Abstract
Introduction & Objective: Limb length discrepancy is a common medical problem. There are different radiological methods, rather than clinical methods, each with its own advantages and disadvantages. Materials & Methods: In this study, the patients with the clinical diagnosis of limb length discrepancy were included. At first, they were evaluated clinically and the amount of true limb length discrepancy was detected. Then the results of scanogram were compared with the clinical results. Results: Therefore, 161 patients were included in this study, 97 patients (60%) were male and 64 patients (40%) were female. After the first examination, in 6.1 % of patients the apparent length of two limbs were the same, but in 53.4% of patients the right limb and in 40.5% of patients, the left limb was shorter. With scanogram evaluation, in 56.6% of patients the right limb and in 43.4% of patients the left limb, was shorter. In 22.2% of patients there was no correlation among the side of the short limb and the results of scanogram and clinical examination. Conclusions: This study shows the significance of scanogram in assessment of orthopedic examination and measurement of exact shortness of the limb before any corrective or lengthening procedures.
