Maximum pullout strength of pedicle screws in osteoporotic cadaver spines are tested. Bone mineral density was measured before by two noninvasive methods (QCT, DRA). Pullout direction was axial to screw axis. 210 N to 920 N were reached from D1-S1. T

Based on the data derived from the examination of 16 infantile and juvenile anatomical hip specimens as well as the radiological examination of 1350 hip joints of healthy children, a biomechanical model of the developing hip was computed. This two-di
