目的：推导单开门椎板成形术中开门角度与椎管面积增加值关系的公式，根据椎板开门距离预测椎板开门角度。
方法：2013年1月至2015年12月，行颈后路C3-C7单开门椎板成形术26例，其中颈后纵韧带骨化症10例，男6例，女4例；年龄39~58岁，平均49.2岁。脊髓型颈椎病16例，男10例，女6例；年龄40~58岁，平均50.2岁。通过术前术后的椎管形态变化，建立规则几何模型，分别推导出椎板开门角度与椎管面积增加值关系公式、预测椎板开门角度公式。通过患者手术前后CT片，测量公式中所需参数，并代入公式得出手术前后横截面积变化和预测开门角度，通过统计学方法分析手术前后横截面积变化和预测开门角度及实际测量角度之间差异，从而验证公式在实际应用中的可行性。
结果：26例病例均获得影像学资料。对每个病例C3-C7节段术前术后椎管横截面积进行逐一对比，均有统计学意义（P<0.01），但随角度增加横截面积的增加幅度逐渐减少。通过公式所得各个节段预测开门角度值与实际所测的角度值逐一进行对比，差异无统计学意义（P>0.05）。
结论：在单开门椎板成形术中，应用公式根据开门角度能准确计算椎管横截面积增加值，并能准确预测椎板开门角度，从而指导术者准确获得理想的椎板开门角度，减少术后并发症。 |

Abstract:
Objective To evolve the formula of relationship between opening angle of laminoplasty and the increased value of cross-sectional area,and to predict the opening angle according to the opening size of lanminoplasty.
Methods: From January 2013 to December 2015,26 patients underwent single open-door laminoplasty in C3-C7. Among them,10 patients with ossification of posterior longitudinal ligament,there were 6 males and 4 females,aged from 39 to 58 years old with an average of 49.2 years;and 16 patients with cervical spondylotic myelopathy,there were 10 males and 6 females,aged from 40 to 58 years old with an average of 50.2 years. Through the changes of spinal canal shape between preoperation and postoperation to set up the regular geometric model,and to deduce the formula of the relationship between the opening angle of laminoplasty and the increased value of cross-sectional area,and predict the formula of opening angle. According to the preoperative and postoperative CT scan,the needed parameters were measured,and were substituted in the above formula to get the change of cross-sectional area before and after operation,predicting the opening angle of laminoplasty. The differences between the change of cross-sectional area before and after operation,predictive the opening angle of laminoplasty and practical measured data were analyzed by statistical methods,thus to verify the feasibility of formula in practical application.
Results: All imaging data of 26 patients were obtained. There were significant differences in changes of cross-sectional areas in every patients (laminoplasty in C3 to C7) before and after operation in the same segment(P<0.01). The increasing extent in cross-sectional areas was gradually diminished following the opening angle increasing. There was no significant difference between the opening angle attained by formula and the data measured by software in the same segment(P>0.05).
Conclusion: Increment of cross-sectional areas following C3-C7 laminoplasty can be accurately attained and the opening angle can also be predicted by a certain formula,which can help surgeons to attain the accurate opening angle and reduce the postoperative complications. |
