Seventeen patients who had a closed fracture of the radial head that was not associated with a dislocation of the elbow or another injury were evaluated eight to forty-six years after resection of the radial head. Few patients complained of even mild, intermittent pain. The ranges of motion of the wrist and elbow were nearly normal, but pronation and supination were decreased by an average of 7 and 15 degrees, respectively. Cybex testing showed losses of strength in pronation and supination of approximately 5 and 11 per cent, respectively. The ulnar variance became increasingly positive by an average of approximately two millimeters, and cubitus valgus increased an average of 9 degrees. These excellent results did not appear to deteriorate over time. In one patient a radio-ulnar synostosis developed.
17例桡骨头闭合性骨折且未合并肘关节脱位或其他损伤的患者在桡骨头切除术后8至46年接受了评估。很少有患者抱怨哪怕是轻微的间歇性疼痛。腕关节和肘关节的活动范围几乎正常，但旋前和旋后分别平均减少了7度和15度。Cybex测试显示旋前和旋后力量分别损失了约5%和11%。尺骨变异平均增加约2毫米，逐渐变得更加正向，肘外翻平均增加9度。这些优异的结果似乎并未随时间恶化。有1例患者发生了桡尺骨融合。
