The Internal Stress Pattern of the os Coxae

“…This axis has an inclination anteriorly of about 1 5 O and also 15O laterally (Debrunner 1975), depending on the width of the pelvis and its tilt. The axis coincides quite closely with the commonly calculated resultant vector (Pauwels 1965, Debrunner 1975, Hamacher & Roesler 1972. In the standing position the main force will be directed towards the sacro-iliac joint and there will only be a modest bending moment distal to the sciatic notch.…”

A Photoelastic Study of a Model of the Proximal Femu:A Biomechanical Study of Unstable Trochanteric Fractures

“…Calculated values of M/J varied from 0.40-0.60 (McLeish & Charnley 1970, Pauwels 1935, Rydell 1966, Williams & Svensson 1968 to 0.65-0.75 (Amtmann & Kummer 1968, Denham 1959, Hamacher & Roesler 1972, Inman 1947. In the same studies the joint force inclination (p) has been reported as being between 6' and 17' and the abductor pull direction (0) between 10' and 21°, while the femoral shaft inclination (I$) has been stated as being between 5 ' and 15O.…”
