[Application of lumbar-pelvic fixation in lumbosacral reconstruction after resection of sacral tumors].

Objective: To evaluate the short-term clinical results of a new approach of lumbar-pelvic fixation for lumbosacral reconstruction after resection of sacral tumors.
Methods: Fifteen patients with sacral tumors underwent lumbar-pelvic fixation using TSRH-3D, CDH-M8 or ISOLA with iliac screws. The lumbosacral stability was evaluated according to the X-ray result to assess the feasibility and therapeutic effect of this approach.
Results: X-ray showed that high lumbosacral stability was achieved in all the 15 cases after the operation, and satisfactory therapeutic effect was obtained.
Conclusion: Lumbar-pelvic fixation with iliac screw is feasible for lumbosacral reconstruction after resection of the sacral tumors, which provides strong internal fixation and produce good clinical outcomes.
