Closed Reduction and Percutaneous Pinning

Abstract

Percutaneous pinning supplemented with a cast is a cheap, simple, quick and still a popular treatment option for unstable distal radius fractures under given circumstances. Using the AO classification system, unstable both A-, C-1 and C-2 fractures may be suitable for percutaneous pinning. The prerequisites are acceptable reducibility under fluoroscopic view and good purchase in the bone stock. The method has versatility and is suitable for all age groups regardless of gender, but is mostly used for fractures with limited instability and comminution. The most common and recommended method used includes two pins (1.5–1.8 mm) introduced in a crossed fashion respectively through the volar and dorsal radial styloid tip and one pin from the dorsal/ulnar border of the radius. Despite the fact that there is some radial subsidence postoperatively after pinning, this method yields acceptable radiological and satisfactory long-term clinical results, especially in the elderly. Complications after pinning are few, mainly transitory pin infections.
