Where is the 11th rib located
Since the first rib is hidden behind the clavicle, the second rib is the highest rib that can be identified by palpation. Thus, the sternal angle and second rib are important landmarks for the identification and counting of the lower ribs. Ribs 3—7 attach to the sternal body. The inferior tip of the sternum is the xiphoid process. This small structure is cartilaginous early in life, but gradually becomes ossified starting during middle age.
Each rib is a curved, flattened bone that contributes to the wall of the thorax. The ribs articulate posteriorly with the T1—T12 thoracic vertebrae, and most attach anteriorly via their costal cartilages to the sternum.
There are 12 pairs of ribs. The ribs are numbered 1—12 in accordance with the thoracic vertebrae. The bony ribs do not extend anteriorly completely around to the sternum. It seems to be reported most often by middle-aged women, though cases have occurred in men, women, and children of all ages.
The exact cause of slipping rib syndrome isn't known, but common risk factors are overuse or rib trauma. Most injuries to the chest wall and rib cage are treated the same way.
Unlike with other bones of the body, such as an arm or leg, the chest cannot be immobilized if a bone is broken. Similarly, if a person has experienced trauma to the muscles or ligaments in the chest, there is not much that can be done to reduce movement—as the chest needs to move at least enough to expand as a person breathes.
The treatment for soft tissue injury and fractures is, therefore, the same and mostly focused on controlling pain and any exacerbating factors such as a cough.
Given adequate time and supportive care including pain management , these injuries usually heal on their own. The healing period can be very uncomfortable, however, and maybe prolonged if the chest is further irritated or reinjured. A doctor may suspect a person has the condition after ruling out other causes for their symptoms, such as a rib fracture, esophagitis, or pleuritic chest pain.
The gold standard for diagnosing the condition is a simple hooking maneuver, which can be performer in the office, that can help determine if the lower ribs are hypermobile.
Treatment depends on the severity of the associated pain. If a person with slipping rib syndrome has continued pain that is not well controlled with over-the-counter pain relievers, temporary activity limitations, and use of icepacks, a doctor may prescribe nerve blocks. While the condition can range from a mild annoyance to a painful interruption to one's activities, slipping rib syndrome does not put a person at greater risk for injury or a more serious condition involving the chest wall or rib cage.
With proper management, awareness of the nature of the condition, and reassurance, most people who experience it do not suffer any complications.

National Library of Medicine. Bruised rib care. Updated June February British Journal of Surgery. DOI: Heinz G. Slipping Rib Syndrome. Journal of Ultrasound in Medicine. Each true rib connects to its own strip of costal cartilage, which in turn connects to the sternum. Ribs are called the false ribs. Ribs 8, 9, and 10 do connect to costal cartilage, but the costal cartilage of each of these ribs connects to the costal cartilage of the rib above it, rather than directly to the sternum.
Ribs 11 and 12 do not have any costal cartilage connected to them at all, and in addition to being grouped in the false ribs, these two are also called floating ribs , to reflect that fact.
The sternum has three parts. The manubrium , at the superior end of the sternum, and wider than the rest of the bone, provides articulation points for the clavicles and for the costal cartilage extending from rib 1.
The central, thin body provides articulation points for costal cartilage from ribs 2 through 7. Skip to main content. Last's Anatomy. Churchill Livingstone.
