Methods of providing soft tissue impaction using anchored implants are disclosed. In some embodiments, the soft tissue impaction provided by the anchored implants can facilitate intervertebral disc reconstruction. A method of soft tissue impaction includes displacing soft tissue from within a defective region of an anulus into a nuclear disc space of an intervertebral disc as it is driven within an outer surface of an adjacent vertebral body.
1. A method of impaction grafting performed during anular reconstruction, the method comprising: identifying a defect of an anulus fibrosus of an intervertebral disc;providing an anchored implant comprising a bone anchoring member and an engagement member;positioning said engagement member proximate
1. A method of impaction grafting performed during anular reconstruction, the method comprising: identifying a defect of an anulus fibrosus of an intervertebral disc;providing an anchored implant comprising a bone anchoring member and an engagement member;positioning said engagement member proximate an outer surface of a vertebral body adjacent the defect;engaging soft tissue within the defect with the engagement member;partially implanting said bone anchoring member within the outer surface of a vertebral body adjacent the defect;wherein the bone anchoring member is inserted at an angle substantially perpendicular to the outer surface of the vertebral body;displacing said soft tissue from the defect and into a disc space of the intervertebral disc using the engagement member;fully implanting the bone anchoring member within said outer surface of said vertebral body;wherein no portion of the bone anchoring member extends proud of the outer surface of the vertebral body; andwherein said engagement member contains said soft tissue, thereby preventing said soft tissue from exiting through the defect. 2. The method of claim 1, further comprising removing at least a portion of a native nucleus pulposus of the intervertebral disc. 3. The method of claim 1, further comprising removing at least a portion of the anulus fibrosus. 4. The method of claim 1, further comprising inserting nuclear augmentation material within the disc space. 5. The method of claim 1, wherein the soft tissue comprises native nucleus material. 6. The method of claim 1, wherein the soft tissue comprises nuclear augmentation material. 7. The method of claim 1, wherein displacing said soft tissue from the defect and into a disc space of the intervertebral disc using the engagement member comprises increasing nuclear pressure. 8. The method of claim 1, wherein displacing said soft tissue from the defect and into a disc space of the intervertebral disc using the engagement member comprises increasing a volume of the disc space.
