摘      要：Background：Posterior cervical decompression is an accepted treatment for multilevel cervical spondylotic myelopathy （CSM）.Each posterior technique has its own advantages and *** the present study,we compared the functional and radiological outcomes of expansive hemilaminectomy and laminoplasty with mini titanium plate in the treatment of multilevel ***：Forty-four patients with multilevel CSM treated with posterior cervical surgery in Department of Orthopedic Surgery,Beijing Army General Hospital from March 2011 to June 2012 were enrolled in this retrospective *** were divided into two groups by surgical procedure：Laminoplasty （Group L） and hemilaminectomy （Group H）.Perioperative parameters including age,sex,duration of symptoms,opcrative duration,and intraoperative blood loss were recorded and *** canal area,calculated using AutoCAD software（Autodesk Inc.,San Rafael,CA,USA）,and neurological improvement,evaluated with Japanese Orthopedic Association score,were also ***：Neurological improvement did not differ significantly between *** H had a significantly shorter operative duration and significantly less blood *** expansion ratio was significantly greater in Group L （77.83 ± 6.41%） than in Group H （62.72 ± 3.86%） （P 〈 0.01）.Conclusions：Both surgical approaches are safe and effective in treating multilevel *** provides a greater degree of enlargement of the spinal canal,whereas expansive hemilaminectomy has the advantages of shorter operative duration and less intraoperative blood loss.
