Abstract
Abstract An implant (prosthesis) comprising a batch of a mixture of porous grains/granular material of tissue-compatible type and disintegrated tissue-compatible biological material (preferably endogenous material, such as bone meal). The batch further comprises a component which allows moulding or modelling of the batch, and the batch is enclosed in a pouch or wrap made of a flexible tissue-compatible material and having pores/apertures/perforations or the like of a size which allows outgrowth and ingrowth of tissue of the biological material. The implant is applicable in many contexts, such as a fixing agent for a hip-bone prosthesis, as a filler in plastic surgery and as a bone growth promoting agent when treating rheumatism.
