[Fate of the calcium-dense proximal fragment in scaphoid fracture].
A cohort study with retrolective and prolective collection of data was carried out 49 of 99 patients with scaphoid fractures, initially treated by plaster cast immobilization and having developed a proximal fragment with increased bone density were studied. More than half of these patients had a good or excellent result according to the modified score of Green and O'Brien 29 of 49 proximal fragments with increased bone density returned to normal density: 45 of 49 showed bony union, and 35 of 49 showed no signs of posttraumatic arthrosis. The appearance of stripes with increased bone density in plain X-rays indicated a problem in the process of fracture healing; the clinical interpretation, however, was difficult. Four patients were treated by percutaneous canulated screw (Streli). These fractures showed bony union, the fragment with increased bone density returned to normal in three of four patients. All of these patients had some remaining clinical problems.
