Yes, lower ribs move, but the extent of their movement varies. While the upper ribs are more firmly attached to the sternum (breastbone), the lower ribs, especially the floating ribs (11th and 12th), have more mobility. This increased mobility is a key factor in conditions like slipping rib syndrome.
Understanding Rib Movement
- Upper Ribs: These ribs are more stable due to their direct connection to the sternum.
- Lower Ribs (8th, 9th, 10th): These are less firmly attached to the sternum, making them prone to excess movement. This increased mobility can be a source of pain or discomfort. [Source 1]
- Floating Ribs (11th, 12th): These ribs are not connected to the sternum at all, allowing for even greater movement. Their mobility is why they are often involved in slipping rib syndrome. [Source 1] Slipping rib syndrome involves pain in the lower chest or upper abdomen when the lower ribs move more than normal. [Source 2, Source 3, Source 4, Source 5] The movement in slipping rib syndrome is described as subluxing, and typically causes pain when twisting. [Source 3]
While some movement in the lower ribs is normal during breathing and other body movements, excessive movement can lead to pain and discomfort. A doctor can diagnose and treat such conditions. For instance, a doctor might use a "hooking maneuver" to assess rib movement. [Source 5] Furthermore, the bottom two ribs rarely break because they can move more than the upper and middle ribs. [Source 7]
In some cases, individuals may experience hypermobility in their ribs, leading to the ability to consciously "pop" their ribs, which can be uncomfortable or even painful. [Source 9] It is important to note that intentionally manipulating the ribs should be avoided. If you are experiencing pain or discomfort in your ribs, consult a medical professional.
