INTRODUCTION: The purpose of this study was to investigate the factors causing abnormal deviation of radioulnar carpal joint.
METHOD: Subjects of this research were 90 men and women ranging 19-64 years of adults with normally developed musculoskeletal system. Maximal deviation of each radial and ulnar deviation, and total deviation were produced using a specially designed goniometer. The goniometer was stabilized on the flat table and flexibility of radioulnar joint was measured with forearm pronated. The center of the movement for deviation was determined by the cross-point made by the imaginary axis which passes the center of middle finger and 3rd metacarpal bone, and the halfway point of styloid processes of the radius and the ulna. The center of movement was positioned on the center of goniometer and plastic marker was inserted on the distal phalange of the middle finger and matched with the zero point of the rotation. The subjects relaxed the elbow and tried deviation thru the center of the movement, and the angle of maximum deviation which actively moved was recorded. Each radioulnar deviation was measured twice and the average was recorded. Correlation analysis and t-test were performed for the analysis of 5 independent variables such as age, sex, experience of labor and exercise, experience of fracture and inflammation on the wrist, and major hand. PASW V18.0 statistic program was performed for the analysis and the significance level was p<.05.
RESULTS: The radial and ulnar deviations on each of the independent variables were found to be insignificant except age. Also, total deviation of radius and ulna for the independent variables was found to be significant between major and minor hand. Ulnar deviation and total deviation of right hand were found significant for age and total deviations of major and minor hand were found to have significant interaction effect with age. For major and minor hand, there was a significant difference between having experience and no experience of labor and exercise. For major hand, there was a significant difference between having experience and no experience of fracture and inflammation.
CONCLUSION: Total deviation of minor hand had significantly greater interaction effect with the no experience of labor and exercise. Total deviation of major hand had significantly greater interaction effect with no experience of fracture and inflammation of wrist.
