  • Definitions

    • For this text, the hand will be defined as beginning at the carpometacarpal joint
    • In anatomic position, hand is in supination
      • Thumb points away from body, palm faces forward
    • Radial: Toward radius and synonymous with lateral(ly)
    • Ulnar: Toward ulna and synonymous with medial(ly)
    • Mesial: Toward midline of structure
      • In the hand, for example, 3rd digit is more mesial than 2nd and 4th digits, which are more mesial than 1st and 5th digits
