  1. MODULE 7 HIP

  2. HIP: NORMAL ANATOMY AND POSITIONING • Three views • AP • Lateral • Frog Leg

  3. LINES OF MENSURATION • Teardrop distance • Maximum of 11.0mm, minimum of 6.0mm, with an average of 9.0mm • Waldenstrom sign

  4. Fig 3-48A Teardrop distance

  5. Fig 3-48A Increased Teardrop distance

  6. LINES OF MENSURATION • Hip joint space width • Three measurements • superior • axial • medial (aka - teardrop) • Pattern of collapse is very important to note

  7. Hip joint space width

  8. LINES OF MENSURATION • Acetabular Depth • <7.0mm in males and 9.0mm in females • Dysplasia has an intact joint space • Rheumatoid arthritis has a loss in joint space

  9. Acetabular Depth Fig 3.50a

  10. LINES OF MENSURATION • Center-edge angle • Represents “coverage” of femur head by acetabulum • Minimum of 20o, maximum of 40o, with an average of 36o

  11. Center-edge angle Fig 3.51a

  12. LINES OF MENSURATION • Symphysis Pubis Width • Increased width is indicative of cleidocranial dysplasia, bladder exostrophy, HPT, trauma - diastasis, osteolysis - ankylosing spondylitis, osteopubis, gout

  13. Symphysis Pubis Width Fig 3.52a

  14. Symphysis Pubis Width Fig 3.52b

  15. LINES OF MENSURATION • Acetabulur angle • Minimum 12o, maximum 29o, with an average of 20o • Increased angle is indicative of dysplasia, congenital hip dislocation • Decreased angle is indicative of Down’s syndrome

  16. Acetabulur angle Fig 3.54

  17. LINES OF MENSURATION • Protrusio acetabuli (Kohler’s line) • Femur head should be lateral • If acetabulum floor crosses line - idiopathic, rheumatoid arthritis, Paget’s (osteomalacia)

  18. Kohler’s line Fig 3.57b
