Which joint exhibits more flexion than extension according to CPR?

The elbow joint is characterized by a greater range of flexion compared to extension. In anatomical positioning, the elbow can flex significantly, allowing for activities such as bringing food to the mouth or lifting objects closer to the body. The average peak of flexion in the elbow is around 145 degrees, whereas the extension is typically limited to about 0 degrees, reflecting a general tendency for flexion to surpass extension in functional use.

In contrast, other joints such as the knee also show significant flexion capabilities, but the extension range can vary, often leading to a more balanced articulation during movement. The talocrural joint, or ankle joint, primarily facilitates dorsiflexion and plantarflexion, with more emphasis on plantarflexion movements in daily activities. The glenohumeral (GH) joint, which is the shoulder joint, also has a broad range of motion in multiple planes, but its flexion and extension capabilities are more aligned than what is observed in the elbow.

Thus, when considering the specific characteristic of having more flexion than extension, the elbow stands out as the joint that primarily exhibits this feature in functional biomechanics.
