Winged Scapula

Quick answer: A winged scapula is a shoulder blade that lifts away from the rib cage instead of lying flat against it. Marked winging is most often caused by a problem with a nerve that controls one of the shoulder blade muscles, and that needs a doctor. Milder winging, where the shoulder blade sits a little off the ribs, is common and usually reflects posture and muscle balance around the shoulders, which is something you can work on.

Maybe you’ve noticed one shoulder blade sticking out in a photo or the mirror, or someone pointed it out at the gym. Maybe it shows most when you push against something, or your shoulder feels weak lifting overhead. The first thing to work out is which kind you’re looking at.

What Is a Winged Scapula?

Your shoulder blades (scapulae) glide over the back of your rib cage, held in place by several muscles, most importantly the serratus anterior, which wraps around the side of the ribs, and the trapezius. When one of these muscles isn’t holding the blade against the ribs, its edge lifts away, like a wing.

Nerve-Related vs. Postural Winging

Nerve-related winging. Most pronounced scapular winging comes from the serratus anterior not working because its nerve, the long thoracic nerve, has been injured or irritated. That can follow a blow to the shoulder or neck, heavy or repetitive overhead strain, surgery near the armpit or chest (such as some breast surgery), or even a viral illness. Less often, a different nerve affecting the trapezius is involved. This kind is usually obvious, often one-sided, and comes with weakness lifting the arm. It needs a doctor, and exercise alone won’t fix a nerve problem.

Postural winging. More often, the shoulder blade simply sits slightly off the ribs because of how the shoulders and upper back are positioned. Rounded shoulders, a rounded upper back (hunchback) and a forward head tip the shoulder blades forward, and the muscles that should hold them flat don’t get the chance to work. This kind is usually milder, often on both sides, and tends to respond to posture work.

How Can I Tell If I Have a Winged Scapula?

1. Mirror or photo check. With your shirt off or in a tank top, have someone photograph your back while you stand relaxed. Does the inner edge or lower tip of one shoulder blade lift away from your back?
2. Wall push-up check. Stand facing a wall and do a slow push-up against it. Ask someone to watch your shoulder blades. Does one lift away noticeably as you push?
3. Arm raise check. Raise your arms forward and overhead. Is it harder on one side, or does one shoulder blade stick out more as you lift?
4. Comparison check. Is it one side or both? Did it appear suddenly or after an injury or surgery?

If the winging is marked, one-sided, appeared suddenly, or comes with weakness raising your arm, see a doctor before starting exercises. They can check the nerves and muscles, sometimes with a nerve test.

What Causes Postural Winging?

• Rounded shoulders and upper back. Long hours hunched over desks and screens tip the shoulder blades forward.
• Muscle balance. A tight chest and under-used muscles around the shoulder blades, especially the serratus anterior and lower trapezius.
• Training habits. Lots of pushing and chest work without matching upper-back work.
• What’s happening below. How the pelvis and trunk are positioned changes how the rib cage sits, and the shoulder blades sit on the rib cage. See uneven shoulders.

What Are the Symptoms?

Postural winging often causes no symptoms. When there are symptoms, people commonly describe:

• Aching around the shoulder blade or back of the shoulder
• Fatigue or weakness when lifting or reaching overhead
• Discomfort leaning back against a chair
• Neck and upper-back tension

See a doctor if you have sudden winging, marked weakness raising your arm, numbness or tingling in your arm, or winging after an injury or surgery.

How Do You Fix Postural Winging?

Many people go straight to strengthening the “weak” muscle. That can help, but if the upper back is still rounded and the shoulders still roll forward, the shoulder blade has no stable surface to sit on, and the winging comes straight back.

What tends to help is changing the position the shoulder blades live in: restoring movement in the upper back, opening the chest, and teaching the muscles around the shoulder blades to hold them flat, working up from the pelvis and trunk. How much the winging changes varies from person to person. Nerve-related winging is different and is managed by a doctor; posture work can sit alongside that care.

Exercises for Postural Winging

Three starting points. Move slowly and stop anything that causes pain. If a doctor is managing nerve-related winging, check with them first.

1. Sitting Arm Circles

Sit tall on the front of a chair, rolling your hips forward onto your sit bones with a gentle arch in your lower back. Squeeze your shoulder blades back and down, and curl your fingertips into a loose fist. Raise your arms out to the sides at shoulder height and make small circles rolling up and forward, 25 to 50 times. Then turn your palms up and do the same number rolling up and back.

2. Elbow Curls

Stand or sit tall. Curl your fingertips and rest your knuckles on your temples, thumbs pointing down, chin level. Bring your elbows together in front of your face, then open them back until they line up with your ears. Repeat 20 to 25 times, slowly, feeling your shoulder blades draw together as you open.

3. Cats and Dogs

Start on your hands and knees, wrists under your shoulders and knees under your hips. Let your back and shoulder blades drop gently toward the floor. Breathing out, round your spine from your tailbone up through your upper back, pushing the floor away so your shoulder blades spread apart. As you breathe in, let your back sink back down. Repeat 10 times.

Choosing Your Next Step

There’s no single right path. It depends on how you like to work:

• You’d like to start on your own. If your winging is mild and postural, the checks and exercises above are a sensible place to begin.
• You’d like someone to find what’s driving it. A free 30-minute consultation includes a postural assessment of your shoulders, upper back and the rest of your body. We have clinics in Newton, Gloucester, Santa Monica, Beverly Grove and Middletown, RI.
• You’re not near a clinic. Virtual posture therapy brings the same assessment approach to you.

Frequently Asked Questions About Winged Scapula

Is a winged scapula serious?

Mild postural winging usually isn’t. Marked, sudden or one-sided winging, especially with weakness raising the arm, can mean a nerve is involved and should be checked by a doctor.

Can a winged scapula be fixed?

Postural winging often improves with consistent work on the shoulders, upper back and trunk. Nerve-related winging depends on the nerve’s recovery, which a doctor manages; many nerve injuries recover over time, and posture work can support that care.

What muscle is weak with a winged scapula?

Most often the serratus anterior, which holds the shoulder blade against the ribs. The trapezius and rhomboids can also be involved. In postural winging, the issue is usually how these muscles are being used, rather than a nerve problem.

Can push-ups fix a winged scapula?

They can help strengthen the serratus anterior, but only if the shoulder blades are well positioned while you do them. If the upper back is rounded, push-ups can reinforce the pattern. With nerve-related winging, check with your doctor first.

This article is general education, not medical advice. If your winging appeared suddenly, is marked or one-sided, followed an injury or surgery, or comes with arm weakness, numbness or tingling, see a physician first. Posture therapy works alongside medical care, never instead of it.
