Winging of Scapula: Causes, Symptoms, Nerve Damage & Exercises That May Help

Updated September 9, 2026

What is a winged scapula?

A winged scapula or Winging of Scapula occurs when the shoulder blade protrudes away from the rib cage instead of resting relatively flat against it. It can result from weakness, altered muscle control, nerve injury, trauma or other shoulder/scapular problems. The treatment depends on identifying the underlying cause.

Quick answer:

• Mild muscle-control problems may respond to rehabilitation.
• Nerve injuries can take considerably longer.
• Persistent or worsening winging deserves professional assessment.
• Exercises should be selected according to the cause.

Causes

1. Nerve damage: The most common cause of scapular winging is damage or dysfunction of the long thoracic nerve, which controls the muscles that stabilize the scapula. This nerve can be injured due to trauma, compression, or repetitive overuse, such as in sports or certain occupations.
2. Muscle weakness or imbalances: Weakness or imbalances in the muscles around the scapula, particularly the serratus anterior, can lead to scapular winging. This can occur due to muscle atrophy, nerve damage, or inadequate muscle activation.
3. Trauma or injury: Direct trauma to the scapula or surrounding structures can result in scapular winging. Fractures or dislocations of the shoulder or scapula can disrupt the normal alignment and function of the scapula.
4. Muscular disorders: Certain neuromuscular conditions, such as muscular dystrophy or myopathy, can affect the muscles responsible for scapular stabilization and contribute to scapular winging.

Symptoms

• Visible protrusion or abnormal movement of the scapula when moving the arm or pushing against resistance.
• Weakness or difficulty with overhead activities, pushing, or pulling.
• Shoulder or upper back pain.
• Limited range of motion in the shoulder.
• Fatigue or discomfort with prolonged shoulder use.

Winged Scapula vs Scapular Dyskinesis

Seeing your shoulder blade move abnormally does not automatically mean that you have a nerve injury. True scapular winging and scapular dyskinesis can look similar, but they are not necessarily the same problem. Identifying the underlying cause is important because treatment depends on what is affecting normal scapular movement.

True Scapular Winging

True winging occurs when the shoulder blade visibly protrudes away from the rib cage, often because one or more muscles that stabilize the scapula are not functioning normally.

The winging may become more noticeable when raising the arm or pushing against resistance.

Scapular Dyskinesis

Scapular dyskinesis refers to an altered or abnormal pattern of scapular movement. The shoulder blade may move differently during arm movements without necessarily representing a nerve injury.

It can be associated with muscle weakness, altered movement control, shoulder problems, posture or other factors.

What Can Cause Abnormal Scapular Movement?

1

Neurological Causes

Nerve injury can weaken muscles responsible for stabilizing the scapula. For example, long thoracic nerve dysfunction can affect the serratus anterior, while other nerve problems may affect different scapular stabilizing muscles.

2

Muscular Weakness

Weakness or poor activation of muscles such as the serratus anterior, trapezius or rhomboids can alter scapular control and contribute to abnormal movement.

3

Traumatic Causes

Shoulder or scapular trauma, including certain fractures, dislocations or injuries to surrounding tissues, can interfere with normal scapular movement.

4

Movement and Postural Factors

Changes in shoulder mechanics, muscle coordination and posture can influence how the scapula moves. These factors should not automatically be assumed to indicate a nerve injury.

Important:

A visibly prominent shoulder blade does not by itself identify the cause. A physiotherapist or other qualified healthcare professional can assess scapular movement, muscle strength, shoulder function and neurological signs to determine whether further investigation is needed.

Diagnosis of winging of scapula ?

The diagnosis of scapular winging typically involves a comprehensive evaluation by a healthcare professional such as an orthopedic specialist or a physical therapist.

The process may include the following steps:

Medical history:

The healthcare professional will ask about when the winging began, relevant medical conditions, previous injuries, and activities that may contribute to the problem.

Physical examination:

The healthcare provider will review the patient’s medical history, symptoms, and any previous injuries.

They may ask you to perform certain movements and resistances to evaluate the function of the scapular stabilizing muscles.

Muscle testing:

The strength and function of the muscles around the scapula will be assessed.

Weakness or imbalance in these muscles can contribute to scapular winging.

Nerve assessment:

If nerve damage is suspected as an underlying cause of scapular winging, the healthcare professional may perform additional tests to evaluate nerve function.

The healthcare professional may perform additional tests to evaluate the function of the nerves in the shoulder region.

This may include nerve conduction studies or electromyography (EMG) to assess the electrical activity of the muscles and nerves.

Imaging studies:

In some cases, imaging studies may be advised to rule out structural abnormalities.

X-rays, magnetic resonance imaging (MRI), or computed tomography (CT) scans may be used to assess bony structures, soft tissues and the overall alignment of the shoulder joint.

Based on the findings from the medical history, physical examination, and any necessary imaging or nerve tests, the healthcare professional can determine the likely cause of the scapular winging and develop an appropriate treatment plan.

Physiotherapy Treatment winging of scapula ?

Physiotherapy plays a crucial role in the treatment of scapular winging.

The primary goals of physiotherapy are to improve scapular stability, strengthen the surrounding muscles, correct muscle imbalances, and restore normal shoulder function.

The specific treatment plan may vary depending on the underlying cause and severity of the winging.

Here are some common physiotherapy interventions for scapular winging:

Muscle strengthening exercises:

A physiotherapist may prescribe specific exercises and stretches based on the patient’s condition, strength, symptoms, and movement pattern.

These exercises may include scapular protraction and retraction exercises, shoulder blade squeezes, wall push-ups, and shoulder strengthening exercises using resistance bands or weights.

Range of motion exercises:

Gentle stretching exercises may be advised to improve the flexibility and mobility of the shoulder joint.

These exercises may target the chest muscles (pectoralis major and minor), posterior shoulder muscles and the muscles around the neck and upper back.

Scapular retraining:

Physiotherapists may use specific techniques to help retrain and reeducate the muscles around the scapula for improved stability and control.

This may involve exercises focusing on scapular control and proper movement patterns during functional activities.

Posture correction:

Physiotherapists can provide guidance on maintaining appropriate posture during daily activities and at rest. Proper body mechanics can help reduce unnecessary stress and strain on the shoulder and scapular region.

Modalities and manual therapy:

Depending on the individual’s needs, a physiotherapist may incorporate modalities such as heat or cold therapy, ultrasound, electrical stimulation, or soft-tissue mobilization to help manage pain or muscle tightness when clinically appropriate.

Activity modification and ergonomic advice:

Physiotherapists can provide guidance on modifying activities and workplace ergonomics to prevent further aggravation and support optimal scapular function.

Home exercise program:

A personalized home exercise program may be prescribed to help continue the rehabilitation process between physiotherapy sessions.

Consulting a qualified physiotherapist who specializes in shoulder and scapular rehabilitation can help ensure an appropriate assessment and individualized treatment plan. The physiotherapist can guide you through suitable exercises and monitor your progress during rehabilitation.

When Should You See a Doctor or Physiotherapist?

A shoulder blade that appears to stick out does not always require urgent treatment, but persistent, worsening, painful, or function-limiting scapular winging should be assessed by a qualified healthcare professional. An examination can help determine whether the problem is related to muscle weakness, altered scapular movement, nerve dysfunction, injury, or another shoulder condition.

Arrange a Professional Assessment If:

• The winging is getting worse or becomes increasingly noticeable over time.
• You have persistent shoulder or upper-back pain that does not improve with appropriate self-care.
• Your arm feels weak or you have difficulty lifting, pushing, pulling, or performing overhead activities.
• The winging appeared after an injury, such as a fall, shoulder injury, or other trauma.
• You notice neurological symptoms, such as unusual numbness, tingling, or significant weakness.
• Your shoulder movement is becoming restricted or normal daily activities are becoming difficult.
• The shoulder blade protrusion persists despite appropriate exercises or activity modification.

Why assessment matters:

Treatment should be based on the underlying cause. A physiotherapist, orthopedic specialist, or other appropriate healthcare professional may assess your shoulder movement, muscle strength, joint function and neurological signs and decide whether further testing is necessary.

Seek prompt medical attention:

If shoulder-blade changes occur suddenly with significant weakness, severe pain, major trauma, or other concerning neurological symptoms, seek medical evaluation rather than relying only on home exercises.
