Abstract
-
PURPOSE: To study the reliability of intra- and interobserver reliability in angular measurement of hallux valgus deformity by assessing hallux valgus angle (HVA) and the 1st to 2nd intermetatarsal angle (1-2 IMA) through using computerized system.
MATERIALS AND METHODS
20 cases of moderate to severe hallux valgus patients were included in this study. With the standing anteroposterior view of foot, the HVA and 1-2 IMA were calculated by computerized measurement system of Infinity cooperation, called phi-view, with its software tools. Using the statistical software program, SPSS (version 12th), we interpreted the results which were measured by two independent observers.
RESULTS
In the intraobserver measurement, the HVA of observer A showed reliability (32.5 degrees +/-6.9 and 33.1 degrees +/-6.8)(p<0.05). 1-2 IMA in observer A was not regarded as reliable (16.9 degrees +/-2.8 and 17.1 degrees +/-2.8)(p>005). In the results of observer B, HVAs were measured as 35.7 degrees +/-7.6 and 36.2 degrees +/-7.7, and were not reliable (p>005). 1-2 IMA in observer B was not reliable as well (17.0 degrees +/-0.8 and 20.8 degrees +/-1.5)(p>005). In the interobservers' measurements, the first and the second results of HVA were 3.2 degrees +/-3.6 and 3.1 degrees +/-3.1, reliable within the 95% confidence interval (p<0.05). 1-2 IMAs were 0.1 degrees +/-1.9 and 3.73 degrees +/-1.3, which were not reliable (p>005).
CONCLUSION
In the angular measurement of the hallux valgus by computerized system, the HVA and 1-2 IMA showed less error range in the interobserver's results, compared with the previous studies about the manual measurement. However, our results failed to show the statistical reliability of intra- and interobserver's measuring. Therefore, even the computerized angular measurements in the severity of hallux valgus require development of the measuring methods and software tools.
