摘　　要：目的:比较山羊与人颈椎的体外三维生物力学特征。方法:取新鲜成年人尸体与崇明山羊颈椎标本(C0～T1)各8具,在脊柱三维运动测试仪上检测两者屈曲、后伸、左右侧屈、左右轴向旋转等模式下的运动范围和中性区。结果:在前屈运动方式下,山羊和人C1-2的ROM分别为16.9°±5.1°和14.3°±3.2°,超过其它节段。在后伸运动方式下,山羊与人C1-2的ROM分别为20.6°±4.8°和18.7°±3.7°,C0-1的ROM分别为19.3°±4.7°和18.4°±4.3°,超过其它节段。在轴向旋转运动模式下,山羊与人C1-2的ROM分别为48.6°±8.6°和56.3°±8.9°。除山羊C6-7左右侧屈的NZ与人相比有统计学差异(P<0.05)外,其它节段前屈、后伸、轴向旋转及左右侧屈的ROM和NZ与人相比无统计学差异(P>0.05)。结论:崇明山羊与人颈椎在前屈、后伸、左右侧屈和轴向旋转等运动模式下的ROM及NZ相近,可作为颈椎研究的良好动物模型。Objective To compare the three-dimensional biomechanical characteristics between goat and human cervical spines. Methods： 8 flesh cervical spmes were harvested respectively from adult human cadavers and Chongming goats. The range of motions （ROM） and neutral zone （NZ） of the specimens were tested respectively in three-dimentional testing apparatus under flexion, extension, right or left bending and axial rotational loads. Results： Under flexion loads, the ROM of C1-2 of goats and humans was 16.9°±5.1° and 14.3°± 3.2° respectively, lager than that of the other levels. Under extension loads, the ROM of C1-2 of goats and humans was 20.6°±4.8° and 18.7°±3.7° respectively, and ROM of C0-1 of goats and humans was 19.3°±4.7° and 18.4°±4.3° respectively, more superiorly than that of the other levels. Under axial torques, ROM of C1-2 of humans and goats was 48.6°±8.6° and 56.3°±8.9° respectively. However, the ROM and NZ of all segments of goat under three-dimensional loads had no statistical significance respectively when compared with human （P〉0.05） except for the NZ of C6-7 level under right or left bending torques. Conclusions： Chongming goat has similar biomechanical characteristics with human under flexion, extension, right or left bending and axial rotational loads. It can be served as an optimal model for cervical research.
