Abstract:
One hundred Chinese adult humeral heads (50 of either side) were studied with laser. The radius, height, angle as well as the surface area of each were anteriorly, laterally and obliquely measured in two-dimensions.The main results are as follows:1) The mean angle of the articular area was 144.48?11.9?.2) The average radius and height of the humeral head were 2.15?0.16 cm and 1.56?0.24 cm respectively. The articular surface height occupied 36.05 per cent of the diameter of the approximate spherical body.3) The mean articular surface area of the humeral head was 21.02?4.03cm~2. According to the radius of the humeral head and the articular surface angle, the curvature of the articular surface can be estimated and drawn out. That will offer the theoretical data of Chinese adult humeral head for the design and manufacture of artificial joint and artificial humeral head.
