Is the wrist joint uniaxial biaxial or multiaxial?

The wrist joint is primarily considered a biaxial joint. It allows movement in two planes: flexion and extension (sagittal plane) as well as radial and ulnar deviation (frontal plane). However, the wrist also facilitates some degree of rotation due to the complex interactions of the carpal bones, which can lead to some multiaxial characteristics. Overall, its primary classification remains biaxial.
