Objective: Report safety and clinical outcomes of percutaneous intradiscal decompression procedures in patients with discogenic pain that failed conservative treatment. Minimally invasive surgical treatments are a trend. Methods: A retrospective study describing the clinical outcomes of patients treated with Nucleoplasty TM and DeKompressor TM , with follow up of 5 years. Results: Thirty-four (n=34) patients underwent intradiscal decompression with a follow-up period of 5 years, 21 had resolution of pain, eight underwent lumbar interbody arthrodesis, one underwent surgical discectomy and 4 had residual back pain. There were no adverse events. Conclusion: It was demonstrated the same safety obtained in other studies that also evaluated the use of triangular safety zone for percutaneous procedures. The success rate with the percutaneous procedure is similar to other studies published in a recent meta-analysis. The comparative studies, prospective and controlled will be useful to better define the effectiveness of percutaneous procedures.Keywords: Intervertebral disc displacement; Decompression; Intervertebral disc; Low back pain.
RESUMO
Objective:Radiographic evaluation of patients with thoracolumbar burst fractures treated with unconvencional transpedicular fixation, which includes additional fixation of the fractured vertebra associated with transverse connector - Crosslink clamp.Methods:Retrospective study evaluating a total of 68 patients operated at the Hospital do Trabalhador de Curitiba, Orthopedics Service, of which 15 were eligible for the study. All patients were treated with posterior pedicle fixation and intermediate screw. The assessment by the Cobb angle method was performed on preoperative, immediate postoperative and one year after surgery radiographs.Results:It was observed an average reduction of kyphosis of 8.3o (77%), with a loss of 1.34o in late postoperative compared to the immediate postoperative period.Conclusion:The method of fixation of burst-type fractures of the thoracolumbar spine by the posterior approach with intermediate screw was effective in maintaining the reduction achieved in the immediate postoperative period and after one year of evolution.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
