Nineteen consecutive patients who had a symptomatic pseudarthrosis after a failed anterior cervical arthrodesis were treated by a posterior nerve-root decompression and arthrodesis. The indications for the operation were radiculopathy in the absence of myelopathy and evidence of a pseudarthrosis on lateral flexion and extension radiographs. The average duration of follow-up was forty-four months (range, twenty-four to fifty-four months). A solid fusion was achieved in all patients, and the radiculopathy was relieved in all but one. The motor weakness that had been present in four patients preoperatively resolved completely.
19例连续的患者，在颈椎前路融合术失败后出现有症状的假关节，接受了后路神经根减压及融合术治疗。手术指征为无脊髓病的神经根病以及侧屈和伸展位X线片上有假关节的证据。平均随访时间为44个月（范围24至54个月）。所有患者均实现了牢固融合，除1例患者外，其余患者的神经根病均得到缓解。术前4例患者存在的运动无力完全消失。
