  • Definitions

    • For this text, the hand will be defined as beginning at the carpometacarpal joint
    • In anatomic position, the hand is in supination
    • Radial: Toward radius and synonymous with lateral(ly)
    • Ulnar: Toward ulna and synonymous with medial(ly)
    • Mesial: Toward midline of structure
      • 3rd digit is midline of hand and therefore the most mesial structure
      • 2nd and 4th digits are more mesial than 1st and 5th digits
    • Abduction is motion away from midline of structure
    • Adduction is motion towards midline of structure
