Ransford环在枕颈融合术中的应用

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接脱位，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 13例随访6个月-4年，神经功能明显恢复，12例枕颈区骨性融合。结论 Ransford环在枕颈融合术中能提供较强的固定作用。

Ransford loop fixation for the treatment of occipitocervical stability

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. <
