Fig. 3From: The fusion rate of demineralized bone matrix compared with autogenous iliac bone graft for long multi-segment posterolateral spinal fusionA 80-year-old female underwent instrumentation and posterolateral fusion with DBM from L1 to L5 and received second operation for removal of implants. (Left) The postoperative 12-month image showed successful fusion mass formation with pedicle screws loosening. (Middle) The intraoperative image showed solid and continuous fusion mass formation. (Right) After removal of the implants, the plain radiographs showed continuous fusion mass formation from L1 to L5. f, fusion mass; p, pedicle screw hole; s, spinal processBack to article page
