title: [Computerized three-dimensional reconstruction and morphologic measurement of adult acetabulum bone structure].
abstract: OBJECTIVE
  To set up three-dimensional reconstruction of acetabulum bone structure from CT scanned image in computer with software of CAD and study quantitatively the morphologic features of the acetabulum.
  
  
  METHODS
  Through the process of CT scanning, and edge recording of the CT image, we made use of CAD software and Unigraphics software to reconstruct the 40 normal acetabulum bones for the radius of acetabulum (R), minimum thickness of medial wall of acetabulum (L), depth of Harris fossa (D) and maximum opening rim width in cross-sectional plane (W).
  
  
  RESULTS
  The average R was 30.48 +/- 2.05 mm. The average L was 2.35 +/- 1.13 mm. The average D was 5.71 +/- 1.21 mm. The average W was 63.06 +/- 2.05 mm. There was a linear relationship between the R and the W, but no correlation between the R, the L and the D.
  
  
  CONCLUSIONS
  There was a significance linear relationship between the R and the W in normal adult acetabulum. However no correlation between the R, the L and the D.
