It has been reported that the distal interosseous membrane (DIOM) of the forearm constrains the dorsal dislocation of the distal radius. A residual ulnar translation deformity of the radial shaft in distal radius fractures has the potential to cause distal radioulnar joint (DRUJ) instability when triangular fibrocartilage complex (TFCC) injury is also present, because it may result in detensioning of the DIOM. Correction of ulnar translation of the radial shaft is critical because it restores DIOM tension, which then firmly holds the ulnar head in the concavity of the sigmoid notch.
据报道，前臂的远侧骨间膜（DIOM）可限制桡骨远端的背侧脱位。当桡骨远端骨折合并三角纤维软骨复合体（TFCC）损伤时，桡骨干的尺侧残余移位畸形有可能导致下尺桡关节（DRUJ）不稳定，因为这可能会导致DIOM松弛。纠正桡骨干的尺侧移位至关重要，因为它可恢复DIOM的张力，进而将尺骨头稳固地固定在乙状切迹的凹面内。
