尺骨茎突骨折与下尺桡关节稳定性关系的有限元分析

The Relationship between the Ulnar Styloid Fracture and Distal Radioulnar Joint Stability : A Finite Element Study

方法：将30侧成人上肢标本，以尺骨茎突为观测标志点进行显微解剖。

METHODS : Samples of lateral upper limbs of 30 adults were dissected as the pivot point of styloid process of ulna with microscope .

结论桡骨远端骨折的关节面不完整、桡骨明显缩短、关节面背倾和伴尺骨茎突骨折对腕不稳定例发生及程度有显著影响。

Conclusions Joint integrity , radial shortening , dorsal tilt of the joint surface and ulnar styloid fractures have significant effect on incidence and severity of carpal instability .

结果：研究表明腕关节盘位于腕关节的特殊位置，其尺侧附着于尺骨茎突和尺骨茎突陷窝两部分，并和桡尺远端关节侧副韧带存在密切关系。

Results : The study showed that the TFC located in a very special part of the wrist and had intimate relations with the ulnar styloid process and recess .

结论前臂于旋前位时，肱骨外上髁至尺骨茎突连线近端7/10可作为桡神经深支的体表投影；

Conclusion With the forearm being pronated , the proximal 7 / 10 of the line between the LHE and the SPU can be considered as the projection on body surface of the deep branch of the radial nerve .
