Summary: | To investigate the key parameters of three-dimensional anatomy of the proximal humerus and compare the differences between male and female, and between left and right sides in Chinese by volume rendering technique with multi-slice spiral CT (MSCT) so as to provide a reference for a new prosthesis of the proximal humerus which can adjust to the anatomical characteristics of Chinese.
A total of 100 healthy volunteers were collected from Chongqing of China, including 59 males and 41 females with an average age of 40.4 years (range, 21-57 years). The humeral retroversion angle (RA), neck-shaft angle (NSA), medial offset (MO), and posterior offset (PO) were measured by volume rendering technique with MSCT. The average values were compared between male and female and between left and right sides, the correlation of these parameters was also analysed.
In 100 volunteers (200 sides), the RA was (19.9 +/- 10.6)degrees, the NSA was (134.7 +/- 3.8)degrees, the MO was (4.0 +/- 1.1) mm, and the PO was (2.6 +/- 1.3) mm. The |
