Capsular Pattern: Glenohumeral Joint
SLAM
Shoulder: Lateral Rotation > Abduction > Medial Rotation
Loss of movement
Resting (loose pack) Positon: GHJ
Thoracic Outlet Syndrome
Description & Border & Contains
The area along the brachial plexus between the nerve roots & lower border of the axilla
Borders:
- ANTERIOR: clavicle, coracoid process, pec minor
- POSTERIOR: Upper Fibers of Traps (UFT), scapula
- MEDIAL: scalene mm & R1(first rib - behind clavicle)
- LATERAL: axilla
Contains:
- Brachial Plexus
- Subclavian artery
- Subclavian vein
Starts outside medial border (infront of scalenes) & passes infront of rib 1 && then joins the other outlet
Thoracic Outlet Syndrome
Description & Types
A term used to describe a group of signs & symptoms resulting from compression of nerves or vascular structures in the thoracic outlet
Diagnosis of exclusion - tends to be overdiagnosed
Types:
1. Neurogenic (True TOS)
2. Nonspecific “symptomatic” neurogenic
3. Vascular syndromes - arterial
4. Vascular syndromes - venous
Neurogenic (true TOS)
2
Patient presents with an anatomical anomaly compressing the brachial plexus (cervical rib - extra, or elongated C7 TP)
True TOS is rare
Nonspecfic “Symptomatic” Neurogenic
4
Most common
Vascular - arterial
3
Vascular - venous
2
TOS S/S
3 Types (4 + 5 + 2)
Neurogenic
1. Paresthesia
2. Numbness
3. Weak grip strength (?atrophy of thenar)
4. Loss of manual dexterity & precision movements in hand
Vascular - Aterial:
1. Cool skin
2. Pale extremity (BF interruptions)
3. Dimished or absent pulse
4. Rapid fatigue of limb
5. Lower BP on the affected side
Vascular - Venous:
1. Painful swelling in arm
2. Mottled, bluish discolouration

Scalenus Anterior Syndrome
- Site of compression: Interscalene triangle - b/t the scalenus anterior & medius (supraclavicular)
Costoclavicular Syndrome
- Site of compression: Costoclavicular space - b/t the clavicle & first rib (subclavicular)
Hyperabduction Syndrome
- Site of compression: Axillary interval: Under the coracoid process & behind the pec minor (infraclavicular)
Cervical Rib Syndrome
Special Tests:
Adson Manuever
Costoclavicular Syndrome (Military Brace) Test
Halstead Manuever
Wright Test
Allen Test
All tests palpate RADIAL pulse in different postures
(+) = if radial pulse dissapears
Aterial type TOS
Special Test: Roos Test (Elevated Arm Stress Test)
Procedure:
PT open & closes fists with shoulder (horizontal abduction) & elbow at 90 degrees for 3 minutes
(+) = inability to hold position for 3 mins
- Ischemic pain - arterial
- Heaviness/weakness = arterial
- S/S of neurological weakness - ex. numbness & tingling
Special Test: Shoulder Girdle Passive Elevation (Cyriax Release Test)
Procedure:
- Pt crosses arms & PT lifts elbows up - elevation
(+) = relieves neurological S/S
- Skin colour changes / temp - arterial
- Pulse becomes stronger
- Less cyanotic - venous
Cyriax = switch arm positions: pt has elbows @ 90 & pronated & PT lifts the arms this way
Cross Body (Horizontal) Adduction Test
Shoulder Separation
(+) = if the maneuver successfully reproduces the patient’s symptoms of pain localized over the AC joint
Shoulder Separation
Definition & Etiology
Trauma to the ligaments holding the acromion and clavicle togeter causing separation b/t the 2 joint surfaces (subluxation or dislocation)
Etiology
1. Downward force on the acromion
2. Directly falling on or hitting the acromion
3. Falling on outstretched hand or falling on elbow
Shoulder Separation: S/S
(3)
Shoulder Separation: Special Test
1
Cross Body (Horizontal) Adduction Test
Shoulder Separation: Radiology
1
Stress-view X-Ray:
- Patient hold weight onto each arm - longitudinal traction
- Places an inferior pressure on ACJ
Shoulder Separation: Rockword Classification
3
Type I: Sprain
- Capsule is intact
- No separation or excessive spacing is seen
Type II: Subluxation
- Increased ACJ spacing
Type III: Dislocation
- Increased ACJ & costoclavicular space - completely dislocates
- Joint surfaces not in contact with each
Glenohumeral Joint Instability: Classifications
4
Shoulder Dislocation
3
Separation of the humerus from the scapula
Most commonly dislocated joint in the body - very mobile - many degrees of freedom
Anterior dislocation is the most common = orthopedic population
Inferior dislocation = stroke population
