چکیده مقاله:

 Abstract 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. 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. 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). 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.

Indeed, as the great evolutionist Theodosius Dobzhansky asserted in 1973 in an address to the American Association of Biology Teachers, ‘‘Nothing in bi...

One Hundred Fifty Years of Change in Forest Bird Breeding Habitat: Estimates of Species Distributions

Evaluating bird population trends requires baseline data. In North America the earliest population data available are those from the late 1960s. Forest conditions in the northern Great Lake states (U.S.A.), however, have undergone succession since the region was originally cut over around the turn of the twentieth century, and it is expected that bird populations have undergone concomitant chan...

Fifty years--a radiographic retrospect.

ONE DAY Dr. R. S.

The 'Royal' is so known to the entire population of Belfast and so I will continue to call it in this paper. The X-ray department a...

One hundred and fifty years of sprint and distance running - Past trends and future prospects.
