摘　　要：目的综述近排腕骨间不稳的生物力学研究进展。方法查阅国内外有关近排腕骨间不稳的研究文献,从基础生物力学和临床生物力学两方面入手,分析周围软组织维持其稳定的生物机制,并总结其稳定性修复与功能重建的方法。结果近排腕骨间的肌肉与韧带对其稳定性起决定性作用,其生物力学作用机制已达成共识,但三角纤维软骨复合体受损后周围软组织对远端尺桡关节稳定性的作用机制、舟月关节韧带的生物力学作用机制仍存在争议。此外,生物力学研究中近排腕骨间不稳重建方法尚无统一标准,影响了其指导临床实践的作用。结论近排腕骨间不稳在相关肌肉、韧带的基础生物力学研究以及修复重建的临床生物力学研究方面均已取得一定进展,但还不全面,仍需在腕骨本身形态、邻近关节面形态(尤其是桡骨远端的形态)、远端腕骨对近端腕骨产生的压力等方面进行更深入研究。Objective To review the research progress of the biomechanics of proximal row carpal instability（IPRC）. Methods The related literature concerning IPRC was extensively reviewed. The biomechanical mechanism of the surrounding soft tissue in maintaining the stability of the proximal row carpal（PRC） was analyzed,and the methods to repair or reconstruct the stability and function of the PRC were summarized from two aspects including basic biomechanics and clinical biomechanics. Results The muscles and ligaments of the PRC are critical to its stability. Most scholars have reached a consensus about biomechanical mechanism of the PRC,but there are still controversial conclusions on the biomechanics mechanism of the surrounding soft tissue to stability of distal radioulnar joint when the triangular fibrocartilage complex are damaged and the biomechanics mechanism of the scapholunate ligament. At present,there is no unified standard about the methods to repair or reconstruct the stability and function of the PRC. So,it is difficult for clinical practice. Conclusion Some strides have been made in the basic biomechanical study on muscle and ligament and clinical biomechanical study on the methods to repair or reconstruct the stability and function of PRC,but it will be needed to further study the morphology of carpal articular surface and the adjacent articular surface,the pressure of distal carpals to proximal carpal and so on.
