CA 2401421

A shaped particle (10) for use in an array of interlocking particles to repair, replace, improve or augment a bone deficiency is provided. The particle in a preferred embodiment has six extremities (20), and the interstitial spaces (60) between the extremities(20) of one particle accept the extremities of an adjacent particle in an array. The particle is suspended in a material which facilitates application of the particle to bone, and the material may contain biological factors which augment bone growth or prevent infection. Furthermore, a method of making a shaped particle by producing a hardened calcium sulfate material is provided.

L'invention concerne une particule façonnée destinée à être utilisée dans un système de particules de verrouillage en vue de réparer, remplacer, améliorer ou contrecarrer une carence osseuse. Dans un mode de réalisation préféré, ladite particule a six extrémités, les extrémités d'une particule du système pouvant se loger dans les interstices situés entre les extrémités d'une particule adjacente. La particule est en suspension dans une matière qui facilite l'application de ladite particule sur l'os et qui peut contenir des facteurs biologiques de croissance osseuse ou de prévention d'infection. En outre, l'invention concerne un procédé de fabrication d'une particule façonnée grâce à la fabrication d'un matériau de sulphate de calcium durci.
