User:Mr. Ibrahem/Slipping rib syndrome

Slipping rib syndrome (SRS) is a condition in which the false ribs are overly mobile. Symptoms include sharp pain at the lower aspect of the rib cage or in the abdomen with arm movement, leaning over, or coughing. Pain is often long term in nature. Complications may include depression.

The cause is typically unclear. Risk factors include genetics and prior injury. Those who play contact sports are more commonly affected. The underlying mechanism involves weakness of the costal cartilage that results in greater than normal movement of the 8th to 12th ribs and thus irritation of the intercostal nerves. Diagnosis is based on placing the fingers around the lower aspect of the rib cage and pulling outwards. If this results in a "click", movement, and the person's pain the condition is suspected. Diagnosis may also be supported by ultrasound.

Treatment may involve rest, NSAIDs, physical therapy, nerve blocks, and occasionally surgery to remove the involved cartilage. Outcomes are generally good. Though some cases may last year.

Slipping rib syndrome is uncommon, with estimated that it represents about 1-5% of lower chest and upper abdominal pain due to musculoskeletal causes. It is believed to be frequently misdiagnosed or underdiagnosed. Middle aged adults are most commonly affected. Women may be more commonly affected than men. It was first described by Edgar Ferdinand Cyriax in 1919, while the current name came into use in 1922.
