Hip joint prosthesis shank

摘要

The shank of a hip joint prosthesis (10) is made of fibre -reinforced plastic material in the form of the two shells (20,21) with undirectional fibres (14) which transverse the shank longitudinally. A filler core (17) is made of compressed short fibres e.g. the same carbon fibres as those for the shells. Core and shells are hardened hointly to effect an intimate connection. Alternaltively, the core can consist of a foam which is subsequently injected in the cavity.
