What is the normal range for extension at the radiocarpal joint?

The normal range for extension at the radiocarpal joint is indeed 70-90 degrees. The radiocarpal joint, which is where the radius and the first row of carpal bones meet, plays a crucial role in wrist movement. When evaluating the normal range for wrist extension, it is essential to consider typical functional movement patterns and anatomical studies.

In this case, a range of 70 to 90 degrees is generally accepted in anatomical literature and clinical practice as it aligns with the average capabilities observed in healthy individuals. This range allows for effective wrist function, which is necessary for various daily activities and physical tasks.

Understanding the normal ranges for joint movements is vital in assessing, diagnosing, and treating musculoskeletal conditions, as well as planning appropriate rehabilitation strategies for individuals.
