Coefficient of static friction at pig femoral osteotomies: the role of anatomic reduction and compression on the value of the coefficient.
The coefficient of static friction for pig femora following an osteotomy has been determined in vitro. It was found that the coefficient had a value of 0.46 +/- 0.05, and that this was independent of the reduction force applied to the osteotomy site, provided there was good anatomical reduction. When the osteotomy was not anatomically reduced, the coefficient of friction varied in a linear manner with the applied reduction force.
