A shoulder that dislocates during a sports injury can sometimes become prone to doing it again. This does not necessarily mean the original injury was severe or that surgery will automatically be needed.
Often, the key question is what happened to the structures that normally keep the shoulder joint stable.
Key takeaways
- A first shoulder dislocation can stretch or damage tissues that help keep the joint in position.
- Repeated dislocations may indicate ongoing shoulder instability rather than simply another isolated injury.
- The risk of recurrence can be influenced by factors such as age, activity level, the direction of the injury and damage to surrounding structures.
- Assessment may involve a physical examination and, when appropriate, imaging to understand the underlying problem.
- Treatment depends on the individual’s injury, shoulder stability, activity requirements and previous dislocations.
Why can one dislocation make another more likely?
The shoulder is designed to have a wide range of movement, but that mobility comes with a trade-off: it relies heavily on soft tissues and surrounding muscles to maintain stability.
During a dislocation, structures such as the labrum, ligaments and joint capsule may be stretched or injured. The muscles around the shoulder can also be affected.
After the joint is put back into position, the shoulder may feel better, but the underlying tissues may still need time to recover. In some people, the injury can leave the joint more vulnerable to slipping out of position again, particularly during activities involving forceful or overhead movements.
This is why a recurrent shoulder dislocation is not always simply a case of “the shoulder being weak”.
Could the first injury have caused damage that is still there?
Yes. A sports-related dislocation can involve more than the joint temporarily moving out of place.
A doctor may consider whether there is damage involving,
- The labrum, a ring of tissue that contributes to shoulder stability
- The ligaments and joint capsule surrounding the shoulder
- The bones forming the shoulder joint
- The muscles and tendons that help control shoulder movement
The significance of these injuries varies between individuals. A person who continues to experience instability may therefore need a different assessment from someone who has had one uncomplicated dislocation and recovered well.
Why does the shoulder sometimes “give way” even without a major injury?
Not every episode of instability looks like a dramatic dislocation. Some people describe the shoulder as slipping, shifting or briefly feeling as though it is about to come out of place. Others may experience apprehension when putting the arm into certain positions.
This distinction matters. Repeated episodes can provide useful information about how stable the shoulder is during movement.
If instability keeps occurring during sport, exercise or everyday activities, continuing to push through the symptoms may not address the underlying problem. A clinical assessment can help determine whether the sensation is coming from recurrent instability or another shoulder condition.
Does recurrent instability always mean surgery?
No. Treatment is not decided simply by counting the number of dislocations.
Depending on the individual assessment, management may involve rehabilitation to improve shoulder strength, movement control and stability. Activity modification may also form part of the recovery process.
In other situations, particularly where there is structural damage or repeated instability, a doctor may discuss whether a surgical procedure should be considered.
The decision depends on factors such as,
- The nature and extent of the injury
- Whether the shoulder has dislocated repeatedly
- The person’s age and activity level
- Sporting requirements
- Findings from physical examination and imaging
- Previous treatment and rehabilitation
The aim is to match management to the actual cause of instability rather than assuming that every shoulder dislocation needs the same treatment.
What should an athlete do after a second dislocation?
A second episode deserves assessment, particularly if the shoulder has repeatedly slipped out of position or feels unstable during sport.
Trying to return to the same activity immediately may place additional stress on an already unstable shoulder. A spine doctor or a spine specialist can also assess the shoulder and determine whether further investigations are appropriate.
Frequently Asked Questions
Can a shoulder dislocate again after it has been put back in place?
Yes. Some people experience recurrent instability after an initial dislocation, particularly when structures that contribute to shoulder stability have been injured.
Can physiotherapy help with an unstable shoulder?
Rehabilitation may help improve muscle strength, movement control and shoulder stability in appropriate cases. The programme should be guided by the individual’s injury and stage of recovery.
Will I need an MRI after a shoulder dislocation?
Not necessarily. The need for imaging depends on the clinical assessment and what the doctor is trying to determine. Different imaging methods may be considered depending on the suspected injury.
Should I stop playing sports after a shoulder dislocation?
A return to sport should take into account the stability of the shoulder, recovery and the demands of the particular activity. Returning too quickly may not be appropriate for everyone.
When should recurrent shoulder instability be assessed?
If the shoulder repeatedly slips, dislocates, feels unstable or causes apprehension during movement, an orthopaedic assessment can help identify the possible cause and appropriate next steps.
Book a consultation and have your shoulder assessed
Repeated shoulder dislocation is worth investigating rather than treating each episode as an isolated accident. Understanding whether the problem involves the soft tissues, bone, muscle control or a combination of factors can help guide the next step.
If shoulder instability is affecting sport, exercise or daily activities, consider discussing it with Dr. MASH at MASH Spine & Orthopaedics. An assessment can help determine what may be contributing to the recurrent problem and whether further investigation or treatment is appropriate for your individual situation.
