Clinical results after surgical treatment in young male patients with low grade isthmic spondylolisthesis

Purpose:the aim of this study is to evaluate the long term results of surgical treatment in young patients with low grade isthmic spondylolisthesis (is). materials and methods:postoperative clinical results of 42 patients ageing between 20-29 were retrospectively analized in this study. oswestry disability index (odi) and visual analog scales (vas) scores were used to compare patients’ preoperative and postoperative pain levels. results: all patients were male and the mean age of patients was 23.4 (between 20-29). mean duration of symphtoms was 1.8 years (between 1-4 years). all patients had physical therapy before surgery and 24 patients (%57.1) used lumbosacral brace. isthmic spndylolisthesis was present in l5-s1 level in 78.5% (n=33) and in l4-5 level in 21.4% (n=9) of the patients. mean preoperative odi and vas scores were 76.68 (between 43-100) and 5.98 (between 3-10), respectively (p<0.05). mean postoperative odi and vas scores were 26.65 (between 0-66) and 2.49 (between 0-5), respectively (p<0.05). conclusion:posterolateral in stu fusion and transpedicular instrumentation in young well-selected patients with low grade is reduce pain, improve function and result good clinical outcome. prospective and multicenter studies with 10-20 years follow-up are needed for further data.
