Under normal circumstances, both shoulders should be of equal width and height, and there is no obvious protrusion of the upper angle of the scapula. If there is protrusion, it is abnormal, and it is often caused by dislocation of the shoulder joint, muscle injury and scoliosis.
1. Shoulder dislocation: if the patient’s shoulder is traumatized and there is local swelling and pain in the joint, there may be shoulder dislocation, and the upper angle of the scapula may be protruding at this time.
2. Muscle injury: if the serratus anterior and trapezius muscles are damaged, the muscle constraints on the scapula will be reduced, resulting in the protrusion of the upper angle of the scapula.
3. Scoliosis: When there is scoliosis, the patient may also have unilateral protrusion of the upper angle of the scapula.
There are other reasons for scapula protrusion. If scapula protrusion is accompanied by other uncomfortable symptoms, it is recommended that the patient consult a doctor in time for treatment under the guidance of the doctor.
