Post-Mastectomy Axillary Web Syndrome (Cording): Lymphatic Cord Mobilization & Shoulder ROM
In short
A tight, guitar-string cord running down your armpit to your wrist makes raising your arm excruciating. Learn how specialized physiotherapy gently releases axillary web syndrome.

What is Axillary Web Syndrome (AWS) or 'Cording'?
Axillary Web Syndrome (AWS), commonly known as 'cording', is a frequent complication following breast cancer surgery involving the axilla, occurring in 20 to 50 percent of women following axillary lymph node dissection (ALND) or sentinel lymph node biopsy (SLNB). It typically presents 1 to 8 weeks postoperatively.
Patients notice one or more visible, taut, fibrous cords resembling guitar strings running through the axilla, extending down the medial aspect of the arm, crossing the antecubital fossa, and occasionally reaching the base of the thumb. These cords produce severe tightness and sharp pain, severely restricting shoulder abduction and elbow extension.
Anatomical Pathophysiology of the Cords
Histological and ultrasound investigations confirm that the cords are not tendons or nerves; they are thrombosed, fibrosed, and hyperplastic lymphatic vessels and superficial veins (a localized form of superficial lymphovasculitis and Mondor's disease).
Disruption of axillary lymphatic flow during surgery causes stasis, endothelial inflammation, and subsequent fibrinous deposition within the lymphatic channels. As the fibrous bands contract, they tether surrounding subcutaneous tissues to the deep axillary fascia.
| Diagnostic Feature | Axillary Web Syndrome (Cording) | Rotator Cuff Tendinopathy / Frozen Shoulder | |
|---|---|---|---|
| Visible / Palpable Signs | Distinct, raised, cord-like bands visible on abduction | No visible cords; diffuse joint fullness or atrophy | |
| End-Feel Restriction | Elastic, taut leash end-feel; visible skin tenting | Firm capsular or sharp impingement end-feel | |
| Position of Maximal Tension | Combined shoulder abduction, elbow extension, wrist extension | Passive glenohumeral internal/external rotation | |
| Response to Cord Release | Immediate, dramatic 15-30 deg increase in shoulder ROM | Gradual improvement over weeks of joint mobilization | |
| Aggressive Forcible Stretching | Harmful; causes cord inflammation and micro-tears | Harmful; causes reactive capsular guarding |
Targeted Physiotherapy: Gentle Cord Mobilization
Treatment requires high skill: aggressive forcible stretching can tear lymphatic channels, provoke severe pain, and increase the risk of secondary lymphedema. Instead, physiotherapists apply gentle, progressive tissue mobilization.
Techniques include transverse friction across the cord, skin rolling to separate the bands from overlying dermis, and gentle nerve-gliding motions to liberate the median nerve from adjacent fascial tethering.
- Transverse Cord Friction: Gentle strumming perpendicular to the cord fibers at the level of the arm and elbow, softening the dense fibrin matrix.
- Low-Load Prolonged Tissue Elongation: Supporting the arm in a comfortable abductor position on pillows, applying moist heat to surrounding muscles before gentle active-assisted stretching.
- The 'Snap' or 'Pop' Phenomenon: Patients occasionally feel an audible or tactile pop during therapy, followed by immediate relief; this represents the rupture of a fibrosed lymphatic channel, which is benign and non-injurious.
Restoring Full Upper Limb Function
Once cord tension begins resolving, therapy progresses to active functional range of motion: wall-crawling exercises, wand exercises, and gentle periscapular stabilization to prevent compensatory shoulder hiking and subacromial impingement.
Frequently Asked Questions
How long does axillary web syndrome take to resolve?
With targeted, gentle physiotherapy, most cases of AWS resolve within 4 to 8 weeks, restoring full shoulder elevation and arm extension.
Will having cording cause lymphedema?
While AWS indicates lymphatic disruption, having cording does not mean you will definitely develop lymphedema. However, prompt treatment prevents chronic tissue tension and protects lymphatic drainage.
Should I try to vigorously pop or snap the cord at home?
No. Never attempt to forcefully snap the cords with aggressive pulling, as this can cause hematoma formation or soft tissue inflammation. Gentle, patient mobilization is much safer.
