Ligamentous stability and joint congruity are prerequisites for a physiological function of the distal radioulnar joint (DRUJ). Impingement of the ulnar head may be caused by a congenital ulna-minus variance or by an iatrogenically excessive ulna shortening osteotomy. This impingement is detected by a positive compression test at the DRUJ. Radius correction osteotomy with shortening and correction of the radial inclination to restore the sigmoid notch may solve the problem by reducing the pressure between both joint partners and by promoting the remodelling of the DRUJ. This technique may restore the distal radioulnar joint and thus prevent the necessity of salvage procedures.
韧带稳定性和关节一致性是桡尺远侧关节（DRUJ）生理功能的先决条件。尺骨头撞击可能由先天性尺骨负变异或医源性尺骨过度短缩截骨术引起。通过DRUJ处的阳性挤压试验可检测到这种撞击。进行桡骨截骨术并缩短和矫正桡骨倾斜度以恢复乙状切迹，可通过降低两个关节面之间的压力并促进DRUJ的重塑来解决该问题。该技术可恢复桡尺远侧关节，从而避免挽救性手术的必要性。
