personalized treatment plans to diagnose and treat SLAP tears in the shoulder accurately. With surgical and non-surgical shoulder treatment options, we help patients recover strength, stability, and confidence so they can return to the activities they love.
What is a SLAP Tear?
A SLAP tear is a specific type of labrum tear in your shoulder that affects the upper or superior part of the labrum — the ring of cartilage that surrounds, cushions, and stabilizes the shoulder socket. SLAP stands for Superior Labrum Anterior to Posterior, describing the location and direction of the tear. A SLAP tear or SLAP lesion occurs where the biceps tendon attaches to the labrum, making it vulnerable during overhead motions or sudden pulling forces.
A shoulder SLAP tear can range from mild fraying to complete detachment of the labrum. Because the labrum plays a key role in joint stability, even a partial tear can lead to pain, catching, or locking sensations, and reduced shoulder function.
Common SLAP Tear Symptoms
A SLAP tear or SLAP lesion shoulder injury can cause various symptoms, depending on the severity and type of tear. Some people experience only mild discomfort at first, while others feel sharp pain or instability immediately.
Common signs of a SLAP tear in your labrum include:
- Deep, aching pain inside the shoulder joint
- Pain that worsens with overhead movement or lifting
- Catching, popping, or grinding sensations during movement
- Loss of shoulder strength or range of motion
- Instability or weakness in the shoulder
- Discomfort during everyday activities, such as reaching or throwing
SLAP tear symptoms may overlap with other shoulder conditions, so an accurate diagnosis is key to effective treatment. If you’re experiencing persistent shoulder pain, stiffness, or clicking, consult a Hoag Orthopedic Institute specialist.
What causes SLAP tears?
SLAP tears can result from acute injury or repetitive stress. Sudden traumatic injuries are common causes, such as falling onto an outstretched arm, trying to catch yourself during a fall, or a direct blow to the shoulder. More commonly, SLAP tears result from repetitive overhead motions in sports and other activities. Athletes involved in baseball, tennis, swimming, or weightlifting, where the shoulder is repeatedly loaded and rotated, are at increased risk. Over time, this motion can wear down the labrum, leading to a SLAP tear shoulder injury.
Degeneration can also play a role in developing SLAP tears. As we age, the labrum naturally becomes more brittle, increasing the risk of tearing even with minor stress or movement. In some cases, improper lifting technique, heavy pulling motions, or a previous shoulder injury may also cause a SLAP tear in your labrum to develop or worsen.
Types of SLAP Tears
SLAP tears are classified by the severity and pattern of damage to the superior labrum and surrounding structures. The four most common SLAP tear types are:
- Type I: The labrum shows fraying but remains attached. Typically associated with aging, this type seldom requires surgery.
- Type II: In the most common type of SLAP lesion shoulder injury, the superior labrum and the biceps tendon anchor detach from the glenoid (shoulder socket). This often requires surgical repair.
- Type III: A “bucket handle” or crescent-shaped tear of the labrum that leaves the biceps tendon attached and intact.
- Type IV: Similar to Type III, but the labrum tear extends into the biceps tendon itself. This injury may require both labrum and biceps tendon repair or trimming.
Less common variations and more complex SLAP tear injuries may involve combined patterns or coexist with rotator cuff tears and other shoulder instability issues. A qualified orthopedic specialist can evaluate the SLAP tear type and recommend a treatment plan tailored specifically for you.
Treatment Options for SLAP Tear Injuries
SLAP tear treatment depends on the type and severity of the injury, as well as your age, activity level, and overall health. Many minor or moderate labrum SLAP tear shoulder injuries respond well to non-surgical care, such as:
- Rest and activity modification
- Anti-inflammatory medications
- Physical therapy that strengthens the shoulder and restores mobility
However, if conservative treatment does not relieve symptoms or if the SLAP tear is more severe, your sports medicine specialist may recommend arthroscopic shoulder surgery to remove or repair the damaged tissue.
Common surgical procedures include debridement (removing loose or frayed cartilage), SLAP repair (reattaching the torn labrum, or biceps tendonesis, which involves moving the biceps tendon attachment to reduce stress on the labrum.
At Hoag Orthopedic Institute, our experienced surgeons use minimally invasive techniques whenever possible to reduce pain and support a faster recovery. Only for the most severe SLAP tears involving significant pain, joint instability, and loss of function would a shoulder replacement be considered.
