en Radiographic indices in one hundred fifty normal Iranian wrists Orthopedic Surgery Orthopedic Surgery Original Research Original Research Abstract<o:p /> Background: Radiography is the most widely available imaging modality. Precise evaluations of wrist x-ray can help diagnosis and evaluate the prognosis of many wrist disorders.<o:p /> Methods: We measured length, angles and indices in 150 posteroanterior and lateral wrist x-rays to determine normal dimensions and variations according to age and sex. All x-rays were made with standard exposure, with the wrist and forearm in a neutral position.<o:p /> Results: The average carpal height ratio was 0.52±0.03 with the Youm method and 1.5±0.09 with the Nattrass method. Mean ulnar variance was +0.99±1.6 mm and mean radial inclination was 25±4 degrees. The average radial tilt was 10±5.1 degrees. Mean scapholunate angle was 50±8.4 degrees (normal range 40 -60).<o:p /> Conclusion: Carpal height, third metacarpal and capitate length were smaller in women than in men. There was a significant positive relationship between all dimensions. Our data base may be used to follow-up in conditions such as carpal instability, osteoarthritis and osteonecrosis, as well as for clinical research.<o:p /> Wrist measurements, Wrist radiography, Wrist indices. 132 139 http://mjiri.iums.ac.ir/browse.php?a_code=A-10-1-318&slc_lang=en&sid=1 Davood Jafari djafari@tums.ac.ir 20031947532846005758 20031947532846005758 No Department of Hand Surgery, Shafa Hospital, Tehran University of Medical Sciences, Tehran, Iran.
