A retrospective study was undertaken of twenty patients with a Mason type-II and sixteen patients with a Mason type-III closed fracture of the radial head who had excision of the radial head. The average length of follow-up was 16.4 years (range, three to twenty-seven years) and the average age of the patients at operation was forty-two years (range, eighteen to seventy-five years). Thirty-one patients (86 per cent) were satisfied with the results, and thirty-four (94 per cent) returned to their preoperative occupations. Only three patients lost 30 degrees or more of flexion of the elbow or of pronation or supination of the forearm. A measurable proximal migration of the radius of more than one millimeter was found in eight patients (22 per cent), but no harmful effects of this were found. All of the patients showed osteoarthritic changes on roentgenograms of the elbow that had been operated on, but these did not affect the functional scoring. According to the functional classification that we used, thirty-three (92 per cent) of the patients were able to function satisfactorily in activities of daily living and only three were not. We concluded that if, for any reason, operative treatment is undertaken for these fractures, good functional results can be expected. Nevertheless, because the results of non-operative treatment of Mason type-II fractures, as reported in the literature, have been almost identical to ours, we have adopted a non-operative approach in the last few years.
对20例接受桡骨头切除术的Mason II型闭合性桡骨头骨折患者和16例Mason III型闭合性桡骨头骨折患者进行了回顾性研究。平均随访时间为16.4年（范围3至27年），患者手术时的平均年龄为42岁（范围18至75岁）。31例患者（86%）对结果满意，34例患者（94%）恢复了术前工作。只有3例患者肘关节屈曲或前臂旋前、旋后丧失30度或更多。8例患者（22%）出现桡骨近端超过1毫米的可测量移位，但未发现由此产生的有害影响。所有接受手术的患者肘部X线片均显示骨关节炎改变，但这些改变不影响功能评分。根据我们采用的功能分类，33例患者（92%）在日常生活活动中功能良好，只有3例患者功能不佳。我们得出结论，对于这些骨折，如果出于任何原因进行手术治疗，可以预期获得良好的功能结果。然而，由于文献报道的Mason II型骨折非手术治疗结果与我们的几乎相同，我们在过去几年中采用了非手术治疗方法。
