Objective
To introduce the technique of minimally invasive percutaneous pedicle screw osteosynthesis using Sextant system. and report our clinical experience in spine injury.
Methods
Between January 2003 to December 2004, 27 patients with thoraco-lumbar burst fracture were treated using Sextant system. The pedicle screws were put through new designed instrumentation, using the "C" arm fluoroscopic guidance and inserted percutaneously. 17 patients underwent only this procedure without anterior or posterior arthrodesis. For this group, peri-operative parameters and the index of image were analysed and compared with the treatment of traditional open pedicle screw osteosynthesis reported in the literature.
Results
The Sextant system allowed small incision, less paraspinous muscles injury, less blood loss, and no drain. Pedicle srew rod fixation was safety. Two srew violations of pedicles without neurologic damage needed replacement by the same minimally procedure. Postoperative pain was reduced with no intravenous narcotic use after 3 days. Average length of stay was 8.9 days. Clinical and radiological outcomes for 3 and 6 months follow-up periods showed no late complication, no significative loss of correction compared to "gold standard" ostéosynthesis.
Conclusions
Minimally invasive percutaneous pedicle screws-rod osteosynthesis has the advantages to be less aggressive in terms of bleeding, muscle injury, postoperative pain. The hospital stay is reduced. But correction of the traumatic kyphosis and bone grafting is not possible by this surgical technique alone.
