Names
- Superior Shoulder Suspensory Ring
- Shoulder Suspensory Complex
- Superior Shoulder Suspensory Complex (SSSC)
- Superior Shoulder Girdle Ring
- Superior Shoulder Girdle Complex
- Osseoligamentous ring of the shoulder
- Shoulder suspensory ring
- Scapuloclavicular suspensory complex
- Upper shoulder girdle suspensory system
General Description
- Important structure composed of a ring of bone and soft tissues at the superior aspect of the shoulder
- Suspend the upper extremity from the axial skeleton while maintaining stability and alignment of the shoulder girdle
- Double disruption leads to instability of the construct and usually requires operative treatment
- Triple disruption of the SSSC is extremely rare, encountered in high-energy trauma
Function
- Suspends the upper extremity from the axial skeleton via the clavicle
- Maintains structural integrity of the shoulder girdle
- Provides a stable platform for glenohumeral motion
- Transmits forces between the upper limb and the trunk
- Maintains alignment of the scapula and clavicle
- Resists vertical and rotational displacement of the shoulder girdle
- Distributes mechanical load across bony and ligamentous components
- Protects against instability during high-demand shoulder movements
Anatomic Contents[6]
- Glenoid Process
- Coracoid Process
- Coracoclavicular Ligament
- Distal end of the Clavicle
- Acromioclavicular Joint
- Coracoacromial Ligament
- Acromial Process
Clinical Significance
- Single Disruption: stable
- Double disruption: compromise ring, instability of shoulder girlde, surgical
- Triple Disruption: rare
Pathology
- Distal clavicle fracture
- Acromioclavicular (AC) joint separation or dislocation
- Coracoclavicular ligament rupture (conoid and/or trapezoid)
- Avulsion fracture of the coracoid at the CC ligament attachment
- Scapula Fracture including acromion, coracoid process, glenoid, scapular spine
