Ransford环在枕颈融合术中的应用

Ransford loop fixation for the treatment of occipitocervical stability

目的 评价Ransford环在枕颈融合术中的固定作用。方法 9例陈旧性寰枢椎骨折脱位 ,5例枕颈区畸形行后路枕颈减压 ,髂骨植骨 ,用自制Ransford环颅骨下和椎板下钢丝固定 ,术后X线片观察枕颈植骨融合。结果 1 3例随访 6个月～ 4年 ,神经功能明显恢复 ,1 2例枕颈区骨性融合。

Objective To evaluate the value of fixation during bone fusion for patients undergone posterior occipitocervical decompression and Ransford loop fixation Methods 9 cases of old odontoid fracture associated with atlantoaxial dislocation,five cases of congenital malformation of occipitocervical junction underwent occipitocervical decompression, autograft bone and posterior occipitocervical stabilization with use of a Ransford loop was affixed by sublaminar wires.Results 13 patients were followed up from 6 to 48 months.Bone fusion was seen in 12 patients and non union with the graft broken in one case.All patients had the nerve function significantly improved.Conclusion Ransford loop has the advantage over bone grafting of providing rigid stabiblization and contributing to eventual bone fusion. <
