Study Notes
- The shoulder joint is very mobile due to articulating surfaces and scapulothoracic movement.
- Ligaments in the shoulder joint are complex and contribute to stability.
- Ligaments can become stretched or torn, limiting range of motion or causing dislocation.
- The superior ligament is stretched with backward rotation or anterior translation of the humerus.
- The inferior ligament has three parts and allows for full range of motion.
- Overstretching of ligaments can lead to subluxation or dislocation.
- Regeneration of ligaments after complete tear is not always successful.
- Stability factors are important to prevent pathology.
- Joint capsule in the shoulder is larger than in other joints.
- Mobility in the shoulder can lead to compensatory movements.
