winging of scapula nerve
A winged scapula is where the scapula protrudes from the patient's back and can affect the ability to lift objects or pull and push. Scapular winging involves one or both shoulder blades sticking out from the back rather than lying flat. It must be recognized that scapular winging is not simply an aesthetic issue; the compensatory muscular activity required to improve Numerous underlying etiologies have been described. These muscles are innervated by the dorsal scapular nerve, which travels from the lower cervical spine down the posterior thoracic region where . Lesions of the long thoracic nerve and spinal accessory nerves are the most common cause.

Scapular winging is a dysfunction involving the stabilizing muscles of the scapula resulting in imbalance and abnormal motion of the scapula. The nerve then travels along the lateral aspect of the chest wall superficially, making it susceptible nerve root. Scapulothoracic Winging (Mena Mesiha MD, Paul Yannopoulos BA, JP Warner, MD) April 2013 Fig. Scapular winging can also be the product of injury to the spinal accessory nerve (cranial nerve 12) . This is typically due to damage (i.e. The serratus anterior protracts and upwardly rotates the scapula. What Is a Winged Scapula? Winging of the scapula due to long thoracic nerve (LTN) injury is a fairly common diagnosis and should be treated as a significant functional problem. The scapula, otherwise known as the shoulder blade, connects the upper arm with the collar bone. In trapezius palsy (spinal accessory nerve), the sh This is an uncommon condition and may arise from traumatic injury to the nerve supplying the serratus anterior muscle, the long thoracic nerve; or due to damage to the nerve from pressure lesions or a neuritis (inflammation of the nerve). Scapula winging is characterized by a failure of the dynamic stabilizing structures that keep the scapula anchored to the chest wall, leading to a prominence of the scapula (Fig. Scapular winging more recently has been classified anatomically, based on whether the etiology of the lesion is related to nerve, muscle, bone, or joint disease. Winged scapula usually occurs when there is damage or impaired innervation to the serratus anterior muscle from the long thoracic nerve - resulting in weakness of the Serratus anterior muscle, as well as other muscles around the shoulder blade. Lesions of the long thoracic nerve and spinal accessory nerves are the most common cause. A case of a 51-year-old man who had right shoulder pain, weakness of right arm elevation, and prominence of right scapula for 6 months is presented. Disruption of the muscles function could lead to abnormal motion of the scapula, which is known as 'scapular dysrhythmia' or 'scapular dyskinesia'. It must be recognized that scapular winging is not simply an aesthetic issue; the compensatory muscular activity required to improve shoulder stability is associated with secondary pain and spasm due to muscle imbalances and tendonitis around the shoulder joint. My recommendation: Get EMG testing of the nerve to see if there are any issues with the electrical signals. The main indication of scapular winging is one shoulder blade sticking out from the back. The term 'winged scapula' (also scapula alata) is used when the muscles of the scapulaare too weak or paralyzed, resulting in a limited ability to stabilize the scapula. Scapular Winging: An Update Abstract Scapular winging is a rare disorder often caused by neuromuscular imbalance in the scapulothoracic stabilizer muscles. This nerve supplies the serratus anterior, which is located on the side of the thorax and acts to pull the scapula forward. A winged scapula is typically caused by damage to a nerve known as the long thoracic nerve. It's surrounded by muscles and helps provide stability and movement to the arm. The winging of the scapula seen with dorsal scapular nerve . lesions) of the long thoracic nerve. As a result, the inferior angle of the scapula protrudes backwards and can easily be seen through the skin of the patient due to . A winging scapula is associated with damage or a contusion to the long thoracic nerve of the shoulder and / or weakness in the serratus anterior muscle. scapular winging. Dr. Rahul Nath is director of the Texas Nerve Institute in the Texas Medical Center specializing in winging scapula, serratus anterior and long thoracic nerve. If there is severe acute pain in addition to winging of the scapula, this is a sign of brachial neuritis that needs to be excluded. Abstract. Dorsal scapular nerve entrapment is a very under-recognized cause of neck and shoulder pain. Medial winging is more common, being caused by serratus anterior paralysis. Scapular winging often leads to pain and functional limitations. Weakness or loss of scapular mechanics can lead to difficulties with elevation of the arm and lifting objects. As a result, winging of the scapular or shoulder blade occurs. This represents a more significant issue, such as a nerve injury. Medial winging is more common, being caused by serratus anterior paralysis. Scapular Winging: An Update Abstract Scapular winging is a rare disorder often caused by neuromuscular imbalance in the scapulothoracic stabilizer muscles. 19, 38 Paralysis of the trapezius results in drooping of the entire shoulder girdle, winging and lateral displacement of the scapula, and weakness in forward elevation and abduction. The nerve that innervates this muscle is the long thoracic nerve. Winging of the scapula due to long thoracic nerve palsy is a common diagnosis 1,2,3,4,5,6,7,8,9,10 and should be treated as a significant functional problem. scapular winging. With a reduced function in the Serratus muscle, the shoulder blade will raise into a winging . The symptoms of scapular winging can depend on the location of the nerve or muscle damage. Dorsal scapular nerve syndrome typically presents with a weakness of the levator scapulae and the rhomboid muscles, and results in a winged scapula. Sometimes a winging scapula is caused [] The long thoracic nerve originates from the ventral rami of the C5, C6, and C7 cervical nerves and travels beneath the brachial plexus and clavicle over the first rib. Patients report diffuse neck, shoulder girdle . These stabilizers are comprised of three main muscle groups: serratus anterior, trapezius and rhomboids major and minor. Physical examination revealed a winged scapula and Figure 2 Scapular winging at different angles of arm abduction. If the long thoracic nerve is damaged or bruised it can cause paralysis of the serratus anterior muscle and winging of the scapular or shoulder blade. As a result, the medial or lateral borders of the scapula protrudes from back, like wings. Let's use a nice quote from the paper to get more specific. A winging scapula has several different causes. Scapula winging or a winged scapula is rare condition that causes the shoulder blade to stick out from the back. (Concave-Convex . The scapula with its muscular attachments is vital to the function of the upper extremity particularly with overhead motions. A winging scapula is associated with damage or a contusion to the long thoracic nerve of the shoulder and / or weakness in the serratus anterior muscle. It can happen as a result of injury or nerve damage. Scapular winging secondary to serratus anterior muscle palsy is a rare pathology. Winged scapula is a condition characterized by lateral or medial protrusion of the scapula caused by nerve damage leading to muscular paralysis. During motion, the muscle weakness is manifested as winging of the scapula (the . Now ask the patient to slowly extend their shoulder and examine the scapula during this motion. The nerve is often injured during first rib resection for thoracic outlet syndrome. Winging of the scapula due to long thoracic nerve palsy is a common diagnosis and should be treated as a significant functional problem. Scapular winging is a painful and debilitating condition. Numerous underlying etiologies have been described. The nerve then travels along the lateral aspect of the chest wall superficially, making it susceptible Scapular winging is a rare condition that results in abnormal scapular motion, causing pain and decreased functionality of the upper extremity. What causes a winging scapula? The main reasons for this condition are musculoskeletal- and neurological-related. He was unable to abduct his right arm recording from the trapezius, produced no compound above 80 in the frontal or scapular plane while his for- muscle . Scapular Winging Syndrome This syndrome is characterized by an inability to elevate and/ or lower the arm without the scapula winging or its inferior angle tilting. There is an association with numerous medical conditions or injuries that ultimately affect glenohumeral and scapulothoracic biomechanics. If the long thoracic nerve is damaged or bruised it can cause paralysis of the serratus anterior muscle. Injury to the spinal accessory (eleventh cranial) nerve can cause significant dysfunction of this muscle. The condition had been abruptly developed . The scapula, also known as the shoulder blade, is the triangular shaped bone that sits against the rib cage on the outer portion of the upper back. Neurogenic causes of scapular winging asymmetry of his shoulders, with right shoulder depres- sion (Figure 1). I'm going to reference Scapular winging: anatomical review, diagnosis, and treatments often. 4, 9, 22 This constellation of symptoms can lead to . The shoulder blade and rib cage have a matching curved shape. Flat thoracic spine. Keywords Scapular winging Serratus anterior Trapezius Rhomboid Long thoracic nerve Introduction Scapular winging is a rare, but potentially debilitating condition that can affect the ability to lift, pull, and push heavy objects, as well as to perform daily activities of living, such as brushing one's hair and teeth and carrying grocery bags [1]. Scapular winging is an uncommon nerve condition, causing pain and occasionally weakness in the shoulder. What causes medial wingin. Pictures and bolding from me: "The serratus The control of the scapula relies on well co-ordinated motion of the multiple muscles attached to the scapula. DEFINATION : The term 'winged scapula' (also scapula alata) is used when the muscles of the scapula are too weak or paralyzed, resulting in a limited ability to stabilize the scapula. Most people will not have a large winging of their scapula while elevating their arms. Serratus Anterior is responsible for keeping the shoulder blade (Scapula) stabile and in the right movement. In patients with lateral winging, assess the dorsal scapular nerve. Scapula Alata is caused by an affection of the nerve Thoracicus Longus, resulting in a reduced function of the muscle Serratus Anterior. This can cause pain in completing normal activities like slipping on a shirt or brushing teeth. Winging of the scapula Common neurogenic causes of scapular winging are serratus anterior, trapezius and rhomboid palsy. This is an uncommon condition and may arise from traumatic injury to the nerve supplying the serratus anterior muscle, the long thoracic nerve; or due to damage to the nerve from pressure lesions or a neuritis (inflammation of the nerve). The shoulder blade is also known as scapula, and the term scapular winging is used to describe this abnormal positioning of the shoulder blade, with various degrees of visible prominence. The LTN originates from the cervical 5,6 and 7 nerve roots and innervates the serratus anterior muscle. - Anatomy of scapular winging (muscular) Serratus anterior Of course, we have to start with this muscle. The Problem. As a result, the medial border of the scapula protrudes, like wings. Akgun K, Aktas I, Terzi Y. Winging of the scapula due to long thoracic nerve palsy is a common diagnosis and should be treated as a significant functional problem. Numerous underlying etiologies have been described. It is the result of numerous causes, including traumatic, iatrogenic, and idiopathic processes that most often result in nerve injury and paralysis of either the . It involves injury to the long thoracic nerve in the back near the shoulder blade. Weakness and fatigue of the rhomboid and levator scapulae muscles can produce mild winging of the scapula and a lack of shoulder stabilization. If the long thoracic nerve is damaged or bruised it can cause paralysis of the serratus anterior muscle and winging of the scapular or shoulder blade. The pain of winged scapula syndrome is aching and is localized to the muscle mass of the posterior chest wall and scapula. The scapular winging may be subtle, and the symptoms are easily mistaken for other problems. The purpose of this systematic review of literature is to evaluate the current research literature related to the effectiveness of therapy options for winged scapula. Dorsal scapular nerve lesions are quite rare. This is typically due to damage (i.e. The long thoracic nerve originates from the ventral rami of the C5, C6, and C7 cervical nerves and travels beneath the brachial plexus and clavicle over the first rib. Scapular winging is a rare disorder often caused by neuromuscular imbalance in the scapulothoracic stabilizer muscles. One common cause is an injured long thoracic nerve due to overuse in sports or other activities. The LTN originates from the cervical 5,6 and 7 nerve roots and innervates the serratus anterior muscle. Neurologic examination can point to the nerve involved. Medial winging is more common, being caused by serratus anterior paralysis. Fixing a winged scapula is a matter of determining what is causing it. It is usually due to a lesion in the thoracic part of the long thoracic nerve following violent upper-limb stretching with compression on the nerve by the anterior branch of thoracodorsal artery at the "crow's foot landmark" where the artery crosses in front of the nerve. Winged scapula is a common diagnosis affecting shoulder stability and should be treated as a significant functional problem. ). 1: (left side)Normal Scapular rotation (right side) Scapular winging. Scapular winging secondary to serratus anterior muscle palsy is a rare pathology. The main reasons for this condition are musculoskeletal- and neurological-related. Since the scapula sticks straight out, it resembles a wing, which gives rise to the name of this condition. Serratus anterior palsy as a result of long thoracic nerve injury is most common cause of scapular winging. 4. Primary scapular winging may be due to neurologic injury, pathologic changes in the bone, or periscapular soft-tissue abnormalities. Deformity is minimal in serratus anterior palsy (long thoracic nerve); winging is accentuated by forward elevation and pushing with outstretched arms. Dr. Nath, board-certified surgeon and founder of Texas Nerve & Paralysis . The levator scapulae elevates the scapular and tilts . Apparently, the first surgeon who wrote about scapular winging was Dr. Velpeau, from France, in 1825 (almost 200 hundred years ago! The most common causes What causes scapular winging? The long thoracic nerve runs from the neck along the chest wall to the serratus anterior muscle. Winging of the scapula due to long thoracic nerve (LTN) injury is a fairly common diagnosis and should be treated as a significant functional problem. lesions) of the long thoracic nerve. Lateral scapular winging: Inferior pole of scapula depressed and laterally shifted. This syndrome results from a weakness and adaptive shortness of the serratus anterior, with accompanying shortness of the pectoralis minor and scapulohumeral muscles. Surgery to the axilla, e.g. It can be classified as primary, secondary, or voluntary. Injury to the long thoracic nerve denervates the serratus anterior muscle, resulting in scapular winging and shoulder instability. While shoulder blades typically sit flat against the back of the chest wall, scapular winging refers to a shoulder blade that is sticking out. EMG and nerve studies are very helpful in diagnosing problems of the long thoracic nerve. Serratus anterior muscle weakness (long thoracic nerve) causes medial winging of the scapula, which is more prominent with forward shoulder Epidemiology. A winged scapula is associated with damage or a contusion to the long thoracic nerve of the shoulder and/or weakness in the Serratus Anterior muscle. Scapular winging is a rare debilitating condition that leads to limited functional activity of the upper extremity. Winged scapula is caused by paralysis of the serratus anterior or trapezius muscles due to damage to the long thoracic or accessory nerves, resulting in loss of strength and range of motion of the shoulder. What is the Winged Scapula? Winged scapula caused by a dorsal scapular nerve lesion: a case report. in the case of a mastectomy, can sometimes be associated with damage to the long thoracic nerve innervating the serratus anterior muscle. Damage to the nerve can be caused by a . Lesions of the long thoracic nerve and spinal accessory nerves are the most common cause.
