Study Notes
Glenohumeral Joint
- Joint Type: Synovial, ball and socket
- Articulating Surfaces:
- Humeral head: Medial, slightly posterior, and superior.
- Glenoid fossa: Lateral, forward, and superior; pear-shaped, narrow superiorly, wider inferiorly.
- Capsular Strength/Coaptation: Weak and lax, especially inferiorly (axillary pouch).
- Ligaments:
- Superior/Middle/Inferior Glenohumeral Ligaments: Anterior thickening/reinforcement, limits external rotation, provides anterior stability. Middle ligament limits lateral rotation up to 90 degrees abduction. The inferior is the thickest and prevents anterior subluxation/dislocation.
- Coracohumeral Ligament: Strengthens superior capsule, resists gravity.
- Transverse Humeral Ligament: Holds long biceps tendon in groove. Rupture = unstable biceps tendon.
- Extras:
- Dynamic ligaments: Rotator cuff tendons blend with joint capsule fibers.
- Glenoid labrum: Deepens glenoid cavity for better articulation.
Acromioclavicular Joint
- Joint Type: Synovial, modified gliding
- Articulating Surfaces: Medial surface of acromion, incomplete articular disc, acromion facet of clavicle. Compression force = clavicle overrise acromion—AC separation.
- Capsular Strength/Coaptation: Weak and lax.
- Ligaments:
- Superior/Inferior Acromioclavicular Ligaments: Prevents AC separation.
- Coracoclavicular Complex:
- Trapezoid Ligament (horizontal, lateral): Limits excessive lateral movements.
- Conoid Ligament (vertical, medial): Limits excessive superior movement and scapuloclavicular angle widening.
- Extras: Incomplete intra-articular disc, dangles from superior part of inside the synovial joint capsule.
Sternoclavicular Joint
- Joint Type: Synovial, modified gliding
- Articulating Surfaces: Clavicular notch of manubrium, sternal end of clavicle.
- Capsular Strength/Coaptation: Weak and lax, inferiorly.
- Ligament:
- Anterior/Posterior Sternoclavicular Ligaments: Stabilizing.
- Interclavicular Ligament: Limits excessive medial movement.
- Costoclavicular Ligament: Limits elevation with medial movement and elevation with lateral movement.
- Extras: Complete intra-articular disc to prevent medial separation.
Glenohumeral Joint Biomechanics
- Osteokinematics: 3 degrees of freedom (flexion/extension, abduction/adduction, external/internal rotation).
- Arthrokinematics: Humeral head (convex), glenoid fossa (concave).
- Resting Position: 55–70 degrees abduction, 30 degrees horizontal adduction.
- Closed-Packed Position: Full abduction and external rotation.
- Capsular Pattern of Restriction: External rotation > Abduction > Internal rotation.
- ROM & End Feel:
- Flexion: 180°, firm.
- Extension: 60°, firm.
- External Rotation: 90°, firm.
- Internal Rotation: 70°, firm.
- Abduction: 180°, firm/hard.
- Horizontal Abduction: 45°, firm.
- Horizontal Adduction: 135°, firm/soft.
Acromioclavicular Joint Biomechanics
- Osteokinematics: 3 degrees of freedom (elevation/depression, protraction/retraction, anterior/posterior rotation).
- Arthrokinematics: Acromion (concave), acromial end of clavicle (convex).
- Resting Position: Arm by side.
- Closed Packed Position: Arm abducted to 90 degrees.
- Capsular Pattern of Restriction: Full elevation with associated pain.
- ROM & End Feel: Elevation/Depression: 30°, Protraction/Retraction: 50°, Rotation: 50°, all with capsular firm end feel.
Sternoclavicular Joint Biomechanics
- Osteokinematics: 3 degrees of freedom (elevation/depression, protraction/retraction, anterior/posterior rotation).
- Arthrokinematics: Clavicular notch of manubrium (ant/post-convex, sup/inf-concave), sternal end of clavicle (ant/post-concave, sup/inf-convex).
- Resting Position: Arm by side.
- Closed Packed Position: Arm maximally elevated.
- Capsular Pattern of Restriction: Full elevation with associated pain.
- ROM & End Feel: Elevation/Depression: 15°, Protraction/Retraction: 10°, Rotation: 50°, all with capsular firm end feel.
Joint Mobilization: Sternoclavicular Joint
- Inferior/Superior Facets: Convex on concave (superior roll, inferior glide).
- Anterior/Posterior Facets: Concave on convex (posterior roll, posterior glide).
Scapular Plane & Scaption
- Scapular Plane: Requires 20 degrees of horizontal adduction.
- Scaption: Horizontal abduction in frontal plane, good for muscle balance of all rotator cuff muscles.
Shoulder Stabilization
- General: Shoulder capsule is relatively lax; muscles provide active stabilization. Some passive stability if joint is correctly oriented.
- Passive Stability (neutral): Glenoid fossa lip (superior, anterior, lateral), superior glenohumeral ligament, coracohumeral ligament. This position tightens the superior joint capsule and coracohumeral ligament, pulling humeral head against glenoid cavity.
- Active Stability (raised arm): Rotator cuff maintains dynamic congruency and stability.
- Compromised Stability: Excess Thoracic Kyphosis (downward scapular rotation) → lax superior capsule and coracoacromial ligaments; rotator cuff overworks to provide active stability, possible impingement syndrome. Muscle paresis (partial paralysis) → forward scapular rotation → possible inferior dislocation or subluxation (neurological injury).
GH Joint Capsule & Movement
- GH joint capsule fibers face anteriorly and medially. Abduction twists the capsule, which increases tension and pulls the humeral head into the glenoid cavity. Medial fibers become taut further aiding abduction. Capsule pulls the humerus into external rotation to prevent greater tubercle collision with acromial arch. Capsule important for lateral rotation.
Force Couples
- Deltoid & Rotator Cuff: Deltoid pulls up and out, rotator cuff pulls down and in for humeral head centration.
- Serratus Anterior & Upper Trapezius: Allow scapular upward rotation during arm movements.
- Long Head of Biceps Tendon: During lateral rotation, acts as a pulley depressing the humeral head for centration.
Abduction Biomechanics
- Scapulohumeral Rhythm:
- Phase 1 (0–30°): Scapular setting, no scapulohumeral rhythm, minimal scapular movement, 0–5° clavicular elevation.
- Phase 2 (30–90°): Next 60° elevation, 2:1 scapulohumeral rhythm, scapula starts rotating (20°), clavicle elevates further (15°).
- Phase 3 (90–180°): Last 90° elevation, 2:1 ratio, clavicle elevates, rotates posteriorly, humerus laterally rotates 90° to clear acromial arch. Requires thoracic spine movement too.
- Reverse Scapulohumeral Rhythm: Scapula moves more than humerus, often indicative of frozen shoulder, especially visible in first 30 degrees.
- Clavicle – SC & AC – Movement:
- SC joint: Clavicle moves on manubrium, sternal clavicular facet: 'apple-core' shape (ant/post = concave, sup/inf = convex). Concave/convex movements = same direction of glide. Convex/concave movements = opposite direction of glide.
- Axial Skeleton Movement: Thorax function critical, hyperkyphosis limits abduction.
Observation
- Step Deformity: Distal clavicle, AC separation indication.
- Sulcus Sign: Sagging/flattening below acromion, dislocation/deltoid paralysis indicator.
- Mal-alignment of clavicle: Often due to fractures.
- Scapular Winging: Medial border moves away from posterior chest wall (not spine). Dynamic (serratus anterior injury) or static (structural deformity).
- Scapular Tilting: Superior/inferior angles tilt away from chest wall, weakness/instability or pec minor tightness.
- Painful Arc: 0–45° painless, 60–120° pain (impingement). Last 10–20° pain (impingement, potentially AC/SC joint involvement).
- Apley's Scratch: Quick function scan, not an orthopedic test.
