Protruding ribs may be caused by chicken breast, rib ectropion, rib tumors, or simple developmental deformities of the ribs. Patients who find protruding ribs should go to the hospital in time to find out the cause of the disease and improve the symptoms. Chicken breast usually refers to the appearance of chicken or pigeon breast due to the depression of adjacent ribs and rib cartilage. Chicken breast is caused by calcium deficiency during development, so calcium supplements should be prescribed. Rib ectropion is the outward protrusion of the ribs below the thorax when the child is lying down, and can be greatly improved with aggressive treatment at a young age. Tumors of the ribs usually appear as localized swelling and protrusion on one side of the rib cage. Rib tumors may be benign tumors, such as benign osteochondroma. However, rib tumors are more likely to be malignant, such as malignant myeloma and chondrosarcoma. If it is a simple malformation of the rib development, it should not be a big problem, it will just affect the appearance.
