Abstract:
Objective To study the effect of posterior unilateral open-door laminoplasty which anchor the different segments of patients on neurological function improvement rate,cervical range of motion,axial symptoms and complications.Methods From June 2009 to April 2013,86 patients with cervical spondylotic myelopathy received posterior unilateral open-door laminoplasty by anchoring were selected.The open segments were C3-7.They were divided into two groups according to the anchor segments.Group A of 48 patients,anchor segments was C3-7,using 5 anchoring nails.Group B of 38 patients,anchor segments was C3,5,7,using 3 anchoring nails.The improvement rate of nerve function,ranges of neck motion,incidence of axial symptoms and postoperative complications were compared between two groups.Results The improvement rate of nerve function,loss of ranges of neck motion and incidence of axial symptoms between group A and group B had no significant difference[(56.4 ± 18.3)% vs.(56.8 ± 19.6)%,(9.27 ± 5.42)° vs.(9.06 ± 4.89)°,22.9% (11/48) vs.23.7% (9/38)] (P > 0.05).Two groups of patients with postoperativefollow-up were not found door re-clousure phenomenon.Conclusions In the anchor posterior unilateral open-door laminoplasty,they have same improvement rate of neural function on anchoring 3 segments and anchoring 5 segments.The postoperative complications are not increased,but the cost of internal fixation is decreased,operation become more economical.
