When the scapula moves along the chest wall during the scapular linkage movement, there is sometimes a rubbing, popping or vibrating sound and a feeling of soreness and discomfort. Doctors call this popping scapula syndrome. When this occurs, the soft tissue between the scapula and the chest wall becomes thickened, irritated, and even inflamed. Causes of popping scapula: abnormal development of the scapula, soft tissue abnormalities (normal variation, or benign and malignant tumors), muscle atrophy resulting in popping scapula more factors, including developmental and acquired factors, among which there are mainly the following categories: 1, developmental factors Mainly the scapula is more anteriorly flexed in the upper angle. 2.Abnormal hyperplasia The abnormal fibrocartilage nodules in the superior intra-scapular horn are the most common. 3.Bursitis Chronic inflammatory proliferation and hypertrophy of the bursa between the scapula and the chest wall 4.Tumor Chondroosteoma between the scapula and the scapular chest wall, where the chondroosteoma is often flattened due to pressure. 5.Occasionally, there may be abnormal bone fiber connection between the inner corner of the scapula and the cervical vertebrae, rib tumor or other developmental morphological abnormalities, etc. 6.Powered scapular instability due to imbalance in the strength of the muscles around the shoulder. What conditions increase the risk of developing a popping scapula? Physical confrontation, hedging sports; poor physical condition (lack of muscle strength and flexibility); inadequate warm-up before exercise; muscle strength imbalance or muscle atrophy in the muscles around the scapula; previous scapular fracture or rib fracture How to treat the popping scapula? Conservative treatment: Most patients can be treated conservatively, especially if the popping scapula is caused by a soft tissue problem. This includes the use of non-steroidal anti-inflammatory drugs to reduce inflammation and pain, such as aspirin and ibuprofen. Rest and ice can reduce the inflammatory response and pain. Physical and rehabilitative therapy including stretching and strength exercises, and local injections of steroids such as cortisone for bursitis can be effective in reducing the inflammatory response. Surgery: Surgery is considered for patients who have not responded to conservative treatment for more than 6 months. If it is due to a bony abnormality, a minimally invasive arthroscopic procedure (i.e., a hole is made in the back of the shoulder and a miniature camera is placed and operated through a monitor) can be used to remove the bony abnormality or inflamed bursal tissue.
