CA 2459818

A band (14) of biocompatible and/or bioabsorbable material is provided including threads (26) on one or both of its ends. An area adjacent a spinal disc is accessed, and the band of material is wrapped around the disc to stabilize the disc and/or to facilitate healing. An elongate member (12) is inserted around a posterior region of the disc, e.g., through tubular guide members. An end of the band (18) is connected to a distal end (30) of the elongate member, and the elongate member is pulled back around the disc to direct the band around the disc. The band is secured around the disc overlapping vertebrae adjacent the disc. Optionally, a relative location of the vertebrae is adjusted relative to the disc before wrapping the band around the disc, for example, using a fork member (16) or traction. Energy may also be applied to the disc to enhance healing.

Cette invention concerne une bande de matériau biocompatible et/ou de matériau bioabsorbable comprenant des fils à l'une de ses extrémités ou aux deux. Après avoir accédé à une région adjacente à un disque vertébral, on enroule la bande de matériau autour du disque pour stabiliser ce dernier et/ou en faciliter la guérison. On insère un élément de forme allongée autour d'une région postérieure du disque, au moyen, par exemple, d'éléments tubulaires de guidage. On relie une extrémité de la bande à une extrémité distale de l'élément allongé et l'on tire ce dernier vers l'arrière autour du disque pour enrouler la bande autour du disque. La bande fixée autour du disque déborde sur les vertèbres adjacentes. On peut éventuellement corriger la position relative du disque avant de l'entourer de la bande, notamment é l'aide d'un élément à fourche ou par traction. La guérison du disque peut également être favorisée par application d'énergie.
