One hundred and twenty-one displaced Colles' fractures were assessed radiographically until union. An acute loss of position occurred during the first week of splintage, necessitating re-manipulation in six fractures. In the remaining 115 fractures whose position had been retained after one week, chronic instability led to a mean increase of 8.22 degrees dorsal angulation, a mean loss of 5.61 degrees radial angle, and 3.26 mm radial shortening. The extent to which the chronic collapse of radial angle and length occurred was determined solely by the initial deformity and was not related to either intraarticular involvement or the presence of radiographically visible comminution. However, the absence of radiographically visible comminution of the dorsal radius did confer stability against mal-union in dorsal angulation.
对121例移位的Colles骨折进行了影像学评估直至愈合。在夹板固定的第一周内发生了急性位置丢失，6例骨折需要再次手法复位。在其余115例骨折中，其位置在一周后得以保留，但慢性不稳定导致平均背侧成角增加8.22度，平均桡骨角丢失5.61度，桡骨缩短3.26毫米。桡骨角和长度的慢性塌陷程度仅由初始畸形决定，与关节内受累情况或影像学可见的粉碎性骨折均无关。然而，桡骨背侧无影像学可见的粉碎性骨折确实有助于防止背侧成角畸形愈合。
