Abstract:
Objective To evaluate the efficacy of unilateral open door laminoplasty and individualized cervical pedicle screw fixation for multisegmental cervical spondylotic myelopathy with flexibility type kyphosis.Methods Twenty one cases of multisegmental cervical spondylotic myelopathy with flexibility type kyphosis received surgical treatment.Unilateral open door laminoplasty and individualized cervical pedicle screw fixation.The Japanese Orthopaedic Association ( JOA) scoring system and disability index ( NDI) were applied to evaluate the neurological function and axial neck /shoulder pain before and after surgery.The Borden′method was employed to measure the cervical curvature.CT plain scan of cervical pedicle and sagittal two-dimensional imaging of transpedicular on the axial was examined.The unilateral open door laminoplasty and individualized cervical pedicle screw fixation was performed .Results A total of 168 pedicle screws were fixed successfully in 21 patients, the accuracy of screw placement reached 93.5%.The cervical curvature measured by Borden′method showed significant differences before and after operation.Compare to those before surgery , the JOA scores at 1 week after operation and at final follow-up were decreased and NDI scores were significant increased ( P <0.05 ).Conclusion Unilateral open door laminoplasty and individualized cervical pedicle screw fixation is effective for treatment of multisegmental cervical spondylotic myelopathy with flexibility type kyphosis.
