Eight elbows in six patients who had had excision of the radial head for congenital dislocation were evaluated an average of seven years postoperatively. The average age of the patients at the time of the excision was thirteen years (range, ten to 15.5 years). The dislocation was posterior in five elbows and posterolateral in three. The over-all increase in the arc of flexion-extension postoperatively compared with preoperatively was 11 degrees (p greater than 0.1): The over-all increase in the arc of rotation was significant at 53 degrees (p less than 0.002). Pain in the elbow had decreased compared with preoperatively, but all patients had minor pain in the wrist. The result was rated good in five elbows, fair in two, and poor in one. One patient had a repeat excision of the radial head after it re-formed, and this was the reason for the poor result. All patients were satisfied with the outcome of the operation. Contrary to previously published data, excision of the radial head for congenital dislocation resulted in an increased range of motion and a decrease in pain in the elbow in our patients.
对6例因先天性脱位而行桡骨头切除术的患者的8个肘关节进行了评估，平均术后7年。切除时患者的平均年龄为13岁（范围为10至15.5岁）。5个肘关节的脱位为后方脱位，3个为后外侧脱位。与术前相比，术后屈伸弧的总体增加为11度（p大于0.1）：旋转弧的总体增加显著，为53度（p小于0.002）。与术前相比，肘部疼痛有所减轻，但所有患者手腕均有轻微疼痛。5个肘关节的结果评为良好，2个为一般，1个为差。1例患者在桡骨头重新形成后再次进行了切除，这是结果差的原因。所有患者对手术结果均满意。与先前发表的数据相反，在我们的患者中，因先天性脱位而行桡骨头切除术导致肘关节活动范围增加和疼痛减轻。
