Abstract

Introduction The aim of this study was to determine the reliability and accuracy of the tape measurement method (TMI.1) with a nearest reading of 5 mm in assessing leg length discrepancy (LLD) Methods. This was a cross-sectional stud/ conducted on 35 patients with LID and 13 patients without LLD Two blinded surgeons measured the lower limbs from IN anterior supener iliac spine to the medial malleolus using TPAM with a nearest reading of 5 mm Computed tomography (CT) scanograms of the lower limbs of 22 patients were conducted by two blinded radiologists Immolass correlation coefficient (ICC) with 95 percent confidence interval was calculated to assess the interobserver reliadMy of TPAM The accuracy of VIM was assessed by comparison with CT as the gold standard Results The interobserver reliability of LLD measurement using both TPAM and CT scanogram was high. with ICCs of 0 924 and 0971. respectively No significant mean difference on paired sample West was observed for both TPAM and CT scanogram Compared to CT scanogram. TMM had good 3CCUMCy. with an ICC of 0.805 When the mean TP.IM readings by two observers were compared to those................
