A method of augmenting an intervertebral disc by injecting particles of collagen-based material into the disc. The particles may be dehydrated before implantation, and rehydrated after implantation, or they may be implanted in a "wet" state - such as a slurry or gel. Radiocontrast materials may be included to enhance imaging of the injected material. Other additives may include analgesics, antibiotics, proteoglycans, growth factors, and/or other cells effective to promote healing and/or proper disc function.
L'invention concerne un procédé permettant d'augmenter un disque intervertébral par injection de particules d'un matériau à base de collagène dans le disque. Les particules peuvent être déshydratées l'injection, puis réhydratées après l'injection, ou encore, elles peuvent être injectées à "l'état humide" (par exemple sous la forme d'une pâte ou d'un gel). Des matériaux de contraste radiologique peuvent être ajoutés afin d'améliorer la formation d'images du matériau injecté. D'autres additifs peuvent comprendre des analgésiques, des antibiotiques, des protéoglycanes, des facteurs de croissance, et/ou d'autres cellules favorisant la cicatrisation et/ou le fonctionnement correct du disque.
