- 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 π-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°±6.9 and 33.1°±6.8)(p<0.05). 1-2 IMA in observer A was not regarded as reliable (16.9°±2.8 and 17.1°±2.8)(p>0.05). In the results of observer B, HVAs were measured as 35.7°±7.6 and 36.2°±7.7, and were not reliable (p>0.05). 1-2 IMA in observer B was not reliable as well (17.0°±0.8 and 20.8°±1.5)(p>0.05). In the interobservers’ measurements, the first and the second results of HVA were 3.2°±3.6 and 3.1°±3.1, reliable within the 95% confidence interval (p<0.05). 1-2 IMAs were 0.1°±1.9 and 3.73°±1.3, which were not reliable (p>0.05).
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.
