A typical human wrist can rotate approximately 160-180 degrees.
This range of motion allows for a considerable degree of flexibility, essential for various daily activities and specialized tasks. The rotation is primarily achieved through the combined movements of the radiocarpal and midcarpal joints, as well as the contributions from the forearm muscles (pronation and supination).
Factors influencing the degree of wrist rotation include:
- Individual Anatomy: Variations in bone structure, ligament elasticity, and muscle strength can affect the range of motion.
- Age: Flexibility tends to decrease with age, potentially limiting the extent of wrist rotation.
- Activity Level: Individuals who regularly engage in activities that require wrist rotation may have a greater range of motion compared to those who don't.
- Injuries or Medical Conditions: Conditions such as arthritis, carpal tunnel syndrome, or wrist sprains can significantly restrict wrist rotation.
It's important to note that "rotation" in the context of the wrist typically refers to a combination of movements including pronation and supination of the forearm which contribute to what is perceived as wrist rotation. True wrist rotation independent of forearm movement is limited.
