An application of polyester bands in spinal stabilization

Polyesters have been applied in implantology for years, mostly for reconstruction of ligaments and tendons. For a few recent years, research has been conducted on their application in spinal implantology. Inter-process stabilizers may be an example of this. The aim of the work was to evaluate biofunctionality of knitted polyester applied in spinal alloplasty on the basis of macroscopic postmortem examination with microscopic HP tissue assessment. The tests were conducted on living animals – goats. Two kinds of bands with different characterictics and weave sizes were used in the tests. The results of the tests demonstrated usability and an acceptable level of safety of polyester implant application as components of a spinal stabilizer. Also, tests on animals revealed their high practicability in the evaluation of biotolerance, implantability, and the performance of implant elements as a biostabilizer after its implantation.
