Abstract:
The wrist, or carpus, is a deformable anatomic entity composed of 8 small carpal bones (scaphoid, lunate, triquetrum, pisiform, hamate, capitate, trapezium and trapezoid) and the surrounding soft-tissue structures. We should get radiological knowledge of normal wrist in order to identify pathology of that. So we measured the several values on AP, PA and lateral roentgenograms of 228 normal wrist(male : 124 cases, femal: 104 cases). The following results were obtained: 1. Scapholunate gap : 1.4±0.5mm 2. Ulnar variance : 1.3 ±1.7mm, Positive variance … 59.7%, Neutral variance … 25.4% 3. Carpal height ratio : 0.543 ±0.078 4. Carpal ulner distance ratio : 0.32 ±0.04 5. Scapholunate angle : 45.8 ± 8.7° 6. Capitatolunate angle : 19.3 ± 8.2° 7. Radiolunate angle : 8.9 ± 4.7° 8. Ulnar tilt: 23.5 ± 3.3° 9. Volar tilt: 12.0 ± 4.7°
