1. INTRODUCTION
Cervical rib is one of the most clinically important congenital anomalies of the skeletal system. Although it is often an incidental radiological finding, it may produce a spectrum of neurovascular symptoms grouped under the umbrella term Thoracic Outlet Syndrome (TOS). The condition has intrigued surgeons and physiotherapists alike since its earliest descriptions in the 19th century - Coote first performed surgical excision of a cervical rib in 1861, and Murphy described transaxillary first rib resection in 1910.
The thoracic outlet is an anatomically tight corridor through which critical neurovascular structures must pass on their way from the neck and chest to the upper limb. Any structural anomaly in this region - whether bony, fibrous, or muscular - can compromise these structures and produce the characteristic symptoms of TOS.
2. DEFINITION
A cervical rib is a supernumerary (extra) rib that articulates with the 7th cervical vertebra (C7). It represents a persistence of the costal element (the lateral part of the transverse process) of the C7 vertebra, which in normal development regresses to form only the anterior tubercle of the transverse process.
-
"A cervical rib is an accessory rib articulating with vertebra CVII; the anterior end attaches to the superior border of the anterior aspect of rib I." - Gray's Anatomy for Students
-
"This rib is usually represented by a fibrous band originating from the seventh cervical vertebra and inserting onto the first thoracic rib." - Bailey & Love's Surgery 28th Ed.
The term Thoracic Outlet Syndrome (TOS) refers to the clinical symptom complex arising from compression of the brachial plexus, subclavian artery, and/or subclavian vein at the thoracic outlet due to this or related anomalies.
3. ANATOMY
3.1 The Thoracic Outlet / Thoracic Inlet
The thoracic outlet (strictly speaking, the thoracic inlet or superior thoracic aperture) is bounded by:
- Posteriorly: Body of T1 vertebra
- Laterally: Medial border of the 1st rib on each side
- Anteriorly: Superior border of the manubrium sterni
3.2 Key Anatomic Spaces
Three important corridors through which neurovascular structures pass:
| Space | Boundaries | Structures Passing Through |
|---|---|---|
| Interscalene Triangle | Anterior scalene (anterior), middle scalene (posterior), 1st rib (floor) | Subclavian artery, brachial plexus |
| Costoclavicular Space | 1st rib (below), clavicle (above), subclavius muscle | Subclavian vein, subclavian artery, brachial plexus |
| Subcoracoid/Retropectoralis Minor Space | Pectoralis minor tendon, coracoid process | Neurovascular bundle in extreme abduction |
3.3 Neural Anatomy
The lower trunk of the brachial plexus (C8, T1) is the structure most vulnerable to cervical rib compression. The T1 nerve root, which normally passes over the 1st rib to enter the lower trunk, is elevated by the cervical rib and subjected to tension and friction over its bony or fibrous shelf.
- The medial cord derives from the lower trunk - compression causes classic ulnar distribution symptoms (4th and 5th fingers, medial forearm)
- The T1 contribution to the median nerve may also be affected - weakness of thenar muscles
3.4 Vascular Anatomy
- The subclavian artery must arch over the 1st rib (or cervical rib). A cervical rib causes angulation/kinking of the artery, creating post-stenotic dilatation, turbulent flow, and thrombus formation.
- The subclavian vein lies anterior to the anterior scalene muscle and is more susceptible in the costoclavicular space than in the interscalene triangle.
3.5 Effect of a Cervical Rib on Local Anatomy
As noted by the THIEME Atlas: "In approximately 1% of the population, cervical ribs may narrow the interscalene space... In this condition the trunks of the brachial plexus that pass through the interscalene space along with the subclavian artery are compressed from behind and below."
A fibrous band frequently extends from the tip of a small cervical rib to rib I - this "cervical band" is not visible on X-ray but can be as clinically significant as a fully formed bony rib (Gray's Anatomy for Students).
4. INCIDENCE & EPIDEMIOLOGY
- Present in approximately 0.5-1% of the general population (Gray's Anatomy; THIEME Atlas)
- Bilateral in 50-80% of cases when present
- Symptomatic in only 10% of those who have it
- Female predominance: Neurogenic TOS is 3.5:1 female:male (Sabiston)
- Symptoms typically appear in the 2nd-4th decade
- In young women, symptoms may appear at puberty due to sagging of the shoulder girdle (S. Das)
5. ETIOLOGY
The primary cause is a congenital anomaly - the costal element of C7 fails to regress during embryonic development.
5.1 Predisposing and Precipitating Factors
| Factor | Mechanism |
|---|---|
| Congenital cervical rib (bony or fibrous) | Directly narrows interscalene triangle |
| Sagging shoulder girdle | Increases tension on brachial plexus over cervical rib - typical in young women at puberty (S. Das) |
| Muscular weakness of shoulder girdle | Allows descent of shoulder, increasing neurovascular traction |
| Neck trauma / whiplash | Triggers symptoms in a previously asymptomatic cervical rib |
| Repetitive overhead activities | Repeated trauma to already-compromised structures |
| Anomalous scalene muscles | Accessory scalene muscle bands can compress the plexus |
| Previous clavicle fracture | Callus reduces costoclavicular space |
| Drooping shoulder posture | Reduces all three thoracic outlet spaces simultaneously |
| Fibrous band | Even without bony rib, a fibromuscular band from C7 can produce identical symptoms |
The thoracic outlet syndrome also results from other causes: (i) scalenus anticus syndrome, (ii) costoclavicular syndrome, (iii) pectoralis minor syndrome, (iv) wide first thoracic rib - S. Das Manual on Clinical Surgery.
6. CLINICAL FEATURES
S. Das classifies the symptoms of cervical rib into three groups:
6.1 Local Symptoms
- Hard, fixed lump in the lower part of the posterior triangle of the neck (the rib itself, palpable on deep palpation)
- Local pain and tenderness in the supraclavicular fossa
- The rib may be palpable as a bony hardness in the supraclavicular region
6.2 Neurogenic Symptoms
Caused by pressure/irritation of the lower trunk of the brachial plexus (C8, T1):
Sensory:
- Tingling (paresthesia), numbness, and pain along the medial side of the forearm and hand (T1 dermatomal distribution)
- Classical ulnar distribution: medial forearm, ring and little fingers
- Often worse at night
Motor:
- Loss of power in the hand
- Wasting of the thenar and hypothenar eminences
- Wasting of the intrinsic hand muscles (interossei)
- In advanced cases: claw hand (due to intrinsic paralysis)
- Diminished sensation on the palmar aspect of the 5th digit
Vasomotor (sympathetic):
- Excessive sweating of the hand (hyperhidrosis)
- Circulatory impairment leading to digital gangrene in severe cases (S. Das)
6.3 Vascular Symptoms
- Pain in forearm worse with exercise (claudication-type)
- Hand colder than the opposite side
- Hand appears pale on elevation and becomes cyanotic in dependent position
- Numbness of the fingers
- Feeble or absent radial pulse on the affected side
- Subclavian artery aneurysm (post-stenotic dilatation)
- Digital emboli - black areas on fingertips (platelet emboli) - Gray's Anatomy for Students
- Subclavian vein thrombosis (Paget-Schrotter disease) causing arm swelling and pain
Harrison's (22E) adds:
- Arterial TOS: Blood pressure reduced in affected limb; signs of emboli in the hand; no neurologic signs
- Venous TOS: Swelling of the arm, pain, possible DVT
- Disputed TOS: 95% of all TOS diagnoses; chronic arm and shoulder pain of unclear cause; highly controversial management
7. CLASSIFICATION
7.1 By Type of Structure Compressed (Harrison's / Sabiston)
| Type | Structure Compressed | Prevalence | Features |
|---|---|---|---|
| Neurogenic TOS (nTOS) | Brachial plexus (lower trunk) | ~95% of true TOS | Motor/sensory deficits, pain, paresthesia |
| Venous TOS (vTOS) | Subclavian vein | ~3-4% | Arm swelling, cyanosis, DVT |
| Arterial TOS (aTOS) | Subclavian artery | ~1-2% | Ischemia, emboli, pale/cold hand |
| Disputed TOS | Unclear | ~95% of diagnosed cases | Chronic pain, no objective findings |
7.2 By Anatomy of the Cervical Rib (Gruber's Classification)
| Type | Description |
|---|---|
| Type I | Short rib - does not reach the 1st rib, ends freely |
| Type II | Longer rib - connected to 1st rib by a fibrous band (most common symptomatic type) |
| Type III | Rib reaches and articulates with 1st rib by a synchondrosis/joint |
| Type IV | Complete rib - fused with 1st rib, forms a complete bony arch |
7.3 By Clinical Presentation
- Asymptomatic (incidental finding - ~90% of cervical rib cases)
- Neurogenic (lower trunk brachial plexus compression)
- Vascular Arterial (subclavian artery compression)
- Vascular Venous (subclavian vein compression)
- Mixed (combined neurovascular)
8. INVESTIGATIONS / DIAGNOSIS
8.1 Clinical / Special Tests
| Test | Method | Positive Finding | Significance |
|---|---|---|---|
| Adson's Test | Patient inspires deeply, extends neck, rotates head to affected side; examiner palpates radial pulse | Reduction or obliteration of radial pulse | Tests interscalene triangle compression; positive in up to 20% of normals - low specificity |
| Costoclavicular / Halsted Test | Shoulders drawn backward and downward (military position) | Reduction of radial pulse, reproduction of symptoms | Tests costoclavicular space narrowing |
| Hyperabduction / Wright Test | Arm hyperabducted above head | Reduction of radial pulse | Tests subcoracoid compression |
| EAST / Roos Test | Arms held at 90° abduction + external rotation + 90° elbow flexion ("hold-up" position), patient opens and closes fists for 3 minutes | Reproduction of symptoms within 1-3 minutes | Best clinical test for nTOS (Current Surgical Therapy) |
| Elvey's Upper Limb Tension Test (ULTT) | Neural tension test | Reproduction of paresthesias | Used in physiotherapy assessment |
| Tinel's Test (supraclavicular) | Percussion over brachial plexus in supraclavicular fossa | Tingling in upper limb | Suggests brachial plexus irritation |
| Tenderness over anterior scalene | Deep palpation in low anterior neck | Tenderness | Common finding in nTOS |
Note from Current Surgical Therapy: "The EAST test is the most clinically beneficial - positive when symptoms are reproduced. Adson's maneuver can be positive in 20% of healthy individuals and should not be used alone."
8.2 Investigations
| Investigation | Findings |
|---|---|
| Plain X-ray (AP cervical spine / chest) | Demonstrates cervical rib; note - fibrous bands invisible |
| Duplex Ultrasonography | Assesses subclavian artery/vein compression, post-stenotic dilatation, thrombus |
| CT Angiography | Measures costoclavicular and interscalene spaces; evaluates arterial anatomy |
| Conventional Angiography | For arterial TOS prior to vascular reconstruction |
| Venography | Gold standard for venous TOS (Harrison's) |
| NCS/EMG | Confirms true neurogenic TOS; prolonged ulnar/median nerve conduction |
| MRI | Limited sensitivity, time-intensive; used in select atypical cases |
| Anterior scalene muscle block | Diagnostic: if symptoms relieved by local anaesthetic injection, strongly supports nTOS diagnosis |
9. TREATMENT METHODS
9.1 Conservative (Non-Surgical) Management
First-line treatment for neurogenic TOS and disputed TOS:
- Patient education - posture awareness, ergonomic modification, activity modification
- Physiotherapy (detailed in Section 11)
- NSAIDs - for pain and inflammation
- Muscle relaxants - if muscle spasm is significant
- Neuropathic analgesics - gabapentin/pregabalin for neuropathic pain
- Anterior scalene injection - lidocaine block (diagnostic + therapeutic); Botox injection for scalene spasticity
- Thrombolytics / anticoagulation - for venous TOS with DVT (Bailey & Love); for arterial TOS with thrombus
From Rosen's Emergency Medicine: "Brachial plexus involvement with minimal signs and symptoms often responds to conservative treatment with physiotherapy and shoulder girdle exercises."
9.2 Indications for Surgery
- Failure of conservative management (typically after 3-6 months)
- Progressive neurological symptoms (weakness, wasting)
- Prolonged ulnar or median nerve conduction velocities on NCS
- Arterial TOS (universally requires surgery - Current Surgical Therapy)
- Venous TOS with subclavian thrombosis
- Evidence of cervical rib with subclavian artery post-stenotic dilatation or thrombus
10. SURGICAL MANAGEMENT
10.1 Principles
The unifying goal of all surgical interventions is decompression of the thoracic outlet. This may involve:
- Excision of the cervical rib
- Resection of the 1st rib
- Division of fibromuscular bands
- Anterior scalenectomy (scalene muscle release)
- Vascular reconstruction (for arterial TOS)
10.2 Surgical Approaches
| Approach | Advantages | Best Used For |
|---|---|---|
| Transaxillary | Excellent cosmesis, wide exposure of interscalene triangle and costoclavicular space; preferred in ~99% of nTOS/vTOS | nTOS, vTOS |
| Supraclavicular | Direct visualization of brachial plexus, scalene muscles; allows scalenectomy and neurolysis | nTOS, especially with fibrous bands |
| Infraclavicular | Less commonly used; useful for vascular reconstruction | aTOS |
| Paraclavicular | Combined supra+infraclavicular; best exposure for vascular work | aTOS with arterial reconstruction |
| Robot-assisted / VATS | Minimally invasive; newer approach | Select cases |
10.3 Transaxillary Approach (Most Common)
From Current Surgical Therapy 14e:
- Patient positioned in lateral decubitus with arm in Machleder retractor at 90° abduction
- Incision in the axilla below the hairline
- Exposure of the interscalene triangle and costoclavicular space from a lateral direction
- First rib exposed widely; resection performed with visualization of brachial plexus and subclavian vessels
- Advantage: Excellent cosmesis - incision hidden in axilla
10.4 Supraclavicular Approach
- Allows direct visualization of the brachial plexus and scalene muscles
- Facilitates anterior scalenectomy (division of anterior scalene)
- Allows neurolysis of compressed neural elements
- Combined resection of cervical rib + first rib can be performed
- Fischer's Mastery of Surgery shows the "operative specimen following combined resection of cervical and first rib (left side)" via this approach
10.5 Arterial TOS - Special Considerations
From Current Surgical Therapy: "Unlike other forms of TOS, aTOS universally requires surgical intervention and frequently mandates surgery beyond thoracic outlet decompression... aTOS requires a tailored surgical approach based on the patient's specific anatomic abnormalities. This may include reconstruction of the axillosubclavian artery, thrombolysis, embolectomy, and/or distal bypass."
Gray's Anatomy for Students: "This patient underwent surgical excision of the cervical rib and had no further symptoms." (in a case of distal arterial embolization from cervical rib)
10.6 Post-Operative Management
- Early passive mobilization of the shoulder
- Progression to active ROM exercises
- Physiotherapy commenced early post-operatively (see below)
- Anticoagulation if venous/arterial TOS was treated surgically
- Monitoring for complications: pneumothorax, vascular injury, nerve injury, Horner's syndrome
11. PHYSIOTHERAPY MANAGEMENT
Based on: Jayant Joshi - Essentials of Orthopaedics & Applied Physiotherapy; Current Clinical Concepts (PMC11277273, 2024); Brigham & Women's Hospital TOS Standard of Care; BSI Physiotherapy Evidence-Based Protocols
Physiotherapy is the first-line treatment for neurogenic TOS and the cornerstone of both conservative and post-operative management.
11.1 Goals of Physiotherapy
- Decrease pain and neurological symptoms
- Correct posture (especially forward head and rounded shoulder posture)
- Restore range of motion (cervical, thoracic, shoulder)
- Strengthen scapular stabilizers and shoulder girdle muscles
- Improve neuromuscular control and scapular kinematics
- Normalize breathing patterns
- Functional rehabilitation and return to activity/sport
11.2 Physiotherapy Assessment
Postural Assessment:
- Forward head posture (increases tension on lower brachial plexus)
- Rounded/drooping shoulders (narrows all three thoracic outlet spaces)
- Thoracic kyphosis
- Scapular dyskinesia (winging, anterior tipping)
Special Tests Used by Physiotherapists:
- EAST/Roos Test (most reliable)
- Adson's Test
- Upper Limb Tension Test (ULTT1, ULTT3) - Elvey's test for neural mechanosensitivity
- Wright's Hyperabduction Test
- Costoclavicular Manoeuvre
- Tinel's Sign over brachial plexus
- Cervical Rotation Lateral Flexion Test (CRLT) - assesses first rib mobility
11.3 Phase 1 - Acute / Pain Management Phase
Objectives: Reduce pain and inflammation, protect neural and vascular structures
Modalities:
- Transcutaneous Electrical Nerve Stimulation (TENS) - pain modulation
- Ultrasound therapy - over scalene region (low-intensity, pulsed)
- Ice/heat application as appropriate
- Positional relief - arm supported in a sling or elevated to relieve neural tension
- Neural tension management - avoid provocative postures and movements
Education:
- Posture awareness and ergonomic advice
- Activity modification (avoid prolonged arm elevation, carrying heavy loads)
- Sleep positioning advice (avoid sleeping with arm overhead)
11.4 Phase 2 - Mobility and Manual Therapy Phase
Joint Mobilization (Maitland Grade I-III):
- First rib inferior glide mobilization - most important technique in TOS; reduces costoclavicular space compression, stretches anterior scalene
- Cervicothoracic junction mobilization - improves upper thoracic mobility
- Thoracic posterior-anterior mobilization - reduces thoracic kyphosis
- Lateral cervical glides - reduce scalene hypertonicity
- Glenohumeral joint mobilization - if ROM deficits exist
Soft Tissue Techniques:
- Scalene stretching (with caution - traction-based injury risk):
- Anterior scalene: ipsilateral rotation + contralateral side bend of cervical spine
- Middle scalene: cervical lateral flexion away
- Contract-relax / PNF techniques for scalene muscle inhibition
- Suboccipital release
- Pectoralis minor stretch - corner stretch, doorway stretch
- Levator scapulae and upper trapezius release
Neural Mobilization (Nerve Gliding):
- Median nerve slider (ULTT1 position)
- Ulnar nerve slider (ULTT2)
- Brachial plexus neural flossing - gentle sliders before tensioners
- Note: Stretching caution - TOS is often traction-based; positions that tension the plexus must be carefully graded
11.5 Phase 3 - Strengthening and Stabilization Phase
From the 2024 PMC review (evidence grade A): "Emphasis on middle and lower trapezius combined with serratus anterior to improve scapular control. Starting with short lever arm and a set/repetition scheme, athletes can complete without compensatory patterns."
Scapular Stabilizer Strengthening (Priority):
| Muscle Group | Exercises |
|---|---|
| Lower trapezius | Prone Y/T exercises, prone shoulder extension |
| Middle trapezius | Prone T-exercises, seated row (low row) |
| Serratus anterior | Wall push-up plus, shoulder protractions, serratus punches |
| Rhomboids | Scapular retraction exercises |
Cervical and Shoulder Stabilizers:
- Deep cervical flexor strengthening (chin tuck exercises against gravity)
- Cervical proprioception training
- Rotator cuff strengthening in neutral - avoid impingement positions
- Shoulder elevation with scapular control - progress from short to long lever
Postural Re-education:
- Chin tuck exercise (reduces forward head posture)
- Scapular retraction and depression exercises
- Wall angels (scapular control + thoracic extension)
- Brugger's postural relief position
11.6 Phase 4 - Functional Rehabilitation Phase
- Functional task training - sport or occupation-specific activities
- Gradual return to overhead activities with scapular control
- Breathing re-education - diaphragmatic breathing (reduces accessory muscle overuse - scalenes are accessory breathing muscles; chronic use elevates the first rib)
- Ergonomic workstation setup
- Home exercise program - to be continued indefinitely post-discharge (Brigham & Women's Standard of Care)
11.7 Post-Surgical Physiotherapy
Immediate Post-Op (0-2 weeks):
- Gentle pendulum exercises (Codman's)
- Passive ROM of shoulder
- Pain management (TENS, cryotherapy)
- Edema management if present
- Sling use as required
Early Rehabilitation (2-6 weeks):
- Active-assisted and active ROM exercises
- First rib mobilization (if access permits)
- Scapular setting exercises
- Neural gliding (gentle sliders)
Late Rehabilitation (6-12 weeks):
- Progressive strengthening of scapular stabilizers
- Functional activities
- Return to work/sport criteria
11.8 Blood Flow Restriction Training
Note: The 2024 PMC evidence review gives a SOR: C recommendation AGAINST blood flow restriction training in TOS patients: "Not recommended secondary to arterial and venous TOS and potential to progress to upper extremity deep venous thrombosis."
12. DIFFERENTIAL DIAGNOSIS
The following conditions must be excluded when diagnosing cervical rib/TOS (S. Das, Sabiston):
- Cervical spondylosis / cervical disc prolapse (radiculopathy)
- Carpal tunnel syndrome (median nerve compression at wrist)
- Cubital tunnel syndrome (ulnar nerve at elbow)
- Pancoast tumour (apical lung tumour with brachial plexus invasion + Horner's syndrome)
- Peripheral arterial disease of the upper limb
- Raynaud's phenomenon / disease
- Multiple sclerosis
- Syringomyelia
- Brachial neuritis (Parsonage-Turner syndrome)
- Subclavian steal syndrome
13. PROGNOSIS
- Conservative management: Most patients with nTOS who are conservatively managed return to work with significant symptom improvement (Brigham & Women's)
- Surgical management: Sabiston reports "surgery is beneficial in most patients with TOS, and long-term functional outcome of surgical treatment is good"
- Neurological deficits (wasting, weakness) often do not fully recover even after surgery - Harrison's: "The weakness and wasting of intrinsic hand muscles typically do not improve, but surgery halts the insidious progression of weakness"
- Arterial TOS has a good prognosis with appropriate surgical intervention
- Venous TOS has good outcomes with anticoagulation + surgical decompression

1. INTRODUCTION
Cervical rib is a congenital skeletal anomaly that may compress neurovascular structures at the thoracic outlet, producing Thoracic Outlet Syndrome (TOS). Though present in ~1% of the population, only 10% become symptomatic. Coote first surgically excised a cervical rib in 1861.
2. DEFINITION
A cervical rib is a supernumerary rib articulating with the 7th cervical vertebra (C7), representing failure of regression of the costal element of C7 during embryonic development.
"A cervical rib is an accessory rib articulating with vertebra CVII; the anterior end attaches to the superior border of the anterior aspect of rib I." - Gray's Anatomy for Students
A fibrous band often extends from the rib tip to rib I even when the bony rib is small - this is invisible on X-ray but equally symptomatic.
3. ANATOMY (Simplified)
Three anatomic corridors are vulnerable to compression:
| Space | Key Structures Passing Through |
|---|---|
| Interscalene Triangle | Subclavian artery + Brachial plexus |
| Costoclavicular Space | Subclavian vein + artery + Brachial plexus |
| Subcoracoid Space | Neurovascular bundle (in extreme abduction) |
A cervical rib elevates the lower trunk of the brachial plexus (C8, T1) and kinks the subclavian artery, producing neurogenic and vascular symptoms respectively.
4. ETIOLOGY
| Cause | Mechanism |
|---|---|
| Congenital cervical rib (bony/fibrous) | Directly narrows interscalene triangle |
| Sagging shoulder girdle (puberty in women) | Increases plexus traction over rib - S. Das |
| Neck trauma / whiplash | Triggers latent symptoms |
| Repetitive overhead activity | Repeated microtrauma |
| Anomalous scalene muscles | Additional compression |
| Previous clavicle fracture | Callus reduces costoclavicular space |
| Poor posture (forward head, rounded shoulders) | Narrows all three outlet spaces |
5. CLINICAL FEATURES
S. Das classifies symptoms into three groups:
(a) Local
- Hard, fixed lump in the posterior triangle of the neck
- Local pain and tenderness in the supraclavicular fossa
(b) Neurogenic (Lower trunk C8/T1 compression)
- Sensory: Tingling, numbness, pain along the medial forearm and hand (ulnar distribution)
- Motor: Weakness + wasting of thenar/hypothenar eminences and interossei; claw hand in advanced cases
- Vasomotor: Hyperhidrosis, digital gangrene (extreme)
(c) Vascular
- Forearm pain worse with exercise
- Hand colder than opposite side; pale on elevation, cyanotic when dependent
- Feeble or absent radial pulse
- Digital emboli (black fingertip areas) - subclavian artery thrombus
- Arm swelling + DVT (subclavian vein)
6. CLASSIFICATION
By Type of Structure Compressed (Harrison's / Sabiston)
| Type | Structure | Prevalence | Key Feature |
|---|---|---|---|
| Neurogenic TOS | Brachial plexus | ~95% | Motor/sensory deficits |
| Venous TOS | Subclavian vein | ~3-4% | Arm swelling, DVT |
| Arterial TOS | Subclavian artery | ~1-2% | Ischemia, emboli |
| Disputed TOS | Unclear | ~95% of diagnosed | Chronic pain, no objective signs |
By Anatomy of Rib (Gruber's Classification)
| Type | Description |
|---|---|
| Type I | Short rib - ends freely, no contact with 1st rib |
| Type II | Connected to 1st rib by fibrous band (most symptomatic) |
| Type III | Articulates with 1st rib via synchondrosis |
| Type IV | Complete bony rib - fused with 1st rib |
7. INVESTIGATIONS
| Test | Findings |
|---|---|
| Plain X-ray (AP cervical/chest) | Demonstrates bony rib; fibrous bands invisible |
| Duplex Ultrasound | Arterial/venous compression, thrombus, post-stenotic dilatation |
| CT Angiography | Measures costoclavicular/interscalene spaces; arterial anatomy |
| Venography | Gold standard for venous TOS |
| NCS/EMG | Confirms neurogenic TOS; prolonged conduction velocities |
| Anterior scalene block | Diagnostic + therapeutic for nTOS |
Clinical Provocation Tests
| Test | Technique | Positive |
|---|---|---|
| Adson's Test | Deep breath, neck extended, rotate to affected side | Radial pulse reduced |
| Costoclavicular (Halsted) Test | Shoulders drawn back + down (military position) | Pulse reduced + symptoms |
| EAST / Roos Test | Arms at 90° abduction + ER, open-close fists x 3 min | Symptoms reproduced within 1-3 min (most reliable - Current Surgical Therapy) |
| Wright Hyperabduction Test | Arm hyperabducted overhead | Pulse reduced |
| ULTT (Elvey) | Upper limb tension test | Neural paresthesias |
8. TREATMENT METHODS
8.1 Conservative Management (First-line for nTOS)
- Physiotherapy (see Section 10 - detailed)
- NSAIDs + muscle relaxants
- Neuropathic agents (gabapentin/pregabalin)
- Anterior scalene lidocaine block / Botox injection
- Anticoagulation for venous TOS with DVT
- Thrombolytics for arterial TOS with thrombus
"Brachial plexus involvement with minimal signs and symptoms often responds to conservative treatment with physiotherapy and shoulder girdle exercises." - Rosen's Emergency Medicine
9. SURGICAL MANAGEMENT
9.1 Indications
- Failure of conservative management (3-6 months)
- Progressive neurological symptoms (wasting, weakness)
- Prolonged NCS conduction velocities
- Arterial TOS (always requires surgery)
- Venous TOS with subclavian thrombosis
9.2 Surgical Goals
Decompression of the thoracic outlet by:
- Excision of the cervical rib
- Resection of the 1st rib
- Division of fibromuscular bands
- Anterior scalenectomy
- Vascular reconstruction (arterial TOS)
9.3 Surgical Approaches
| Approach | Best For | Key Advantage |
|---|---|---|
| Transaxillary (preferred ~99% of nTOS/vTOS) | nTOS, vTOS | Excellent cosmesis; wide exposure of both key spaces |
| Supraclavicular | nTOS with fibrous bands | Direct brachial plexus visualization; allows neurolysis + scalenectomy |
| Paraclavicular (supra + infraclavicular) | aTOS | Best exposure for vascular reconstruction |
| Infraclavicular | aTOS - vascular work | Arterial access |
| Robot-assisted / VATS | Select cases | Minimally invasive |
9.4 Transaxillary Approach (Most Common)
From Current Surgical Therapy 14e:
- Patient in lateral decubitus, arm suspended in Machleder retractor at 90° abduction
- Axillary incision (hidden in axilla - excellent cosmesis)
- First rib exposed from a lateral direction
- Wide visualization of brachial plexus + subclavian vessels
- Cervical rib + first rib resected as needed
9.5 Supraclavicular Approach
- Direct approach for scalenectomy + neurolysis
- Preferred when fibrous bands are the primary compressor
- Allows combined cervical + first rib resection
- Visualizes and protects brachial plexus directly
9.6 Arterial TOS - Special Considerations
"Unlike other forms of TOS, aTOS universally requires surgical intervention and frequently mandates surgery beyond thoracic outlet decompression... This may include reconstruction of the axillosubclavian artery, thrombolysis, embolectomy, and/or distal bypass." - Current Surgical Therapy 14e
9.7 Post-Operative Management
- Early passive shoulder mobilization
- Physiotherapy commenced early (Phase 1 protocol)
- Anticoagulation where indicated
- Monitor for: pneumothorax, vascular injury, nerve injury, Horner's syndrome
9.8 Prognosis After Surgery
- Surgery halts neurological progression but wasting/weakness often does not recover - Harrison's 22E
- Arterial and venous TOS have good prognosis post-decompression
- Sabiston: "Surgery is beneficial in most patients with TOS, and long-term functional outcome is good"
10. PHYSIOTHERAPY MANAGEMENT
Based on: Jayant Joshi - Essentials of Orthopaedics & Applied Physiotherapy | Current Clinical Concepts in TOS Rehabilitation (PMC11277273, 2024) | Brigham & Women's Hospital TOS Standard of Care
Physiotherapy is the first-line treatment for neurogenic TOS and forms the backbone of both conservative and post-operative management.
10.1 Goals of Physiotherapy
- Decrease pain and neurological symptoms
- Correct posture - forward head and rounded shoulder
- Restore cervical, thoracic, and shoulder ROM
- Strengthen scapular stabilizers and shoulder girdle
- Improve neuromuscular control and scapular kinematics
- Normalize breathing patterns
- Functional rehabilitation and return to work/sport
10.2 Physiotherapy Assessment
Postural Assessment:
- Forward head posture (increases lower brachial plexus tension)
- Drooping/rounded shoulders (narrows all three outlet spaces)
- Thoracic kyphosis
- Scapular dyskinesia (winging, anterior tipping)
Special Tests:
- EAST/Roos Test (most reliable)
- Adson's Test
- Upper Limb Tension Tests (ULTT1, ULTT3) - Elvey's neural tension tests
- Wright's Hyperabduction Test
- Costoclavicular Manoeuvre
- Cervical Rotation Lateral Flexion Test (CRLT) - assesses first rib mobility
- Tinel's Sign over brachial plexus (supraclavicular)
10.3 Phase 1 - Acute / Pain Management
Objectives: Reduce pain and inflammation, protect neural and vascular structures
Electrotherapy & Modalities:
- TENS - pain modulation
- Pulsed ultrasound over scalene region (low intensity)
- Cryotherapy / Heat as appropriate
- Interferential therapy (IFT) for deeper pain relief
Positioning & Protection:
- Arm supported in sling or elevated to relieve neural tension
- Avoid provocative postures (overhead activities, arm across body)
- Sleep positioning advice - avoid sleeping with arm overhead
Patient Education:
- Posture awareness and ergonomic workstation setup
- Activity modification
- Understanding the condition and expected recovery timeline
10.4 Phase 2 - Mobility and Manual Therapy
Joint Mobilization (Maitland Grade I-III):
| Technique | Target | Rationale |
|---|---|---|
| Inferior first rib mobilization | First rib | Increases costoclavicular space; stretches anterior scalene - most important technique |
| Cervicothoracic junction mobilization | C7-T1 | Improves upper thoracic mobility |
| Thoracic PA mobilization | Mid-thoracic | Reduces kyphosis, improves posture |
| Lateral cervical glides | Cervical spine | Reduces scalene hypertonicity |
| Glenohumeral mobilization | GHJ | If ROM deficits exist; avoid costoclavicular compression positions |
| Posterior GHJ capsule mobilization | Posterior capsule | Improves posterior capsule mobility in overhead athletes |
Soft Tissue Techniques:
- Anterior scalene stretch: Ipsilateral cervical rotation + contralateral side bend
- Middle scalene stretch: Cervical lateral flexion away from affected side
- Pectoralis minor stretch: Corner/doorway stretch
- Upper trapezius + levator scapulae release
- Suboccipital release
- Contract-relax (PNF) for scalene inhibition
Neural Mobilization (Nerve Gliding):
- Median nerve slider (ULTT1 position)
- Ulnar nerve slider (ULTT2/ULTT3)
- Brachial plexus neural flossing - sliders before tensioners
- Caution: TOS is often traction-based - grade neural mobilization carefully to avoid symptom aggravation
10.5 Phase 3 - Strengthening and Stabilization
From 2024 evidence review (SOR: A): "Emphasis on middle and lower trapezius combined with serratus anterior to improve scapular control. Starting with short lever arm and a set/repetition scheme that athletes can complete without compensatory patterns."
Scapular Stabilizer Strengthening (Priority Muscles):
| Muscle Group | Exercises |
|---|---|
| Lower Trapezius | Prone Y-exercises, prone shoulder extension |
| Middle Trapezius | Prone T-exercises, seated low row |
| Serratus Anterior | Wall push-up plus, serratus punches, shoulder protraction |
| Rhomboids | Scapular retraction exercises |
Cervical and Shoulder Stabilizers:
- Deep cervical flexor strengthening - chin tuck exercises (progressive)
- Cervical proprioception training
- Rotator cuff strengthening in neutral range (avoid impingement positions)
- Progressive shoulder elevation with scapular control
Postural Re-education:
- Chin tuck exercise - corrects forward head posture
- Wall angels - scapular control + thoracic extension
- Brugger's postural relief position
- Scapular retraction and depression exercises
Breathing Re-education:
- Diaphragmatic breathing technique - reduces scalene overuse as accessory breathing muscles
- Scalenes, when chronically overloaded with breathing, elevate the first rib and worsen compression
10.6 Phase 4 - Functional Rehabilitation
- Functional task training - occupation/sport-specific progressive loading
- Gradual return to overhead activities with maintained scapular control
- Ergonomic workstation assessment and setup
- Home exercise program - continued indefinitely post-discharge (Brigham & Women's Standard of Care)
- Return to sport criteria - full ROM, symmetrical strength, no symptom reproduction on EAST test
10.7 Post-Surgical Physiotherapy Protocol
| Phase | Timeframe | Focus |
|---|---|---|
| Immediate Post-Op | 0-2 weeks | Codman's pendulum exercises, passive ROM, TENS, cryotherapy, edema management |
| Early Rehab | 2-6 weeks | Active-assisted + active ROM, scapular setting exercises, gentle neural gliders, first rib mobilization |
| Late Rehab | 6-12 weeks | Progressive scapular strengthening, functional activities, return to work/sport |
| Discharge | 12+ weeks | Independent HEP, ergonomic advice, self-management strategies |
10.8 Special Considerations
Blood Flow Restriction Training: NOT recommended in TOS patients (SOR: C) - risk of progression to upper extremity DVT in arterial and venous TOS cases (PMC11277273, 2024).
Stretching Caution: TOS is frequently a traction-based injury. Stretching positions that load the brachial plexus in tension must be carefully graded. Sliders before tensioners; never force through reproduction of paresthesias.
Bilateral Involvement: Since cervical ribs are bilateral in 50-80% of cases, assess and treat both sides even if only one is symptomatic.
