In a previous study the results have also demonstrated a correlation between the outcome of the test and the severity of pain, as well as the prognostic value of the test; patients for whom the SLR test is persistently positive postoperatively appear to have a poorer short-term outcome. In a prospective study of 200 consecutive patients who underwent surgery for disc herniation, the authors evaluated the frequency of repeated surgery and outcome of surgery in patients with a persistent postoperative positive SLR test.<\/jats:p>\n<jats:p content-type=\"fine-print\"><jats:italic>Methods.<\/jats:italic> The preoperative radiological evaluation included myelography, computerized tomography scanning, and\/or magnetic resonance imaging. Preoperatively as well as 4, 12, and 24 months postoperatively, each patient was interviewed and examined using a standard protocol in which common symptoms and signs were described. The result of the SLR test was also classified into one of four categories: positive 0 to 30\u00b0; positive 30 to 60\u00b0, positive greater than 60\u00b0, or negative, and the surgical results were evaluated using a four-grade scale.<\/jats:p>\n<jats:p content-type=\"fine-print\">Preoperatively, the SLR test was positive in 86% of patients. At 4 months postoperatively, 22% still had a positive SLR test. For the patients whose SLR test was positive 4 months postoperatively, the long-term outcome at all three follow-up examinations was inferior; this difference was statistically significant.<\/jats:p>\n<jats:p content-type=\"fine-print\"><jats:italic>Conclusions.<\/jats:italic> During the 2-year period, the reoperation rate was 18% (eight of 44) in patients with a positive postoperative SLR test compared with 4.5% (seven of 156) in patients whose postoperative SLR test was negative. A postoperative positive SLR test thus correlates to an unfavorable surgical outcome.<\/jats:p>","DOI":"10.3171\/spi.1999.91.1.0050","type":"journal-article","created":{"date-parts":[[2009,5,7]],"date-time":"2009-05-07T15:45:53Z","timestamp":1241711153000},"page":"50-53","source":"Crossref","is-referenced-by-count":1,"title":["Significance of a persistent positive straight leg raising test after lumbar disc surgery"],"prefix":"10.3171","volume":"91","author":[{"given":"Bo","family":"J\u00f6nsson","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Bj\u00f6rn","family":"Str\u00f6mqvist","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1754","reference":[{"key":"b1","series-title":"J Bone Joint Surg (Am)","doi-asserted-by":"publisher","first-page":"1178","DOI":"10.2106\/00004623-199072080-00008","article-title":"Abnormal magnetic-resonance scans of the cervical spine in asymptomatic subjects.
