Objective:
Scheuermann’s disease is diagnosed radiologically. Radiological measurements play role both in diagnosis of the disease and in the planning of the treatment. In this study, the evaluation of the intra-observer and inter-observer reliability of the radiological measurements used in Scheuermann disease was aimed.
Material and Methods:
Ten patients with Scheuermann disease diagnosed by both practitioners were evaluated. The wedging angle on the most wedged vertebra and the kyphosis angle of the patients were measured by two different observers two times for 3 weeks apart.
Results:
The correlation coefficients for intra-observer reliability in Scheuermann’s disease ranged % 84 - % 92.7 in the measurement of kyphosis angle and it was ranged % 70,8 - % 90,5 in the measurement of the wedging angle. The correlation coefficients for interobserver reliability were detected 87.9 % and 89.7 % for kyphosis angle measurements; and 82% and 68.1% for the measurement of wedging angle.
Conclusion:
Radiological measurements used in Scheuermann’s disease have high intra-observer and interobserver reliability.
