Three operative procedures were used for discectomy: unilateral interlaminar bilateral interlaminar and bilateral laminectomy. An objective method of assessing outcome that would not depend on the procedures, the prolo functional-economic outcome rating scale used to evaluate patients. Most patients had good outcome. The patient with non-industrial injuries had better had good outcome. The patient with non-industrial injuries had better outcome. The prolo scale appears to be a useful tool for comparing different procedures more objectively and for comparing the outcome across series.</span></font></font>http://jrms.mui.ac.ir/index.php/jrms/article/view/2950
