7 Consequences: What Happens if Shoulder Instability Is Left Untreated

May 24, 2024

Shoulder instability is a condition that can significantly impact your daily life. It occurs when the structures surrounding the shoulder joint do not work as they should, leading to frequent dislocations and a persistent feeling of the shoulder being loose. 

Many people may underestimate the importance of addressing this issue and understanding what happens if shoulder instability is left untreated, thinking it will be resolved independently. However, the consequences of neglecting shoulder instability can be severe.

If shoulder instability is not addressed, the condition can eventually worsen, leading to more frequent dislocations, increased pain, and potential long-term damage to the shoulder joint. 

In this article, let's explore the seven significant consequences of untreated shoulder instability, providing valuable insights into why early intervention is crucial.

Understanding what happens if shoulder instability is left untreated can help you make informed decisions about your health. Continue reading to learn about the significant impacts and how they can affect your overall quality of life. 

What Happens if Shoulder Instability Is Left Untreated

When shoulder instability is left untreated, several serious consequences can arise. Understanding these outcomes emphasizes the importance of seeking timely medical intervention.

  1. Increased risk of dislocations

The shoulder joint remains unstable without proper treatment, leading to frequent dislocations. Each dislocation causes further damage to the ligaments, tendons, and muscles, exacerbating the instability.

  1. Chronic pain

Persistent instability often results in chronic pain. This pain can limit daily activities and reduce the overall quality of life. This makes it undeniably challenging to perform even simple tasks like lifting objects or reaching overhead.

  1. Joint damage

Repeated dislocations can lead to significant damage to the shoulder joint. Over time, this damage can cause arthritis, characterized by joint pain, swelling, and reduced mobility.

  1. Muscle weakness

The muscles surrounding the shoulder can weaken due to repeated dislocations and lack of stability. This weakness further contributes to instability, creating a complex cycle that cannot be broken without intervention.

  1. Decreased range of motion

Untreated shoulder instability often results in a decreased range of motion. Activities that require shoulder movement become increasingly tricky, limiting participation in sports, work, and daily activities.

  1. Nerve damage

Frequent dislocations can damage the nerves around the shoulder joint. Nerve damage can cause numbness, tingling, and loss of sensation in the shoulder and arm, further complicating the condition.

  1. Impact on mental health

Chronic pain, limited mobility, and ongoing medical issues can significantly impact mental health. Anxiety, depression, and a sense of helplessness are common among those dealing with untreated shoulder instability.

Addressing shoulder instability early is crucial to prevent these severe consequences. With timely intervention, knowing what happens if shoulder stability is left untreated can restore stability, reduce pain, and improve shoulder joint function.

What Does an Unstable Shoulder Feel Like?

An unstable shoulder can manifest in several ways, often causing discomfort and difficulty with everyday activities. Here are the common sensations and symptoms associated with an unstable shoulder:

  • Frequent dislocations or subluxations

An unstable shoulder may frequently dislocate or partially dislocate (subluxation). This sensation can feel like the shoulder is slipping out of place and can happen during simple movements or activities. These episodes can be sudden and unpredictable, making it difficult to trust the stability of your shoulder during any activity.

  • Pain and discomfort

Pain is a common symptom of shoulder instability. It can cause sharp pain during a dislocation or constant dullness due to ongoing instability and stress on the shoulder joint. Pain may also increase with certain movements, such as lifting or reaching, and can sometimes extend down the arm.

  • Weakness in the shoulder

Many people with shoulder instability experience weakness in the shoulder and arm. This weakness can make lifting objects challenging or performing tasks requiring strength. The lack of stability can cause muscles to compensate inappropriately, leading to fatigue and further weakness.

  • Feeling of looseness or "giving way"

A feeling of looseness or that the shoulder might "give way" during activities is typical. This sensation can create anxiety about using the shoulder for certain movements. This can be particularly concerning during activities that involve overhead motions or bearing weight on the shoulder.

  • Clicking or popping sounds

Some individuals may notice clicking or popping sounds when moving their shoulders. These sounds can be a sign of instability and underlying joint issues. The noises may be accompanied by a sensation of catching or locking, adding to the discomfort and unpredictability of shoulder movement.

  • Limited range of motion

Shoulder instability can result in a limited range of motion and difficulty performing tasks requiring full shoulder mobility. This restriction can impact daily activities, including dressing, reaching for items on high shelves, and participating in sports and exercises.

  • Swelling and inflammation

Repeated dislocations or subluxations can cause swelling and inflammation in the shoulder joint. This can lead to stiffness and increased pain, further limiting the shoulder's functionality and comfort.

Understanding these symptoms can help identify shoulder instability early. Recognizing what happens if shoulder instability is left untreated is vital for seeking timely medical care and preventing further complications. Shoulder instability can be managed better when diagnosed early and treated promptly, improving the quality of life for those affected.

Is Shoulder Instability Permanent?

Shoulder instability can be temporary or permanent, depending on several factors, such as the cause, severity, and treatment.

  • Temporary shoulder instability

In some cases, shoulder instability is temporary and can be resolved with proper treatment. Physical therapy and rehabilitation exercises can strengthen the muscles around the shoulder, improving stability and function.

  • Permanent shoulder instability

In other instances, shoulder instability may become a long-term issue. This can occur if the condition is severe, significant joint damage has occurred, or it is not treated promptly. Surgical intervention may be recommended to restore stability in such cases.

  • Factors affecting permanence

The likelihood of shoulder instability being permanent depends on factors like age, activity level, and the number of previous dislocations. Younger individuals or those involved in high-risk sports may have a higher chance of recurring instability.

Understanding the potential permanence of shoulder instability highlights the importance of early intervention. Recognizing what happens if shoulder instability is left untreated can motivate individuals to seek the necessary care to avoid long-term issues.

What Is the Success Rate of Shoulder Instability Surgery?

Shoulder instability surgery aims to restore stability to the shoulder joint, and its success rate is generally high.

  • Clinical outcomes

Over 80% of patients report good or excellent outcomes after shoulder instability surgery. This indicates a significant improvement in stability, function, and pain reduction. Clinical scores used to measure outcomes often show marked improvement post-surgery, reflecting the procedure's effectiveness.

  • Recurrence rates

Despite the high success rate, the recurrence rate is still 5.1% to over 20%. Factors such as the patient's age, activity level, and the number of previous dislocations can influence this. Younger patients and those engaged in high-impact sports may have a higher likelihood of recurrence, necessitating careful post-surgical management and possible lifestyle adjustments.

  • Patient satisfaction

Patient satisfaction with shoulder instability surgery is typically high. Over 80% of patients return to their previous activity levels, indicating that the surgery effectively restores shoulder function. High patient satisfaction rates are often attributed to significant pain reductions and improvements in the shoulder's range of motion and strength.

  • Long-term benefits

The long-term benefits of shoulder instability surgery include sustained stability and improved shoulder joint function. While some patients may experience degenerative changes over time, these do not necessarily impact the overall functional outcomes. Regular follow-up and physical therapy can help maintain these benefits and prevent further complications.

  • Rehabilitation and recovery

The success of shoulder instability surgery also depends on the rehabilitation process. A well-structured physical therapy program is crucial for strengthening the shoulder muscles and improving joint stability. Adherence to post-operative care instructions significantly enhances recovery outcomes and minimizes re-injury risk.

Understanding these success rates and associated factors helps set realistic expectations for those considering surgery. Knowing what happens if shoulder instability is left untreated can encourage patients to explore surgical options if non-surgical treatments are insufficient. 

Final Thoughts

Shoulder instability is a serious condition that can lead to numerous complications if left untreated. Chronic pain, frequent dislocations, joint damage, and even mental health issues are just among the many potential consequences.
