Abstract:
Objective-To-discuss-the-clinical-efficacy-of-limited-decompression-and-pedicle-screw-fixation-for-thoracolumbar-burst-fractures.-Methods-From-October-2005-to-October-2011,-38-patients-with-thoracolumbar-burst-fractures-were-treated-by-lumbar-pedicle-screw-fixation-combined-with-limited-decompression-.The-X-ray-measurements-and-evaluations-of-neurological-functions-before-and-after-surgery-were-reviewed-.-Results-All-the-38-cases-were-followed-up-for-36-months.The-bone-fusion-was-obtained-in-all-the-cases-,-without-pedicle-screw-breakage-,-bending-,-or-prolapse-.Evaluation-of-the-efficacy-at-36-months-after-surgery:excellent-in-36-cases,-good-in-1-case,-and-poor-in-1,-with-a-good-or-excellent-rate-of-97.4%-(37/38).The-preoperative-anterior-height-of-fractured-vertebrae-was-(14.23-±2.51)-mm,-which-was-significantly-lower-than-that-6-months-postoperatively-[(25.68-±3.95)-mm,-q=22.319,-P<0.05],-24-months-postoperatively-[(26.23-±3.15)-mm,-q=23.391,-P<0.05],-and-36-months-postoperatively-[(25.64-±2.86)-mm,-q=22.241,-P<0.05].The-preoperative-Cobb-angle-was-(24.39°±2.54°),-which-was-significantly-more-than-that-36-months-after-surgery[(15.54°±1.05°),-q=27.448,-P<0.05].The-preoperative-VAS-scores-were-(6.1-±1.1)-points,-which-were-significantly-higher-than-that-36-months-after-operation-[(1.2-±0.6)-points,-q=33.930,-P<0.05].There-were-significant-differences-in-the-Frankel-grades-before-and-after-the-operation-(Z-=-2.190,-P-=0.029).-Conclusion-Limited-decompression-and-pedicle-screw-fixation-for-thoracolumbar-burst-fractures-can-not-only-provide-instant-stability-,-but-also-have-advantages-of-high-satisfaction-rate-,-minimal-invasion-,-and-long-term-prevention-of-kyphosis-and-fixation-failure-.
