[Transmission of forces at the carpal arch in hyperextension of the wrist--mathematical model].
The carpus is a remarkable anatomical structure which combines exceptional mobility and great resistance to stress in all positions. The carpal architecture is the most economical structure in terms of achieving these two functions: mobility and mechanical resistance. The mechanical behavior of the carpus can be studied through a vectorial and analytical analysis of the transmission of loads. This analysis permits determination of the repartition of strains at the level of the carpal arch and the role of important structures such as the transverse carpal ligament. By this analysis it is also possible to anticipate the result of certain surgical procedures such as the wedge osteotomy for Kienböck disease.
