Technique stabilization of spine after removal vascular tumor and malformations of spine
Keywords:
vascular formation of the spine, spinal stabilizationAbstract
The efficacy of surgical spine stabilization after removal of spinal vascular tumors and malformations is evaluated from a retrospective analysis of 37 case histories of patients. Neurovisual findings, clinical symptoms, surgical strategy, and instrumentation techniques of the spine are analyzed. Results of treatment patients with vascular tumors and malformations were assessed depending on method of spine stabilization.
The study concluded that preferred method of vertebral body reconstruction in case of anterior localization was the space after bone removal was packed with a titanium cage filled with bone fragments. The combination of a titanium cage and an anterior locking plate can be made easily for anterior spinal fusion with enough rigidity to maintain the necessary space during fusion without any major support equipment. Both edges of the titanium mesh cage cut into the vertebral body to hold the cage in place. The other part, the titanium plate, makes it secure until ceramic bone fragments in the cage promote bony ingrowth for fusion.
In case of posterior localization or lesions of posterior part of vertebral body the favorite method was a single midline posterior approach, and performed single-stage circumferential decompression of the theca followed by anterior and posterior reconstruction. A titanium mesh packed by bone fragments provides anterior support. Posterior reconstruction is achieved by placement of pedicle screw and rod instrumentation. We demonstrate the technique, feasibility, and success of vertebrectomy that is followed by anterior and posterior reconstruction via a simple posterior approach.
Conclusion. Adequate vertebroplasty and stabilization of the spine promote a more complete rehabilitation of patients and improve the quality of their life.
