radiocarpal joint

Objective To study the range and change of stress in normal radiocarpal joint .

目的研究正常桡腕关节内应力分布及其变化规律。

Objective To investigate the impact of dorsally angulated malunited distal radius fractures on the stability of the radiocarpal joint .

目的研究桡骨远端骨折背侧成角畸形对桡腕关节稳定性的影响。

Lymphangion was displayed , the palm side of the radiocarpal joint showed a winding thin line on lateral film ;

淋巴管显影，侧位相于掌侧面可见弯曲的细线样影像；

Conclusion : Contacting area and pressure to the navicular and lunare show significant changes when the radiocarpal joint angular reached more than 10 degrees and it leads to significant influence on the wrist joint .

结论：桡腕关节面背倾10°以上时，桡偏10°以上时，舟骨和月骨的接触面积及接触应力有显著变化，影响腕关节功能。

Conclusions : It appears that the most significant effect on contact stress of the radiocarpal joint occurs with a 4mm radial shortening ( RS ) or more , and lead to significantly effect on wrist joint .

结论：桡骨远端骨折短缩4mm以上时，接触应力有显著变化，影响腕关节功能。

Results All the grafted bone flap in the 15 cases healed , with abundant blood supply . The callus grew quickly after operation ; the excellent function of the radiocarpal joint was restored 10 to 12 weeks postoperatively .

结果临床用骨瓣治疗舟骨骨折15例，骨瓣血供丰富，术后10～12周愈合，腕关节功能恢复正常。
