During a period of forty-two years, twenty patients who had a post-traumatic proximal radio-ulnar synostosis were treated by excision of the area of synostosis and various concurrent procedures in an attempt to restore rotation of the forearm. The time from injury to operation averaged eighteen months, and the postoperative follow-up averaged forty months. Results were graded on the basis of improvement in the arc of rotation of the forearm. After excision of the area of synostosis in the fifteen patients for whom data were available, the intraoperative arc of passive rotation averaged 121 degrees. At the most recent follow-up, the range of active rotation averaged 55 degrees for all twenty patients. Four patients had an excellent result; three, good; four, fair; and nine, poor. The outcome of this type of surgical treatment varies, but roughly half of the patients can be benefited.
在42年的时间里，20例创伤后近端桡尺关节融合患者接受了融合部位切除及各种同期手术，试图恢复前臂的旋转功能。受伤至手术的平均时间为18个月，术后平均随访40个月。结果根据前臂旋转弧度的改善情况进行分级。在有数据可查的15例患者中，切除融合部位后，术中被动旋转弧度平均为121度。在最近一次随访时，20例患者的主动旋转范围平均为55度。4例结果为优；3例为良；4例为中；9例为差。这类手术治疗的结果各不相同，但大约一半的患者能从中受益。
