A winged scapula is a shoulder blade that lifts away from the rib cage instead of lying flat against it. Usually it is scapular dyskinesis: the muscles holding the blade are weak, tired or inhibited by shoulder pain, and it responds to exercise. Less often a nerve has stopped working, usually the long thoracic nerve to serratus anterior, and that needs a doctor first.
What causes a winged scapula?
Two groups. In nerve-related winging, one nerve stops supplying one muscle and the blade lifts visibly. In scapular dyskinesis, the nerves work but the blade moves out of rhythm through weakness, fatigue or pain. The second is far more common.
| Nerve | Muscle | What you see | Common causes |
|---|---|---|---|
| Long thoracic nerve | Serratus anterior | Medial winging: inner border and lower tip lift, worst pushing forward | Heavy shoulder load, a blow to the side of the chest, brachial neuritis, armpit or chest wall surgery |
| Spinal accessory nerve | Trapezius | Lateral winging: blade drifts outward, shoulder droops | Neck surgery or a lymph node biopsy in the neck |
Dyskinesis is a lower tip that lifts a little as the arm comes down from overhead, more when tired. It travels with rotator cuff pain, desk hours, a gym layoff and one-arm sports. Serratus anterior pain, an ache along the side ribs below the armpit, usually means the muscle is overworked, not torn.
How do I tell if my serratus anterior is weak?
Stand an arm’s length from a wall, hands on it at shoulder height, and push away slowly ten times while someone films your back. If the inner border or lower tip lifts like a wing, serratus anterior is not holding the blade. Then raise both arms overhead and lower them slowly. Dyskinesis usually shows on the way down.
Winging at rest, a blade sticking out several centimeters, or an arm that will not go above shoulder height points toward a nerve. A physiotherapist can test each muscle. Confirming a nerve palsy is a doctor’s job, with nerve conduction studies and EMG if needed.
Can you actually fix a winged scapula?
It depends on the cause. Dyskinesis usually responds to graded strengthening over six to twelve weeks. Many long thoracic nerve palsies recover on their own over months, sometimes up to two years. Physiotherapy keeps the shoulder working meanwhile. It cannot speed the nerve.
A small number do not recover, and an orthopedic surgeon may discuss a tendon transfer. Winging after neck surgery or a lymph node biopsy is different. A spinal accessory nerve injury is time-sensitive, because nerve repair usually does better within the first few months. See the surgeon who operated, or your GP, rather than waiting it out.
What exercises work the serratus anterior?
Serratus anterior works when you push the shoulder blade forward around the ribs at the end of a reach. In order, easiest first:
- Wall slides: forearms on the wall, slide up, blades kept wrapped around the ribs.
- Push-up plus: at the top of a push-up, push a little further so the upper back rounds. Wall first, then knees, then floor.
- Serratus punch: lying down, light weight held straight up, punch toward the ceiling and let it sink back.
- Scapular clock: hand on a wall, move the blade slowly to 12, 3, 6 and 9 o’clock.
Move up when you manage three sets of 10 to 15 with no visible winging on film, mild pain at most, settled by morning. If it wings on the last few, stay there.
- Stage 1, Calm & Protect: settle the pain and change the load that set it off.
- Stage 2, Move & Mobilize: shoulder and upper back range, wall slides, the clock.
- Stage 3, Rebuild & Strengthen: the push-up plus ladder, loaded punches, lower trapezius.
- Stage 4, Return & Perform: pressing, overhead lifting and strokes on a counted ladder.
What exercises should I avoid if I have a winged scapula?
Early on, avoid loads the blade cannot hold flat: heavy overhead pressing, dips, heavy bench press, pull-ups to failure, and a heavy bag on one shoulder. They come back when the blade stays flat under lighter versions.
What happens if winged scapula goes untreated?
Dyskinesis is not dangerous, but a blade that does not tilt well leaves less room for the rotator cuff overhead, so it often comes with shoulder pain. With an undiagnosed nerve palsy, the arm tires quickly overhead and the muscles around the blade ache from covering.
Snapping scapula
A grind, click or clunk under the shoulder blade as the arm moves. Often painless. When it hurts, the usual cause is an irritated bursa between blade and ribs, or muscle imbalance, and treatment is conservative first. A hard lump, snapping after a fracture, or pain unsettled after a few months is for a doctor, who may order an X-ray.
When to see a doctor first
- Call 995 for chest pain with breathlessness, sweating, or pain into the arm or jaw.
- Go to the emergency department now after a heavy fall or accident with an arm you cannot lift.
- See a doctor soon if winging appeared over days or weeks after severe shoulder pain that kept you awake, followed neck, armpit or chest surgery, or comes with arm numbness or weakness.
Where are you with this right now?
1. It is settling on its own
The wall push looks flatter on film than a month ago and the ache has eased. Keep the exercises going. You do not need us for this, and we would rather say so.
2. It has stopped improving
You film your back every week and the blade still lifts on the third set. Bench press became the machine, then nothing. The wall push-ups have sat at the same level for two months. Every first visit is one 45-minute Assessment & Treatment, $230, nett, no GST. If it has been months, the Stalled Recovery Review is three appointments over three weeks with the same therapist, $690.
3. A doctor has sent you to us
Your doctor has confirmed a nerve palsy, or ruled one out. Bring the nerve conduction report or referral letter. We test each muscle around the blade, set the load the shoulder can take, and send your doctor what we measured. All of it runs on the four stages of the Phoenix Recovery Protocol.
