A rare case of trans-triquetral dorsal perilunate dislocation is described. It differs from the Mayfield and Johnson theory of progressive perilunar instability in greater arc injuries which states that the injury passes from the radial to the ulnar carpal bones and soft tissues in stages. This injury supports the concept of a reverse greater arc injury from ulnar to radial being possible with the radial carpal bones being spared in some cases.
本文描述了一例罕见的经三角骨背侧月骨周围脱位。它与梅菲尔德和约翰逊关于大弧损伤中月骨周围渐进性不稳定的理论不同，该理论认为损伤是从桡侧腕骨向尺侧腕骨及软组织逐步发展的。这种损伤支持了一种反向大弧损伤的概念，即从尺侧向桡侧的损伤是可能的，在某些情况下桡侧腕骨可免于损伤。
