What is the range for ulnar deviation at the radiocarpal joint?

The range for ulnar deviation at the radiocarpal joint is typically around 30 to 45 degrees. This movement refers to the wrist bending toward the ulnar side, which can be observed when the hand is positioned palm down and the little finger moves closer to the forearm.

This range is an important aspect of wrist mobility and is clinically significant for assessing wrist function and diagnosing potential injuries or conditions that might restrict movement. It's crucial for healthcare professionals to know this range to properly evaluate a patient’s wrist function, as deviations from this norm may indicate underlying issues such as ligament injury, arthritis, or other musculoskeletal conditions.

The other ranges presented in the options are larger than what is typically expected for ulnar deviation at the radiocarpal joint. Recognizing the standard range helps ensure that proper assessments and interventions can be made based on accurate anatomical and physiological knowledge.
