Operative treatment for non-union of the carpal scaphoid bone with a small proximal fragment often presents some difficulties. A complete Silastic carpal scaphoid replacement does not always fit well because the shape and dimensions of the implant differ from the natural carpal scaphoid bone. The proximal fragment looks more like the lunate bone and so a Silastic carpal lunate implant may be used to replace the proximal fragment of the scaphoid while the well preserved distal fragment remains in place. This prevents disturbance of the intercarpal joint composition and improves stability of the base of the thumb. Five patients have been treated in this manner. The procedure is described in detail.
对于近端骨块较小的腕舟骨不愈合，手术治疗常常存在一些困难。完整的硅橡胶腕舟骨假体并不总是能很好地适配，因为假体的形状和尺寸与天然腕舟骨不同。近端骨块看起来更像月骨，因此可以使用硅橡胶腕月骨假体来替代舟骨的近端骨块，而保存良好的远端骨块则保留原位。这可防止腕骨间关节结构受到干扰，并提高拇指基部的稳定性。已有5例患者接受了这种治疗方式。本文将详细描述该手术过程。
