Treatment-related complications in the external fixation of complex distal radius fractures may be diminished by the insertion of 4-mm, self-tapping half-pins after predrilling. The pins are placed proximally in the radius and distally through six cortices of the second and third metacarpals. An adaptable fixation device that allows reduction after pin insertion and assembly is recommended. It must allow enough mobility to completely reduce a very unstable fracture after its application. A limited open surgical approach allows direct visualization of the bone where the fixator pins will be placed, as well as central insertion of the pins. It avoids eccentric drill placement, open section defects, redrilling, and damage to soft-tissue structures.
通过在预钻孔后插入4毫米的自攻半针，可减少复杂桡骨远端骨折外固定中与治疗相关的并发症。这些针近端置于桡骨，远端穿过第二和第三掌骨的六个皮质。建议使用一种可适配的固定装置，该装置允许在插入针并组装后进行复位。它必须具有足够的灵活性，以便在应用后能完全复位非常不稳定的骨折。有限的开放手术入路可直接观察到将放置固定针的骨骼部位，以及针的中心插入。它可避免钻孔偏心、开放段缺损、重新钻孔以及对软组织结构的损伤。
