An ununited scaphoid fracture whose proximal fragment is small, sclerotic, fragmented, or badly deformed is usually not suitable for bone-grafting. We treated twenty-one such patients by excision of the small proximal fragment through a volar incision and the insertion of a hand-carved silicone-rubber spacer. After surgery, twenty patients (95 per cent) were able to return to work and engage in strenuous activities, including sports. Pain was significantly relieved, although wrist motions and grip were only minimally improved. Preoperative and postoperative comparative measurements of carpal collapse and translation showed only insignificant changes after this procedure.
舟状骨骨折不愈合且近端骨折块较小、硬化、碎裂或严重变形时，通常不适合进行骨移植。我们通过掌侧切口切除小的近端骨折块并植入手工雕刻的硅橡胶间隔物，治疗了21例此类患者。术后，20例患者（95%）能够重返工作岗位并参加剧烈活动，包括体育运动。疼痛明显缓解，尽管腕关节活动度和握力仅略有改善。术前和术后对腕骨塌陷及移位的对比测量显示，该手术后仅有不显著的变化。
