the rib cage when a person pushes against a wall is not always a simple posture problem. One important, although uncommon, cause is palsy or neuropathy of the <strong>long thoracic nerve<\/strong>. This nerve supplies the serratus anterior, a muscle essential for holding the scapula against the thorax and rotating it upward during arm elevation.<\/p>\n<p>When the serratus anterior becomes weak, the medial border of the scapula can protrude: this is <strong>scapular winging<\/strong>. The patient may have difficulty raising the arm, pushing, carrying, or sustaining overhead activity. Some also report fatigue, pain around the scapula, and reduced power.<\/p>\n<p>For the osteopath, this matters because the presentation can resemble ordinary scapular dyskinesis. True long thoracic nerve injury, however, is a neuropathy and requires accurate diagnosis, often with electromyography and sometimes ultrasound or MRI. Manipulation does not instantly restore a denervated nerve.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"Anatomy_of_the_Long_Thoracic_Nerve\"><\/span>Anatomy of the Long Thoracic Nerve<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>The long thoracic nerve arises mainly from C5, C6, and C7. It descends along the lateral chest wall and supplies the serratus anterior at several levels.<\/p>\n<p>Its long and relatively superficial course exposes it to traction, trauma, surgery, and some inflammatory neuropathies.<\/p>\n<p>The serratus anterior contributes to:<\/p>\n<ul>\n<li>holding the scapula against the chest wall;<\/li>\n<li>scapular protraction;<\/li>\n<li>upward rotation during arm elevation;<\/li>\n<li>stabilizing the shoulder girdle during pushing and sport.<\/li>\n<\/ul>\n<h2><span class=\"ez-toc-section\" id=\"What_Does_Scapular_Winging_Look_Like\"><\/span>What Does Scapular Winging Look Like?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>With serratus anterior dysfunction, the medial border and inferior angle of the scapula become more prominent, especially during a wall push or arm elevation.<\/p>\n<p>The deformity may be subtle at rest and obvious during effort.<\/p>\n<p>The patient may compensate by shrugging or leaning the trunk to help elevate the arm.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"What_Can_Cause_It\"><\/span>What Can Cause It?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>Long thoracic neuropathy can occur after:<\/p>\n<ul>\n<li>trauma;<\/li>\n<li>repetitive movement or intense effort;<\/li>\n<li>thoracic, breast, or axillary surgery;<\/li>\n<li>prolonged load carrying;<\/li>\n<li>sport;<\/li>\n<li>neuralgic amyotrophy or Parsonage-Turner syndrome;<\/li>\n<li>an idiopathic episode.<\/li>\n<\/ul>\n<p>A 2023 review emphasizes that natural history is not as uniformly favourable as was once believed: some patients recover spontaneously, while others retain weakness, fatigue, and residual winging [1].<\/p>\n<h2><span class=\"ez-toc-section\" id=\"Can_Sport_Cause_Long_Thoracic_Neuropathy\"><\/span>Can Sport Cause Long Thoracic Neuropathy?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>Cases have been described after weight training, throwing, swimming, racket sports, or carrying heavy bags. Mechanisms may involve repetitive traction, compression, or inflammation.<\/p>\n<p>But altered scapular motion in an athlete does not automatically mean nerve injury.

It can occur with shoulder pain, muscle weakness, fatigue, or motor strategy.<\/p>\n<p>The key difference is that long thoracic neuropathy causes serratus anterior weakness that can be documented electrophysiologically.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"Differential_Diagnosis_Spinal_Accessory_Nerve\"><\/span>Differential Diagnosis: Spinal Accessory Nerve<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>Spinal accessory nerve injury weakens the trapezius and can also cause winging, but the pattern differs. The shoulder may droop, winging can become more obvious during abduction, and trapezius weakness is apparent.<\/p>\n<p>The examination should therefore compare serratus anterior and trapezius function.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"Differential_Diagnosis_Dorsal_Scapular_Nerve\"><\/span>Differential Diagnosis: Dorsal Scapular Nerve<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>The dorsal scapular nerve mainly supplies the rhomboids. Its injury can produce subtler winging and weak retraction.<\/p>\n<p>Marked medial winging during a wall push is more suggestive of serratus anterior dysfunction.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"Differential_Diagnosis_Shoulder_Disease\"><\/span>Differential Diagnosis: Shoulder Disease<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>A rotator-cuff tear, severe pain, or glenohumeral stiffness can alter scapular motion without neuropathy.<\/p>\n<p>A complete shoulder examination is therefore necessary.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"How_Is_the_Diagnosis_Confirmed\"><\/span>How Is the Diagnosis Confirmed?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>Clinical examination observes scapular movement, pushing strength, and arm-elevation ability.<\/p>\n<p>Electromyography of the serratus anterior is often used to confirm denervation and follow recovery.<\/p>\n<p>High-resolution ultrasound is also becoming more useful. A recent technical publication describes ultrasound evaluation of the long thoracic nerve and image-guided approaches in neuropathy [2].<\/p>\n<h2><span class=\"ez-toc-section\" id=\"Muscle_Imaging\"><\/span>Muscle Imaging<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>MRI can show denervation edema and, in chronic cases, fatty atrophy of the serratus anterior.<\/p>\n<p>It may also help investigate another pain source or a brachial-plexus disorder.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"How_Long_Should_Recovery_Be_Observed\"><\/span>How Long Should Recovery Be Observed?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>Historically, it was often taught that most patients would recover spontaneously within two years.

The sign often becomes obvious when the patient pushes against a wall or attempts to elevate the arm.<\/p>\n<p>Diagnosis requires distinguishing neuropathy from ordinary scapular dyskinesis, spinal accessory nerve injury, and shoulder disease.<\/p>\n<p>For the osteopath, the best strategy is not to reduce the problem to a scapula that is \u201cout of place.\u201d Function should be preserved, recovery supported, and a neurological deficit investigated appropriately.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"Why_Shoulder_Function_May_Remain_Limited_Even_as_the_Nerve_Recovers\"><\/span>Why Shoulder Function May Remain Limited Even as the Nerve Recovers<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>Nerve recovery is only one part of the process. After months of winging, the patient may have lost endurance, avoided certain movements, and developed compensations through the trapezius, neck, or trunk. Even when EMG shows reinnervation, the serratus anterior must regain the ability to work for long periods and coordinate the scapula with the arm.<\/p>\n<p>Rehabilitation should therefore continue beyond the first return of strength. For an athlete or overhead worker, the final goal is repeated activity without excessive fatigue, not simply one successful arm elevation.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"References\"><\/span>References<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<ol>\n<li>Wu F, Ng CY.
