Methods for injecting a curable biomaterial into an intervertebral space |
摘要 |
A method for treating a diseased or damaged spinal disc having an inner nucleus pulposus and an outer annulus is provided comprises the steps of: providing access to the nucleus pulposus through the annulus; removing at least a portion of the nucleus pulposus to create an intradiscal space; determining the integrity of the annulus; and then sealably introducing under pressure a curable biomaterial through the annulus access directly into the intradiscal space. The step of determining the integrity of the annulus may be accomplished by introducing into the disc a fluid solution under a first pressure. The curable biomaterial may subsequently be introduced through the annulus directly into said intradiscal space at a second pressure that is increased or decreased from the first pressure as a function of the viscosity of the biomaterial relative to the fluid solution. In certain embodiments, a distraction force is applied to the disc space.
