We reviewed 10 patients with symptomatic malunion of a carpal scaphoid fracture. All had displacement with dorsiflexed intercalated segment instability, and suffered from pain, restricted range of movement at the wrist and decreased grip strength. The restriction of flexion-extension and the decreased grip strength correlated with the severity of the DISI deformity. Seven patients had a corrective osteotomy, using an anterior wedge-shape bone graft with internal fixation by Herbert screw, and all had satisfactory results. We believe that symptoms associated with scaphoid malunion are related to consequent carpal deformity.
我们回顾了10例腕舟骨骨折症状性骨不连患者。所有患者均有移位并伴有背伸插入节段不稳定，且存在疼痛、腕关节活动范围受限和握力下降的情况。屈伸受限和握力下降与背伸插入节段不稳定（DISI）畸形的严重程度相关。7例患者接受了矫正截骨术，采用前路楔形植骨并用Herbert螺钉内固定，所有患者均取得了满意的效果。我们认为，舟骨骨不连相关症状与随之而来的腕骨畸形有关。
