1 Radiographic Anatomy and Positioning of the Upper Extremity

2 Intended Learning Outcomes The student should be able to recognize clinical radiographic technical principles of the upper limb

3 Upper extremity consists of: Phalanges Metacarpals Carpals Radius Ulna Humerus

4 The hand & wrist consists of : 27 Bones –Phalanges - 14 –Metacarpals - 5 –Carpals - 8

5 Phalanges Fingers & thumb 3 separate bones Digits 2-5 –Proximal –Middle –Distal Tuft Thumb –Proximal –Distal

6 Naming of Digits Thumb Index Middle Ring Little

7 Joints Interphalangeal Metacarpophalangeal Distal Interphalangeal Proximal Interphalangeal

8 Metacarpals Palm Numbering Three parts –Head –Shaft –Base Joints –MP –Carpometacarpal Head Base Shaft

9 Carpals (Wrist) 8 bones Proximal row aScaphoid bLunate cTriquetrum dPisiform a b c d
