- W1593296856 abstract "This is a retrospective long-term outcome study of results after laminectomy for lumbar spinal stenosis in an elderly group of patients. The study was designed to evaluate possible demographic, comorbidity, and clinical prognosticators for pain reduction and functional improvement in this population. Because the assessment of functional outcome in the elderly is complicated by several specific factors, the use of outcome measurement parameters should be revised and refined. Moreover, despite numerous relevant studies, the results of various techniques remain equivocal, particularly among the elderly, which renders the implementation of focused studies necessary. New data could be used to refine patient selection and choice of technique to improve prognosis.During a 5-year period, lumbar laminectomies were performed in 182 elderly patients. Of these 182, 125 patients (68.8%) were followed up for a mean period of 60.8 months. The outcome was assessed by means of pain visual analog scale (VAS) pain score, Oswestry Disability Index (ODI), and patient satisfaction questionnaire, and results were correlated to demographic (age, sex), comorbidity (Charlson Comorbidity Index, diabetes, depression, and history of lumbar spine surgery), and clinical (main preoperative complaint, preoperative VAS score, and ODI) factors.In terms of the VAS score, 106 patients (84.8%) exhibited improvement at follow-up. The corresponding ODI improvement rate was 69.6% (87 patients). The mean VAS and ODI differences were 5.1 and 29.1, respectively. One hundred two patients (81.6%) were satisfied with the results of the operation. Univariate analysis for possible prognostic factors revealed the significant influence of low-back pain on VAS score (p = 0.024) and ODI (p < 0.001) not improving, while the ODI was also affected by sex (females had a poorer outcome [p = 0.019]). In contrast, patient satisfaction was not related to any of the preoperative parameters recorded; nevertheless, it was strongly related to all functional measurements on follow-up.Considering the methodological issues of such studies, particularly in elderly patients, the authors conclude that the ODI is more sensitive than the VAS score in assessing prognostic value and that patient satisfaction is difficult to prognosticate, underscoring the particularities that this population presents regarding functionality assessment. Considering the prognostic value of preoperative factors, a negative influence of low-back pain and female sex is reported." @default.
