A Radiological Study of Normal Wrist in Korean People / 대한정형외과학회잡지

ABSTRACT

The carpal injury is difficult to diagnose due to anatomical complexity and the like. So, in order to get radiological knowledge of normal wrist, the authors measured the values which will be described on the wrist PA and lateral roengenogram obtained from 440 normal wrists(male 188 cases, female 252 cases) in randomly selected patients. The following results were obtained. l. Ulnar variance(mm±standard deviation) Total 1.1±1.2 negative variance 9.3%, positive variance 56.1%, 2. Scapholunate Gap(mm±standard deviation) Total 0.4±0.7, 3. Ulnar Tilt(degrees±standard deviation) Total 23.6±5.3, 4. Volar Tilt, 5. Carpal height rstio Total 0.52±0.05 male 0.53±0.04 female 0.51±0.05 Total 13.1±5.9, 6. Carpal ulnsr distance ratio Total 0.05±0.05, 7. Scapholunate Angle Total 49.9'±10.1', 8. Capitatolunate Angle Total 17.5'±10.0', 9. Radiolunate Angle Total 8.8'±6.7', 10. Carpal width ratio Total 0.72±0.08 11. Carpal thickness ratio Total 0.49±0.07.
