Abstract
- OBJECTIVE: This study aimed to compare 2 methods of ulnar variance (UV) measurement (the perpendicular method and the circular method) and to determine whether UV changed based on the demographic characteristics (sex and age). METHODS: UV was measured on bilateral wrist radiographs of 124 patients (62 men, 62 women; mean age=48.5 years; range=18–79 years) who had no history of trauma, congenital wrist anomaly, previous wrist surgery, and wrist osteoarthritis by a single radiologist with 4 years of experience. All measurements were made on standardized radiographic images using 2 methods: the perpendicular method and the circular method. All the patients were then divided into groups based on sex and age, and the study population was determined by selecting a similar number of patients for each sex and age group. RESULTS: The mean UV of the right and left wrists was measured as 0.33 (range=−4.3 to 5.7) mm by the perpendicular method and as 0.034 (range=−5 to 5.7) mm by the circular method. A significant difference was determined between the 2 measurement methods (p
