Surgical results of Degenerative Spondylolisthesis patients over 70 years old: A single-center experience and clinical outcomes

Abstract

AIM: The aim of this study is to evaluate results of surgery in Degenerative Spondylolisthesis (DS) patients over 70 years old. MATERIAL and METHODS: This is a non-randomized retrospective analysis of the clinical outcome of 34 patients older than 70 years who underwent surgery. At the end of two-year follow-up period, preoperative and postoperative courses were assessed by Oswestry Disability Index (ODD and Visual Analog Scales (VAS). RESULTS: The mean age was 75 years (range 70-86 years). The mean duration of symptoms was 13.5 years (range 2-30 years). All patients underwent physiotherapy and also 15 (11 female, 4 male) patients used brace. L4-L5 was the most commonly affected level (n=26), Preoperative ODI and VAS scores were mean 71,63 (range 34-100) and 6,77 (range 2-9) (p<0,05). Postoperative ODI and VAS scores were mean 22,73 (range 0-100) and 2,13 (range 0-10) (p<0,05). Patients were asked if they had known the outcome, would they accept surgical treatment or not. 86.6% (n=26) of the patients answered the question positively. CONCLUSION: A conventional decompressive laminectomy with foraminotomy and posterolateral fusion in situ with transpedicular instrumentation is necessary and reduces pain and recovers functional disability in elderly patients over 70 years old with DS..
