Winged Scapula: Causes, Physiotherapy Exercises & Full Recovery Guide

Winged Scapula: Understanding and Treating Scapular Winging

A winged scapula is characterized by the medial border of the scapula (shoulder blade) lifting away from the posterior rib cage, making it look like a wing. It is visible at rest or becomes prominent when the arm is elevated or when pushing against a wall.

Anatomy: What Normally Holds the Scapula Flat?

The scapula is held against the chest wall by three key muscles:

1. Serratus anterior (innervated by long thoracic nerve, C5-C7): The primary stabilizer — wraps around the rib cage and pulls the inferior angle forward and laterally
2. Trapezius (innervated by spinal accessory nerve, CN XI): Upper, middle, and lower fibres control scapular elevation, retraction, and depression
3. Rhomboids (innervated by dorsal scapular nerve): Retract and rotate the scapula downward

When serratus anterior is paralyzed or significantly weak, the medial border of the scapula wings outward during arm elevation.

Types of Scapular Winging

Medial winging (most common): Long thoracic nerve palsy → serratus anterior weakness → medial border lifts during forward arm elevation.

Lateral winging: Trapezius palsy (spinal accessory nerve) → the scapula rotates laterally → lateral border and inferior angle wing outward during abduction.

Physiotherapy Exercise Programme

1. Push-Up Plus (Primary Exercise)

Standard push-up position (or modified on knees). Perform push-up. At the top, continue pushing through the hands to protract (push forward) the scapulae — so the area between the shoulder blades spreads apart. Return slowly. 3 × 12 reps. Directly activates serratus anterior through its full functional range.

2. Wall Push-Up Plus (Beginner)

Stand facing wall. Hands shoulder-width, elbows straight. Push through hands to round the upper back forward (protract scapulae). Return. Easier load for initial stages. 3 × 15 reps.

3. Serratus Punch (Supine)

Lie on back. Hold weight (0.5–2 kg) directly above shoulder. Keeping elbow straight, punch upward (protract scapula off the surface). Lower with control. 3 × 15 reps.

4. Scapular Clock Exercise

Standing with arm extended forward at 90°. Imagine a clock face on the wall. Move the arm through the clock positions while maintaining scapular protraction. Trains dynamic stabilization.

5. Resistance Band Serratus Activation

Band anchored at shoulder height. Step back to create tension. With arm extended, push forward and protract — eccentric return phase. 3 × 12.

6. Scapular Taping

KT tape applied from mid-scapula to mid-thoracic spine provides proprioceptive cuing for correct scapular position throughout the day — particularly useful for neurological winging during recovery.

For Nerve-Related Winging (Long Thoracic Nerve Palsy)

While awaiting nerve recovery:

• FES (Functional Electrical Stimulation): Applied over serratus anterior to maintain muscle bulk and facilitate voluntary activation as nerves regenerate
• Scapular support orthosis: Reduces the stretch on recovering nerve fibres
• Compensatory trapezius training: Lower trapezius and rhomboids partially compensate for serratus deficit

Recovery time: Neuropraxia (bruising) — 6–12 weeks. Axonotmesis (structural damage) — 6–24 months.
