When the shoulder makes a popping sound, it is called “shoulder crepitus.” Shoulder crepitus is when the shoulder joint makes a clicking or popping sound when it’s in motion.
This condition can also occur in the knee and finger joints. This condition can cause pain in the joints.
If you are experiencing pain or hear a popping or clicking sound in your shoulder, then schedule a consultation with our expert orthopedic surgeons at OrthoNeuro.
Anatomy of the Shoulder Joint
The shoulder is a complex joint in the body that is complete with muscles, ligaments, cartilage, and tendons all working together to allow a wide range of flexibility and motion in the arm.
The shoulder is a ball and socket joint and can be easily injured because of its many components.
In the shoulder, the humerus bone (upper arm bone) connects to the socket of the scapula (shoulder blade) and goes from the back to your clavicle (collarbone).
The labrum (a soft cartilage cup) lines the socket and helps to hold the arm in place.
What Are the Causes of Clicking Noises in the Shoulder?
The clicking sound that is heard when a shoulder “pops” is from the muscles and tendons moving over the bone.
Usually, when this sound occurs, it is a sign that one of the tendons or muscles in the shoulder has been damaged.
This condition is usually caused by sports injuries and general overuse of the joint.
