Abstract:
Objective To observe the influence of preoperatively physical curvature abnormality and different fixation systems on postoperative axial symptom (PAS) and union rate of hinge groove after unilateral expansive laminoplasty for the patient with cervical spondylotic myelopathy (CSM).Methods The study reviewed 106 CSM patients who underwent unilateral laminoplasty supplemented by lateral mass or pedicle screw/rod fixation with a minimum of 36 months of follow-up.According to being complicated with physical curvature abnormality or not,the incidence,initial onset,severity,duration of PAS and union rate of hinge groove at postoperative 6 months were respectively compared to analyze the influences of two internal methods on the features of PAS.Results For 50 cases without physical curvature abnormality,fusion rates of hinge groove in pedicle placement group was higher than that in lateral mass fixation group,the P value reached statistical difference (t=142.2,P=0.032).Duration of PAS in pedicle group was shorter than that in lateral mass group,the difference reached statistic significance (t=147.2,P=0.019).For 56 cases of with physical curvature abnormality,incidence of PAS in pedicle group presented was lower than that in lateral mass group,the difference achieved statistic significance (x2=3.89,P=-0.042).Conclusion Whether concomitant with physical curvature abnormality or not,pedicle fixation would be beneficial to promoting bony fusion of hinge groove,shortening duration of PAS and reducing incidence of PAS in contrast to lateral mass fixation to some extent after unilateral laminoplasty for treating CSM patients.
