Vertebroplasty with Calcium Composite Bone Graft Combined with Pedicle Screws Fixation in Thoracolumbar Fractures

Introduction: Posterior reduction probably reduces only the periphery of the endplate with its strong annular attachments while the central area remains depressed allowing for efficient realignment of the spine, direct and indirect decompression. With distraction force, restoration of vertebral body height and partial clearance of bone or discal fragments from within the spinal canal by ligamentotaxis can be achieved; the kyphosis gradually recurs in the rehabilitative phase. Aim of the Work: To evaluate the therapeutic effect of vertebroplasty with calcium composite bone graft (GeneX) R combined with pedicle screws fixation in thoracolumbar fractures. Patients and Methods: The study was performed on 29 vertebrae in 24 patients with burst fractures for whom transpedicular calcium composite bone graft (GeneX) and posterior spinal fixation was performed. Results: By using transpedicular calcium composite bone graft (GeneX) and posterior spinal fixation success was detected by immediate and follow-up of cobb's angle. Conclusion: Transpedicular restoration of endplate integrity and anterior column support by calcium composite bone graft (GeneX) and posterior spinal fixation is an effective and safe method to prevent later collapse.
