When treating depressed ribs, which rib is regarded as the key rib?

Bottom rib
Top rib
Adjacent rib
Any rib

The correct answer is: Top rib

In the treatment of depressed ribs, the top rib is considered the key rib. This is because the top rib, often referred to as the "key rib," serves as the primary reference point for the ribcage during manipulative interventions. The reason this rib holds such significance is that it can influence the position and motion of the surrounding ribs and the entire thoracic cage. When treating a depressed rib pattern, focusing on the top rib allows for the stabilization of the thoracic structure, helping to restore normal biomechanics and respiratory function. When the top rib is elevated or manipulated appropriately, it can help alleviate the effects of the depressed ribs below it by restoring proper thoracic mobility. This approach is important since the ribs work in a coordinated manner during breathing and other movements, and alterations in one rib can affect the entire ribcage. Therefore, identifying and treating the top rib during rib dysfunction can lead to improved outcomes in addressing rib restrictions and enhancing overall thoracic motion.
