Application of Apofix interlaminar clamp to atlantoaxial instability and dislocation / 重庆医科大学学报

ABSTRACT

Objective:To observe the efficacy and the complications of Apofix interlaminar clamp in the treatment of atlantoaxial instability and dislocation,and to study the causes of these complications and the preventive measures against them. Methods:17 patients with atlantoaxial instability or dislocation were treated with posterior atlantoaxial fusion and Apofix interlaminar clamp fixation.Results:One case of atlantoaxial dislocation was dead and another dislocation case was redislocated one week after the operation,while the others were followed up for 3 to 24 months and all recovered well.Conclusion:It is simple to apply Apofix interlaminar clamp.The clamp can provide reliable stability for the atlantoaxial segment,and is useful for the fusion of the bone implant.Correct indications are playing an important role in avoiding the complications.
