What is Slipping Rib Syndrome?

Due to various factors, such as trauma or degeneration, disruption of the interchondral attachments between ribs 8 through 10 can result in weakness and rib separation at the costal margin.

This results in hypermobility and subluxation of the rib; the tip of the hypermobile rib can impinge on the intercostal nerve of the rib above, causing a complex pain response. This interaction between the rib tip and the intercostal nerve results in pain with activity and movement, leading to limitations in quality of life.

Intercostal nerves are highly sensitive and prone to producing chronic pain when injured. It may generate severe pain in a dermatomal distribution in the affected intercostal space, originating anteriorly and radiating back to the spine. Such intercostal neuralgia is the predominant symptom observed in SRS.

To diagnose slipping rib syndrome, it is required to have an examination conducted by specialized medical professionals who possess knowledge and training in this rare syndrome. 

In many cases, radiologic imaging of the chest and abdomen, such as chest X-rays, MRIs, and regular CT scans, do not reveal any abnormalities. While costal cartilage may not be visible in regular CT scans, 3D CT or High-Resolution scans can uncover protruding ribs and costal cartilage. High-resolution ultrasound (Dynamic ultrasound) can confirm the ribs' movement and compression of muscles, tendons, and intercostal nerves. 

Although Slipping Rib Syndrome was identified by a British orthopedic surgeon in 1919, it remains a relatively obscure condition in the medical field. Its impact on various parts of the body also makes it challenging to diagnose, frequently leading to misdiagnosis.

Due to a lack of awareness, only a limited number of specialists and surgeons can diagnose and treat slipping rib syndrome. We aim to increase awareness of this debilitating condition, "Slipping Rib Syndrome," to expand access to diagnosis and treatment.
