context_page_description: In human anatomy, the wrist is variously defined as 1 the carpus or carpal bones, the complex of eight bones forming the proximal skeletal segment of the hand; the wrist joint or radiocarpal joint, the joint between the radius and the carpus and
  the anatomical region surrounding the carpus including the distal parts of the bones of the forearm and the proximal parts of the metacarpus or five metacarpal bones and the series of joints between these bones, thus referred to as wrist joints. This region also includes the carpal tunnel, the anatomical snuff box, bracelet lines, the flexor retinaculum, and the extensor retinaculum.
  As a consequence of these various definitions, fractures to the carpal bones are referred to as carpal fractures, while fractures such as distal radius fracture are often considered fractures to the wrist.
context_section_description: It has two articular surfaces named, proximal and distal articular surface. The proximal articular surface is made up of lower end of radius and triangular articular disc of the inferior radio-ulnar joint. On the other hand, the distal articular surface is made up of proximal surfaces of the scaphoid, triquetral and lunate bones.
