Combined internal and external fixation of distal radius fractures is used most commonly to treat injuries with joint surface or metaphyseal comminution. External fixation aids reduction intraoperatively and facilitates arthroscopic, per-cutaneous, or open manipulation of the fracture. Internal fixation maintains precise reduction of critical anatomy, principally the contour and orientation of the articular surface. Postoperatively the fixator functions as a neutralization device, preventing fracture collapse and decreasing the biomechanical demands on the internal fixation hardware. The combined technique exploits the benefits of both forms of fixation, allowing each to be used to full advantage in the treatment of complex distal radius fractures.
桡骨远端骨折的内外联合固定最常用于治疗伴有关节面或干骺端粉碎的损伤。外固定有助于术中复位,并便于对骨折进行关节镜、经皮或切开操作。内固定可维持关键解剖结构的精确复位,主要是关节面的轮廓和方向。术后,固定器起到中和装置的作用,防止骨折塌陷并降低对内固定器械的生物力学要求。联合技术利用了两种固定方式的优点,使每种方式在治疗复杂桡骨远端骨折时都能充分发挥优势。
