Single open door laminoplasty with lateral mass screw fixation and bone graft in the treatment of the patients with cervical spinal cord compression
Abstract：Objective To investigate the clinical efficacy of single open door laminoplasty with lateral mass screw fixation and bone graft for the treatment of cervical spinal cord compression.Methods From February 2004 to June 2008,the single open door laminoplasty with unilateral lateral mass screw fixation and bone grafting was used to treat 26 patients with cervical spinal cord compression,including 18 male patients,8 female patients ;aged 51 to 67 years old ;the average age was 58 years old. Among 26 patients,there were 22 patients suffered multi-segmental cervical spondylotic myelopathy(three or more than three segments). Of them 10 patiens complicated with developmental spinal stenosis,6 patients with power spinal stenosis,3 patients with ossification of posterior longitudinal ligament,one case was traumatic. Another 4 patients suffered from the cervical spinal canal tumor. Follow-up time was 9 months to 26 months,with an average of 20 months. Results The efficacy were evaluated by reference to Japan Association of Plastic Surgery (JOA) score standards. There were excellent in 8 patients,good in 15 patients,fair in 2 patients,poor in 1 patient,the excellent and good rate was 88.5%. No patient had vascular injury or internal fixator fracture,one patient with meningioma occurred spinal cord ischemia-reperfusion injury ofter operation due to too large tumor, the disease cordition was improved by active treatment,and had self-care ability.Conclusion The method can be applied to the patients with cervical spinal cord compression required to carry out posterior,and its efficacy is positive. The advantage is the relative safety of surgery,simultaneous performance of a thorough decompression and a strong fixatiom. It is applied particularly to treat the patients with cervical spondylotic myelopathy complicated with segmental instability.
