MACHADO, Fabrício Guedes e ISHI, Marcos Masayuki. Clinical outcomes with non-fusion stabilization in low back pain. Coluna/Columna [online]. 2011, vol.10, n.4, pp. 329-331. ISSN 1808-1851. http://dx.doi.org/10.1590/S1808-18512011000400017.
OBJECTIVE: To evaluate the clinical outcome of surgical treatment of degenerative disc disease (DDD) with the use of pedicular stabilization systems without fusion in 22 patients in the city of Aracaju/Sergipe. METHODS: We used the visual analogic scale (VAS) and quality of life questionnaires (Oswestry and Roland Moris) preoperatively and 6 months after surgical treatment. According to the clinical symptoms and morpholophysiological changes found in the imaging exams, articular changes (facet degeneration), disc disease at adjacent levels, previous microdiscectomy, were determinant parameters for chose the use of implants that allow varying degrees of mobility. RESULTS: Of the 22 patients studied, 16 were male and six female with mean age of 41.77±11.6 years.A total of 43 levels were stabilized and the instrumentation from L4 to S1 was the most frequent segment (12) and the Dinamika® (GMReis - Brazil) plate for 2 levels was the most frequent used system (08), with fusion of the lower level (hybrid stabilization). There was significant improvement in symptoms when we observe a decrease of VAS preoperatively (8,59±1,1)and 6 months postoperatively (2,41±1,8) with improvement in quality of life scores in Oswestry and Roland Moris questionnaires (ODI pre: 55,18±15.5 and ODI post: 13,91±13,1 ; RM pre: 27,23 ± 4,9 e RM post: 41,68 ± 4,8), respectively. CONCLUSION: Although all patients included in the study had achieved a significant improvement both in quality of life and in reducing symptoms, further biomechanical studies should be performed in order to standardize an efficient approach to treat this pathology.
