The increased number of young, active individuals with amputation due to recent wars has focused more attention on direct skeletal attachment of limb prostheses. This article deals with the further development of the totally porous composite pylon for direct skeletal attachment. The minimum strength requirements established from the gait biomechanics data have been exceeded threefold. The histopathological analysis provides new evidence of inflammation-free deep ingrowth of skin and bone cells throughout the totally porous structure. These results may lead to the development of a pylon for safe and long-lasting direct skeletal attachment.
