TI  - Measurement of the humeral head retroversion angle. A new radiographic method.
PG  - 406-9
AB  - BACKGROUND: In this study, a simple and reliable radiographic method is described 
      to determine the torsional profile of the humeral head. METHODS: First, by using 
      a specially developed frame, the humeral head retroversion angles (HRAs) of 20 
      dry humeri were measured by an anatomist and an orthopedist. Then the HRA of 
      these humeri were measured by two orthopedists on radiographs taken in semi-axial 
      view when the humeri were in 20 degrees abduction. RESULTS: The results were 
      assessed with the SPSS 9.05 program, and the repeatability coefficient of both 
      methods was 98%. The average difference in angle determination between the two 
      methods was 0.9 degrees; the maximum difference was 3 degrees. After that, 
      posteroanterior semi-axial radiographs of both humerus bones of 40 healthy 
      volunteers were taken by positioning their arms in 20 degrees abduction to the 
      X-ray axis. The mean HRA difference between the right and left sides was 0.4 
      degrees (maximum difference 3 degrees ) and is of no clinical significance. It 
      was determined that left and right HRAs can be taken as a reference to each 
      other. For measurement of the HRA in the planning of proximal humeral rotation 
      osteotomy and prosthesis replacement arthroplasty, the presented radiographic 
      method can be used with a high rate of accuracy.
