Anterior and Posterior Approach Results for Treatment of Cervical Myelopathy in the Elderly: A 10-Year Experience in a Mexican Institution

摘要

Introduction: Degeneration of the cervical spine (CDSD) prevalence is nearly 90% by the 7th decade. This is the first research that compares the outcomes between the Anterior Approach (AA) and Posterior Approach (PA) to cervical myelopathy (CM) in the elderly. Materials and Methods style="font-family:Verdana;">: A retrospective observational study of electronic health records at the Hospital Central Sur de Alta Especialidad (HCSAE), PEMEX from January 2010 to May 2020 with patients older than 60 years submitted to cervical surgery. For the analysis we elaborated two groups according to the surgical approach: AA vs PA;we analyzed the trans-operative behavior, the immediate outcome, and after 3 months, 6 months, and 1 year. style="font-family:Verdana;">Results style="font-family:Verdana;">: style="font-family:Verdana;">As style="font-family:Verdana;">a total of 145 patients, the prevalence of CM in elderly was the 63.8% with a median age of 69 (64 - 75) years. We found statistical differences in strength outcome only in the P3m (p = 0.011), for sensitivity "=""> style="font-family:Verdana;">we found major prevalence of affection in the PA group. We didn’t report a significant difference in the Neck Disability Index (NDI) at all measures, but the PA presented a major incapacity. The Nurick scale results were significant in all stages (p < 0.05);and presented improvement compared with presurgical period (p < 0.001) style="font-family:Verdana;">. "=""> style="font-family:Verdana;">Discussion style="font-family:Verdana;">: Patients show significant improvements in outcome measures with either anterior or posterior surgery. Both approaches are highly efficacious in preventing neurologic deterioration and in most cases improve neurological function with appropriate postoperative management like rehabilitation, pain management style="font-family:Verdana;">, "=""> style="font-family:Verdana;"> and psychological support. style="font-family:Verdana;">Conclusion style="font-family:Verdana;">: The patients submitted to surgical medullary decompression presented a favorable outcome despite the age and the higher prevalence of comorbidities;whereby we favor the surgical treatment in all patients in a case-to-case selection to generate a positive impact on functional outcomes.
