The Roger Anderson external fixator was used in the treatment of unstable fractures of the distal radius in 52 patients, and the results evaluated after a follow-up averaging 58 months. The indications for its use were failure to maintain adequate closed reduction using plaster, and instability of the fracture as determined by the initial radiographs. Our radiological criteria for instability included dorsal angulation of more than 20 degrees, fractures involving the joint, radial shortening of more than 10 mm, and severe dorsal comminution. Using the Lucas modification of the Sarmiento demerit point-rating system, we found that 46 patients (89%) had good or excellent results and six (11%) were classified as fair. There were no poor results. Seven patients (14%) developed complications. None of these affected the long-term results except in one elderly woman where the pins loosened and had to be removed.
采用罗杰·安德森外固定器治疗52例桡骨远端不稳定骨折，平均随访58个月后评估结果。使用该外固定器的指征为石膏固定无法维持充分的闭合复位，以及根据初始X线片确定的骨折不稳定。我们的不稳定放射学标准包括背侧成角超过20度、累及关节的骨折、桡骨缩短超过10毫米以及严重的背侧粉碎。采用卢卡斯改良的萨米恩托缺点评分系统，我们发现46例患者（89%）结果为良好或优秀，6例（11%）为一般。无结果差的情况。7例患者（14%）出现并发症。除1例老年女性因钢针松动必须取出外，这些并发症均未影响长期结果。
