It was possible to follow 98% of patients from the time of operation to the time of writing. The mean follow-up period was 10.8 years. The most common presenting complaint was back pain with sciatica in one leg; the most frequent neurological finding was impaired straight-leg raising. Myelography confirmed the diagnosis in 80% of patients, but more recently enhanced computerized tomography and magnetic resonance imaging have been the preferred studies. The operative procedure was either hemilaminectomy or laminectomy with \u00d7 3.5 magnification and fiberoptic lighting. Herniated lumbar discs involved L4\u20135 and L5\u2013S1 with equal frequency (47%). The recurrence rate was 6%, one-third of which developed during the 1st year after operation. The complication rate was 4%; there were no intraoperative vascular or intestinal injuries. The Prolo Functional Economic Outcome Rating Scale was used to measure long-term outcome and the results were compared to those of Pappas,<jats:italic>et al.<\/jats:italic>Patients who did sedentary work and housewives had statistically higher total and economic Prolo scores (p &lt; 0.01) than those who did strenuous work. The majority of patients with the \u201cfailed-back syndrome\u201d had pending legal or Workers' Compensation claims, or were at psychological risk for surgery. In 89% of patients the outcome was good \u2014 defined as a Prolo score of 8 in 10%, 9 in 19%, and 10 in 60%.<\/jats:p>","DOI":"10.3171\/jns.1994.80.3.0415","type":"journal-article","created":{"date-parts":[[2009,5,28]],"date-time":"2009-05-28T14:54:50Z","timestamp":1243522490000},"page":"415-421","source":"Crossref","is-referenced-by-count":235,"title":["A long-term outcome analysis of 984 surgically treated herniated lumbar discs"],"prefix":"10.3171","volume":"80","author":[{"given":"Richard A.","family":"Davis","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1754","reference":[{"key":"b1","first-page":"501","volume":"132","author":"Andersson H","year":"1966","journal-title":"Acta Chir Scand"},{"key":"b2","doi-asserted-by":"publisher","DOI":"10.3171\/jns.1988.69.5.0649"},{"key":"b3","doi-asserted-by":"crossref","first-page":"191","DOI":"10.1097\/00003086-198106000-00032","volume":"157","author":"Burton CV","year":"1981","journal-title":"Clin Orthop"},{"key":"b4","first-page":"2569","volume":"47","author":"Campbell E","year":"1947","journal-title":"NY State J Med"},{"key":"b5","first-page":"139","volume":"22","author":"DePalma AF","year":"1962","journal-title":"Clin Orthop"},{"key":"b6","doi-asserted-by":"publisher","DOI":"10.1097\/00007632-198812000-00015"},{"key":"b7","doi-asserted-by":"crossref","first-page":"1113","DOI":"10.2106\/00004623-198567070-00016","volume":"67","author":"Frymoyer JW","year":"1985","journal-title":"J Bone Joint Surg (Am)"},{"key":"b8","first-page":"116","volume":"1","author":"Garfin SR","year":"1988","journal-title":"J Spinal Disord"},{"key":"b9","doi-asserted-by":"crossref","first-page":"947","DOI":"10.1097\/00007632-198909000-00006","volume":"14","author":"Greenough CG","year":"1989","journal-title":"Spine"},{"key":"b10","doi-asserted-by":"publisher","DOI":"10.1097\/00005373-196103000-00008"},{"key":"b11","doi-asserted-by":"crossref","first-page":"765","DOI":"10.1097\/00007632-198710000-00010","volume":"12","author":"Haddad GH","year":"1987","journal-title":"Spine"},{"key":"b12","doi-asserted-by":"publisher","DOI":"10.3171\/jns.1975.43.6.0727"},{"key":"b13","doi-asserted-by":"crossref","DOI":"10.1007\/978-3-642-92815-4","volume-title":"Lumbaler Bandscheibenvorfall.","author":"Jochheim KA","year":"1961"},{"key":"b14","first-page":"134","volume":"72","author":"Knighton RS","year":"1964","journal-title":"Western J Surg"},{"key":"b15","doi-asserted-by":"publisher","DOI":"10.3171\/jns.1988.69.1.0061"},{"key":"b16","volume-title":"Lumbar Disc Disease.
