A SLAP tear is a specific type of shoulder labrum injury. The term SLAP stands for superior labrum anterior to posterior. In simple language, it means a tear in the top part of the ring of tissue around the shoulder socket, often near the attachment of the biceps tendon.
In my practice, I often see patients who describe a deep shoulder pain that is difficult to point to with one finger. Some say the shoulder clicks, catches, or feels weak when lifting the arm overhead. Others notice the problem after a fall, a sudden pull, gym training, cricket, badminton, swimming, or repeated overhead work. For Bangladeshi patients, especially those living in Dhaka and balancing work, traffic, family duties, and limited time for rehabilitation, it is important to understand that not every shoulder pain is a simple muscle strain.
What Is a SLAP Tear?
The shoulder is a ball-and-socket joint. The socket is relatively shallow, so the body uses soft tissue for extra stability. One of these structures is the labrum, a ring of cartilage-like tissue around the socket. The labrum helps deepen the socket and supports shoulder stability.
In a SLAP tear, the upper part of the labrum is injured. This is also where the long head of the biceps tendon attaches. Because of that connection, patients may feel pain not only during shoulder movement but also with lifting, pulling, throwing, pushing, or carrying.
I usually explain to my patients that a SLAP tear is not the same as every other labral injury. A Bankart tear is more related to the front lower part of the labrum and shoulder instability after dislocation. A SLAP tear involves the top of the labrum and may present more with deep pain, clicking, and difficulty with overhead use.
How a SLAP Tear Happens
Sudden injury
A SLAP tear can happen after:
- a fall on an outstretched hand
- a road traffic accident
- sudden forceful pulling of the arm
- lifting a heavy object awkwardly
- shoulder dislocation
In Dhaka, I also see shoulder injuries after slipping on stairs, motorcycle incidents, manual work, and sudden jerking injuries during transport or crowded daily activity.
Repetitive overhead use
Some patients do not recall one clear accident. Instead, the tear may develop gradually from repeated overhead stress. This can happen in:
- cricket players
- badminton players
- swimmers
- gym users doing overhead pressing or pulling
- painters, electricians, and workers with repeated overhead tasks
One important point I want Bangladeshi patients to understand is that shoulder pain from repeated activity may start mildly and then become persistent. If the shoulder keeps clicking, weakens, or stops tolerating overhead use, it deserves proper assessment.
Common Symptoms of a SLAP Tear
The symptoms are not always dramatic. In fact, SLAP tears can be confusing because they may look like other shoulder problems.
Symptoms I commonly hear from patients
- deep shoulder pain
- pain when lifting the arm overhead
- clicking, popping, or catching
- a feeling of weakness
- pain with throwing or forceful pulling
- discomfort when carrying weight
- reduced sports performance
- a “dead arm” feeling during overhead activity
Some patients also have night discomfort or pain when turning in bed onto the affected side. Others mainly complain that the shoulder no longer feels reliable for work, sports, or exercise.
When a SLAP Tear May Be Mistaken for Something Else
When I evaluate patients with this problem, I do not assume every MRI report or every clicking shoulder is a SLAP tear that needs surgery. Shoulder pain can also come from:
- rotator cuff problems
- biceps tendon irritation
- frozen shoulder
- AC joint problems
- scapular dyskinesia
- neck-related pain
- generalized shoulder instability
This is why the history and physical examination matter so much. Imaging alone does not tell the full story. Some labral changes may be present on scans, especially with age, without being the main cause of symptoms.
How I Evaluate a Suspected SLAP Tear
Medical history
I first want to understand:
- whether the pain started after trauma or overuse
- whether there is clicking, catching, or instability
- which activities make it worse
- whether there is weakness, numbness, or neck pain
- whether the patient plays sports or performs overhead work
For Bangladeshi patients, the daily context matters. A college student, office worker, homemaker, manual laborer, and recreational athlete do not stress the shoulder in the same way. Treatment should match real-life demands.
Physical examination
During examination, I look at:
- range of motion
- strength
- shoulder stability
- pain location
- scapular control
- biceps-related signs
- possible associated rotator cuff injury
No single test is perfect for diagnosing a SLAP tear. Usually, I combine the patient history, examination findings, and imaging when needed.
