List as many features as you can that facilitate the mobilityof the glenohumeral joint. Think about the shape of the capsule,shape of the joint surfaces, ligaments, structures around thejoint, accessory joints, and bones that contribute to full range ofmovement around the shoulder. Consider how these affect themobility of the shoulder joint and shoulder complex, and how theymay be a tradeoff for loss of stability.
Factors increasing mobility of the joint:
- Bones:
- Capsule:
- Synovial membrane & bursae:
- Muscles:
- Accessory joints:
- Scapulo-humoral rhythm:
Factors maintaining stability of the joint:
- Labrum:
- Rotator cuff:
- Ligaments:
- Tendons:
When you talk about each factor, please focus on its role ineither mobility and stability. For example, you don't have todescribe the attachment of the capsule and the ligaments, but whatis specific in the capsule to increase mobility, and how eachligament supports and stabilizes the joint. Another example aboutthe rotator cuff muscles, you don't have to describe each muscle indetail, but how they are the most important factor in maintainingthe stability of the joint.
