Figures
- Figure 1
Demineralized bone fiber anchors of different diameters. All are 30 mm in length.
- Figure 2
(A) A loose screw is identified intraoperatively and subsequently explanted. (B) An appropriately sized demineralized bone fiber anchor is placed into the cannulated pedicle screw tract. (C) A screw of the same diameter is then placed through the anchor.
- Figure 3
Demineralized bone fiber anchor insertion into a pedicle void from an explanted screw during revision surgery.
- Figure 4
(A–C) Preoperative computed tomography (CT) images showing pedicle screw lucencies indicative of left L5 and right S1 screw loosening. (D–F) Postoperative CT at 12 months showing reconstitution of posterior cortical and periprosthetic cancellous bone with no evidence of left L5 or right S1 screw loosening.
