['The authors assessed options for vertebral body replacements with the Synex telescopic expansion cage. Autologic or homologic bone grafts, a titanium "Harm\'s" cage or a polymethylmetacrylate filling reinforced by Kirschner wires, may be used for vertebral body replacements. The cement filling is indicated in oncological patients, the Harm\'s cage requires filling with a quantity of bone grafts and, with massive bone grafts, the collection place or the graft availability may be a problem. The telescopic expansion implant is fairly easy to implant, is stable and requires to be filled with a minimum of spongious grafts.', 'From May 2001 to November 2005, 20 telescopic Synex cages were implanted in 18 patients. Vertebral body replacements were performed 14x for acute fractures, 4x for posttraumatic kyphosis and 2x for metastatic skeletal disorder in breast and prostate tumors.', 'Vertebral body replacement was completed with posterior transpedicular stabilization in 14 subjects, in 5 subjects, additional anterior Ventrofix stabilization was performed. Vertebral body replacements down to the L1 level were conducted through thoracotomy or video-assissted minithoracotomy, L2-L4 replacements from lumbotomy or anterior retroperitoneal approach.', 'The most requently affected and operated vertebrae included the L1 (4 patients), Th12 (4 patients), Th6 (3 patients). The minimal interval between the procedure and a follow- up was 12 months. No fatal outcome has been recorded. In one patient with a vertebral body metastasis, the disorder has generalized and in a second one, no further metastatic spread has been reported. In one subject, the left-sided L4 root injury was recorded postoperatively, a cauda equina syndrome, diagnosed after the injury, persits in one subject. No signs of deep infection have been recorded. There are no records of the Synex release or displacement. Correction loss (kyphotisation) of up to 2 degrees was recorded in patients with transpedicular stabilization, in Ventrofix patients the loss was up to 5 degrees, except one case, where the loss reached 10 degrees.'] Do [ Vertebral body replacement with a Synex implant ]?
