目的：测量成人上胸椎T1～T6椎板解剖学参数，探讨上胸椎椎板螺钉内固定的可行性。方法取21具成人T1～T6的干燥标本（不分男女），用游标卡尺和量角器测量其椎板的解剖学数据，包括椎板高度（H）、厚度（T）、宽度（W）、钉道长度（L）、外倾角（angle A）。结果21具成人尸体T 1～T 6节段椎板高度、厚度、宽度分别为16.48～21.20 mm、6.33～6.90 mm、6.68～10.18 mm，椎板外倾角为51.7°～55.9°，钉道长度为36.00mm～26.60mm。解剖学左右侧对比，差异无统计学意义。结论上胸椎椎板螺钉具有解剖学可行性，有可能作为上胸椎后路固定的一种替代或者补救方法。

Objective To measure anatomic data of laminar from T1 to T6, and evaluate the possibility of laminar screw placement in the upper thoracic spine.Methods The anatomical parameters which were related to laminar screw placement in the upper thoracic spine were measured in 21 adult cadaveric specimens of T1 to T6 segment by vernier caliper and protractor.these data included the laminar height、thickness、width、camber and the trajectory length of laminar screws.Results The height、thickness and width of vertebral laminar of T1 to T6 segment of the 21 adult cadavers ranged from 16.48mm to 21.20mm、from 6.33mm to 6.90mm and from 6.68mm to 10.18mm, the laminar camber and the trajectory length of laminar screws ranged from 51.7° to 55.9° and from 36.00mm to 26.60mm.There was no statistic difference on the data of cadavers between left and right.Conclusion Laminar Screw Placement is feasible,and this could be used as a supplementary method for conventional posterior screwfixation techniques in the upper thoracic spine .
