In a prospective study, 204 consecutive patients with displaced Colles' fractures had closed reduction then plaster immobilisation. Three different positions of the wrist in plaster were randomly allocated: palmar flexion, neutral and dorsiflexion. The results in the three groups were compared. Fractures immobilised with the wrist in dorsiflexion showed the lowest incidence of redisplacement, especially of dorsal tilt, and had the best early functional results. Immobilisation of the wrist in palmar flexion has a detrimental effect on hand function; it is suggested that it is also one of the main causes for redisplacement of the fracture. This is discussed in relation to the functional anatomy of the wrist and the mechanics of plaster fixation.
在一项前瞻性研究中，204例连续的Colles骨折移位患者接受了闭合复位，然后进行石膏固定。石膏固定时手腕的三种不同位置被随机分配：掌屈、中立位和背屈。比较了三组的结果。手腕背屈位固定的骨折再移位发生率最低，尤其是背侧倾斜，并且早期功能结果最佳。手腕掌屈位固定对手部功能有不利影响；有人认为这也是骨折再移位的主要原因之一。结合手腕的功能解剖和石膏固定力学对此进行了讨论。
