A Novel Modular Dynamic Stabilization System for the Treatment of Degenerative Spinal Pathologies

Özet

AIM: To show the preliminary clinical results of the Orthrus modular dynamic stabilization system that is a new instrumentationsystem intended for degenerative diseases of the lumbar spine.MATERIAL and METHODS: The system utilizes two different types of screws that can be used in conjunction with different typesof rods such as titanium, carbon fiber or PEEK. The first type of screw is a double headed screw to interconnect to the upper andlower level with independent rods. The second type of screw is a sliding screw to be used on a immovable vertebrae that allowsmovement in two planes on the tip.RESULTS: The system has been used on 36 patients with pathology varying from degenerative disc disease to degenerative lumbarscoliosis. Satisfactory results have been obtained in a all 36 patients in the 12-month follow-up period.CONCLUSION: The Orthrus dynamic system shows better clinical results than the available dynamic systems on the market. Italso proves to provide similar fusion with considerably less postoperative morbidity which makes it a better method to treat adultdegenerative spine diseases for carefully chosen patients.
