桡骨远端骨折畸形愈合对下尺桡关节的影响

Impact of distal radius fracture malunion on distal radioulnar joint

畸形愈合是桡骨远端骨折后较为常见的并发症,可累及桡腕关节、尺腕关节和下尺桡关节等。桡骨远端畸形愈合可对下尺桡关节的生物力学和临床预后等方面产生一定的影响,可有疼痛、前臂旋转受限、下尺桡不稳定、下尺桡关节炎等临床表现。既往国内外关于桡骨远端骨折畸形愈合的文献中,较多的学者对桡腕关节和尺腕关节进行了研究,而对下尺桡关节的研究相对较少。本文综述了近年来桡骨远端骨折畸形愈合对下尺桡关节影响的相关研究进展,为临床诊治及进一步研究提供参考。

Malunion is a common complication after distal radius fracture,which involves the radiocarpal joint,ulnocarpal joint,and distal radioulnar joint.This malunion does have a certain impact on the biomechanics and clinical prognosis of the distal radioulnar joint with clinical manifestations such as pain,limited rotation of the forearm,instability of the distal radioulnar joint and distal radioulnar arthri⁃tis.In the previous literature on the malunion of distal radius fractures at home and abroad,many scholars have focused on the radiocarpal joint and the ulnocarpal joint,while there is a rare research on the distal radioulnar joint.This article reviews the recent research progress on the effects of distal radius fracture malunion on the distal radioulnar joint,to provide a reference for clinical prevention,treatment,and further research.
