What Is Joint Instability?
Instability happens when tissues — such as muscles, ligaments, and bones — weaken. Once they are weak, they no longer hold the bones of the joint in proper place.
Joints are flexible, allowing for movement. However, they also must be stable and strong.
Strong ligaments hold the bones of joints in place while the joints are in motion and at rest. Muscles and tendons hold the bones of the joints in place most often when moving.
Types of joint instability
Common cases of joint instability occur in the:
- Ankle
- Big toe
- Elbow
- Hip
- Knee
- Neck
- Shoulder
- Thumb
What causes instability?
Risk factors that may cause joint instability include:
- Injury — such as a fall — can cause a dislocation of a joint or stretch or tear the ligaments.
- Overuse or repeating a movement over time can cause instability. Swimming, for example, can lead to shoulder instability.
- Multidirectional instability — known as being “double jointed” — happens to some people who are born with looser joints than most others.
