【摘要】 目的探讨脊髓型颈椎病患者术前MRI测量脊髓受压程度与手术预后的相关性。方法收集55例行颈椎前路手术的脊髓型颈椎病患者术前磁共振资料,测量其受压节段横断面面积(TA)、脊髓压迫率(CR)、最大脊髓退让率(MSCC)、最大椎管侵占率(MCC)四个指标,记录术前与术后2年改良JOA评分和JOA评分改善率,采用SPSS 19.0软件分析术后2年JOA评分改善率与TA、CR、MSCC、MCC、年龄、性别及病程等指标的相关性。结果单因素分析显示,年龄、CR、MSCC、MCC与术后2年mJOA评分改善率具有相关性;多元线性回归分析显示:年龄、CR、MSCC影响术后2年mJOA评分改善率。结论术前脊髓CR、MSCC指标与年龄,均是手术预后的影响因素。更多还原

【Abstract】 Objective To investigate whether findings on preoperative magnetic resonance imaging(MRI) could predict recovery of cervical spondylotic myelopathy(CSM) patients at 2 years.Methods A total of 55 patients underwent MRI before anterior cervical decompression and fusion surgery.Patients were followed clinically and evaluated using the modified Japanese Orthopaedic Association(mJOA) scoring system 2 years after surgery.The measurement parameters[transverse area of spinal cord(TA),compression ratio(CR),maximum spinal cord compression(MSCC),maximum canal compromise(MCC)] were measured before surgery.The correlation between the parameters and the improvement rate of clinical symptoms was analyzed by SPSS statistics 19.0.The most useful combination of parameters for predicting prognosis was determined using a stepwise multivariate regression analysis.Results The functional recovery ratio was associated with MSCC,MCC,and CR.Using stepwise regression analysis,the functional outcomes after surgery were best predicted by age,CR,MSCC.ConclusionFindings on preoperative MRI has predictive value in determining postoperative functional recovery in CSM patients.Patients whose cord failed to reexpand have a poorer recovery rate.更多还原
